Thornton Hundred Motorcycles is described as a bespoke Triumph builder based in Castlethorpe, Milton Keynes, founded by Jody Millhouse. Its commissions are presented as one-off projects shaped with customer input, while its standout Twisted exhaust routes both pipes to one side and joins them in a hand-finished design. The details and prices below come from Robin Nooy’s Monochrome Watches feature, published 6 January 2024; they are historical reporting, not confirmation of current operations or quotes.
Who is Thornton Hundred?
Robin Nooy’s 6 January 2024 feature in Monochrome Watches places Thornton Hundred in Castlethorpe, Milton Keynes, UK, and identifies Jody Millhouse as its founder. The name combines Thornton, the village where Millhouse grew up, with “Hundred,” a reference to the 100 mph “ton” associated with Ton-up Boys and cafe racers.

The feature traces the business from Millhouse modifying motorcycles as an early sideline in a shed to a company building bespoke machines. It reports that Thornton Hundred had completed a little over 150 custom bikes by the time the article appeared. That is the feature’s figure for 2024, not a current production total.
How the custom builds are described
Thornton Hundred works with Triumph motorcycles, according to the feature. Millhouse is described as involved in each build and in the parts the company designs. Customers take part in choosing options, and each commission is presented as an individual project involving in-house engineering, assembly and detailing.
#1 Best Overall
Components named in the article include carbon-fibre wheels described as bespoke to Thornton Hundred, high-performance brakes, engine modifications and hand-welded exhausts. These are descriptions of the builder’s work, not independent evidence that its motorcycles are faster, safer or better engineered than production Triumphs.
The Twisted exhaust: the clearest signature detail
The Twisted exhaust is described as routing both pipes to the right side of the engine, where they twist together. The feature says each section is welded and finished by hand, and that the system is made to order. Its unusual pipe layout is the most specific design detail in the account; the article does not supply comparative performance measurements.
Thornton Hundred is also reported to offer engineered parts and kits for owners who want to convert their own Triumphs. The feature gives no model-by-model fitment list, so a buyer should confirm compatibility for the exact motorcycle before ordering rather than assume a kit or exhaust fits every Triumph.

Nooy’s feature gives approximate historical figures, not current quotations. It reports around £30,000 for a fully bespoke build, with the final amount depending on selected options, and a little under £2,500 for a Twisted exhaust set. Because the exhaust is made to order and no current price list is confirmed here, treat both figures as context from January 2024 rather than prices available today.
The feature also recounts an early Ducati purchase and resale: around £7,000 to buy and £25,000 after repair. It is an anecdote in the article, not an audited transaction or evidence that restoration typically produces that return. Likewise, the article mentions supercharger and nitrous options without stating their surcharges.

The choice is between a highly personalized commission and taking on more of the conversion yourself. The feature does not provide comparable quotes or enough fitment information to calculate which route costs less for a particular motorcycle.

What the feature leaves uncertain
The Monochrome Watches article is a useful account of the company’s approach and distinctive exhaust, but it is a single magazine feature rather than a current catalogue or independently verified company record. It does not establish Thornton Hundred’s present operating status, today’s pricing, current stock, fitment by model, or the availability of particular options. For any purchase or commission, confirm those details directly with the business.
