Sitta Aluminium Rear Sprocket for MV Agusta F3 675/800 (2012-2026) – 37-47 Teeth, 520 Pitch (201A)

A rear sprocket that earns its keep day in and day out: the Sitta 201A is CNC-machined from quality aluminium and engineered specifically for the MV Agusta F3 675 and F3 800, covering all model years from 2012 through 2026. Whether your F3 splits its time between weekend road runs and occasional track days, the 201A delivers smooth, vibration-free power transfer and a weight saving that is immediately noticeable — all at a price that makes upgrading a straightforward decision.

Key Features

• Ultralight aluminium construction — only 350 g at size 45 — reduces unsprung mass for sharper handling without compromising strength.
• CNC-machined for an exact, rattle-free fit on the 80/104 mm, 6-bolt sprocket carrier standard to the F3 platform.
• 520 pitch — the correct specification for both road-going and race-prepared MV Agusta F3 builds.
• Wide tooth selection from 37 to 47 teeth allows precise gearing adjustment to suit your riding style and circuit layout.
• Available in hard-anodised, black, red, silver, gold, orange, green, and blue — so the drivetrain complements the rest of your build.
• Resistance to wear under sustained high loads makes it equally suited to spirited road riding and regular track use.

Choosing the Right Tooth Count

Gearing has a direct and tangible effect on how the F3 feels beneath you, and the 201A range gives you genuine flexibility. A smaller sprocket in the 37-42 tooth range lowers the overall gearing ratio, raising top speed and reducing engine rpm at motorway pace — ideal if your F3 sees long open roads or fast, flowing circuits. Moving up to 43-47 teeth increases the overall ratio for stronger acceleration out of tight corners and a more responsive throttle in urban or technical riding. With eleven tooth options available, you can tailor the drivetrain precisely rather than settling for a compromise.

Build Quality and Everyday Reliability

Sitta manufactures the 201A from high-grade aluminium selected for the right balance between low weight and durability. The CNC machining process ensures every tooth profile is consistent, which means the chain seats and releases cleanly with each revolution — reducing wear on both the sprocket and the chain itself. The hard-anodised finish option adds a surface hardness that extends service life noticeably on sprockets that see frequent use. For riders who want a performance component that does not demand constant inspection or early replacement, the 201A is a sensible, long-term choice.
