First Look: 2010 Honda CRF250R-CRF450R

New top-flight 250cc off-roader gets complete makeover and fuel-injection

Fuel injection for Honda's 2010 CRF250R

HONDA UK have unveiled the all-new CRF250R and updated CRF450R off-road machines.

The CRF250R has received a full revision for 2010, with even more power, coupled with a lighter weight chassis and enhanced handling.

The new CRF250R will be equipped with the advanced fuel-injection system from the 2009 CRF450R, which delivers a wider spread of power with improved delivery, mated to a lighter single-muffler exhaust system, says Honda.

Pistons are made from a new, more durable material, while valve springs are made from the same material used in Honda’s RC211V MotoGP machine. A new radiator keeps the 249.4cc liquid-cooled four-stroke cool whilst new gear ratios also ensure optimum drive.

The 250’s bigger brother, the CRF450R, has also received some updates to keep it ahead of the chasing pack. At the heart of the CRF450R, new ECU programming and fuel-injection settings improve throttle response even further, while the 449.7cc liquid-cooled motor also benefits from a new engine auto-decompressor system for easier kick-starting. Further revisions include the HRC fuel-injection tool now able to be attached without removing the tank and new seals on the front forks with improved valving and oil quantity to give a more planted feel and provide a smoother ride across rough terrains. Meanwhile, the rear shock now features an updated piston and a re-designed compression adjuster for improved damping.

The CRF450R will be available from Honda (UK) Motorcycle Dealers from September, with the all-new CRF250R available just a month later from October. Prices will be announced closer to this time.
