1970 is considered a pivotal year for Triumph motorcycle design. It was the last year of what many considered some of greatest motorcycles ever made. Although it lies in the shadow if its big sister, the Bonneville, the 1970 TR6 is probably one of the most rider-friendly and versatile Triumphs made in the modern era.
In 1970, Triumph offered two variants of the TR6 – the C model, primarily intended for dual purpose riding – and the R model for everyday street and touring use. The 1970 650 single carburetor twins reached the zenith of pre-oil-in-frame development with features such as a progressive and powerful dual leading shoe front brake, light throttle operation and a change to an American SAE thread form on all fasteners. This change alone greatly assisted dealers and owners alike in servicing the motorcycle. Other changes specific to this year include a revised rear passenger grab rail, and a significantly improved engine breathing system. 1970 was the only year to incorporate a pair of removable front engine mounting plates that made engine removal and installation an easy task.
The 1970 Triumph 650cc TR6R Tiger on offer here was subject to a ground-up restoration in 2019 to concours standards. With period-correct paint and finishes, the bike presents in beautiful condition throughout. A substantial file of restoration receipts, many from marque experts, Baxter Cycles in Marne, Iowa, show the extent of the refurbishment. The engine feels taut and powerful, while the bike shifts through all gears flawlessly. Brakes, suspension and all electrical systems work as they should.
By the end of the ‘60s, the larger Triumphs had arrived at what most enthusiasts agree is the models’ ultimate incarnation and today late, pre-‘oil-in-frame’ 650s such as this one are becoming increasingly sought after by collectors all over the globe.
