Tank Touring 250cc Scooter Performance Roller Weights size 23x18 for 250cc water-cooled 172mm engines. Commonly found on 250cc water-cooled Chinese scooters, CFMoto V3 and V5 motorcycles and much more.


We recommend starting performance upgrades by changing the variator roller weights first.


Heavier roller weights= A slower take off speed with more acceleration and a higher top speed.

Lighter roller weights = A faster take off speed with less acceleration and lower top speed.
