Thumpstar - TSX 125cc GR Dirt Bike

Frame

Thumpstar Quad Bar Chassis

With developments in chassis strengthening and design, Thumpstar's new Quad 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.

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

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.

Header and Exhaust

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.

Linkage

Swingarm and Linkage developments

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.

Engine

YX-R 125 Engine

Giving you the thump you need to get off the line and the punch that gets you out of the gate, the YX-R125 engine delivers a whopping 11+ HP at the crank. Precision engineering from Yin Xiang delivers a reliable and strong engine package that consistently gets the job done.

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.

Waterproof Switch

Designed to withstand the elements, our switch ensures reliable performance even in rain or mud. It's the perfect accessory for off-road adventures.

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, made it a Lockheed design so only need one 30mm spanner for removal.

Rear Shock

Boost your ride with enhanced stability and control. Crafted for off-road enthusiasts, our rear shock absorbs bumps and vibrations for a smoother ride.

3-Bolt Chain Guide

Guards

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.
