For 2015, Honda has come out with a host of changes, including larger front rotors, new Dunlop MX52 tires, new electronics and an engine mapping selection button. Biggest of all, however, are the two new suspension systems from Showa and KYB.

The 2015 CRF250R features its own version of Showa's SFF TAC system. The air spring is managed inside the right side fork, while the left side takes care of the damping. Because the left side fork already has a brake caliper mount, the third air chamber (TAC) is located inside of the left fork lug. The damping side fork also features a larger base valve piston and shim size compared to other models featuring this new fork.

The 2015 CRF450R comes equipped with KYB's newest PSF fork. The new forks feature high- and low-speed rebound adjustments on the right side fork, while the left fork has high- and low-speed compression adjustments. In the rear, there's a new shock adjuster, based off the same unit in use by KYB's factory race teams. The rebound adjustment has been moved from the bottom of the shaft, up into the housing of the adjuster. Now rebound, high- and low-speed compression adjustments are made from the housing on the top of the shock body.

Availability on the 250 ($7599) is August, and September for the 450 ($TBD).
