Honda CB650R mods & upgrades

The CB650R is the last affordable inline-four naked in its class — it sounds like a four, revs like a four, and wears the Neo Sports Café look that begs for tasteful hardware. It shares its platform with the CBR650R, so one aftermarket effectively serves two bikes.

1. Lose the barge board

   The stock plate hanger is enormous — a tail tidy is the single biggest visual upgrade on this bike. New Rage Cycles and TST make model-specific kits, mostly shared with the CBR650R.

2. Protect the headers

   The beautiful 4-into-1 header fan is also the first thing to touch down in a tip-over. Frame sliders (R&G, Puig) and case covers before anything cosmetic.

3. The slip-on

   Akrapovič's carbon slip-on is the canonical CB650R pipe; LeoVince LV-10 covers the budget end. Honest note: on this underslung 4-into-1 the gain is sound and weight, not meaningful power.

4. Contact points, café style

   ASV or CRG levers, bar-end mirrors for the Neo Sports Café silhouette, and fresh grips. Small-money changes with daily payoff.

5. Wind and comfort

   A Puig or MRA flyscreen takes the worst of the highway blast off your chest at 70+. Riders over the stock spring rates should add fork springs for their weight at the same service.

6. Shift quality

   Honda's accessory quickshifter is plug-and-play on non-E-Clutch bikes (2019+); Healtech iQSE is the aftermarket path. E-Clutch bikes already handle clutchless shifting their own way.

1. Tires and setup

   Bridgestone S23 or Michelin Power 6 handle track days at street-rider pace; set sag and pressures before buying anything metal.

2. Brake refresh

   Sintered pads and braided lines wake up the four-piston radial calipers; add a lever guard — most track orgs require one.

3. Suspension internals

   Cartridge kits and springs for your weight — but mind the split: 2019–2020 SFF and 2021+ SFF-BP forks take different kits. A Nitron or YSS shock replaces the basic stocker out back.

4. Ergonomics

   Rearsets (Gilles Tooling, Bonamici list the platform) raise pegs that touch down early. Verify E-Clutch compatibility on 2024+ bikes before ordering.

5. Make it crash-able

   Case covers (GB Racing, R&G) and axle sliders. A dropped naked bike at track pace eats headers and covers first.

6. Gearing and breathing

   A -1/+2 sprocket change sharpens drive out of slow corners; a full system plus fueling work is the last step and only worth it if you are chasing the sound as much as the numbers.

• CB650F2014–2018

  The predecessor. Related engine architecture, completely different bodywork and ergonomics — CB650R bolt-ons do not fit it.

• CB650R (launch)2019–2020

  Neo Sports Café debut: 649 cc inline-four, Showa SFF 41 mm inverted fork, radial-mount four-piston front calipers.

• 2021 update2021–2023

  Showa SFF-BP (Big Piston) fork and emissions updates. Looks nearly identical; fork internals and cartridge-kit fitment changed — the sneaky split on this platform.

• 2024 restyle2024–present

  New headlight and bodywork, 5-inch TFT dash, and Honda E-Clutch, the automatic clutch (standard on every US bike; Honda Europe sells it as an option). Slider, screen and tail-tidy fitment split here; E-Clutch bikes add their own clearance constraints.
