DescriptionThe whole story▼

When lap times matter and every gear change counts, the Sitta N002 front sprocket gives your Honda CBR 1000 RR SC77 the drivetrain edge it deserves. Machined from chrome-molybdenum steel and available in tooth counts from 14 to 17, this is a track-bred component that works equally hard on road and circuit alike.

Key Features

  • Chrome-molybdenum steel construction delivers outstanding durability and resistance to high-cycle wear under racing loads
  • Precision-machined teeth ensure exact fitment with zero play, reducing drivetrain slop for sharper throttle response
  • Available in 14, 15, 16, and 17 tooth options, letting you tailor gearing precisely to your circuit layout or road riding style
  • Compatible with both 520 and 525 pitch chains, covering standard and lightweight converted drivetrains
  • Motorsport-grade quality suitable for sustained high-RPM use on track as well as everyday road performance

Gearing Strategy for the CBR 1000 RR SC77

Selecting the right front sprocket tooth count is one of the quickest and most cost-effective tuning moves available to any CBR 1000 RR rider. A smaller sprocket (14 or 15 teeth) shortens the overall gearing ratio, sharpening acceleration and bringing the engine into its powerband faster — ideal for tight, technical circuits where exit speed out of slow corners is paramount.

Moving to a larger sprocket (16 or 17 teeth) lengthens the gearing, reducing engine RPM at a given road speed. This translates to higher top speed on faster circuits or motorway runs, and eases the engine at touring pace. With the Sitta N002, you can dial in the precise ratio your riding demands without compromising on component quality.

Build Quality

Sitta manufactures the N002 from chrome-molybdenum steel — the same family of alloy used in high-stress motorsport components — because the CBR 1000 RR SC77 produces the kind of torque figures that expose weakness in lesser sprockets quickly. The material's inherent toughness resists deformation under hard acceleration while its wear characteristics keep the tooth profile consistent over extended service intervals, protecting your chain investment at the same time.

Fitment and Compatibility

The Sitta N002 front sprocket is designed specifically for the following model:

  • Honda CBR 1000 RR SC77 — model years 2017, 2018, 2019
  • Compatible chain pitches: 520 and 525

Always verify your current chain pitch before ordering. Riders who have converted to a lightweight 520 kit will find the appropriate 520-pitch variant listed alongside the standard 525 option.
