The CB250RS was a slim, light road single built around a four-valve engine developed from the XL250S trail bike, with counter-rotating balancers to quell vibration and twin exhaust ports each feeding its own silencer. Early bikes were kick-start only. Nimble handling and good economy made it a favourite with learners and dispatch riders, though it was never a long-distance tourer.
