Yamaha WR250X, The Amazing Ride

Although Yamaha WR250X will not belongs to the big ten of motorcycle with the best design but doesn't mean that this motorcycle designs then will get the bad effect. Functionally, motorcycle design that fuse off road bike and street bike like such is really steady and as according to beginning plan yamaha building this motorcycle. Looks like, The Yamaha WR250X is resemble with trail motorcycle (offroad bike) commonly uses for hard roadfield. But when seeing the tyre used, likely Yamaha designs this motorcycle for highway consumption. With slender design and briefly, this motorcycle chasis is really designed based on trail motorcycle (offroad bike). The idea is designing a nimble motor that can be used in city. Four stroke engine DOHC 250cc installed in wr250x is designed based on engine of Yamana YZ-F engine that demoted in product series of motocross. This Engine that uses liquid cooling system is not really designed for speeding and because of such thing, the maximum speed limit that can be reached only around 130km/ hour. It is clearly not good match for engine 250cc installed. Possibly, fuel efficiency is the one of the consideration by Yamaha that claimed that this motor can run over 30km to every litre of fuel. With tank that can accommodate fuel 7,5 litres, you can pass through over around 226km, that is even still depending from your manner of riding this motor. For use in city, possibly that number can be more going down.

Because of use of construction of motorcross, it is clearly from this motorcycle control is superior. Long handlebar makes lighter the rider in doing manouvre. manouvering through empty roadside when you'e trapped in trafficjam is the one of this motorcycle superiority. Motorcycle news called that this motor is nimble but difficult to turn in high-speed without lossing of balance. They say that this motorcycle's rear suspension is a little less stable while turning. Several other weaknesses that also be said that motorcycle height is idealless for majority of people so that making difficult when must stop on midway. While, the seat construction is even also pleasantless and making the rider feels tired fast. Besides, Yamaha doesn't also prepare kick starter and you must always ascertain accumulator in good condition, except that you don't mind pushing this motorcycle that has weight as heavy as 135kg.
