Take your performance to new heights with a Jet Kit for your motorcycle. Increase power and improve performance throughout the entire RPM range, while improving throttle response and smoothness. These Jet Kits take the guesswork out of tuning your bike.

Whether you’re rolling with a stock bike or you’ve made some modifications, our Jet Kit will optimize your air/fuel ratio to eliminate rough spots and help you take control of your motorcycle’s power. 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.

Made for the speedway, not the highway. If your bike is set up for racing, reach your maximum potential with a Stage 7 Jet Kit. Stage 7 kits are designed to optimize performance for your tuning specification or racing conditions.
