The XL 250 is an enduro from the Japanese manufacturer Honda and was created in 1973 from a renaming of the SL 250 S , which was first launched on the market shortly before in 1972 , which, with its 4 valves and an overhead camshaft (OHC), laid the foundation for all enduros at Honda put.

Model history

In the 1960s, scramblers were very common - street motorcycles with a higher seating position, the off-road mobility of which was slightly improved by means of coarse tires and raised exhaust systems. At the end of the 1960s, Honda launched a series of SL models that initiated the transition from Scrambler to Enduro. The SL 250 came on the market in 1972 and established a series of successful and (then) modern enduros at Honda, which were manufactured until the late 80s. Since this should also be recognizable in the model name, the SL 250 was renamed the XL 250 in 1973. In Germany, the XL 250 was offered from 1974.

technology

Similarities

All models had drum brakes at the front and rear, whose low effect takes some getting used to, at least on the road. The machines have a relatively small oil supply, but do not have an oil pressure light or an oil filter, so regular oil checks or oil changes are highly recommended. A common problem with the engines is (similar to the larger XL 500 model ) leaks in the valve cover and cylinder head, caused by insufficiently dimensioned stud bolt threads, which after a while can no longer absorb the forces that occur.

differences

The models up to 1981 (designation "S") had a conventional swing arm with two shock absorbers, a 23 inch front wheel and a 6 volt electrical system. From 1982 (designation "R") a mono spring strut with a lever deflection was used. This system was called Pro-Link and was manufactured by the Shōwa Corporation . Furthermore, the 23-inch front wheel was replaced by a 21-inch one and the 6-volt electrical system was replaced by a 12-volt one. Among other things, the engine received a modified timing chain tensioner . The S models had a five-speed gearbox, the R models six.

successor

In 2012, Honda introduced a completely redesigned successor, the CRF 250 L.
