  • Forged Clamps Building a bike that lasts has been paramount to us here at Thumpstar. We have re-engineered the triple clamps on the TSC140 and produced a heavy-duty forged package that will stand up against hard knocks and bumps.
  • 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 TSC140 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. This means we have to produce a motorcycle that will stand the test of time and exposure to the elements. We have given the TSC140 the same waterproof wiring system that its bigger brothers, the TSX125 and TSX140, have.
  • Stator Guard Rider protection is a feature that we take into consideration when producing any bike. We redesigned our stator guard firstly to protect the rider from any sort of chain grab around the foot, but also to protect the engine should the chain or sprocket malfunction and let go.
  • New Plastics Stripe Seat The TSC140 has had a bit of revamp on many levels, we thought since our mid and full size bikes were getting new skins, the TSC140 shouldn't be left out. It has received the full stealth plastics kit accompanied by our new gripper striped seat, giving a sleek and stealthy new look.
  • 26mm carb Reliability comes with using trusted brands of parts. The TSC140 now includes a 26mm carburetor, which allows us to faithfully say that the performance and reliability of these bikes have been greatly improved on from previous models.
