Yamaha XT 250

from Wikipedia, the free encyclopedia
Yamaha XT 250, manufactured in 1981

The XT 250 is a Japanese enduro from Yamaha that was built from 1979 to 1990. It is considered the little sister of the successful Yamaha XT 500 model . In contrast to this, however, it has an electronic ignition and a cantilever swing arm with a central shock absorber under the tank like the Yamaha XT 550 .

In Germany the motorcycle had an output of 13 kW / 17 PS .

Yamaha has been manufacturing a new generation of the XT 250 since 2008. It is sold in America and Canada, for example. Except for the name, the machines don't have much in common with the original XT 250. The current version has disc brakes at the front and rear and an electric starter. Like its predecessor, it has a 2-valve engine, which was actually considered obsolete in the 1980s. Competitive models such as the Kawasaki KLX 250 or the Honda XL 250 had 4-valve engines.
