DescriptionThe whole story

Sitta has spent decades supplying front sprockets to both road riders and race teams, and the N002 is a product of that accumulated knowledge. Machined from chromium-molybdenum steel and engineered to exacting tolerances, this front sprocket brings genuine motorsport heritage to every Honda CBR 600 RR built between 2003 and 2025 — whether you're chasing lap times or carving weekend roads.

Key Features

  • Chromium-molybdenum steel construction delivers outstanding wear resistance and long service life under high-load conditions
  • High-precision machining ensures a rattle-free fit on the Honda CBR 600 RR output shaft, with no shimming or modification required
  • Available in 14, 15, 16 and 17 tooth counts, covering both 520 and 525 chain pitches, so you can dial in exactly the gearing you need
  • Shorter gearing (14 or 15 teeth) sharpens throttle response and acceleration out of corners; taller gearing (16 or 17 teeth) raises top speed and reduces engine revs on long-distance runs
  • Consistent tooth profile maintains smooth, efficient power transfer throughout the sprocket's service life
  • Suits road, track-day and full race applications on the CBR 600 RR across the entire production span

Craftsmanship and Heritage

The Sitta N002 is not a generic catalogue part. Its roots lie in motorsport supply, where dimensional accuracy and material integrity are non-negotiable. The chromium-molybdenum steel alloy used here resists the combined stresses of high-rev power delivery, chain tension and heat cycling far better than mild steel alternatives. The finish is clean and precise — a telling sign of a component that has been produced with process discipline rather than simply cast to a rough outline and called done.

That heritage translates directly to confidence on the CBR 600 RR's famously peaky inline-four. A front sprocket that seats cleanly on the splined output shaft, holds its geometry under load and wears evenly does more for drivetrain efficiency than almost any other single component change. The N002 delivers all three.

Choosing the Right Gearing

Front sprocket tooth count has a disproportionate effect on overall gearing because even a one-tooth change at the front is equivalent to a three-to-four tooth change at the rear. The N002's four tooth options give you real flexibility:

  • 14 or 15 teeth: shorter gearing for stronger acceleration, more aggressive engine character and faster-revving response — ideal for tight, technical circuits or urban riding
  • 16 or 17 teeth: taller gearing for relaxed motorway cruising, a higher potential top speed and reduced engine wear on long-distance routes

Pair with a matching 520 or 525 rear sprocket and chain for a fully optimised drivetrain.

Fitment and Compatibility

The Sitta N002 front sprocket is designed specifically for the Honda CBR 600 RR across the full production run from 2003 to 2025. Both 520 and 525 chain pitch variants are available, allowing fitment to standard-spec machines and to bikes that have been converted to a lighter 520 chain kit.
