a few ???'s about replacement belt & rollers for the cvt...

what is a good reliable belt to consider? what weight rollers are OEM for a 2013 Buddy 125? read that dropping weight of rollers by 1 gram offers a few MPH speed increase on the top end...true or trash? thanks...

Stock size is 11g, 18x14mm

Dropping down a gram will get you faster acceleration, because the engine will rev a bit higher in relation to your actual speed. But as for top end gains? Not really. That being said, going to a performance variator with a steeper ramp plate might get you some top end. Same could be said for a better exhaust, head, kit, etc etc etc.

This the belt you want. Good eBay seller. Also carries Dr. Pulley sliders:

743x20x30

I just wanted to say- the belt for my Burgman 400 cost $165. on line. OK, it's bigger than Buddy's belt, but not THAT much bigger. Sheesh.

I went with a Dr. Pulley variator and 12g sliders and was very disappointed.

I lost both acceleration and top end.

I still had very good performance with my stock rollers, but they had 13,000+ miles on them. So I figured it was time to change them. When I changed out the original rollers at 13,676 miles, 4 weighed 10 grams and 2 weighed 11 grams.

If I had to do it over again, I'd just replace the rollers with the same as stock weight or I'd try 11g sliders.

You want to order an OEM belt either through a dealer or one of the online vendors. I've seen intact Buddy belts with over 20K on them. That's what you want

My stock Bando belt blew apart at 13,676 miles.

I think the longevity of the drive train parts depends a lot on the weight of the rider, not saying anyone here is fat or anything...

I'm not very big so my weight is normal for me...

I replaced the Bando belt in my Blur after riding the snot out of it for at least ten years. It wasn't shredding yet but did have a lot of cracks so I replaced it just for peace of mind. I bought the replacement Bando from the same vendor that DeeDee mentioned. Been buying from him for years, good seller.

I bought some 14g sliders for my Blur to try out because the engine revs up really fast from a dead stop. The reason is because my engine has a +4 stroker crank along with a larger bore so it makes more torque than stock.

I use a gates pl30707. Has over 3 seasons on it. Which is a lot for me. 250lbs HA! Usually I get a smell of hot rubber to let me know the belt is slipping after a ride. The stock bando and the gates seem to last and work about the same. A new gates will reduce take off rpm until the belt beds in. Usually a 20 minute ride will have it back to normal.

Longevity depends on age and heat. Belts will heat up and age faster if you normally ride at higher speeds or do long trips.
