Made in Metal Triton 02 December 14

The Triton is a Classic British cafe racer that uses a TRIumph engine and a NorTON frame. The usual configuration is to use a Triumph Twin engine but in this case the triple engine from a Triumph T150 was used in the build by British experts workshop “Made in Metal “in Staffordshire, England.

The bike was acquired new, beautifully-sculpted, hardanodised engine plates, an extraordinary head steady, a reworked exhaust with handmade reverse cones, one-off mudguards and a hand-crafted seat unit that hinges up to reveal a weatherproof electrics box with Molex connectors and a LiPoly battery.

Almost everything else was modified and improved. Acquired a brass eccentric and adjuster screw to allow the race carbs to tick over. It's interesting to see how fade-free the Fontana replica brake is. On the road it’s got more feel than any other drum and pretty good stopping power. The double cables operate via a Suzuki GT750J lever, which has a special pivoting arrangement for the cables to balance the forces either side.
