Honda CBR600RR mods & upgrades

The CBR600RR is the longest-running essentially-unchanged supersport you can still buy new in the US — which means eighteen years of race development, setup sheets and used parts apply directly to a current-model bike. It's the known quantity of the 600 class: nothing exotic, everything solved.

1. Tail tidy

   Fender eliminator and flush signals — Motodynamic and TST own the Honda fitment. The stock rear hanger is as dated as the platform's spec sheet.

2. Sliders and case covers

   Frame sliders plus case protection. PC40 stator and clutch covers are known crash casualties and OEM replacements aren't cheap.

3. Slip-on and levers

   Yoshimura is the traditional Honda pairing — RS-family slip-ons everywhere — with Akrapovič and Two Brothers behind. Add adjustable levers; the stock ones are crash-bait.

4. Fueling

   The US ECU is conservative and historically locked-down. A flash (FTECU covers the PC40) or classic Power Commander smooths the midrange the EPA map flattens.

5. Suspension set for you

   2013+ BPF bikes respond to springs and setup; 2007–12 forks are older tech and benefit even more. Sprung for your weight beats any bolt-on.

6. Grip and wind

   Tank grips and a Zero Gravity double-bubble. The RR's race-derived tuck rewards both.

1. Tires and tank grips

   Supercorsa SP or Q5 in stock sizes plus Stompgrip/TechSpec. The chassis is better than any street rubber you can put on it.

2. Brakes: the classic RR recipe

   Brembo RCS 19 master cylinder, race pads and braided lines — the community's step one of CBR600RR race prep, and it transforms the front end for under $700.

3. Suspension sprung for your weight

   Cartridges (Öhlins, K-Tech) for 2007–12 forks, springs-and-valving for 2013+ BPF, and a quality shock. Watch the fitment windows — Öhlins lists different shock variants across PC40 years.

4. Ergonomics

   Woodcraft or Vortex rearsets and clip-ons. PC40 control fitment has been stable since 2007, so used race take-offs are plentiful and cheap.

5. Make it crashable

   GB Racing covers, race glass (the 07–12 and 13+ molds differ), sliders, spools. A prepped RR is one of the cheapest 600s to crash and rebuild.

6. Unlock the engine

   Full system plus real tuning — flash or, for race builds, the classic HRC kit route. The stock US map leaves the top end asleep; this is where the RR's power actually lives.

• PC372003–2006

  The original RC211V-inspired RR. The 2005–06 update brought an inverted fork, radial brakes and new bodywork — early and late PC37 parts largely don't cross.

• PC402007–2012

  All-new, dramatically lighter platform. Optional combined ABS from 2009 (heavy, complex — most track builds start from non-ABS bikes). The classic used track-day 600.

• PC40 (2013 update)2013–present (US)

  Showa Big Piston Fork, new wheels, revised fairing on the same frame. This is the bike the US still sells new today — no winglets, no IMU, cable throttle. Two decades of parts knowledge apply almost unbroken.

• 2BL-PC40 / PC692021–present (Japan/EU only)

  The international update: winglets, throttle-by-wire, HSTC (nine levels plus off is stated only for the 2024 European bike; Honda's 2021 Japan release gives no level count), TFT dash (Japan 2021 as 2BL-PC40; the 2024 European relaunch is commonly cataloged as PC69). Never sold new in the US — parts for it frequently don't fit US bikes.
