Sitta Rear Sprocket for PVM Sprocket Carrier (201J) – 37-47 Teeth, 525 Pitch

Getting the most from a PVM sprocket carrier starts with a rear sprocket that is precision-made to match it — and the Sitta 201J delivers exactly that. Machined from lightweight aluminium, available in eleven tooth counts from 37 to 47, and offered in eight anodised colours, this is a practical, high-quality drivetrain component that works equally well on road and track without demanding a premium budget.

Key Features

• Lightweight aluminium construction keeps unsprung weight low — just 350 g in size 45 — improving handling response and reducing drivetrain stress.
• Eleven tooth options (37 through 47) let you fine-tune your gearing to suit your riding style, your bike and the roads or circuits you frequent.
• Dedicated 525 pitch ensures correct chain engagement and maximises sprocket longevity when paired with a matching 525 chain.
• 80/100 five-bolt carrier pattern fits PVM sprocket carriers precisely for a straightforward, play-free installation.
• Hard-anodised finish option offers significantly greater surface hardness and wear resistance than standard anodising — ideal for riders who cover high mileage or run aggressive acceleration.
• Eight colour choices — silver, black, hard-anodised, gold, red, blue, orange and green — so the sprocket can complement any livery rather than being an afterthought.

Dialling In Your Gearing

Choosing the right tooth count is the single cheapest way to change how your motorcycle feels to ride. With the Sitta 201J spanning 37 to 47 teeth in one part number, you have real flexibility without needing to source from multiple suppliers.

A smaller sprocket in the 37-42 tooth range shortens the overall gearing ratio, which reduces engine rpm at cruising speed and raises top speed — a useful tweak for motorway commuters or long-distance sport riders. Moving to the 43-47 tooth range lengthens the ratio, sharpening acceleration out of slow corners and making the bike feel more agile in technical sections. Either way, the part number remains 201J and the installation process is identical.

Build Quality and Everyday Reliability

Sitta machines the 201J from quality aluminium chosen for its strength-to-weight ratio. The tooth profile is cut to maintain consistent engagement across the full service life of the sprocket. The hard-anodised variant goes a step further: the electrochemical process penetrates the surface of the aluminium rather than simply coating it, producing a finish that resists wear, corrosion and chain abrasion far better than conventional anodising. For riders who want a longer service interval without moving to a heavier steel sprocket, hard-anodised is the sensible choice.
