2017 Honda® CRF450R The Ultimate Holeshot Machine. Open-class motocross might as well be called the unlimited class. There’s no room for anything but the best here, and the best keep getting better and better every year. Well, have no fear, because the all-new 2017 Honda CRF®450R is here. Major improvements everywhere, especially to the engine’s increased power and peak torque, help drive you to the front of the pack. There’s even an optional electric starter this year. And when you’re in the lead in the first turn with an empty track in front of you, it’s a whole new kind of race. Features may include: Downdraft Fuel Injection Part of an entire engine overhaul for 2017, the new downdraft intake tract and FI body help and increase both power and fuel-metering precision. It’s part of the reason the CRF®450R offers such explosive power and massive torque, especially out of the starting gate and in the critical first 100 feet of the race to the first turn. New Showa® Spring Fork An all-new 49mm Showa® fork features a conventional spring design that helps increase the CRF®450R’s front-suspension precision, handling and feel. Next-Generation Aluminum Frame New for 2017, our Next-Gen twin spar aluminum frame positions the new rear shock’s mounting point lower, opening up the airbox area and contributing to a lower center of gravity for more holeshots. The frame geometry also helps improve traction, feeling and steering precision.
