THUMPSTAR - HUNGE 140CC

Wheels

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 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.

Suspension

VS1 Front Forks

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.

Header

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.

Footpegs

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.

Engine

YX Electric start

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.

Airbox

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.

Waterproof Electronics

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.

Rear Axle

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, we made it a Lockheed design so only one 30mm spanner is needed for removal.
