market and regional exports to other South American countries but also available in Mexico and Central America. Its engine was the same 4-valve DOHC air-cooled single fitted to the CBX 250 Twister/CBF 250, but the exhaust was dimensioned to improve low-end torque with the sacrifice of 1hp resulting in a 23hp rating. XR250 (MD30) / XR250L An electric start street version of the XR250R was sold in Asia as the XR250 and Australia as the XR250L. The Honda model designator for it is MD30. It's based on the 1996-2004 model XR250R but with different suspension, fuel tank, rear subframe, electrical system, carburettor, cam shaft and most significantly the addition of electric start. There were two variants of the bike a single headlight version that looks more like the standard XR250R and a dual headlight "Baja" version. XR 350R The XR 350R was introduced for the 1983 model year and discontinued after the 1985 model year. The 1983 and 1984 models were wet sump engines with a bore and stroke of and a displacement of . The 1985 engine had a dry sump, a stroke of 63.8 mm and displacement of . The wrist pin diameter was reduced from 21 mm to 19 mm and the dual progressive carburetors of the 83-84 models were replaced by a single large carburetor. XR 400R The XR 400R was introduced in 1996. Its frame, plastics and suspension components were similar to those of the XR250R, and it had a similar air-cooled engine with RFVC cylinder head technology. The XR400R had more suspension travel and a longer wheelbase than the XR250R of the same year. Many XR400Rs were heavily modified and raced. The 400 was perhaps the most versatile of the XR line-up; many were raced in amateur motocross and enduro events. Equipped with street-legal lighting it also worked reasonably well as a dual purpose bike. It was simple, reliable and long lasting. Hard to break and easy to fix. In 2004 Honda discontinued the XR400R. XR 400M The XR 400M was introduced in 2005, and whilst having a similar engine to the XR 400R, the exhaust diameter is smaller and has a slightly lower power output. It was sold as a factory motard, with road wheels and tyres, electric start, and updated faux radiator fairings. XR 500 / XR 500R Introduced in 1979, the twin-shock Honda XR 500 was the first "XR" model. The
