1970 Triumph T120 Bonneville

The most famous of all Triumph motorcycles was the Bonneville, named after the Bonneville Salt Flats in Utah, where several motorcycle companies tried to break speed records.  Many Bonnevilles were raced with great success in production classes, particularly on the Isle of Man. The first production run began in 1959 and finished in 1983.

This fine example was first manufactured in May 1970 and exported to Triumph Corporation Baltimore on the 4^th June of that year. The machine was repatriated to the UK in 1992 by the specialist motorcycle importer Bol D’Or Motorcycles Ltd, and a restoration to British specification commenced. For many years, the Bonnie was on display in a showroom; we understand that at this time, it formed part of the Henry Pearman collection (of ‘Eagle Racing’ – the Jaguar E-Type specialists).

Recent work and upgrades at SRM Engineering include an engine rebore, together with the fitting of: new pistons at a ratio of 9:1, unleaded valve seats, Colisibro valve guides and springs, and stove-enamelled cylinder heads. Other recent replacements include the steering lock, fork gaiters, front brake shoes, a modified multi-function clutch, front hub sealed bearings and petrol ethanol – proof taps. In addition to the above, the machine has been equipped with new Amal carburettors and L.F. Harris silencers. The ignition has been upgraded to Boyer electronic for smooth running.

After lavishing much time and money on the Bonneville, the current custodian has decided to turn his attention to other ventures. The carefully used, show condition machine is offered with its V5C registration certificate, invoices and sundry paperwork.
