Honda CRF450R 2009-2016 Service Manual

Power comes from a 449cc liquid-cooled single, delivering drive through a close-ratio 5-speed transmission. Autoevolution's own confirmed account marks the genuine 2009 turning point that opened this range: "the bike was similar to previous models but dropped the carburetor and gained a Programmed Fuel Injection (PGM-FI) system" — real, fundamental fueling-system change from the carbureted second generation before it, run through a 48mm inverted KYB adjustable fork (310mm travel) and a Pro-Link swingarm with a KYB adjustable shock (320mm travel).

Autoevolution's own confirmed account details the genuine, comprehensive redesign that opened the fourth generation within this range: "the 2013 model year came with some modifications, which included the addition of a twin exhaust system to centralize mass and changes to the suspension system, which included a KYB air-assisted fork. Further changes were made in the following years, including a new exhaust system, revised cylinder head, and updated EFI settings in 2014, a Showa Triple Air Chamber (TAC) fork and an engine mapping switch in 2015, and a longer fork, revised ignition mapping, and a lighter swingarm in 2016" — real, genuine hardware evolution worth knowing for correct year-by-year parts identification within this fourth-generation half of your listed range.

Ultimate Motorcycling's own confirmed 2016 testing details the specific suspension refinement closing out this range: "the 2016 Honda CRF450R receives a 5mm longer fork, a new rear suspension link, revised rear suspension settings, more adjustment on the rear suspension damping, and a smaller diameter chain roller," noting the bike's genuine competitive record through this era — "the bike has been piloted to a plethora of Monster Energy AMA Supercross main event race wins by the likes of Trey Canard, Cole Seely, and Eli Tomac," with a podium finish at every round of the 2015 Supercross season.

Because this exact 2009-2016 range spans two genuinely distinct Honda generations sharing similar external appearance but real internal differences — fuel-delivery hardware, fork type (air versus coil-spring KYB), and exhaust configuration — correct year identification against the specific frame and engine number remains essential before ordering suspension or fuel-system parts.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2009-2016 CRF450R running the way it was built to.
