Honda’s Kevin Aschenbak gives Justin Jones the breakdown on how easy it is to set up the 2013 Honda CRF450R’s air forks. Altogether, the 2013 CRF450R is one of the most race-ready motocross bikes ever offered to the general public, outside of a full-on fac‑ tory ride with Team Honda. It is that good. Better motor, Better chassis, Better suspension. Bet‑ ter mass centralization. Better almost everything. State-of-Art Air Forks Adding two more psi to the KYB Air Forks is the same as going up one spring rate on a conventional spring/ fork front suspension. By eliminating the conven‑ tional steel spring in the forks, Honda has shaved almost two pounds off the CRF450R’s front suspension. Plus, fine-tuning the spring rate is as easy as ad‑ DIRT ILLustrated \\\\\\ Vol. 1 + Issue 4 + Page 36 Honda’s four-stroke single engine gets a spring clutch design, to make it more justing air pressure on a tire— no special tools required. The 48 mm inverted KYB PSF (Pneumatic Spring Fork) improves tracking by getting the tire back on the ground quicker. By getting that weight off the front end it can stroke more freely and make quicker direction changes. The front end now gives you good track feedback and stays planted in the turns. Very tunable by us‑ ing air pressure. Stock air pressure is 33 psi, but by adding 2 more psi to the front end, it is the same as going up one spring rate on the front forks. Now, instead of
