Overview

CR&S Duu Nottenbia

The CR&S ,

and are handsome machines and all three are powered by the same S&S ‘X-Wedge’ air-cooled OHV 1916cc American-made V-twin that produces 91bhp at 5100rpm and 148Nm of torque at 2,500-4,700rpm.

All three Duu bikes also share the same chassis – a compound structure made of one large-section stainless steel tube (which serves as the ‘backbone’ for the frame and also works, partially, as the fuel tank) and other smaller parts that are also made of stainless steel and connected to each other by light alloy components. The single-sided swingarm is also made of stainless steel tube and, according to CR&S, this chassis is built to stay free of rust and corrosion for the bike’s entire lifecycle.

The Duu trio rides on 17-inch machined-alloy wheels shod with 190/55 (rear) and 120/70 (front) tires. There’s a 48mm USD fork at the front, adjustable for rebound damping and spring preload, and a fully adjustable monoshock at the back. Twin 320mm brake discs, with radial-mount 4-piston calipers (front) and single 260mm disc with 2-piston caliper (rear) handle the braking duties and the bikes weigh about 245kg, dry. Fuel tank capacity is 15.5 Liters

and according to CR&S, the Duu is capable of hitting a top speed of more than 200km/h.
