DescriptionThe whole story▼
Machined from high-grade aluminium and finished to exacting tolerances, the Sitta 201M rear sprocket is a precision-engineered upgrade for the Yamaha R7 that rewards riders who refuse to compromise on build quality. Whether you are fine-tuning your gearing for a track day or optimising throttle response on a favourite road, this is the component that earns its place on the drivetrain.
Key Features
- High-grade aluminium construction delivers an outstanding strength-to-weight ratio — the sprocket weighs just 350 g at 45 teeth, keeping unsprung mass to a minimum.
- CNC-machined profile ensures precise tooth geometry and virtually vibration-free power transfer at all engine speeds.
- Available in tooth counts from 37 to 48, giving you genuine flexibility to dial in gearing for acceleration, top speed, or anything in between.
- Eight anodised colour options — including hard-anodised finish for exceptional surface hardness and durability beyond standard anodising.
- 525-pitch specification matched precisely to the Yamaha R7 drivetrain for a guaranteed fit every time.
- Sprocket carrier pattern: 110/130 — 5-hole, enabling straightforward, tool-accessible installation.
Build Quality and Materials
The 201M is produced from a high-strength aluminium alloy chosen specifically for its resistance to the cyclic loading that a rear sprocket endures. The material is light enough to benefit handling and acceleration while remaining stiff enough to resist tooth deformation under sustained hard use. Every sprocket leaves the CNC mill with consistent tooth profiles across all available sizes, so the engagement feel is identical whether you run 37 or 48 teeth.
The surface treatments on offer range from standard anodising — available in silver, black, red, blue, gold, orange, and green — to a hard-anodised finish that achieves a significantly harder surface layer. Hard anodising is the sensible choice for riders who cover high mileages or frequently ride in mixed-weather conditions, as the additional surface hardness measurably extends service life compared to conventional anodising.
Choosing the Right Tooth Count
Gearing selection has a direct impact on how the Yamaha R7 feels and performs. Selecting the right rear sprocket tooth count lets you tailor the motorcycle precisely to your riding style and the environment — road or circuit — without any other modification.
- Smaller rear sprocket (37–42 teeth): shorter overall gearing lowers engine revs at cruising speeds and raises top speed — ideal for high-speed circuits or motorway touring.
- Larger rear sprocket (43–48 teeth): taller overall gearing sharpens acceleration and improves agility out of tight corners — the preferred setup for technical circuits and spirited road riding.
The Sitta 201M range covers the full spectrum, so a single sprocket choice can transform the character of the R7 to suit your exact requirements.
Fitment and Compatibility
The Sitta 201M rear sprocket is designed and manufactured exclusively for the following application:
- Yamaha R7 — model years 2021 to 2026
- 525 pitch only — not compatible with other chain pitches
- Sprocket carrier: 110/130 — 5-hole bolt pattern
Always verify your chain pitch before ordering. The 201M is designed around the 525-pitch chain and will not fit 520 or 530 setups without additional modification.
