2017 Honda CRF450R, 2017 Honda® CRF®450R 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 CRF450R 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 CRF450R 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 CRF450R 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.
2016 Honda CRF 450R, 2016 Honda® CRF® 450R Enhanced Podium Ability. Honda® s CRF® 450R is the nuclear option in the motocross wars. Light, powerful, nimble, responsive, it offers the most performance and refinement of any bike in its class. For 2016, we ve made some fine-tuning changes that make it a little better, but the big features that separate it from the pack remain. For example, there s the CRF® 450R s Engine Mode Select button that lets you choose between three settings (Standard, Smooth and Aggressive), just by pushing a handlebar-mounted button. Use that in conjunction with our available HRC Fuel Injection Setting Tool, and it s easier than ever to adjust your engine s output for specific track conditions. Next, the CRF® 450R's revolutionary KYB Air Fork features both high- and low-speed compression and rebound damping, letting you dial in the CRF® 450R's suspension in much quicker. Details like a fork that s five millimeters longer this year and a new shock link help make the CRF® 450R even more stable. There s even a new chain roller to help. All in all, you have everything you need to put you up front, from the second the start gate drops to when the checkered flag falls. Features May Include: Engine Mode Select Button Not to be confused with a launch mode selector, this handlebar-mounted button lets you dial in engine power delivery character with a push of your thumb. Choose between Standard, Smooth and Aggressive, depending on track conditions. Cylinder Head and Piston The CRF® 450R s cylinder head features a right-side exhaust port exit that helps the engine deliver more top-end power and over rev, plus better low-end torque feel. The piston s special heat treatment adds durability, too. KYB PSF Air Fork The CRF® 450R's 48mm inverted KYB PSF (Pneumatic Spring Fork) air fork is one of our 450 s best features. It weighs less than a conventional spring fork, and adjusting the spring rate is as easy pumping air. This year it s five millimeters longer too, which helps enhance the bike s stability.
