1972 Yamaha YZ635 250cc & 1989 Yamaha OW01 750cc
1972 Arwidson Yamaha YZ635, raced by Pentti Korhonen during the Yamaha Classic Racing Team (YCRT) Demo. The bike in the back is a 1989 Yamaha OW01 raced by Mario van Rooijen.
For the 1972 season Yamaha introduced a brand new production racer: the TD3. It was an aircooled 250 twin based on the new RD250 street bike, with bore and stroke at 54×54. Yamaha Motor NV established a “Factory Team” for the 125-250-350 classes. For the 250cc Yamaha Japan had developed a water-cooled version of the TD3. Two machines were send over one for Rod Gould (Hostettler Yamaha) and one for Barry Sheene (Sonauto Yamaha). After the Austrian GP the machine of Barry Sheene went to Jarno Saarinen (Arwidson Yamaha). Jarno won the 1972 Worldchampionship on the YZ635. The YZ635 had watercooling, special crankshaft, complete magnesium drum brakes, aluminum rear shocks, an aluminum rear brakepedal, nylon chokelever, slightly different magnesium waterpump (compared to the waterpump on the TZ350 of 1972), aluminum steering damper, and the riders had different gearbox ratios to choose from. This YCRT YZ635 replica is built with several factory parts, other parts were made in accordance to the factory specifications.
