The Thumpstar TSK 90cc is the perfect mid-size kids’ dirt bike, offering a balanced mix of beginner-friendly control and slightly more power for growing riders. With both electric and kick start, this semi-auto bike brings convenience and confidence to the track or backyard. 

Description

Built for young adventurers who are ready to graduate from the 70cc range, the Thumpstar TSK 90cc dirt bike provides that extra boost without overwhelming newer riders. It features a 90cc FH 4-stroke engine paired with a 4-speed semi-auto transmission (N1234), making gear shifting easy without the need for a clutch. The electric start adds simplicity, while the kick start gives a reliable backup.

Upgraded with a Pipe Bomb DW2 28mm exhaust and header bomb, it offers a throaty sound and enhanced airflow for improved performance. Its steel rims with 12″ front and 10″ rear tires provide solid grip, and the suspension system—600mm front inverted forks and 280mm rear shock—is dialed for smaller riders. A 27″ seat height fits a broad range of youth sizes, while disc brakes on both wheels ensure quick stops. It’s a smooth, stylish ride made for learning and leveling up.
