American Honda gave the media an exclusive look at the all-new 2018 Honda CRF250R, which features a new engine, chassis, and suspension.
The new engine utilizes a dual overhead camshaft (DOHC) design, which is a drastic change from the former "Unicam" design that was used since the bike's inception in 2004. Another major change to the engine is the the dual exhaust ports that have a header pipe exiting from both sides of the cylinder head. Also, the engine now comes equipped with electric start and the kickstarter has been removed.
The new generation frame and bodywork are similar to the 2017 and 2018 Honda CRF450R as well as the coil spring Showa front fork and titanium fuel tank.
As for the big question of when this bike will be available, Honda will have a production bike on display at Loretta Lynn's, and you can expect to see a few laps from Andrew Short on it if you're at the event. The bikes will be introduced to the media most likely in October, so do not expect to see them on the showroom floors until very late in the year.
