Bike: 2015 Honda CRF450R

Hondas revamped 2015 CRF450R and CRF250R models have broken cover in the US. Stay tuned for an Australian release date and pricing structure, and changes that may be made to the Australian-spec models.

Key changes for Honda’s 2015 models include the addition of Dunlop MX52 tyres, larger front rotors, an engine mapping selection button and new electronics.

The 2015 Honda CRF450R comes standard with KYB’s newest Pneumatic Spring Fork (PSF), aimed to deliver five ways to adjust performance, with high-speed and low-speed adjusters for both rebound and compression damping settings, plus air-spring adjustability. The 2015 CRF450R receives a new cylinder head, aimed to increase top-end power and over-rev. The bike also receives revised ignition map settings and new settings for the Dual-Timing PGM-FI fuel injection, to help increase power.

Other key updates include:

New exhaust system uses larger-diameter pipe and exhaust outlet to aid top-end power.
Overall exhaust system length is much shorter and closer to the bike ‘s centre of mass for more agile handling.
Peak power hits earlier in the rev range and carries longer than before.
New piston is even stronger thanks to a new heat-treatment process.
New Engine Mode Select button — an industry first among motocross machines — allows the rider to easily select one of three different EFI/ignition maps to match each track/riding conditions.
HRC accessory tuning tool can be used to program custom maps actuated by the Engine Mode Select button.
New ACG flywheel incorporates more mass for smooth power delivery and enhanced low-end response, and makes it less prone to stalling or flame out.
Transmission gears are stronger for added durability.
New throttle return spring gives a lighter pull.
New clutch cable design gives a lighter pull at the lever.
New fork damper cartridge and other changes in fork construction yield a weight savings of more than 7 ounces.

New front/rear wave-style rotors with a larger 260mm front brake disc add to overall braking performance.
Front brake guide and radiator grill now feature a black finish
