YAMAHA’S NEW OFF-ROAD TWO-STROKE
The result was the end of trail-oriented two-strokes, at least as far as Japanese bikes go. Europeans, on the other hand, kept right on importing them. It’s taken this long for the rank-and-file engineers and test riders at Yamaha to convince upper management that they can do the same thing. A bike can be designed for off-road racing and be imported as a closed course competition bike; the two aren’t mutually exclusive.
Design-wise, the YZ250X is somewhat conservative. It isn’t an electric-start 300 as some pundits speculated. Yamaha was already risking a lot without the massive retooling that an all-new motor would have required. But, if the X is successful, it could lead to more of its kind.
