Honda CRF450R Preview

Honda has always been a leader in the MX / SX and off-road motorcycle scene. And for 2011, the manufacturer wants to continue this trend by adding more improvements on their largest motocrosser, the CRF450R.

Honda revamped the CRF 450 R for 2011, tweaking the engine for more low-end and midrange grunt while improving throttle response. Also, Honda has upgraded the suspension with the all-new Honda Progressive Steering Damper (HPSD).

Bill Savino (Powersports Press Manager) says: “We’re proud to unveil our newest race bikes, the CRF450R and CRF250R motocrossers, plus a wide assortment of Honda off-road machines that have remained extremely popular with recreational riders over the years. With these models for 2011 and more to follow, this is certainly going to be a great year for riding enthusiasts.”

New For 2011:

  • Revised engine tuning and new 46mm throttle body increase low-end and midrange power and give improved throttle response.
  • Front fork features a lighter cartridge cylinder and all-new valving for improved control and increased ride plushness.
  • Revised shock valving yields improved control and increased rear wheel traction.
  • New suspension linkage produces improved chassis balance and increased rear wheel traction in rough-track conditions.
  • Honda Progressive Steering Damper (HPSD) features larger piston diameter (20mm to 24mm) for improved tracking traits.
  • Redesigned muffler lowers sound emissions to 94 dB.
