This Supercharged 200HP Triumph Is The World’s Fastest Bonneville Bobber

Based in Milton Keynes, Thornton Hundred Motorcycles is a custom bike building outfit headed up by Jody Millhouse. Over the shop’s few short years in operation, Thornton Hundred has carved out an impressive name for itself, largely on the strength of its performance-focused upgrades and factory-grade fit and finish. For his latest project, Millhouse has taken his MO to the extreme, transforming a stock 1,200cc Triumph into what Thornton Hundred has dubbed the “WFB” — or “World’s Fastest Bobber.”

Starting with a Bonneville Bobber, Millhouse has treated the parallel-twin to a Rotrex C15 supercharger, TTS machine cases, forged pistons, and dry NOS injection. The Bonnie Bobber’s 1.2L twin now generates over 200hp which allows for 10.49 second standing quarter-mile runs at 130mph speeds (and that’s without using NOS). When using nitrous the machine is expected to clock speeds of around 170mph. Helping to keep the build’s 200 horses in check is upgraded suspension front and aft including an Ohlins fork, up-specced Brembo brakes, and spoked Excel rims shod in beefier and stickier sport rubber. Exhaling via a custom exhaust system, this forced induction Bobber also wears a vibrant bespoke livery courtesy of UK paint specialist Image Design Custom.

Jodie also recently took the WFB to the Goodwood Festival of Speed where he raced it up the hill — an experience captured in a Youtube video also posted below.
