Since its 2002 introduction, the CRF450R has earned an enviable racing pedigree, and the 2018 edition is the best yet, with superior technology and style. During a successful debut year with the “Absolute Holeshot” philosophy that achieved optimum power and centralized mass, the revolutionary CRF450R has become the industry’s top-selling 450cc motocrosser. For 2018, an electric starter is now standard, powered by a lightweight lithium-ion battery. CRF450R upgrades for 2018 also include updated suspension settings aimed at improving chassis feel and overall action, and new ECU settings for a more useable power delivery.
