2024 Thumpstar TSR 140-C

The TSR140 has received a complete overhaul for Version 5. Gone are the days of facing struggles of dealing with issues which are common on many other minibikes. We have gone back to the drawing board and scratch built a New Frame, Airbox, Linkage Suspension, Hubs and Rims, and much more. This has not only allowed our bikes to become stronger and more reliable, but also gives the rider peace of mind knowing, no detail has been left untouched.

Our design team has produced a piece of engineering art. The frames are a new Quad Bar, which has made them stronger than ever. Along with the frame developments, we made space and rigged them with mounts to accommodate our new caged airboxes. This allows a better air filtration system while increasing airflow into the carburetor, and in turn, more horsepower. A first on pit bikes and minibikes alike, we have scaled down the linkage from the likes of a full-size race bike and fitted it to these smaller sized 110s. The linkage provides a much smoother ride than traditional PDS style suspension, which allows for faster cornering, high and low-speed adjustments, and increased rider comfort. We have redesigned our hubs and created space for a much heavier duty 20mm rear axle, coupled with stainless spokes and alloy rims, which provide our strongest wheels to date. Check out our description video and the following spec lists to see these upgrades!

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.

• 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.

• Swingarm and Linkage developments

The new 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.
