Moriwaki MD250H riding impression


The Moriwaki MD250H. An exquisite little racer for those who can afford it...

Last year, American Honda and Moriwaki Engineering had announced the availability of a limited number of MD250H racebikes. The bike was meant for young racers who wanted to take part in the USGPRU roadracing series.

An exquisite piece of engineering, the Moriwaki MD250H is fitted with a four-stroke, liquid-cooled, single-cylinder 249cc engine from Honda. Also used in the Honda CRF250X, this engine is specially tuned and fettled by Moriwaki, for the MD250H.

The MD250H is a serious bit of equipment, a proper small-bore GP bike. Custom fabricated twin-spar aluminum chassis, radial-mount calipers for the front disc brake, USD fork, Honda’s Pro-Link rear suspension, lightweight wheels, race-spec tyres and works-style welded aluminum fuel tank – the MD250H is pure racer all the way.

At its list price of US$11,699 the bike isn’t cheap, but for young racers who’re rich enough to afford one, it’s probably the real deal all right. The guys at Motor Box recently got to ride an MD250H, and here are some excerpts from what they have to say about the Moriwaki machine:

The Moriwaki MD250H is the perfect ‘school’ for kids with motorcycle racing aspirations. The bike has a sophisticated chassis and the suspension is fully adjustable, and yet, there are none of the complications associated with running a two-stroke racebike here.


For teenagers who weigh not more than 50 kilos, and who can corner like Max Biaggi, the Moriwaki MD250H can probably provide a bagful of thrills...

The bike is very compact and the riding position is tight for anyone who’s used to bigger bikes. The MD250 weighs only 90 kilos and tyres are about as wide as those on a mountain bike. As you would expect, the bike is very agile, with very high cornering speeds. The brakes are also very good, very aggressive.

However, it’s the engine that’s really surprising. With about 40bhp at the rear wheel, the engine pushes hard from 8,000rpm onwards, singing all the way up to 13,000rpm. However, the gear ratios – the same as those used on the Honda CRF250X – are less than ideal on the MD250H. Sort that out, and you’ve got one hell of an interesting machine here…
