It rocks all the features and upgrades of our latest CRF450R, but has some special touches that fine-tune it for enduro use. Like a bigger fuel tank. A sidestand. An 18-inch rear wheel. And special suspension settings. Along with the CRF450R, it gets an all-new chassis and swingarm, new fuel-injection settings that spray twice per cycle to better atomize the fuel, a special launch-control setting, new Renthal Fatbar and all the rest. Weve never built an enduro bike this race-ready. And neither has anyone else.
