Supercharged Brit breaks cover

Reborn British brand Hesketh launched a new bike at the Carlole Nash MCN London Show last weekend – and it’s a 2100cc monster!

Named the Valiant after the cold war bomber, the bike is based around an absolutely enormous supercharged v-twin, which pushes out a massive 217ftlb of torque with 210bhp on tap – and that figure is just the start. Hesketh are hoping that this could be somewhere nearer 250bhp when the bike is tested later this year.


The supercharger has been supplied by Rotrex and was developed for the engine in collaboration with forced induction specialists TTS Performance. Hesketh’s Paul Sleeman said: “The supercharger idea was just case of why not? Let’s push things a little harder and see how compact we can get things in and around the twin.” 

The British marque also wanted to keep things decidedly British everywhere else they possibly could too, with most of the engineering and parts made and developed by UK based manufacturers wherever possible.

Suspension has been taken care of by K-tech and features the firm’s Razor rear shock while responsibility for stopping this absolute monster has been handed to Pretech with a set of billet 12-piston calipers up front and a Beringer four-potter on the rear.

Keeping the British theme going is the addition of a Smiths speedometer, while the frame and swingarm are produced by Nottingham’s GIA engineering and the billet machined items on the motorcycle have been taken care of by Billet World in Derby and include the primary drive, rocker covers and yokes. 

The Valiant is also the first Hesketh motorcycle to feature the company’s large H logo, which belongs to their engineering and development department and which also won’t be available on production machines. Sleeman further commented: “If you see it you will know that it was made by three old farts in a shed near Gatwick.”

The Hesketh Valiant Supercharged will be available in summer 2018 and will be marketed at a slightly eye-watering £50,000.
