This Supercharged Bobber Is As Powerful As The Yamaha YZF-R1

A quaint neighborhood in the United Kingdom has spawned one of the fastest bobbers in the world. Thornton Hundred Motorcycles is known to build some exotic and radical bobbers and scramblers and their latest build is a Triumph Bonneville Bobber that belts out 200PS!

So how did anyone manage to transform a 78PS motorcycle into something this ridiculously fast? Not only did the creators plonk in a Rotrex C15 supercharger, they also added dry NOS (Nitrous Oxide) injection. The bike pushes over 167PS at the wheel and with the nitrous boost, the figure goes over 200PS, which is as powerful as the 2021 Kawasaki Ninja ZX-10R.

For the engine to sustain such pressure, Thornton built TTS machined engine cases, forged pistons, a custom cam and an updated clutch assembly. Changes have been made to the electronics as well to handle all the extra performance. The bike seems to have a larger TFT instrument console too.

The Thornton Hundred-built Triumph Bonneville Bobber gets the custom house’s wide wheel conversion kit. This includes a new set of rims, billet machine mounts, custom seat and tyres. In fact, Jody Millhouse, the builder of the bike, isn't finished with the project yet. The next set of updates include Ohlins suspension and Brembo Monoblocs. Jody even intends to push it to 300PS this winter.

Wondering what it would cost to build your own superbike-shaming bobber? Given the labour and the parts involved, it will be astronomical. So much so that Thornton has maintained that it will not create another motorcycle like this, and this one shall remain with them for future development. Guess our best bet is to wait for the Kawasaki Eliminator H2 then.
