CURRENTLY IN RESEARCH AND DEVELOPMENT
Bring back the 2-strokes! For the past year, we have been conducting research and development of one of our most exciting projects yet! The Thumpstar MX line of bikes. Looking forward to 2020 will be releasing our first race ready line of 50cc two strokes which will stack up and compete, without the worry of a heavy price tag when your jr racers are just starting out. Our design and development team has put together the ultimate 2-stroke 50cc package which efficiently delivers sufficient power to compete with the other race ready bikes in the mini class. At the heart of the bike sits a 49 cc, 1-cylinder, 2-stroke, water-cooled engine with reed intake that produces impressive power out of the box. The centrifugal automatic clutch provides manageable acceleration and makes learning to ride a breeze.

 


Fastace Adjustable forks with Progressive Springs
Top of the line Fastace 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.
High Volume Alloy radiators
The MX50 is equipped with 100% aluminum construction that provides increased heat and pressure tolerance, improved heat dissipation, increased durability, and improved cooling efficiency. Made with aircraft quality brazed aluminum and are precision TIG welded for extreme durability.
7075 Rims w/ Stainless Spokes
Henly designed 10/12” wheels with anodized red hubs mean that the bike is not only a killer with looks, but also provide extreme durability. The rims are made of 7075 series alloy and are used by almost all top riders. Henly rims keep on being the best, strongest and most reliable rim we can provide. Stainless steel spokes prevent stretching and snapping which is a common issue with other types of steel spokes.
CNC Hub
The Henly CNC hubs are made from 1 piece billet alloy on precision CNC machines, and are anodized to provide wear resistance and provide you with a heavy duty package which will stand against the test of time.
1 1/8 Fat Bars 
The design of the MX Steeze handlebar is aimed at reducing weight whilst maintaining high strength. Strength for the bar is created within the tapered wall profile allowing for a braceless design. This enables a confident level of flexibility in the handlebar. Millions of tiny steel shots are blasted at high velocity at the bar, breaking the surface tension of the material and leaving a textured surface finish which increases the fatigue life and durability of the bar.
- HSK Racing Front Brake
More important than engine power and acceleration, is stopping power. The MX50 is well equipped with Dual-Pot HSK brakes in the front, and Single-Pot HSK brakes in the rear. HSK provides an extremely responsive package that will allow any rider precise control into every corner.
