DescriptionThe whole story▼
Engineered specifically for the Sitta Quick Fit Rear Sprocket Hub (266D), this aluminium rear sprocket slots cleanly into the single-sided swingarm architecture of the Ducati Panigale family, giving you a precise, rattle-free fit that remains comfortable to live with across long days on road or track. Choose from ten tooth counts spanning 37 to 46 and two pitch options — 520 or 525 — to dial in exactly the gearing character you want without compromise.
Key Features
- Hard-anodised aluminium construction keeps unsprung and rotating mass to a minimum, sharpening throttle response and reducing rider fatigue on extended rides.
- Ten tooth-count options from 37 to 46 teeth let you fine-tune gearing for everything from tight club circuits to open-road touring without changing the hub.
- Compatible with both 520 and 525 pitch chains, giving flexibility whether you are running a standard 525 set-up or have converted to a lighter 520 chain kit.
- Dedicated fitment for the Quick Fit Rear Sprocket Hub (part number 266D) means installation is straightforward and alignment is guaranteed.
- Hard anodising resists corrosion and surface wear, extending service life even under repeated track sessions and wet-weather road use.
- Designed around the Ducati single-sided swingarm geometry for a factory-clean appearance with no adapters or spacers required.
Performance on Road and Track
Reducing rotating mass at the rear wheel is one of the most cost-effective ways to improve the feel of a Panigale. A lighter rear sprocket means the engine spends less energy spinning components and more energy accelerating the bike, a difference you notice most when picking up speed out of tight corners. The hard-anodised finish on this Sitta sprocket holds up under the sustained heat and grit exposure that track use generates, so the teeth retain their profile across a full chain service interval rather than wearing prematurely.
On the road, the ability to select from ten tooth counts makes it easy to soften gearing for motorway miles or sharpen it for a more responsive, short-gearing feel on mountain passes — all while keeping the same hub and wheel in place.
