DescriptionThe whole story▼

Finding a front sprocket that holds up through daily commutes, long weekend rides, and the occasional track day is harder than it sounds — the Sitta 7131 makes it straightforward. Machined from high-strength chrome-molybdenum steel and available in five tooth counts from 13 to 17, this sprocket gives Kawasaki ZX-10R and ZX-10RR owners a practical, durable way to dial in gearing without paying a premium for parts that outlast the chain.

Key Features

  • Chrome-molybdenum steel construction delivers outstanding resistance to wear under sustained hard use on road or track
  • CNC-machined for precise power transfer and straightforward, no-fuss installation
  • Five tooth options — 13 through 17 — cover everything from short, punchy urban gearing to relaxed motorway cruising
  • Designed exclusively for 520 pitch chains, keeping compatibility clear and fitment exact
  • Covers Kawasaki ZX-10R and ZX-10RR production from 2016 all the way through 2026

Build Quality and Everyday Value

The Sitta 7131 is manufactured from chrome-molybdenum steel — the same alloy class used in motorsport applications where strength-to-weight ratio and fatigue resistance matter. The CNC machining process ensures each tooth profile is consistent, which means quieter engagement, even chain wear, and longer service intervals. Whether you are replacing a worn original sprocket or switching pitch as part of a chain kit upgrade, the 7131 slots in cleanly and requires no modification.

Note: the product image shows the Sitta Z001 model, which is visually very similar to the 7131. No official product image for the 7131 is currently available.

Choosing the Right Tooth Count

The tooth count you select directly shapes how your ZX-10R behaves out of a corner, on a fast motorway stretch, or at the end of a straight. A smaller 13-tooth sprocket shortens the overall gearing ratio, sharpening acceleration and making the engine feel more responsive — useful for technical circuits and twisty B-roads. Moving up to a 17-tooth sprocket lengthens the ratio, reducing engine revs at cruising speed and raising top speed potential on longer runs. The three intermediate sizes let you find the sweet spot for your specific riding mix without committing to an extreme either way.

Fitment and Compatibility

The Sitta 7131 front sprocket fits the following models:

  • Kawasaki ZX-10R Ninja (2016 – 2026)
  • Kawasaki ZX-10RR Ninja (2017 – 2026)

Compatible with 520 pitch chains only. Confirm your current chain pitch before ordering — this sprocket is not suitable for 525 or 530 pitch chains.
