Triumph is one of the most iconic and revered names in the history of motorcycling. Established in Coventry in 1885, by the start of the 1900s the company had made its first motorcycle beginning a continuous run of production under various ownership until its eventual closure in 1983 before its rebirth in the early 1990s. In 1937 the Edward Turner-designed Speed Twin was released launching a range of Triumph twins that went on to epitomize British motorcycles in the post-war years. Many believe the T120 Bonneville, first seen in late 1958, to be the ultimate version of the classic British vertical twin and the last of the pre 'oil in frame' models represents the peak of development of Triumphs most iconic model.

This beautifully presented matching numbers T120R has been authentically restored to a very high standard by the vendor, a retired engineer. Keeping as much originality as possible, the wheels have been restored with Elite triple chrome rims, stainless spokes and brass nipples at a cost of £505, shod with period correct TT100 tyres. The paintwork has been refinished by Steve Beckett costing £450, all the black metalwork blasted and powder coated by Elite Engineering at £617 and the seat restored by RK Leighton at £210. The engine has had a top end overhaul by Venture Classics, including new rings and valve guides, then fitted with an LP Williams 7 plate clutch. Stainless steel nuts and bolts in the correct Whitworth and UNC sizes have been used throughout the reassembly. Attention to detail has even included bushing the rear brake lever pivot to take out any free play. This excellent Bonnie will be supplied with a genuine Triumph workshop manual and numerous receipts documenting its restoration, together with a current V5C.
