2022 Thumpstar TSK 141E-C

Gone are the days of dealing with issues which are common on many other mini bikes. We have gone back to the drawing board and scratch built a New Frame, Airbox, Linkage Suspension, Hubs and Rims, and much more. The outcome is a much stronger, more reliable bike. Our attention to detail gives added peace.

Our design team has produced a piece of engineering art. The frame has a new Quad Bar which is stronger than ever. We added our new caged airboxes for better air filtration, increased airflow into the carburetor and in turn more horsepower. This is the first pit bike and minibike to have this advantage.

We have scaled down the linkage from the full size race bike to provide a much smoother ride than traditional PDS style suspension, allowing faster cornering, high and low speed adjustments, and increased rider comfort. We have redesigned our hubs and added a much heavier duty 20mm rear axle, coupled with stainless spokes and alloy rims. These are our strongest wheels to date.

Features may include:

• Thumpstar Tri-Bar Chassis

With developments in chassis strengthening and design, Thumpstar’s new Tri-Bar Frame allows the bike to feel more solid under foot while allowing the bike to perform with greater agility and comfort than ever before. Additions to the frame allow the header pipe to be re-routed under the frame, reducing the likeliness of pipe burns to the legs, include removable footpeg mounts, which can be easily replaced and allow the kickstand to be removed for racing, and a reinforced adjustable steering stop. The new frame is also capable of housing the new Thumpstar airbox but it is not yet a stock option.

• AK7 Wheels

We’ve redesigned and strengthened our AK7 wheels to give you the comfort of knowing buckled rims and loose spokes are a thing of the past. The cast aluminum hub has been changed to run a 6-bolt sprocket and 4-bolt disc while moving to a 20mm axle that allows for oversized wheel bearings. We’ve swapped those stretch-prone steel spokes for anti-stretch and snap-resistant stainless spokes. And lastly, the rims have been upgraded to top-of-the-line aluminum alloy.

• VS1 Front Forks

Our new line of VS1 front forks provides a plush yet stable ride through all those bumps, ruts, and jumps. Improved outers coupled with our reliable valving lets the front end have a settled movement while allowing greater front wheel feedback, keeping the fork to be rigid while handling bigger impacts.

• Pipe Bomb 2.0 head pipe

A redesigned frame came with requirements for a new exhaust header. The new Pipe Bomb 2.0 head pipe from Thumpstar allows exhaust gasses to expand, cool, and ramp back up at a higher velocity when exiting. This results in a greater bottom and low-end response while keeping the tuning in check for the top end.
