Triumph Glasgow create 135bhp supercharged Triumph Bobber Black

1 of 2

Fancy a Triumph Bonneville Bobber Black with the rear wheel power of a Speed Triple and more torque than a Ducati Diavel? Well Triumph Glasgow have created the bike of your dreams and it could be yours right now for £22,995.

Based on Triumph’s 1200cc, 76bhp parallel twin cylinder Bobber Black, this monster features just about every Triumph accessory in the book.


The custom satin black paintjob is by 8 Ball, the downpipes are wrapped, there are whitewall Avon Cobra tyres, a host of bespoke fabricated parts, a fully adjustable Fox shock and equipment borrowed from other bikes, including Triumph Speedmaster beach bars and a Triumph Thruxton exhaust and screen.

Not all the mods will be to everyone's taste

Fit and finish puts the standard machine in the shade, but the icing on the cake and that huge hike in performance, comes in the shape of a Rotrex supercharger, fitted by TTS Performance Parts.

Triumph Glasgow Managing Director, Martin Rees explained: “The Bobber lends itself to modifications, but we wanted to do something really crazy.

“We discussed putting a turbo or nitrous on it, but we wanted reliability so landed with this. The motor is stock.”

Its low-speed manners are impeccable 

With such an increase in power you might think it’s an animal, but its low-speed manners are impeccable and fuelling would put a Kawasaki H2 to shame. Poke it with a stick and it’s another story altogether.

A clacky exhaust note drills into your eardrums as the bike accelerates in a very un-Bobber-like way, but the power delivery is feel-good- linear. Off the throttle the supercharger hisses on the overrun.

LED lights replace the standard rear set-up

The standard chassis, gearbox, clutch and twin brake set-up all cope with the extra power while the Fox shock gives the Bobber a tougher, more composed feel. This might be a Bobber with a sky-high price, but it’s loaded with serious attitude and the performance to match.

It took a lot of work by TTS to make the Rotrex supercharger fit into the Bobber chassis but the Bobber is now delivering a fat 135bhp peak and a thumping 90ftlb all from an unmodified T120 engine.

Bespoke exhausts are designed to cope with the extra gas flow and look cool with the wrapped pipes. The rear shock has been replaced with a Fox shock from the Triumph catalogue but the forks are standard.
