Bike Of The Day: 1973 Triumph T140V Bonneville 750 Custom

Brady Young at Seaweed and Gravel in Encinitas, California, transformed a 1973 Triumph T140V Bonneville into a stripped-down cafe racer. The original Triumph tank received a metallic blue finish, and the frame underwent a black powder coating. Both front and rear fenders were removed, making way for clip-on handlebars wrapped in leather grips and a smaller amber-tinted headlight.

The frame’s tail was bobbed and fitted with Hagon adjustable shocks, along with a shortened gold chain. A “Brat” style seat was installed, relocating the license plate to the inner fender area, while a small LED tail light was attached beneath the seat frame.

The front end of the bike now boasts larger upside-down forks borrowed from a Suzuki GSXR750, featuring a single 310mm disc equipped with a 3-piston caliper. The master cylinder was sourced from a Honda XR600, and the powder-coated wheels sport Bridgestone Battlax tires.

The 750cc parallel-twin engine underwent a rebuild, and its cases were powder coated black. Modifications included Mikuni round-slide carburetors, foam Uni filters, and the addition of a Boyer electronic ignition with an Emgo coil. The T140 originally used the frame as an oil tank, and the 5-speed transmission retains its original right-side shift configuration. Completing the build, the flat track-inspired pipes are wrapped in header material and equipped with short silencers.
