Norton Motorcycles announced a new 1200cc carbon-clad sportbike, claiming a maximum output of more than 200 hp and a dry weight of 395 pounds. The V4 RR is priced at £28,000 (US$34,777) while a special edition V4 SS version is valued at an even more posh £44,000 (US$54,651).

The engine is a 72-degree V-4 with an 82mm bore and 56.8mm stroke. Peak power arrives at 12,500 rpm while torque tops out at 95.9 lb-ft. at 10,000rpm. Speaking with Britain’s MCN, Norton designer Simon Skinner says the company initially wanted a 90-degree V configuration to avoid the need for a balancer shaft but the 72-degree angle was a better fit for the V4 RR’s chassis geometry. Skinner also says the engine is about the same size as the Aprilia’s 65-degree V-4 used on the RSV4 as well as Norton’s own Isle of Man TT racer.

The ride-by-wire throttle system allows for three engine mappings: Road, Sport and Pro-Race. The V4 RR also comes with a six-axis Inertial Measurement Unit and an electronics package including traction control, wheelie control, launch control and cruise control. The V4 RR also comes with both a slipper clutch and a quickshift system.
