  • 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.
  • 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.
  • 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.

    Product Description

    The Thumpstar TSK 90cc is a revolutionary mini bike designed to be the perfect first ride for junior riders. Compact, lightweight, and packed with advanced features, this bike combines safety, power, and durability to create an unforgettable riding experience for kids and peace of mind for parents. Whether your child is just starting out or already has a passion for riding, the TSK 90cc is engineered to grow with them, offering a blend of performance and safety that sets it apart from the competition.

    Design and Aesthetics:

    The TSK 90cc boasts a sleek, modern design with mini stealth plastics that give it a fresh, aggressive look. This design not only makes the bike visually appealing to both kids and adults but also ensures it aligns seamlessly with Thumpstar’s broader lineup of high-performance bikes. The compact frame and ergonomic build make it easy for young riders to handle, while the bold styling ensures it stands out on any track or trail.

    Engine and Performance:

    At the heart of the TSK 90cc is a 90cc 4-stroke engine that delivers reliable power and smooth performance. Unlike traditional fully automatic engines, the TSK 90cc features a semi-automatic gearbox (N1234), giving young riders a more engaging and educational riding experience. The bike is equipped with both electric and kick start options, making it easy to get going in any situation.

    Safety is a top priority for Thumpstar, and the TSK 90cc is packed with features to keep young riders protected. The emergency lanyard kill switch is a standout feature, instantly shutting off the engine if the rider falls off. Additionally, the adjustable throttle limiter allows parents to control the bike’s speed, ensuring a safe and gradual learning curve for beginners.

    Durability and Build Quality:

    The TSK 90cc is built to last, with a wrap-around frame that provides superior strength and stability. Unlike traditional CRF50-style frames, this innovative design reduces stress on the bearings and enhances overall durability. The bike also features waterproof wiring, ensuring it can withstand exposure to the elements and maintain peak performance over time.

    Suspension and Brakes:

    For a smooth and controlled ride, the TSK 90cc is equipped with inverted front suspension (600mm non-adjustable) and rear suspension (280mm non-adjustable). The oversized front and rear disc brakes provide exceptional stopping power, giving riders the confidence to tackle any terrain.

    Additional Features:

    • Pipe Bomb Muffler: Designed to keep noise levels low while maintaining optimal airflow, this muffler is perfect for backyard or park riding.

    • Steel Rims: The 1.40-12 front and 1.85-10 rear steel rims offer durability and stability on various surfaces.
