Honda CBR650R mods & upgrades

The CBR650R shares its 649 cc four, frame, swingarm, fork and brakes with the CB650R, so most non-bodywork parts are listed for both bikes. Fitment splits at 2021 (fork) and 2024 (restyle and E-Clutch), so buy by year, not by model name.

1. Fit a fender eliminator

   TST's Elite-1 kit lists the CB650R and CBR650R 2019–2023 on one part. The 2024 restyle brought a new seat unit and taillight (Honda), so look for a 2024+ listing before ordering for a newer bike.

2. Add sliders and check the right-hand cover

   Puig R19 frame sliders come as 2019–2023 and 2024–2026 kits; Womet-Tech frame sliders list the CBR650R, CB650R, CBR650F and CB650F. On 2024+ bikes the E-Clutch actuator sits inside the right-hand engine cover, so confirm any right-side cover or slider kit lists E-Clutch bikes.

3. Choose a full system

   Akrapovič (Racing Line) and Hindle (Evolution and Evo-Megaphone) list full systems for this bike; we found no slip-on from either. Akrapovič sells separate O2-sensor fitting kits for 2019–2023 and 2024–2025 bikes and marks the Racing Line as not emissions-compliant for street or highway use.

4. Swap levers and add grips

   Womet-Tech's Evos shorty levers list the CBR650F, CB650F, CB650R and CBR650R on one kit; TechSpec Gripster tank grips list the CB650R and CBR650R 2019+. E-Clutch bikes keep a working clutch lever (Honda), so lever sets still apply. Check that a 2024+ listing names your bike.

5. Change the windscreen

   Puig's Z Racing windscreen lists the CBR650R 2019–2026 as one part.

6. Decide on a quickshifter by year

   2019–2023 manual-clutch bikes: Honda Europe lists an accessory quick shifter for the CBR650R (confirm US availability with a Honda dealer), and Woolich sells a plug-and-play quickshifter package for 2018–2019 CB650R/CBR650R. 2024+ E-Clutch bikes shift up and down without the clutch lever (Honda), so skip it.

   Quickshifter

1. Set sag and pressures, then buy tires

   Stock sizes are 120/70-ZR17 on a 3.5-inch rim and 180/55-ZR17 on a 5.5-inch rim (Honda Europe spec), so standard sport and track tires in those sizes fit without a wheel change. Honda's US spec sheets list sizes only, not the OE brand.

2. Refresh the brakes

   The radial-mount Nissin four-piston calipers and 310 mm floating discs stay. EBC lists Double-H sintered front pads for 2019–2024. Add braided lines, fresh fluid and a lever guard; check your track-day organizer's rules on guards.

   BrakesLevers

3. Spring the fork, then fit a shock

   Öhlins lists an STX46 shock (S46HR1C1) for 2019–2024. Up front, start with springs for your weight. The fork is an SFF on 2019–2020 bikes and an SFF-BP from 2021, so buy fork parts by year.

   Suspension

4. Check rearset listings by year

   We found no rearset kit for the CBR650R at Sportbike Track Gear; ask a vendor to confirm your year before ordering. On E-Clutch bikes Honda's system reads pressure on the shift pedal, so choose a kit that lists E-Clutch fitment.

   Rearsets

5. Protect the covers and axles

   GB Racing lists a CBR650R engine cover set and alternator cover for 2021–2023 (its CB650R sets run to 2025); Puig lists front axle sliders for 2019–2026. On 2024+ bikes the right-hand cover houses the E-Clutch actuator.

6. Regear, then flash with a full system

   Stock is a #525 chain with a 15T front and 42T rear sprocket. SprocketCenter lists 525 kits and 520 conversion kits for 2019–2026; the usual track change is one tooth down in front or two to three up in the rear. Pair a full system with an ECU flash: Woolich lists 2018–2020, 2021 and 2022–2026 definitions.

• CBR650F2014–2018

  The predecessor: 649 cc four with a conventional Showa fork (Dual Bending Valve from 2017), dual 320 mm discs with two-piston Nissin calipers, and different bodywork and ergonomics. Bodywork and screens do not cross to the R. Some engine-side parts do: Akrapovič lists one full system for the CBR650F/R and CB650F/R 2014–2020, and Womet-Tech sliders and levers list all four 650s.

• 2019–2020 (launch)2019–2020

  CBR650F becomes CBR650R: 41 mm Showa SFF inverted fork, radial-mount four-piston Nissin calipers on 310 mm floating discs, assist/slipper clutch, clip-ons moved under the top clamp, LCD with gear-position and shift-up indicators, redline raised 1,000 rpm to 12,000. US 2019 bikes came with or without ABS, and HSTC traction control only on the ABS version; Honda US's 2020 spec sheet lists only the ABS version.

• 2021–2023 update2021–2023

  Showa SFF-BP (big piston) fork replaces the SFF, which Honda calls a major upgrade to the front suspension, so fork internals are year-specific. Euro 5 changes touched the ECU, cam lobes, intake timing, exhaust and catalyzer. New side panels and plate holder, and a clearer LCD. Woolich keeps a separate 2021 ECU definition.

• 2024+ (E-Clutch)2024–present

  New bodywork with a slanted LED headlight and new taillight, a 5-inch optically bonded TFT, revised ECU and catalyzer, and Honda E-Clutch: a two-motor actuator inside the right-hand engine cover. Honda US lists the 2024, 2025 and 2026 CBR650R as one E-Clutch version; Honda Europe sold E-Clutch as an option. Slider, tail-tidy and O2-fitting-kit listings split here.
