Hi all! I am so newbie here but to my findings, there few few slide rollers in market while Dr pullley and Malossi seem stand out from the rest. Which one fits best for c600? Best here signifies the durability, longevity, mid to top acceleration, etc. Appreciate advices especially on the best value for money. Many thanks.

This is a good read about JCosta Variator vs Dr Pulley Sliders / Hit Clutch.
I have been pondering about this for sometime now... Since e 3 components mentioned above all improve acceleration and/or top end speed, no one has touched on e effect it has on e V-Belt.Correct me if i'm wrong but when u have for instance, a hit clutch or e JCosta/Dr Pulley variator installed,wouldn't it affect e lifespan of e V-Belt as it's now subjected to more stresses/abuses since e clutch engages much earlier and a more immediate transfer of power to e rear wheel is felt??
I bought what most of u did,e "Best Bang For Your Buck" 28g Dr Pulley sliders but hv yet to install it cos i'm considering e Hit Clutch as well but e BMW agent here is not that supportive of e aftermarket parts replacement which is a known issue and e labour charges are ridiculous here in e tiny island of Singapore. I'm still on their 2yrs warranty so i wouldn't wanna push them so much.
So in short,i would like to know if having e hit clutch n 28g slider combo will affect e lifespan of e V-Belt and e F/C otherwise i'll just install e sliders as my brakepads,tyres and 20,000km servicing is coming up next month n i'll try coax e agent to fix it for me as well.Thanks and sorry if this has been mentioned somewhere... Cheers

Everything should last longer.The HIT Clutch and Sliders might NEVER need to be replaced in the life of your bike, they wear that little!
People have taken them out to inspect with a belt change thousands of miles later and found essentially NO WEAR.
Didn't know they can last that long... That's good news then! Anyway,i had a chat with e BMW service manager e other day about installing e 28g sliders and he was blabbering non-stop about e sliders affecting other components and stuff which i think is just crap! He's just making it damn difficult for me. After chatting for about 30mins or so,he finally caved in to my sweet-talk and told me to bring e sliders when i come in for my 20,000km service which is just round e corner... Phew!

Can't wait to collect my bike this Thursday! After reading all e reviews, i'm getting excited! Just last week,I installed Dr Pulley Sliders on my gf's Gilera VXR200 and it made e bike "playful" now... Simply loved it!

Question (not being a wise-ass): If I am happy with my bikes performance why would I want to add new sliders? I've been reading about these things from guys that know stuff, and am thinking about taking the bike in to my dealer and having the changes made, but in all honesty, I really like they way my C650GT runs now.
Or is all this part of that rowdy C600 crowd shenanigans that deal with "speed and more speed"?

Not that this thing is not fast but having that extra umph in acceleration throughout all revs definitely feels good! For such a cheap mod I am amazed with the results on my Gilera. I just wish I had done it earlier. I feel this is how the bike should have been from the factory.Hee...!

I'm all smile from ear to ear now! e Dr Pulley sliders really transform my bike into a playful scooter now and anything above 50km/h seems very quick...! I'm loving it! Thanks to all those who have answered my queries and thanks Skutor!
Did you have the dealer do the mod or did you diy. If the dealer may I ask how much?

I had e dealer to install it for me... e installation charges for e replacement of CVT belt n roller(to sliders) alone is already SGD162(USD129). I'm from e tiny island of Singapore.

Joe is in Singapore. Neither the Aurora dealer or Sills has an outlet there.
I am going have some Dr. Pulley's added when I get the chain tensioner done. At that point I will go to Dr. Skutorr to verify any other gadgets that might be needed. (Just one more benefit of this forum.)

Hmmm, that makes sense to me (which means nothing from a mechanical knowledge point of view). Earlier in the thread it was mentioned that top speed was not compromised and, in fact, could be achieved quicker according to the reviewer from the Italian site. But getting there quicker and staying there longer are two totally different things. (Working real hard at having my maturity kick in after writing that.)
Here's a comment from a Dr. Pulley vendor...

Skutorr,could u explain this further? Am i right to say that as compared to e stock 33g rollers,these 28g sliders will get u to e desired speed faster and also at a LOWER RPMs?

The wedge shape of the slider allows the variator to actually open a bit wider at rest, dropping the belt into a smaller circumference between the variator halves, essentially lowering your gearing from a start and helping with off the line acceleration. As they are lighter than stock, your bike is revving higher, closer to it's torque peak and can apply more force through that lower gearing, hence the two-pronged increase in performance.
The same wedge shape also does the converse, at high speed, forcing the variator halves closer together than before, effectively raising your gearing and lowering rpms, even with lighter weights. Brilliant design.
The standard rollers (which actually also slide, not "roll", are fixed diameter, with taller gearing from the start and lower gearing at speed...
