The final phase of the Triumph twin's development began in 1972 with the first appearance of the new enlarged-to-750cc version of the Bonneville, the increase in bore size necessitating a new crankcase to accommodate the larger barrel. Other improvements included a new ten-stud cylinder head, triplex primary chain, stronger transmission and a disc front brake. A five-speed gearbox, introduced on the preceding 650 Bonneville, was standard equipment on the 750.
After the Meriden debacle, Triumph continued with the Bonneville as its main model, ringing the changes to produce a succession of special and celebratory editions, while significant technological developments included the adoption of electronic ignition and the introduction of models with electric starting and an 8-valve cylinder head. It was, of course, too little too late and the company folded in the early 1980s, its remains passing into the hands of entrepreneur John Bloor. While the Bloor-owned company developed an entirely new range of up-to-the-minute models, Les Harris was licensed to produce Triumph Bonnevilles at his factory in Newton Abbot, Devon from 1985.
The last Bonneville produced, this machine left the Newton Abbot production line on 9th March 1988 and was purchased by the late owner on 6th December 1988 for delivery on the 6th January 1989. The Triumph was purchased from Jack Lilley Ltd and comes with their invoice for £5,000 and letter confirming that this is the last Bonneville made; the machine also comes with a letter confirming same signed by Les Harris. Also included is a Certificate for Car Tax from Triumph Motorcycles dated 15th December 1988 (signed by Les Harris) and a copy of an article on Les Harris published in The Classic Motor Cycle (June 2004 edition). The last Bonneville is pictured with Les on page 66. The Bonnie also comes with six keys; its original unstamped warranty book; and an owner's handbook (1987).
This historic machine has a recorded mileage of only 16 miles and still has its original engine tag with details of the frame number, engine number, and general specification with 'RIP' under Remarks. A 'must have' for the serious Triumph collector.
