I was running 12 gram rollers and since it was time to do a belt change, I figured I'd try a set of sliders. So off to the local Scooter shop I went. Bought my gates powerlink and a set of Scoot Ninja 11 gram sliders. I already have a 115MM Hoca variator and the 12 gram rollers that came with the varator and they seem pretty close to the ball park. The bike I ride is pretty light, but I am 300lbs so the bike does work hard so with a lighter rider, the 12 gram roller may be a little light.
At first, I didn't notice a big difference when I test drove it after changing the belt and putting in the sliders. Most of my test drive was on a straight road so I usually just flog the heck out of it. What I did notice it was alot smoother and it would get to the power band a lot quicker. Then I got the bike around a few corners and WOW, the bike would be right in the power band when you rolled back on the throttle and on the whole, made the little bike a lot more fun. I'm not going to say I carve canyons or anything, but I do lean the bike a bit and so being able to get a little more out of turn really fits my riding style... Then I noticed on the way home (it's about 30 miles from my buddies place where I changed the belt) that while my take off speed was pretty close to the same, if I had to let off the throttle, then get back on the throttle, the bike was way more responsive. I didn't lose top speed either, something I was concerned about going to the lighter weight. Climbing overpasses is better to. The bike feels more capable, and competent.
All and all, I'm really happy with my cheap mod ($25.00 set of sliders).
I then let my friend ride it, he is also a 300lbs rider and he rides a later version of my bike. He was like wow... Do what you did to your bike, to my bike. I think that is a great complement.

Going down a size you should have noticed a huge difference! Sure they're in right?
I love my sliders. I had to stay the same weight as the stock rollers or my rpms pegged too high. Yours should be higher as well??

I don't have a stock variator so the 12 gram roller weights worked pretty well but the sliders do a better job of keeping it in the powerband, again I'm a heavy rider on a 10" wheeled scooter. 1 gram on sliders usually only make a 500rpm change and yes, they are in right, I double checked the diagram when I put them in. They are doing their job, keeping the bike in it's power band. It's damn near perfect at this point. It just didn't make too big a difference on take off is all. Where I really noticed is in the turns and anytime I roll back on the throttle. What made a huge difference on take off was going from a stock 107mm variator with 14gram weights to a 115mm variator with 12gram rollers. That was a huge difference.
There are so many variables and every bike, rider combo is different.

That Hoca variator of itself makes a big difference over stock and just putting in new 12 gram rollers may have been noticable too.

Yes it did.... Changing to the Hoca and 12 gram rollers did make a huge difference. It was the set up I ran for 3000 miles.... Sliders make it even better. It is just a sweet running set up.

I replaced my 12.2g rollers at 5,500 miles with 12g Dr Pulley sliders and gained 5 MPH . A lil over 13k miles they have worn down so I will be trying 13g DR Pulley sliders this week and see what top speed will be with a new variator too

I really think tuning the variator and changing weights is the biggest bang for the buck on the 150cc bikes. In my case, the Hoca unit really helped and it's fairly easy. On another bike, I did a exhaust, and a uni, and it didn't make nearly the difference the variator and weight changes did. It was way more work, and I had to re-jet to make it all work right. In that case the exhaust was an ebay special, it looked nice, it's loud to the point of being annoying and I just didn't see the gains I'd expect. That one is my buddies bike, he likes it, so it's all good. I just prefer a nice quiet bike.... I know, loud pipes save lives... but dang... I don't wanna scare small children riding something that sounds like a Briggs and Stratton on crack. I've never really liked the sound of a loud thumper anyway...

Oh yeas CVT tuning does wonders . I replaced the 8g rollers with 5gs on my 4T scoot and WOW it was faster .
When I put in sliders my takeoff was a hair less but it had a better and more steady power curve . I hated the noise of roller rattle and sliders are much more quieter and last longer . I will weigh mine to see how much they have worn since takeoff is even faster but I top at 67 to 70 instead of 75 and RPMs are higher at 60 MPH according to my ears . Mt scoot redlines at 8,500 or at least that what the HP is rated at .
I have 8g DR Pulley sliders in my hot rod 2T and I can still hit 9k RPMs up a hill with a running start so I will need to get a taller gear

The sliders remain longer in high gear when letting go of the throttle, compared to the rollers, which go into low gear, and cause a lot of engine braking.
Sliders ride more economical.
Have fun riding!
