Lighter. Faster. Better Balanced.

Give it a trial.

Challenger

This bike is the result of two years of intense research and development. Three different times we scrapped everything and started over from scratch. We didn’t want to settle for anything less than perfection. With the Challenger, we’ve created something that we’re very proud of.

Extremely
Responsive

Our dynamic motor has been re-designed for optimal power delivery and instantaneous response time. The bike is designed specifically for trial riding, whether you need a quick, short boost or a more powerful thrust to reach high speeds.

Unrivaled
Technology

Our manufacturing process incorporates modern hydroforming technology to shape the metal, resulting in a lightweight frame with ultra-strong structural integrity. 

Perfectly
Balanced

The geometrically balanced design combines a light aluminum frame with a strategically located motor and battery to create a perfect center of gravity.

Remastered
Frame

Our frame’s geometric design provides exceptional stability. The aluminum center makes the bike light and easy to maneuver while providing ideal weight distribution for optimal riding conditions.

The Challenger is unlike anything else I’ve ever ridden.
It is such a quality motorcycle and riding it was just crazy fun.
It went through the all the obstacles with ease and performed way better than I could’ve imagined.

The Challenger is an amazing trial bike.
30 years of riding trial bikes and I never rode anything so easy in all the time I’ve been riding off-road motorcycles.
