What's the difference between CRF450X and CRF450RX?
Unlike the barking CRF450R and CRF450RX, the X subdues the throttle response, focusing on retaining traction regardless of the terrain's challenges. Honda achieves this by giving the CRF450X its own cam profile and piston, while increasing the crank mass.
The defining characteristic of the Honda 450RX is power—lots and lots of power. The CRF450R is already considered the brute of the motocross world. As an off-road bike, the RX is a little over the top, but in a fun, exciting way.
Power feels as if it were electric, as wherever you are in the motorcycle's gearing and rpm range, you have access to all of its 55 horsepower and 35 pound-feet of torque.
However, the CRF450R is not far behind with 53.8 hp at 9,300 rpm. As far as peak torque, Big Red's 34.1 pound-feet of torque at 7,200 rpm slots it in the runner-up spot behind the 450 SX-F. Honda owners can take solace in the fact that the CRF450R is still the fastest-feeling bike in the segment though.
The most powerful and fastest dirt bike currently, is the KTM 450 SX-F, a 450cc bike with a top speed of 123 mph. The 450 SX-F was a Motocross Champion under rider Ryan Dungey in the dirt bike category.
If you're a sucker for power, the CRF450R is a great choice for an open-class racer just getting started. She's got tons of power, whilst still being usable and easy to ride for a beginner.
