Performance parts for 49cc, 50cc, 90cc, 125cc, 150cc, and 250cc 2-stroke and 4-stroke Full-Size Street Scooters.
*Note: One way to start performance upgrades is by changing the Variator Roller Weights. By doing so you can change the variable High or Low speed of your engine. 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. |
