You can go with a Stage 1 Jet Kit to give your stock engine a 5% boost of horsepower or send it the way up to Stage 7 (available for some street bikes) if you’ve made significant upgrades to set your bike up for success on race day.

STAGE 1 DETAILS

Perfect for motorcycles with a stock engine using the stock airbox air filter and pipes. Stage 1 Jet Kits are engineered to improve throttle response and deliver approximately 5% more horsepower than stock.
