Sitta Aluminium Rear Sprocket for Ducati Panigale 899 & 959 (2013–2019) – Part 202D, 525 Pitch, 37–47 Teeth

Shaped from aerospace-grade aluminium and finished to a standard that looks as purposeful as it performs, the Sitta 202D rear sprocket is built specifically for the Ducati Panigale 899 and 959. Whether you are chasing lap times or refining road manners, this CNC-machined sprocket delivers precise power transfer, minimal drivetrain vibration and a colour palette that lets your drivetrain reflect your build.

Key Features

• CNC-machined from high-grade aluminium for an exceptional strength-to-weight ratio — just 350 g at size 45
• Dedicated 525 pitch fitment, tuned for the OEM drivetrain specification of the Panigale 899 and 959
• Eleven tooth options from 37 to 47 teeth allow precise gearing adjustment for track, road or mixed use
• Sprocket carrier interface: 100/124 mm, 5-bolt pattern for a direct, rattle-free fitment
• Hard-anodised finish option offers superior surface hardness and longer service life compared with standard anodising
• Eight colour choices — hard-anodised, black, red, blue, green, orange, gold and silver — for a distinctive drivetrain aesthetic

Design, Finish and Heritage

Sitta has been producing precision drivetrain components for competition and road use for decades, and the 202D reflects that accumulated knowledge in every detail. The tooth profile is machined to tight tolerances, ensuring each link of the 525 chain seats cleanly and releases without drag. The lightweight aluminium construction keeps unsprung rotating mass low, which translates directly into sharper throttle response and more communicative handling — qualities that matter enormously on a motorcycle as chassis-focused as the Panigale.

The hard-anodised surface treatment deserves particular attention. Unlike standard anodising, the hard-anodise process penetrates deeper into the aluminium substrate, producing a surface that resists abrasion under the sustained load of repeated chain contact. For riders who cover high mileage or run the 899 or 959 on track regularly, this finish is the practical choice as well as the visually striking one. The full colour range — from understated hard-anodised and black through to gold and silver — means the 202D can either blend into a factory aesthetic or become a deliberate visual statement.

Gearing Guide

Selecting the correct tooth count is one of the most accessible and effective ways to tailor a motorcycle's character to its intended use.

• Smaller sprockets (37–42 teeth): raise top speed and reduce engine revs at cruising pace — ideal for long circuits or motorway touring
• Larger sprockets (43–47 teeth): sharpen acceleration and improve agility out of tight corners — the preferred choice for short circuits and technical road riding

The eleven available sizes mean you can dial in the exact gearing ratio that suits your riding style and circuit, without compromise.
