Description

Bring back the 2-strokes! For the past year, we have been conducting research and development of one of our most exciting projects! The Thumpstar MX line of bikes. 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.

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.

mx50jr Stainless Spoke

7075 Rims w/ Stainless Spokes

 

Henly designed 10/10” 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.

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.
