276 SUZUKI TR250 REPLICA RACING MOTORCYCLE Frame no. not numbered Engine no. to be advised This replica of Suzuki’s TR250 racer has been built around a frame taken from a small batch made circa 2000 by Tony Baker, who is bestknown for building racing sidecar chassis. The frame is made from high quality cold-drawn steel tubing (not high-tensile) and is bronze welded. There are a few subtle differences from standard Suzuki frames, the main one being the headstock angle, while there are also rubber engine mountings. The swinging arm is longer than standard and is TIG welded. The front brake is a Fahron 8” unit, while the forks are Ceriani fitted with Maxton cartridges. The rear suspension uses Falcon alloy units fitted with titanium springs. The engine has been built around very good T20 roadster crankcases, on which sit replica TR250 cylinder barrels with seven-port cast-iron liners tuned for a wide power band (with the IoM Classic Manx in mind). The crankshaft is modified with four main bearings and labyrinth seal, while the con-rods are Yamaha (with TZ bigends) and the pistons Honda. New Mikuni carburettors are modified for increased airflow. Bought second-hand, the expansion chambers were made by specialist Peter Green. The transmission features straight-cut primary gears; a clutch drum made from aircraft-grade aluminium alloy; and a close-ratio gear set with higher 1st and lower top gears. Further details are available on request. The machine has not been used since completion. A quantity of useful spares is included in the sale. £4,000 - 6,000 €4,400 - 6,600
277 N 1969 YAMAHA 125CC YAS1 RACING MOTORCYCLE Frame no. to be advised Engine no. to be advised Diversifying from its traditional role as a manufacturer of high quality musical instruments, Yamaha introduced its first motorcycle in 1955. This was the YA1, a 123cc single-cylinder two-stroke strongly influenced (like BSA’s Bantam) by the pre-war DKW RT125. The foundations of Yamaha’s sporting tradition were soon established when YA1s won the prestigious races at Mt Fuji and Asama that same year. Yamaha’s first twin-cylinder model in the 125cc category arrived in 1969 in the form of the YAS1 sports roadster, a development of the 100cc YL1. With 15bhp on tap, the five-speed YAS1 was as fast as many British 250s, and owners were soon exploiting its potential for racing. In the UK, a Terry Beckett-tuned example ridden by Austin Hockley won 17 races in 1969. The factory soon offered a race kit, which consisted of alloy cylinders, different heads, larger carburettors, expansion chamber exhausts, a stronger clutch, and alternative gear ratios. In this form the YAS1 produced a race-winning 23bhp.The vendor advises us that this machine is believed to incorporate the factory race kit, although we have not been able to verify this. Prospective purchasers should satisfy themselves with regard to this motorcycle’s specification prior to bidding. £4,200 - 4,800 €4,600 - 5,300
