DescriptionThe whole story▼
A straightforward upgrade that rewards daily riders and weekend track-day enthusiasts alike, the Sitta 201M aluminium rear sprocket gives your Suzuki GSX-R 1000 a noticeable reduction in unsprung and rotating mass without asking you to spend beyond reason. Weighing just 350 g at 45 teeth, it slots directly onto the stock carrier and lets you fine-tune your gearing with a simple sprocket swap rather than a full drivetrain overhaul.
Key Features
- Lightweight aluminium construction — 350 g at size 45 — reduces rotating mass and sharpens throttle response on both road and track
- Wide tooth selection from 37 to 48 teeth in 520 pitch covers every gearing preference, from motorway cruising to tight circuit work
- Available in eight anodised colours — silver, black, hard-anodised, red, blue, orange, gold and green — the hard-anodised finish offering superior durability over standard anodising
- Carrier specification 110/130-6 bolt pattern ensures a precise, rattle-free fit and makes installation straightforward with standard workshop tools
- Precision-machined tooth profiles promote even chain engagement, minimising wear on both the sprocket and the chain
- Part number 201M — a well-established Sitta reference stocked for quick despatch
Gearing, Road Use and Track Use
Choosing the right tooth count is the single easiest way to tailor the GSX-R 1000's character to how you actually ride. Smaller sprockets in the 37-42 teeth range produce a taller overall gearing ratio: engine revs drop at a given road speed, top speed ceiling rises, and the bike feels more relaxed on long motorway runs. Larger sprockets in the 43-48 teeth range shorten the gearing ratio, delivering snappier acceleration out of slow corners and a more immediate, agile feel through technical sections — the configuration most track riders reach for when circuit lap times matter.
For mixed road riders who occasionally visit a circuit, a mid-range tooth count such as 42 or 43 typically offers a well-rounded compromise: adequate top-end for A-road riding and enough drive to make overtakes feel effortless. Because swapping a rear sprocket is a modest job, many GSX-R 1000 owners keep a second sprocket on the shelf for dedicated track days.
Build Quality and Finish
Sitta machines the 201M from high-grade aluminium chosen for its balance of tensile strength and low density. The standard anodised options — silver, black, red, blue, orange, gold and green — provide a durable surface layer that resists corrosion and light abrasion. The hard-anodised variant goes further: the electrochemical process penetrates deeper into the aluminium matrix, producing a surface hardness that measurably outlasts conventional anodising under the abrasive conditions of chain contact and road grime. If longevity between service intervals is your priority, the hard-anodised option is the practical choice regardless of colour preference.
Fitment and Compatibility
The Sitta 201M rear sprocket is designed and manufactured specifically for the following application:
- Suzuki GSX-R 1000 — model years 2009 to 2023
- 520 pitch chain only — confirm your chain pitch before ordering if you have already converted your drivetrain
- Carrier bolt pattern: 110/130 — 6 bolt
If you are running a 525 or 530 pitch chain in standard configuration, a chain conversion to 520 pitch is required before fitting this sprocket. The 520 pitch conversion is a popular upgrade on the GSX-R 1000 in its own right, saving additional rotational weight across the entire drivetrain.
