2017 HONDA CRF450RX Announced
Baja Racing News LIVE! Exclusive!The RX does not mean the end of the previous CRF450X, a bike Honda says still fills the niche for the off-road rider who is looking for something more trail friendly, or an off-road bike more appealing for long-distance riding. As a result, the much-liked X remains in Honda’s lineup.
Some of the major differences between the R and the RX is that electric starting comes standard on the RX (with manual back-up) and the RX’s fuel tank is made out of plastic (not titanium) and is larger in capacity (2.2 gallons versus 1.6 gallons). The RX also has an 18-inch rear wheel, and gearing is slightly different.
The RX also has compared to the R:
- Smoother ignition mapping for better performance in low-traction situations.
- Standard electric starting, with kick start as a backup.
- Suspension settings are more appropriate for technical off-road conditions.
- With a 2.25 gallon capacity, the plastic fuel tank is larger than that of the CRF450R for increased range off-road.
- Forged-aluminum side stand is standard to allow trailside parking.
- Off-road-focused, durable Dunlop Geomax AT81 tires.
- One-tooth larger rear sprocket than CRF450R, for better performance in tight woods conditions.
- Different cylinder hanger than CRF450R, for comfort in technical off-road conditions.
