Sitta Aluminium Rear Sprocket Honda CBR 600 RR PC37, PC40 & PC69 (2007-2026) – 525 Pitch, 37-48 Teeth (201N)

Keeping your Honda CBR 600 RR running smoothly day in, day out starts with a reliable drivetrain — and the Sitta 201N aluminium rear sprocket delivers exactly that. Available in twelve tooth counts from 37 to 48 and eight colour finishes, it lets you fine-tune your gearing for your exact riding needs without compromise on quality or longevity.

Key Features

• Lightweight aluminium construction keeps unsprung weight low while maintaining the structural integrity needed for sustained road and track use.
• Tooth counts from 37 to 48 give you genuine gearing flexibility — dial in top-speed-biased ratios at the lower end or sharper acceleration at the higher end.
• 525 pitch only — precisely matched to maximise chain-to-sprocket engagement and extend the service life of your entire drive chain.
• Sprocket carrier pattern 134/160-6 bolt for a straightforward, accurate fitment with no modification required.
• Eight finish options including hard-anodised (more durable than standard anodising), black, red, blue, silver, orange, gold and green — choose the finish that suits your bike's look and your budget.
• Part number 201N — easy to reorder and cross-reference when replacing worn components.

Choosing the Right Tooth Count

Gearing has a direct impact on how your CBR 600 RR behaves on the road or circuit. Getting it right costs nothing extra but makes a noticeable difference to everyday rideability.

A smaller rear sprocket in the 37-to-42 tooth range raises overall gearing, reducing engine revs at motorway cruising speeds and extending top-end reach — a practical choice for riders who cover longer distances or want a more relaxed power delivery. Moving up to the 43-to-48 tooth range shortens the overall ratio, sharpening throttle response out of corners and improving pull from lower speeds. This suits more spirited riding, track days, or urban environments where brisk acceleration matters more than outright top speed.

Either way, the Sitta 201N slots straight onto your existing carrier without any fuss, so experimenting with gearing is a straightforward and cost-effective way to personalise your ride.

Construction and Finish

The 201N is machined from high-grade aluminium, striking the practical balance between weight reduction and wear resistance that most road and occasional track riders actually need. The hard-anodised option is worth considering if longevity is a priority — this surface treatment penetrates deeper into the metal than standard anodising, resisting abrasion and corrosion more effectively over time. The remaining colour options — black, silver, blue, red, orange, gold and green — use a quality anodised finish that holds its appearance well under normal riding conditions and adds a clean visual accent to the drivetrain.
