Description
The Ninja400R Race Spec Shift Star is machined from an OEM shift star with a more aggressive profile and sharper gear points to give more concise shifts and reduce or eliminate the annoying false neutrals than can easily happen between gears with the OEM shift star. We recommend using our Heavy Detent Spring with this shift star for the best results.

The Norton Race Spec Shift Star is a game-changer. By reducing shift throw, it delivers shorter, faster, and more precise gear changes. I’ve had this upgrade installed on both my previous Ninja 400 and my current ZX-4RR, and the transformation is undeniable. What was once a mediocre gearbox now shifts with the crisp precision you’d expect from a full-fledged ZX machine. Outstanding work, Norton!
