The Triumph Rocket III TFC is already a limited edition of the largest-displacement production motorcycle in the world, but this particular bike takes it to another level. It has been modified and enhanced by renowned specialist Thornton Hundred, making it a unique and beautifully finished custom bike.

The Rocket III TFC is a rare and powerful bike, with a 180bhp / 166lb-ft 2.5-litre three-cylinder motor, coupled to a six-speed transmission. The TFC model was made even more powerful and responsive through lightening the internals, incorporating titanium valves, and with a higher redline. As standard, it was equipped with electronic rider aids including lean-sensitive traction control, cornering ABS, four riding modes, plus a quickshifter and autoblipper.

The modifications by Thornton Hundred include a bespoke CAD designed subframe machined from billet aluminium, with a built-in tail light, brake light, and indicator combination. The carbon seat base with custom foam pad and a diamond-stitched Alcantara cover give it a unique look. The bike also features a custom Ohlins shock absorber integrated via a bespoke billet CNC machined titanium suspension rocker and linkage, plus a custom CNC machined billet side mount for the number plate, which is illuminated for MOT test compliance.

One of the most striking features of this Rocket III TFC is the single-sided spoke wheels with 9mm stainless spokes, with CNC machined rims and hubs, tubeless at the front and rear. Other additions include custom CAD designed footpegs, with the side stand and foot controls all CNC machined from billet aluminium.

The bike has only covered 29 miles and remains in as-new condition, with no wear or damage to the exterior trims or mechanical elements. It has been in single ownership from new and comes with a leather TFC bag, document wallet, factory TFC certificate, and handbook with original build photos from Triumph.

This Triumph Rocket III TFC by Thornton Hundred is a remarkable and unique custom bike that would be a superb addition to any assembly of two-wheeled machines, and a thrilling companion on the open road.
