2023-2026 450SXF/FC/MC Second Injector Kit

(KTM 450SXF • Husqvarna FC450 • GasGas MC450F)

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.

Kit Includes:

• Vortex ECU with 10 custom JPM maps

• Brand-new OEM airbox with pre-fitted second injector kit (easy install)

• Fuel line & stepless clamps

• Vortex ECU-to-injector cable

• JPM Twin-Outlet Fuel Spout
