The JPM Second Injector Kit is the must-have upgrade for the KTM, Husqvarna, and GASGAS 450cc 4-stroke platforms. Delivering proven horsepower and torque gains across the full power curve, the difference is instantly noticeable from bottom-end pull to screaming top RPM. Whether you’re on a stock bike or a fully built race machine, this is the upgrade that sets you apart from your competition.
Paired with the JPM-Tuned Vortex ECU, you’ll unlock 10 exclusive JPM maps, giving you the freedom to fine-tune your setup for any track or weather condition. Adjustments are quick and easy—just a flat-head screwdriver and you’re dialed.
Unlike other injector kits that rely on fragile plastic T-pieces, JPM’s design uses a twin-outlet fuel feed for maximum durability and reliability under race conditions. Installation is simple, and the kit is fully reversible, allowing you to return your bike to stock anytime.
