Thumpstar - TSK 90cc Dirt Bike

Our baseline models have provided our customers with an exceptional package for an affordable price. The TSK90 is nothing short of that. By making changes which increase the strength of our baseline models we think we have set the standard for the pitbike industry.

The TSK90 has received our signature stealth plastics which give it a sleek look, and makes it clearly distinguishable from knock off brands. The frame has been redesigned, it is now a wrap around frame which provides a much stronger package, and accommodates a stronger swing arm. 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. Waterproof Wiring

Building a bike that will last has been a main focus of ours since the beginning. We have given the TSK90 the same waterproof wiring system as its bigger brothers the TSX125 and TSX140. This will stand the test of time and exposure to the elements.

Stator Guard

Rider protection is a feature that we take seriously when producing any bike. With this in mind we have redesigned our stator guard firstly to protect the rider from any sort of chain grab around the foot, but also to protect the engine from damage. New Plastics Stripe Seat

The TSK90 has had a bit of revamp on many levels. Since our mid and full size bikes were getting new skins, the TSK90 hasn'tn't been left out. It has received the full stealth plastics kit accompanied by our new gripper striped seat, giving a sleek and stealthy new look. Molkt carb

Reliability comes with using trusted brands of parts. The TSK90 now includes a Molkt 19 carburetor which allows us to say that the performance and reliability of these bikes has been greatly improved on previous models. Brands
