Small, compact, yet simple 90cc

We've listened to years of feedback on our best-selling kids' bike, and we're excited to introduce the revamped TSK90, which takes an already awesome package for junior riders to the next level.

Firstly, we've given it a fresh look with our new mini stealth plastics, making it slick and appealing to both kids and adults while matching our bike lineup. But the real magic lies under the hood. We've replaced the fully automatic engine with a new semi-automatic one, added both electric and kick start options, and boosted its power, making it suitable for heavier junior riders.

Safety is paramount for kids, so we've added an emergency lanyard to kill the engine in case of a fall. Plus, with the adjustable throttle limiter, parents have full control over the bike's speed. The TSK90 is not just a kids' bike; it's a safer, more powerful, and cooler ride for the next generation of riders.
