Sitta Aluminium Rear Sprocket Aprilia RSV4 / RSV4 1100 Factory / R / RR / RF (2009-2026) – 37-48 Teeth, 520 Pitch (202P)

Finding the perfect rear sprocket for an Aprilia RSV4 is as much about daily riding comfort as it is about outright performance. The Sitta 202P aluminium rear sprocket lets you dial in your gearing with twelve tooth options — from 37 to 48 teeth on a 520 pitch — so every ride, whether a weekend blast on the road or a full track day, feels exactly as it should from the first corner to the last.

Key Features

• Lightweight, high-grade aluminium construction strikes an ideal balance between durability and unsprung weight reduction.
• Available in 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47 or 48 teeth, giving genuine flexibility to tailor acceleration and top speed to your riding style.
• 520 pitch compatibility across the full tooth range — ideal for standard and converted lightweight chain setups.
• Hard-anodised finish option delivers superior surface hardness and corrosion resistance for extended service life.
• Five-hole sprocket carrier pattern 100/120-5 ensures a precise, rattle-free fit directly to the Aprilia hub.
• Eight colour choices — silver, black, hard-anodised, red, gold, blue, orange and green — allow a clean visual match to any RSV4 livery.

Aluminium Quality and Finish

Sitta machines the 202P from high-grade aluminium alloy, keeping rotating mass low without sacrificing the structural integrity that a high-power V4 demands. The standard anodised surfaces resist everyday wear and corrosion well; the hard-anodised variant goes a step further, building a noticeably tougher surface layer that holds up on track where chain loads are highest and replacement intervals matter most. All colour options retain the core anodised treatment, so the finish is integral to the material rather than a superficial coating that chips or flakes.

Choosing the Right Tooth Count

The gearing choice you make here changes the character of the motorcycle in a very tangible way. Fitting a smaller sprocket in the 37-to-42 teeth range shortens the overall gearing ratio, raising top speed and reducing engine revs at motorway cruising speeds — a sensible choice for long-distance road riders or circuits with extended straights such as Hockenheim or Mugello. Moving up through 43 to 48 teeth lengthens the ratio, sharpening throttle response and intensifying acceleration out of slow corners — exactly what a tight, technical track like Oschersleben rewards. Because the Sitta 202P is available across this full range at 520 pitch, you can experiment and refine without sourcing a different carrier or chain standard.
