The Barry Sheene bike we have here is a square-four 1975 Suzuki RG500 XR14. Sheene won his first ever GP on it and the '76 and '77 world championships.<br /><br />In the yellow corner is an inline-four-cylinder 1980 Yamaha YZR500 OW48R, ridden by three-time world champion 'King' Kenny Roberts, complete with two reverse cylinders (hence the 'R').<br /><br />Both are excessively loud, smelly two-strokes, with wafer-thin powerbands and no interest whatsoever in suffering fools gladly.<br /><br />Get all the latest news at http://www.motorcyclenews.com
