The Addict has been a staple of Scott’s street lineup since 2007 when its unique light-weight shape emerged as a climber’s best friend and some of the favourites at the WeightWeenies discussion board. This new Addict – the 5th technology of the platform – is unquestionably a motorcycle that may pique the hobby of weight-obsessed cyclists.
The headline driven by way of Scott on the motorcycle’s press release in Girona used to be that the Addict RC Final is the lightest manufacturing street motorcycle available on the market. The highest-spec Final fashion guidelines the scales at a remarkably feathery 5.9 kg for a length medium. This weight is much more spectacular while you in finding that it’s fitted with 28 mm tyres, deep-section wheels, and a nod to aerodynamic design. As is increasingly more not unusual with even ultralight motorcycles, the Addict isn’t purely one-note, as Scott claims it’s as slippery within the wind because the previous-generation Foil aero street motorcycle.
I’ve controlled simply a few rides at the new Addict RC and feature most effective simply gained a motorcycle for additional trying out on acquainted roads. A complete overview will are available in long run, however for now, right here’s what to learn about this new flyweight device at the side of some early impressions.
The lengthy street again to sub-6 kg
The 5.9-kilo benchmark that Scott used to be taking a look to succeed in used to be additionally a thought to be quantity that harks again to the unique Addict RC, which additionally tipped the scales underneath 6 kg. In fact, again then street motorcycles had been an excessively other affair. Integration used to be an alien phrase to motorcycle designers, disc brakes had been the reserve of mountain motorcycles, anything else aerodynamic used to be in its personal magnificence of motorcycle, and battery-powered derailleurs had been nonetheless two years away. For a time it used to be simple to hit the UCI’s 6.8 kg minimal weight prohibit, however even with the combination development, the adoption of hydraulic disc brakes and a focal point on aerodynamics intended fewer motorcycles approached that threshold. The Addict re-breaks the barrier in a large manner.
The unique 2007-era Addict RC weighed 5.9 kg, which was the objective for the brand new Addict RC.
The brand new Addict RC is said to have taken 4 future years in combination. Max Koenen, engineering mission lead at the Addict RC mission, mentioned, “Through fashionable requirements, a race motorcycle has some necessities which upload weight to a complete motorcycle, which we had to save at the frameset. Some examples are hydraulic disc brakes, digital team units, huge tyres with right kind grip and massive cassettes. These types of issues are including weight to all the motorcycle.
“We had been asking ourselves, ‘Are we able to do this once more? Are we able to construct a motorcycle on the identical weight prohibit or on the identical weight because the 2008 fashion?’ And we had been beautiful satisfied about that as a result of, inside those 15 years, issues have modified – now not most effective the necessities but additionally the improvement processes and likewise the applied sciences.”
The core design targets the group at Scott settled on for the Addict RC had been to create a sub-600 gram body, be the brand new benchmark in integration, toughen each aerodynamics and luxury while maintaining stiffness, and do all that while expanding tyre clearance to 34 mm. In keeping with the corporate, each part of the Addict RC has been analysed to systematically take away weight the place imaginable.
Addict RC in its preproduction livery.
At a look, the silhouette of the brand new Addict RC is paying homage to the former fashion, albeit with a couple of tweaks. Via their very own trying out, Scott discovered that the Addict RC used to be 12 watts quicker than the outgoing fashion and 9 watts slower than the newest Foil RC at 45 km/h. The aero enhancements, particularly across the head tube of the motorcycle, imply that the Addict RC is claimed to be as aerodynamic because the previous-generation Foil.
Tailored geometry for wider tyres
Probably the most key tendencies the design group seen all through the design procedure used to be the expanding use of wider tyres in skilled racing. Riders had been particularly shifting in opposition to 28-30 mm tyres for many races, with even higher sizes being desired for particular occasions like Paris-Roubaix and Strade Bianche. To look forward to the development of this pattern, the group set the objective of 34 mm tyre clearance for the brand new Addict RC. In keeping with the logo, the motorcycle can settle for even wider tyres than this when constructed with a SRAM groupset, because the proscribing issue on Shimano builds is the clearance between the tyre and the entrance derailleur.
However merely expanding tyre clearance with out adjusting the geometry negatively impacted the motorcycle’s dealing with and function. To deal with this factor, Scott carried out a number of key geometry adjustments in an effort to retain the Addict RC’s race center of attention with 30 mm tyres fitted.
The Addict RC has clearance for 34 mm tyres.
At the beginning, becoming wider tyres lifts the motorcycle increased off the bottom, transferring the centre of gravity upward. So the ground bracket has been dropped to compensate, maintaining the ground bracket place relative to the bottom in comparison to the former fashion Addict RC.
On the entrance of the motorcycle, the fork’s geometry has been overhauled with an extended fork rake. With higher-volume tyres fitted, the path of the fork naturally will increase, slowing down the responsiveness of any enter. The longer-rake fork lets in the path to be diminished to stay the motorcycle’s agile feeling and responsive dealing with, specifically on descents. A lucky knock-on impact is that the longer rake positions the entrance wheel farther clear of the rider’s ft, fighting toe overlap – one thing that smaller riders will likely be specifically happy to listen to.
The fork has an extended rake to deal with the fork’s path with higher tyres.
To counteract the greater wheelbase of the longer fork rake, the group shortened the chainstays to 410 mm, the minimal size approved for compatibility with Shimano rear derailleurs. To toughen the tyre clearance, the group shifted the seat tube ahead by way of 5 mm after which provided a 5 mm offset seat publish to deal with the unique saddle place relative to the ground bracket.
HMX and HMX-SL Frames
There are 5 fashions within the Addict RC differ. 4 of the fashions (RC30, RC20, RC10 and RC Professional) all use the similar HMX carbon fibre chassis with the body weighing a claimed 650 grams for a medium body length and 295 grams for the fork. This can be a 172- and 49-gram saving, respectively, over the previous-generation Addict RC. This brings the HMX body 35 grams underneath the claimed weight of Specialised’s S-Works Tarmac SL8. On the other hand, this quoted body weight from Scott used to be for an unpainted body with the completed body with paint round 40-50 grams heavier than this for the Final and round 70 grams for the colourways at the Professional and under fashions.
The RC Final steps issues up the use of the logo’s higher-modulus HMX-SL carbon fibre layup. The Final framesets also are manufactured in a separate facility that makes use of a brand new building procedure that is helping facilitate the additional relief in chassis weight. A part of this new procedure lets in for the membrane used within the fork’s building to now be got rid of. Till now the tight and complex inner profile of the fork intended that the membrane used to be left in situ. This procedure saves only a handful of grams, however on a motorcycle like this each gram that may be stored is a transfer nearer to the 5.9 kg goal.
The Final body is available in at 599 grams with a fork weighing 270 grams. This can be a 161- and 54-gram saving over the outgoing RC Final. For reference, Specialised claims that the S-Works Aethos body is available in 14 grams lighter at 585 grams.
The vitamin hasn’t been limited to simply the body and fork. with an extra 253 grams shaved off the 2022 fashion in the course of the accompanying (proprietary) parts. The result’s a complete saving in comparison to the prior variations of 474 grams for the HMX construct and 468 grams for the top rate HMX-SL. The former Addict RC used to be rarely a heavyweight, so the saving of just about part a kilogram (a complete pound) is an excellent feat.
A part of the body’s crash vitamin used to be completed via in depth FEA (Finite Part Research). Via this system, Scott realized that the seat tube may well be redesigned to avoid wasting weight. At the preceding technology Addict RC, the seat tube used to be a uniform thickness right through. At the new Addict RC, the seat tube is thickest across the clamping house prior to it reduces in thickness farther down.
Scott engineer Patrick Lüthi went into element appearing the FEA design procedure that resulted in the refinement of the RC body and the way the burden relief used to be completed.
As some of the first manufacturers to transport to press-fit backside brackets, Scott is sticking with the era, on this case, a PF86. Scott believes that robotically that is the most productive (and lightest) resolution for mounting bearings on this house as long as the producing tolerances are managed.
One bolt to rule all of them
Previous within the 12 months the brand new Canyon Aeroad presented a unmarried bolt length around the motorcycle. With the Addict, Scott has adopted swimsuit, adopting a one-tool-to-adjust-everything technique. The bolt it settled on is a T25 Torx because of its talent to resist top torque enter while being compact sufficient to nonetheless paintings throughout all of the spaces of the motorcycle.
Against this, Scott claims that to succeed in the similar energy homes the use of a hex head bolt the default length would wish to be 6 mm, a length deemed impractical and a bit of unsightly for goal. The one house the place a T25 used to be now not used is the axles which game an ordinary 6 mm hex head.
A small Torx instrument hid within the bar plug is all you want to regulate all of the bolts at the Addict RC.
This one-size bolt technique lets in for a very easy instrument for use to regulate any of the motorcycle’s fasteners. Except for the Final HMX-SL construct, all Addict RC fashions come with a small bar end-mounted multi-tool that gives the desired T25 Torx and six mm hex gear.
Good-bye, Contessa
The discharge of the Addict RC indicates the top of the street for Scott’s females’s-specific differ. Contessa used to be the title given to the logo’s women-specific fashions; then again, the logo feels that heading to a fully unisex differ going ahead is the most suitable choice for giving all riders the selection of spec and color they would like. It’s a choice that apparently follows the likes of Specialised and Trek, which additionally discontinued their females’s-specific levels and as a substitute broadened the overall differ.
The Addict is a unisex differ with Scott finishing the Contessa programme.
Charlotte Pythoud, graphic dressmaker for the Addict RC programme, used to be a part of the Contessa programme prior to now, however extra lately used to be a voice pronouncing it must forestall. When requested why, she defined, “For me, the fashion isn’t pronouncing it is a girl’s product and it is a guy’s one. I believe it’s extra what’s trending, what’s in type. We attempt to nonetheless have that female contact however that female contact isn’t all the time for ladies and you notice the similar with jersey colors when it modified like 10 years in the past.”
Pythoudi additionally defined that many males at Scott have been opting for to trip Contessa motorcycles merely as a result of the most popular aesthetic. For staff of the logo, this transfer is definitely justifiable however to the patron marketplace, convincing males that they may purchase a ‘females’s particular’ fashion in the event that they most popular the colourways on be offering can be a some distance tougher job. As a substitute bringing every thing underneath one differ provides everybody the liberty to make a choice precisely what they would like.
The Contessa differ traditionally used the similar chassis as its corresponding Scott counterpart – albeit with a distinct construct package, worth level, and colourway. Pythoudi defined that this will really feel proscribing for feminine cyclists who don’t really feel they may get a top-of-the-range motorcycle because the Contessa differ crowned out with mid-tier builds.
Color samples used within the graphic design procedure for the Addict RC that attraction to each female and male riders.
The emblem believes that shifting to a unisex product differ opens up all designs to all consumers and creates a extra open and out there differ for any rider. Talking concerning the broader biking marketplace, Pythoudi defined, “As a girl, I’m all the time pissed since the females’s factor is made in purple or blue and it’s additionally affordable as a result of [the assumption is] females need to purchase inexpensive merchandise. We don’t want it in motorcycles as it’s the similar product on the finish, you’ll be able to purchase no matter you wish to have and this fashion you’ll be able to attempt to fit as many shoppers as you wish to have.
“In fact, sellers have to reserve accordingly in the event you take into consideration sizes as a result of if they suspect it is a product that’s going to be offered extra to girls, then you definately even have to reserve extra additional small and double additional small motorcycles. We attempt to be offering as large [a range] as imaginable to in point of fact fit as many of us as imaginable for each men and women. In truth letting Contessa move allow us to have extra of this type of trendy colourways that don’t seem to be just for females but additionally at the next degree,” Pythoudi added.
A relaxed motorcycle is a quick motorcycle
The Scott design group repeated the message that not anything at the new Addict RC used to be accidental. A space the place this intent used to be specifically noteworthy used to be across the junction between the seat remains and seat publish. Because the seat remains go back and forth clear of the dropout they gently roll inwards. That is aesthetically very enjoyable and creates a clean transition into the seat publish, then again, the explanation at the back of this runs some distance deeper than appears to be like.
The seat remains have a slight rotation in them to assist compliance.
Via Scott’s inner trying out when analysing body compliance, they discovered that the flex of the seat remains doesn’t actuate within the vertical axis. As a substitute, the flex happens laterally with the chainstays bowing outwards underneath have an effect on and vibrational a lot. That figuring out allowed the engineers to maximize compliance while maintaining the stiffness anticipated of a top rate race motorcycle.
Scott has provided the motorcycles with a Syncros Convenience seat publish for all fashions with the exception of the Final and Professional. A cutout in opposition to the highest of the publish can match a magnetic rear mild or simply have a fairing positioned over it. It is extremely very similar to the publish discovered at the present technology Foil, albeit a bit of shallower. It’s a small-seeming factor, however this cutout design is said to extend compliance on the saddle by way of 36%.
New Schwalbe rubber breaks quilt
There used to be little that will be disclosed concerning the tyres discovered at the Final. From afar they give the impression of being similar to some other Schwalbe One Professional tyre we now have grown familiar with. Upon nearer inspection, the tyres are marked up as ‘Aerothan,’ sharing its title with the logo’s Aerothan TPU inside tube. The Addict marks the tyre’s first look.
Precisely what Schwalbe has advanced with this new tyre will likely be published at a later date by way of the logo themselves. What I will let you know is that the Aerothan tyre isn’t tubeless-ready, which means that that it should be run with an inside tube. Naturally, Schwalbe recommends the Aerothan tube and says that this setup provides minimum rolling resistance and is the lightest setup.
Schwalbe’s Aerothan tyre is 29mm in precise width however is marked up as 28mm.
This can be the case however having a tubed tyre on a hookless rim turns out love it is looking for bother. It’s already a minefield in terms of figuring out the ETRTO most force limits and including an inside tube into the combination unquestionably gained’t do anything else to ease this. Without reference to tubeless or inside tube setups, the ETRTO max force of five bar (72.5psi) on a hookless rim should be abided by way of.
Extra will likely be published in just right time when Schwalbe stocks additional main points at the Aerothan tyre however my non permanent preliminary affect is the tyre is confidence-inspiring on descents or even with the tubed setup no person at the 20-strong press commute were given a puncture so there’s something to be mentioned for that.
Construct kits and pricing
The Addict RC Final that I spent probably the most time on is the logo’s flagship fashion with a construct package and worth worthy of flagship standing. Completing off the HMX-SL frameset is a mixture of Syncros parts (together with a brand new one-piece cockpit), Syncros Capitol SL wheelset, and SRAM’s Pink AXS groupset with Quarq energy meter.
Becoming a member of the Final are 4 different builds that each one use the HMX body and Shimano groupsets. The RC 20 and 30 additionally use a two-piece bar and stem somewhat than the totally built-in IC-R100-SL cockpit discovered at the pricier fashions.
The Addict RC Professional is constructed to return in waiting to race on the UCI’s 6.8 kg minimal weight prohibit as soon as pedals and cages are fitted. Shimano’s Dura-Ace Di2 looks after transferring while the Syncros wheelset takes a step all the way down to the Capital 1.0S 40 mm wheels. Those are extra conventional of their spoke and rim design than the single-piece building of the SL’s. One thing that the Final omits within the seek for absolute weight weenie standing this is provide on all different fashions is a small Torx/Hex instrument enclosed within the bar finish.

The Schwalbe Aerothan tyres are most effective discovered at the Final construct with Schwalbe’s Professional One and One tyres coming suited for the remainder of the variety. The Final could also be the one fashion to return with 28c tyres with the remainder of the variety choosing 30c tyres to extend convenience.

First trip impressions
I most effective rode the Addict RC a couple of occasions all through a press release in Girona, so I’ve but to completely acquaint myself with the motorcycle. For that, a full-length overview is within the works for the approaching months.
My revel in with such mild motorcycles is that they are able to really feel a bit of skittish, or a minimum of lack a planted really feel. Against this, the preliminary feeling of the brand new Addict RC used to be simply how composed it felt. For the reason that the primary 400 meters of the trip had been down a 16% hill via quintessentially tight Spanish again streets I used to be inspired to really feel at house so temporarily.
Descending at the Addict used to be composed and predictable.
Urgent at the pedals there may be an immediacy to the hassle being transformed to ahead movement. At decrease energy, the Addict RC is relaxed with out a harshness transferred in the course of the bars or saddle. I discovered that I used to be many times leaping out of the saddle on quick punchy rises to revel in how the body’s stiffness converts rider enter to movement. Taking the Addict RC Final into its house terrain, the motorcycle demonstrated that there used to be extra to it than simply low weight that made it an outstanding mountaineering device. The enhanced compliance gave me the sensation of separating myself from the street in some way that allowed me to easily center of attention on making use of energy to the pedals.
Even though the intentions of a light-weight motorcycle are obviously aimed toward serving to to cheat gravity, the place the Addict RC inspired me maximum used to be when heading back off. Descending at the Addict RC used to be a composed and predictable affair that took little or no time to heat to. The mix of the wide-sitting 28 mm (quoted width) tyres that had been fitted and the decreased backside bracket intended that I may totally extract the grip that the Addict-exclusive Schwalbe Aerothan tyres be offering.
It’s going to be fascinating to get a while with a leg over the Addict RC Final on less-favourable UK roads to look the way it stacks up on damaged and grimy asphalt. My assumption when using the Addict used to be that the Syncross Capitol SL 40 mm wheels and the unique Schwalbe rubber had been liable for a big portion of the motorcycle’s total traits. I’m taking a look ahead to getting a while to position a collection of extra moderate wheels at the motorcycle to check out and quantify simply how large the function of the wheels and tyres has at the Addict RC.
Separating the trip really feel of the motorcycle will likely be some of the first assessments at the time table. Swapping the Capital SL wheels out and trying out the motorcycle with a collection of Rovals will shine some mild on how a lot of the heavy lifting the wheelset is contributing to the total really feel of the motorcycle. Again-to-back trying out of the Addict RC in opposition to a Tarmac SL8 with every motorcycle configured with each the Capital SLs and the Rovals must supply an purpose comparability.
With the Contessa Programme finishing, Suvi has additionally taken supply of an Addict RC, permitting us to check the motorcycle collaboratively. Throughout two other body sizes from two other views, stay a watch out within the coming months for this complete overview of the Final fashion.
