Following its successful adoption for the 1972 works twins, water cooling first appeared on Yamaha's over-the-counter racers with the introduction of the TZ range in 1973. Over the succeeding decade the TZ engine was updated with reed-valve induction, exhaust power valves, separate cylinders and a backwards-rotating crankshaft, but the layout always remained that of a parallel twin. On the chassis side, discs replaced the original drum brakes, a 'lowboy' frame was introduced and an aluminium swinging arm adopted. From the mid-1980s onwards, a succession of more radical changes would see the TZ fundamentally altered.
Offered here is an example of the new-for-1986 TZ250S, which for the first time featured Yamaha's Deltabox aluminium twin-spar frame and rising-rate rear suspension. Little had changed inside the engine apart from the switch to six-petal reed valves, up from the preceding four. Finished in classic white/ red livery, this Yamaha TZ250S was raced in events in the Far East including Malaysia, Thailand, Indonesia, and Macau (but not necessarily all of them) by Robin himself and possibly top Japanese riders whose names are not remembered. Restored by renowned specialist Nigel Everett, the machine has not run since and will require recommissioning before returning to the racetrack. There are no documents with this Lot, and no other history is known. Prospective bidders should satisfy themselves as to the motorcycle's completeness and mechanical condition prior to bidding. Sold strictly as viewed.
All lots are sold 'as is/ where is' and Bidders must satisfy themselves as to the provenance, condition, age, completeness and originality prior to bidding. Visit the Bonhams Motorcycles website for all pertinent auction information.
