The TSK141-E has received a complete overhaul for Version 5 adding the much-awaited ELECTRIC START and compression adjustble front forks.

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. Check out our description video and the following specifications lists to see these upgrades!
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.

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 aluminium 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 aluminium alloy.
Introducing our latest VS1 front forks featuring cutting-edge TiN (Titanium Nitride) coating, delivering a smooth and stable ride over bumps, ruts, and jumps. Enhanced outer parts and reliable valving ensure stability and better feedback, even on challenging surfaces. Plus, enjoy increased rigidity for handling bigger impacts with ease.
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.
The new line of TSX bikes have received yet another significant upgrade which brings performance closer to that of full-size motorcycles, rear linkage. Rather than traditionally attaching the shock to the top of the swingarm, we have scaled and applied linkage shared with the likes of full-size race bikes to attach to the bottom of the swingarm. This improves handling in the rear and completely changes the riding experience of these bikes.
The engine provides the necessary power to accelerate swiftly off the line, delivering impressive horsepower at the crank. With precision engineering by Yin Xiang, this engine package ensures reliability and strength, consistently meeting performance demands.
One of our most exciting developments for 2020 was the design and production of our very own airboxes for the TSX and the TSB. Advances in 3D modelling and printing have allowed us to give you a system that provides much better air filtration with a dual-layer filter while increasing airflow to the engine. The airbox prevents harmful particles from entering your engine where traditional minibike foam filters would typically fail.
All of our new bikes come equipped with redesigned looms and electronics. We have done away with single flimsy wires and connectors and replaced them with heavy-duty multi-core wiring and sturdy connectors. Accompanied by water proof plugs and electronics such as the Revking CDI, Rectifier, and Coil, makes this is a far superior package to any of the competition.
Designed to withstand the elements, our switch ensures reliable performance even in rain or mud. It's the perfect accessory for off-road adventures.
We have increased our rear axle to 20mm and made it hollow, then heat treated it, which makes it a similar weight to the 15mm axle but much stronger. Finally, made it a Lockheed design so only need one 30mm spanner for removal.
Boost your ride with enhanced stability and control. Crafted for off-road enthusiasts, our rear shock absorbs bumps and vibrations for a smoother ride.
Maximize chain stability with ease. Engineered for durability and precision, our guide keeps your chain securely in place, minimizing the risk of derailment.
Stay protected and geared up with our durable guards! Upgrade your defense and ride with confidence!
Our new footpegs have been made 56mm wide, the same as aftermarket motocross 250/450 footpegs for better grip and rider comfort. We used high-quality stainless steel material for strength and to look fresh for years to come, finished off with perfectly fitting springs.
