DescriptionThe whole story▼

A reliable drivetrain starts with a sprocket that fits perfectly and holds up ride after ride. The Sitta 207Y aluminium rear sprocket is precision-machined for the BMW S1000RR K67 (2019–2026), available in eleven tooth counts from 37 to 47 and eight anodised colours — giving you genuine gearing flexibility at an accessible price point, whether you use the bike daily or at the weekend.

Key Features

  • Precision-machined aluminium construction delivers a strong power-to-weight ratio without excess cost
  • 525-pitch compatibility ensures direct fitment with standard and upgraded chain sets on the S1000RR K67
  • Eleven tooth options (37–47) let you tailor acceleration and top-speed characteristics to suit your exact riding style
  • Five-bolt sprocket carrier interface (119 x 140 mm, 12.50 mm bolt hole) guarantees a precise, wobble-free fit
  • Hard-anodised finish option offers superior surface hardness and extended service life compared to standard anodising
  • Eight colour choices — silver, black, hard-anodised, red, blue, orange, gold and green — so the sprocket matches your bike's look

Build Quality and Everyday Value

Sitta manufactures the 207Y from quality aluminium chosen for its combination of light weight and resistance to the sustained loads a high-revving litre-class superbike generates. The tooth profile is cut to close tolerances so chain engagement stays clean from the first ride, reducing the uneven wear patterns that shorten chain life prematurely. For riders who cover a mix of commutes, touring and occasional track days, this is a sensible, cost-effective upgrade over OEM — easy to swap during a routine chain-and-sprocket service and available in enough colour options to suit any livery.

Choosing the Right Tooth Count

The tooth count you select changes the effective gearing of your S1000RR in a predictable way, and with eleven options there is a meaningful choice for every use case.

A smaller sprocket (37–42 teeth) raises overall gearing, reducing engine speed at motorway cruising pace and nudging the top speed ceiling higher — useful for extended road riding or long straights on track. A larger sprocket (43–47 teeth) shortens the gearing, sharpening throttle response out of slow corners and improving drive off the line, which suits tight, technical circuits or urban riding where acceleration matters more than outright speed. The stock tooth count is a sensible baseline; moving one or two teeth either side produces a noticeable but manageable change.

Fitment and Compatibility

The Sitta 207Y is designed and manufactured exclusively for the following model:

  • BMW S1000RR K67 — model years 2019 to 2026
