Many of today's top supercross and freestyle riders are bolting on the FMF
Powercore 2 Shorty silencer. Its gives the bike a more immediate throttle
response and gives a harder low end hit. It's perfect for tight Supercross
tracks and/or hitting a jump right out of a corner. With less clutching and
a faster revving motor, this silencer deliveries the power when you demand
it. We also offer a Big Bore version for some of the mini's. With testing we
have found out how to get a little more power on the bigger bore super mini
bikes (100cc) with this new silencer.
