We are releasing a small batch of our 4th gen 85cc to YOU, limited numbers available.
For the past few years we have been conducting research and development of one of our most exciting projects yet! The Thumpstar MX line of bikes. This bike has been tested and raced throughout Australia over the last couple of years and it has been doing great, finishing with strong results, often podium placings in both MX and Endurance racing. We release our first race ready line of 85cc two strokes which will stack up and compete, without the worry of a heavy price tag when your jr racers are just starting out.
85cc Race Engine w/ Power Valve
Our design and development team have put together the ultimate 2-stroke 85cc engine package which delivers sufficient power and performance to compete with the other race ready bikes in the Jr 85cc class. At the heart of the bike sits a 84cc, 1-cylinder, 2-stroke, water-cooled engine with reed intake.
Keihin PWK 28 Carb
Reliability comes with using trusted brands of parts. The now includes a Keihin PWK carburetor well known to the motocross world. Keihin PWK carburetors are the dominant carbs on the factory motocross machines. Because of their great performance they come stock on a lot of the leading brand bikes. With these features you can take advantage of Keihin's superior performance to propel you to the race win.
6 Speed Gearbox w/ Hydraulic Clutch
A 6 speed gearbox paired with the hydraulic performance multi plate wet clutch provides clean and easy gear selection, manageable acceleration, and makes race starts and overall rideability a breeze.
Fully adjustable suspension
Our top of the line VS1 suspension provides a fully adjustable and responsive package which gives the rider full feel and control of the bike through ruts, over bumps, up takeoffs, and down landings.
7075 Rims w/ Stainless Steel Spokes
The rims are made of 7075 series alloy and are used by almost all top riders. The AK7 rim keeps on being the best, strongest and most reliable rim we produce. Stainless steel spokes prevent stretching and snapping which is a common issue with other types of steel spokes.
Pipe Bomb Exhaust
What is a two stroke without that scream when on the pipe that we all know and love? Our tuned expansion chamber and muffler package provides that crisp sound, with tuned performance.
