Scooter Performance Parts

Here at PartsForScooters we carry a variety of performance parts to help unlock the true potential of your scooter.

Hoca offers big bore cylinder kits in a number of displacements, fuel system upgrades such as larger carburetors and matching performance intakes, 2 stroke expansion chamber exhausts as well as transmission tuning items such as gear sets, clutches, variators and roller weights.

Dr. Pulley has innovative transmission tuning parts such as their sliding roller weights and low slippage Hit clutch. In addition to these items they also offer standard round roller weights which utilize the same proprietary self lubricating material found in the sliding weights and a performance variator designed to give your scooter optimal gear ratios.

We also offer performance four stroke exhaust systems designed in house as a supplement to the Hoca and YMS V8 brand performance exhaust for two and four stroke engines we carry.
