Sitta Aluminium Rear Sprocket Ducati Panigale V4/S/R (2025-2026) – 37-48 Teeth, 525 Pitch (212D)

Precision-machined from high-grade aluminium, the Sitta 212D rear sprocket delivers an exceptional strength-to-weight ratio for the Ducati Panigale V4, V4S and V4R — giving you the confidence to fine-tune your drivetrain without compromising a single gram of performance. Weighing just 350 g at size 45, this is a component built to the exacting standards that Ducati's flagship superbike demands.

Key Features

• High-grade aluminium construction keeps weight to just 350 g (size 45) while maintaining outstanding rigidity under sustained track and road loads.
• Available in tooth counts from 37 to 48, giving you precise control over acceleration and top-speed characteristics to suit your riding style.
• Eight anodised finish options — including a hard-anodised variant that outlasts standard anodising for superior long-term wear resistance.
• 525-pitch specific design: every dimension is optimised for the 525 chain standard, ensuring consistent power transfer and minimal drivetrain wear.
• Sprocket carrier pattern 76/100-5 hole for a direct, play-free fit and straightforward installation.
• Equally suited to track days, sprint circuits and high-performance road riding on the 2025-2026 Panigale V4 range.

Build Quality and Materials

Sitta manufactures the 212D from aircraft-grade aluminium, machined to tight tolerances that guarantee consistent tooth geometry across the full 37-to-48 tooth range. The surface treatment is where this sprocket stands apart from the competition: the hard-anodised option produces a layer of exceptional hardness that resists abrasion far more effectively than conventional anodising, preserving the sprocket profile and reducing chain wear even under the intense loads generated by the Panigale V4R's engine. The remaining seven colour options — black, silver, red, blue, orange, gold and green — are finished to an equally high anodising standard, delivering both individual style and meaningful corrosion resistance.

Gearing and Performance

Choosing the correct tooth count transforms how the Panigale V4 responds on both road and circuit. A smaller rear sprocket in the 37-to-42 tooth range lengthens the overall gearing, reducing engine revs at motorway speeds and raising the theoretical top speed — ideal for fast, flowing circuits or long open-road sections. Moving up to the 43-to-48 tooth range shortens the gearing, sharpening throttle response and improving drive out of tight corners for maximum acceleration. With twelve distinct tooth counts available, the Sitta 212D lets you dial in the exact ratio that matches your tyres, circuit layout or road-riding preferences without any compromise.
