Jeremy Toye Is Building Ninja 400 Racebikes, And You Can Buy One

We take a spin on Ashton Yates’ MotoAmerica Junior Cup racebike

If you're considering building your own small-bore track bike, good for you. It's a worthy endeavor, but it'll take a lot more time than you think and you're bound to hit some frustrating, sometimes costly snags. I'm speaking from experience here. So when someone with as much racetrack and workshop cred as Jeremy Toye decides to develop and sell track-ready Kawasaki Ninja 400s, it's worth checking out.

“I’ve always raced big bikes,” says Toye, whose literbike achievements include numerous Superbike wins at the club level in America, first place at Pikes Peak, and finishes at the Isle of Man, “but when I took a Ninja 400 out at a trackday, I just couldn’t stop smiling. It’s just so much fun!”

Now you can get right to cramping your own face muscles with one of Toye's track-ready Ninjas. He's building them to three spec levels, starting at $8,900 for his "Novice Club Racer" build and topping out at $12,800 for the MotoAmerica-spec bike shown here. All the bikes come with upgraded suspension that Toye has fine-tuned, pre-installed race bodywork, and loads of other performance features that Toye selected based on his own testing and feedback from MotoAmerica Junior Cup racer Ashton Yates, whose bike we got to ride at Laguna Seca.

The video above outlines the steps Toye has taken to build a bike capable of running at the very front of the Junior Cup pack. Having a pro like Toye do the wrench-turning has certainly helped Ashton's race efforts (he snagged pole position and led every lap of the Junior Cup race at Laguna until he crashed out), and now it can help anyone else interested in getting out on the track on a kickass bike, without the headaches of building it themselves.
