Note on warranty: Installation of the alpha Stage 4 Race Engine renders the motorcycle a high-performance product with a correspondingly short life expectancy on account of its use in motorcycle racing. Consequently, the machine no longer corresponds to the life-expectancy requirements of a road-legal motorcycle. In turn, this means that the warranty is restricted to freedom from defects in the materials.

Additional information
