Derived from the class-leading R1, the aluminium Deltabox chassis is one of the lightest, strongest and sharpest handling designs in any category. Developed to handle 200bhp, this high-tech frame uses the CP4 engine as a fully stressed member to keep weight to an absolute minimum. Equipped with a long aluminium swingarm but with a compact wheelbase of 1405mm, the Deltabox chassis delivers stable, light and agile handling in a wide variety of low and high speed conditions.
