Description

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.

 

TSK90 Kill Switch and Lanyard

Kill Switch and Lanyard

 

Safety is an important feature for kids just starting out and parents who are supervising. The TSK90 comes equipped with an emergency lanyard which can be attached to your child's wrist and will instantly kill the bike should they come off.

Adjustable throttle

 

Parental control is a must on any motor bike where a child is just starting out and learning how to ride. We here at Thumpstar have tailored the TSK 90 to those junior riders who are learning, and given you the parent or teacher full control over your child's bike, with an easily adjustable throttle limiter, the speed and power delivery of the bike can be easily limited.

TSK90 Waterproof Wiring

Waterproof Wiring

 

Building a bike that will last has been a main focus of ours since the beginning. This means we have to produce a motorcycle that will stand the test of time and exposure to the elements. We have given the TSK 90 the same waterproof wiring system that its bigger brothers, the TSX125 and TSX140, have.

 

Wrap Around Frame 

Traditional mini bikes produced by our competitors have a CRF50 style frame. We went back to the drawing board and applied our knowledge from larger, heavier duty bikes. The new TSK90 frame is what we call a wrap-around frame where the swing arm sits between it and the engine, which reduces stress on the bearings and gives the overall system better strength.

TSK90 Disc Brakes

Something more important than the power to go fast is stopping power. The TSK90 is well suited for this. With oversized front and rear disc brakes, it has more than enough stopping power to go from fast to stop in the blink of an eye.

Pipe Bomb Muffler

 

On a bike where the ideal places to ride are often backyards or parks where your child is learning, noise can often be an issue. Our pipe bomb muffler system keeps an optimal airflow while keeping the bike quiet and discreet.
