The 2010 Honda CRF450R Dirt Bike Motorcycle

Feelin out the power of the CRF450R

The Honda CRF450R Motorcycle returns in 2010 to take its rightful place at the head of the class, With class-leading power and handling, the Honda CRF450R features the perfect blend of power, suspension and handling for a genuine revolution in the premier motocross class.

No wonder the award-winning Honda CRF450R has won more magazine shootouts than any motocrosser in modern history.

This year’s engine got a significant overhaul and remains essentially the same. The water-cooled lump still displaces 449cc via a 96.0 x 62.1mm cylinder measurement.

Fuel is compressed to a respectable 12.0:1 compression ratio. Honda’s proprietary Unicam design ensures a compact cylinder head by using a solo camshaft to actuate the mixed titanium/steel valvetrain.

For 2010, Honda has updated both the fuel and ignition maps, further enhancing an already friendly powerband. The new mapping is also said to aid in starting via a revamped auto-engine-decompression system. While the ’09 bike was definitely finicky to start, we’re pleased to report that this trait has been eliminated with the ‘2010 Motorcycle.

This new generation Honda CRF says hello to a radically altered chassis. It’s highlighted by a fifth iteration of the twin-spar aluminum frame that engineers designed with three things in mind: nimble handling, compact shape, and minimal weight. The biggest change is the steering head and front wheel being repositioned closer to the rider. Also, the space between the fork tubes and the steering head (triple clamp offset) was reduced down to 20mm, making the bike much easier to steer.

Everything else that we’ve come to expect from the Honda CRF450R is still there. The brakes are as strong as ever, and the bike turns great, handles well, and just feels tight and compact as always. And it feels light, too, as it should – at a claimed 238.4 pounds, it’s roughly 10 pounds lighter than most of the bikes in its class.
