(So much for progress.) everything was present and correct on this bike, an unrestored and very clean machine that had covered less than 40,000 km since new. apart from a pair of honda mirrors, the only non-standard part was the fuel-tank which, the bike’s owner said, was from the near-identical rd250 (the original was damaged in a crash) and had a slightly different speed-block pattern. Sitting on the Yamaha rapidly reminded me why I’d fitted my own rd with aftermarket low “ace” bars and rear-set foot-rests, because for such a sporty bike the standard riding position is very sedate. the high handlebars sit you bolt upright in the seat and the footrests are set well forward. (Predictably, this bike’s foot-rest rubbers showed the signs of contact with the road.) everything else was just as I remembered it, though, and the Yamaha certainly got the memories flooding back as I pulled away.
