Honda CB650R RA ABS 2021-2023 Service Manual

Visordown's launch coverage called the 2021 update the CB650R's biggest overhaul since the Neo Sports Café design first appeared in 2019 — and the changes went well beyond a fresh coat of paint. Ultimate Motorcycling's own first-look zeroed in on the headline item: a fully adjustable 41mm Showa Separate Function Front Fork Big Piston (SFF-BP) unit replacing the previous non-adjustable fork, adding compression and rebound damping adjustment on top of preload, while being both lighter and more rigid than the unit it replaced.

Power comes from a 649cc liquid-cooled inline-four, DOHC with cylinders canted forward 30 degrees for a compact package, delivering a claimed 95 hp with peak torque arriving at a high-revving 8,500 rpm — genuinely built to reward riders willing to wring it out, with power optimized specifically in the 10,000-12,000 rpm range. For 2021, Honda reworked cam lobes, the crank pulsar, ECU mapping, intake timing, and the exhaust system specifically to meet Euro5 emissions standards, while keeping peak power unchanged and only marginally reducing peak torque. A 6-speed gearbox with an assist-and-slipper clutch — lightening lever effort by roughly 12% over the previous design — and Honda Selectable Torque Control round out the electronics.

Ergonomic refinements addressed real owner feedback: handlebar angle increased 3 degrees to 35 degrees for easier low-speed maneuvering and U-turns, a larger, easier-to-read LCD dash font and angle fixed one of the most common complaints about the outgoing model, and a USB-C port appeared under the 31.9-inch seat for on-the-go charging. Braking comes from radial-mounted four-piston calipers gripping dual 310mm front discs, paired with a 240mm rear disc, all wrapped in the CB650R's distinctive Neo Sports Café styling — a slanted LED headlight, compact "Trapezoid" tank proportions, and a sharp, minimal tail section. 2023 brought no significant changes beyond a new color option, closing out this generation before the more substantial 2024 redesign introduced Honda's E-Clutch technology. A 4.1-gallon fuel tank and 202 kg (445 lb) wet weight round out the package, with 2023 pricing starting at $9,399.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2021-2023 CB650R ABS running the way it was built to.
