Product Description
Thumpstar TSB 125E-C Mini Bike
The Thumpstar TSB 125E-C is a revolutionary mini bike designed for kids, beginner riders, and even experienced adults who crave the thrill of off-road adventures. This model combines the rugged aesthetics of full-size motocross bikes with the practicality and safety features needed for younger or less experienced riders. With its 710mm seat height, 4-speed manual gearbox, and electric/kick-start system, the TSB 125E-C is the perfect entry point into the world of dirt biking. Its Chartreuse plastics, Stripe Gripper Seat, and AK-7 Alloy Rims not only make it visually striking but also ensure durability and performance on rough terrains.
The TSB 125E-C has undergone a complete overhaul for Version 5, addressing common issues found in other minibikes. Thumpstar has re-engineered the bike from the ground up, introducing a new Quad Bar frame, caged airbox, linkage suspension system, and 20mm rear axle hubs. These upgrades make the bike stronger, more reliable, and capable of delivering a smoother, more controlled ride. Whether you're navigating tight corners, tackling jumps, or cruising through dirt trails, the TSB 125E-C is built to handle it all.

Frame
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.

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 provide a plush yet stable ride through all those bumps, ruts and jumps. Improved outers coupled with our reliable valving lets the front end to have a settled movement while allowing greater front wheel feedback, keeping the fork to be rigid while handling bigger impacts.
Header and Heaader
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
Fenghong 125cc
The Fenghong supplies a strong 4-speed 125cc engine which is similar in specification to its competitors. The motor is tried and tested and has consistently delivered a strong and reliable performance.
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
Maximize chain stability with ease. Engineered for durability and precision, our guide keeps your chain securely in place, minimizing the risk of derailment.
Guards
Stay protected and geared up with our durable guards! Upgrade your defense and ride with confidence!
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.
