1968 Yamaha DS6250 Engine Number: DS6 112240 Chassis Number: 112240 Max Power: 28hp top Speed: 140kph, the Beginning of the end with a top speed of 140kph the impact of this bike on the open road motorcycling fraternity is difficult to understate, the Ds range laid the foundation for what was to become Yamaha's infamous Rd (race-developed) series which ultimately spelt the end of British dominance, the engine has a high degree of sensitivity. A quarter-inch turn at the throttle magnifies to an intense leap at the rear wheel. Whatever you put into the bike, it tends to translate that input, amplify it and feed it back to you, the DS6 served notice in 1968 and was no place for a jerky, indecisive pilot who had been brought up on the somewhat lofty British singles of the day. It's the way the Yamaha's two-stroke engine delivers its power that separated it from the then-preferred four-stroke twins. Four-stroke twins accelerate by pulling themselves consistently through the rev-range with determination - not so with the DS6 which throws itself through its rev-range delivering instantaneous chunks of power, the revs build so rapidly that the tachometer always seems to be one shift behind. Overall, the DS6 is a rare thrill, merely for the fact that many of its type got the better of the rider. This particular example has been vetted by Hugh Anderson and is in very original condition right down to the signature original grey cabling.
