TRIUMPH T100 SPRINT BIKE

One of the UK’s top custom and vintage motorcycle builders is The Baron’s Speed Shop, based in South London. They’re famous for their meticulous work on old British iron, both unit and pre-unit—plus the occasional custom build for personalities such as Ewan McGregor and Charley Boorman.

This 1953 Triumph T100, however, is extra special. “The inspiration came from Bobby Sirkegian’s ‘Pretty Boy’ Triumph,” says Baron’s Dick Smith. “The bike is designed to compete in the Vintage Motorcycle Club’s sprint events held around the country.”

Baron’s started by working on the rigid frame, a factory item but with the lower rails stretched out a couple of inches. The motor has been very heavily reworked, with a lightened and balanced crank, billet conrods and 9:1 pistons. It’s also sporting lightened timing gear and the ubiquitous race-spec Triumph E3134 ‘Q’ cams. The magneto is an authentic Lucas racing component.

Fuel is fed by twin Amal Monobloc carburetors, with rubber-mounted remote float bowls. Spent gases exit via race headers mated to factory 3” megaphones. An uprated clutch handles the extra power, and being a sprint bike, it’s fitted with a close-ratio gearbox. A vintage Smiths chronometric tach monitors revs up to 10,000 rpm.

Rims are valanced Akronts, 21” at the front and 18” at the rear. The hefty Racemaster slick comes from M&H Tires, the company that “Wrote The Book On Traction.” Other neat touches are a modified Wassell aluminum rear fender, a custom fabricated catch tank and braided lines throughout. The peanut tank from Lowbrow Customs is one of the few ‘modern’ pieces, but fits the bill perfectly.

If you’re in the UK, keep an eye out for this machine at upcoming sprint races. The rest of you will have to content yourselves with the other fine builds on The Baron’s Speed Shop website andFacebook page.
