This 1967 Triumph Tiger Cub, also known as the Mountain Cub was customized and restored in 2023. A complete rebuild of the engine, forks, and wheels with custom fenders, tail light, and seat brought what was a tired barn find back to life.
Painted in the original “Grenadier red” and white, the bike, also referred to as the “Baby Bonneville,” was an instant hit when it came out. The Mountain Cub was an America-only model, with full size front forks and other features that made it perfe
Replacement items on the build include a new reproduction exhaust system, new Girling shrouded shocks, stainless steel wheel rims and spokes, gear shift lever, and a set of handlebars. All cables and rubber parts were also replaced. A new Lucas ign
One of the goals on the modifications was to level out the stance of the bike. The rear shocks are about a half-inch longer than the ones that came on the bike. The seat was also raised slightly to improve the position for off-road riding, and was s
While there were some customizations elsewhere, the forks were restored to stock form, with new fork tubes, seals, sliders, and nuts. All hardware was re-plated with the original cadmium.
The tank is the jewel of this Edward Turner design. It is scaled down, but still retains some of the flavor of the Bonneville tanks. An interesting feature of this tank was the solid steel beams that pass through the tank, front to back, and make th
The wide “Western style” bars were shortened by an inch on each side, but still give them enough spread to make off-road riding better. The original handlebar switches were cleaned and restored, and wires were concealed inside the handlebars. The or

The aluminum fenders were made shorter than the originals. A flat-top rear fender from an aftermarket supplier was re-formed to give it a higher crown, and the turned up edge on the end. The front fender was hand formed out of .090 sheet. The origin

The tail light was made from a damaged bronze cymbal and a brass plumbing fixture turned down on the lathe. The lens came from a Stanley tail-light lens made to go on a Honda minibike. The design is my interpretation of the Sparko “limp dick” model
Shortening the seat exposed the rear frame loop and fender, and the tail light was used at the transition, crossing over the frame loop.
The before pictures. Besides being a tired-out bike, there were customizations like relocation of the horn and speedo, some new bars, and an alloy wheel rim on the front end, with spoke nipples floating around in their over-sized holes.
The fenders that came on the bike seemed oversized, and did not fit well, especially on the front. I suspect they were not the originals. A previous owner had modified the exhaust with a section of flex tube welded in the header pipe, and a paint jo
Other than some interesting cracking designs in the vinyl, the seat was trash, save the pan. Only the original color scheme was used in the making of the custom seat.
The first picture I was shown of this bike. It had been part of an estate, sold to me by the daughter of the previous owner. One of her goals selling it was to find someone who would do more than just flip it, but get it running again, and maybe eve
