I picked up a rear wheel for the Benelli/ATC250R hybrid. It’s from a Yamaha YM2C Big Bear 305 scrambler, but the same wheel and brake was common to a lot of ’60s and ’70s twins, including the R5 and RD250. It is similar in size and appearance to the Bridgestone 175/200 wheel I have for the front, but unlike the Bridgestone’s rear wheel, this one has the drive sprocket on the left to match the ATC250R engine.
