The Wormburner is the original, show winning and magazine featured HUC frame.  They were designed with ease of assembly for the builder in mind and are a perfect starting point for anyone wanting to build their own bike.

Wormburners have been shown at motorcycle shows all over the the world and have won top trophy's at many rallies and events for the last 12 years so these have forged a great name for themselves and are still at the top of the pile in the Japanese motor chop scene.

Our black GSXR1100 Wormburner was featured in Back Street Heroes magazine built using this frame and other HUC parts. 

The Wormburner has now evolved to a universal chop frame to take most Japanese or British power units and running gear.
