This high-quality performance package can gain your ultra lightweight bike up to 14* horsepower over stock! Be the fastest in your grid with better acceleration, more torque, and higher top speeds!

*All motorcycles perform differently, this was the performance gain our 2018 Ninja400 model had during testing performed in San Diego, CA 75° weather, SAE corrected. We expect your Ninja 400 to have similar results if it’s well maintained and not built at the factory on a Friday at 4pm or Monday 5am after a World Cup match.
