Sitta Aluminium Rear Sprocket for MV Agusta F3 675/800 (2012-2026) – 37-47 Teeth, 525 Pitch (201A)

Engineered to the exacting standards that the MV Agusta F3 platform demands, the Sitta 201A aluminium rear sprocket delivers a measurable reduction in unsprung weight while maintaining the structural integrity required for both circuit work and spirited road use. Available in tooth counts from 37 to 47 and a full palette of anodised finishes, it allows you to dial in the exact gearing your riding style calls for.

Key Features

• CNC-machined from high-grade aluminium, keeping weight to just 350 g at size 45 for improved agility and reduced drivetrain inertia.
• 525-pitch specification, correctly matched to the F3 675 and F3 800 drivetrain for precise, vibration-free power transfer.
• Sprocket carrier interface: 80/104 mm, 6-bolt pattern for a secure and straightforward installation.
• Eleven tooth-count options from 37 to 47 teeth, letting you tune acceleration, top speed, and engine rev range to suit road or track use.
• Eight colour/finish options — hard-anodised, black, red, silver, gold, orange, green, and blue — so the sprocket can complement your bike's livery.
• High wear resistance under sustained high loads, suitable for repeated track sessions as well as everyday sport riding.

Gearing Guide: Choosing the Right Tooth Count

Selecting the correct rear sprocket tooth count is one of the most cost-effective ways to reshape how your MV Agusta F3 feels on the road or circuit. Understanding the effect of each option helps you make a confident, informed choice.

Fewer teeth (37–42): A smaller rear sprocket raises top speed and lowers engine revs at cruising speeds, making it well suited to open circuits or motorway touring. Power delivery becomes more relaxed and linear.

More teeth (43–47): A larger rear sprocket shortens gearing, sharpening acceleration out of corners and improving responsiveness at low to mid revs. Ideal for tight, technical circuits or aggressive road riding where exit speed matters more than peak top speed.

With eleven increments available in the 201A, you can move up or down in single-tooth steps to find the precise balance between acceleration and top speed your riding demands.

Build Quality and Construction

The 201A is CNC-machined rather than stamped or cast, which ensures tight dimensional tolerances throughout the tooth profile and bolt-hole pattern. This translates directly into quieter, smoother chain engagement and reduced wear on both the sprocket and chain over time. The 6-bolt, 80/104 mm carrier interface is the correct specification for the MV Agusta F3 and requires no adaptation or modification.

Note: product images may show sprockets from a related Sitta model that is visually similar to the 201A but not identical. The 201A is the correct part for the fitment listed below.
