Segment: Enduro/Offroad
Production years: 2002, 2003
The Spanish engineers from Rieju Motors have designed the 2003 MY RR 50 SM Castrol for riders on the market for an entry-level trial bike, but with a zero-compromise performance. At its heart lies a liquid-cooled, two-stroke, 50cc, single cylinder lump paired to a six-speed manual transmission. It also comes with an upside-down telescopic fork, a rear monoshock, and a disc-based braking system.
