The 2017 HONDA CRF450RX Exclusively Announced

2017 HONDA CRF450RX Announced

Baja Racing News LIVE! Exclusive!

Honda introduces the new CRF450RX, a closed-course off-road (GNCC) version of the 2017 CRF450R motocrosser.

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.

Electric starting comes standard on the CRF450RX.

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.

Like the 2017 CRF450R, the RX will makes its dealer debut in October but shortly after the R. Price has not yet been announced.
