The SRX250 was a small Japanese-market sports single: an air-cooled, four-valve DOHC 249 cc engine with electric start and a six-speed box, in a light chassis with a 16-inch front wheel. It was the little brother of the SRX400 and SRX600 and aimed at riders wanting a sporty, cafe-flavoured lightweight.
