While testing the 2014 version of the CRF450R, MotoUSA’s Adam Waheed observed that the machine’s powerband was “one of the most tractable and rider-friendly in the 450-class. It will be appreciated by all but those who are seeking a really aggressive and hard-hitting punch.” For 2015 Honda addresses this issue head-on with a revised mill that includes a brand-new, three-setting EFI/ignition map system. Big Red mounted an Engine Mode Select button which allows riders to cycle through Standard, Smooth and Aggressive settings to suit a variety of track conditions. With the aid of the optional HRC tuning tool riders can also program custom maps. Other engine improvements include a new heat-treatment on its piston as well as a revised cylinder head layout that allowed Honda to shorten the header by 320mm.
The 2015 CRF450R keeps the Dual-Timing PGM-FI fuel injection introduced last season, but has revised fueling and ignition settings for improved performance.
On the suspension side, the KYB PSF air fork, which made its debut on the premier-class motocrosser in 2014, remains. Honda asserts that updates to this year’s front suspension offer a wider range of damping adjustability. The rear Kayaba shock was also tweaked, now sporting a relocated rebound adjustment screw to help ease set-up. Braking performance is enhanced by a larger 260mm front wave-style rotor (up from 240mm in 2014).
MSRP is still to be determined, through Honda plans to have the new CRF450R in dealers by September 2014.
Honda also returns its CRF150R and CRF150RB-Expert option in 2015, though they didn’t receive any significant upgrades over the previous year’s iterations. They will be available September 2014 and price has yet to be determined.
The 2015 CRF230F and CRF150F get new graphics and styling to better resemble the CRF450R and CRF250R; price isn’t listed yet but they will be available August 2014. Finally, Honda brings the CRF125F and 125F Big Wheel version back to dealerships this year, having introduced the two models in 2014 as replacements for the CRF80F and CRF100F. Again, price is TBD with availability set for August 2014.
