CCM's "Skunkwerx" division has built a limited-edition, flat track-inspired streetbike that is a celebration of motorcycling minimalism. The bike is powered by a 600cc, 55-horsepower single cylinder engine, which will make light work of the Spitfire's 120-kg (266-lb) dry weight.

Handmade boutique British brand CCM has been producing hand-made 450cc adventure motorcycles since 2013, honouring an off-road motorsports heritage that stretches back to the 1970s.

But in the CCM team's spare time, a few of the lads have got together to form a "Skunkwerx" division and build a "dream bike without the usual constraints of design objectives and bureaucracy" – and here's the result: the CCM Spitfire.

Due for a limited production run of just 150 numbered bikes, and set to be unveiled in the flesh at the London Motorcycle Show this weekend, the Spitfire uses a 600cc single-cylinder water-cooled engine making 55 hp and 43 ft-lb (58 Nm) of torque, for a bike that weighs only 120.8 kg (266 lb) dry.

The star attraction is a beautifully bent carbon steel trellis frame put together by Ted Unwin, who was one of the original engineers that worked on Alan Clews' race team back in the seventies – CCM stands for Clews Competition Machines.

Fully adjustable suspension is provided by Dia at the forks and Tractive at the rear, and braking is by Brembo.

With a small headlight unit, simple single seat unit and understated twin exhaust, the Spitfire cuts a very minimalistic figure, with a surprising amount of open air around the engine and a pair of barely-there mudguards that'll likely raise the eyebrows of the local road safety department.

The Spitfire looks terrific to me – lightweight, minimal and punchy. Just 150 will be sold from £7,995 (US$9,965) apiece.
