A smaller sprocket shortens your overall gearing, raising top speed and reducing engine revs at motorway cruising speeds. A larger sprocket lengthens the gearing ratio, sharpening initial acceleration and mid-range punch — an advantage on technical circuits or twisty mountain roads where drive out of slow corners matters most.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e37–42 teeth: taller overall gearing — more top speed, relaxed cruising revs, ideal for fast open circuits and motorway touring\u003c\/li\u003e\n\u003cli\u003e43–48 teeth: shorter overall gearing — stronger acceleration, more responsive throttle, suited to tight technical tracks and spirited road riding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConstruction and Finish\u003c\/h2\u003e\u003cp\u003eEvery Sitta 202P sprocket is machined from high-grade aluminium billet, keeping rotating mass low without sacrificing the tensile strength needed to cope with the RSV4's considerable torque output. The hard-anodised variant takes durability a step further: the treatment penetrates the aluminium surface to create a hardened outer layer that resists wear, corrosion, and chain abrasion more effectively than conventional anodising. For riders who want a balance of personalisation and protection, the full colour range — silver, black, red, gold, blue, orange, and green — is anodised to a consistent, chip-resistant standard.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis sprocket is designed exclusively for the following models and is compatible with 525 pitch chains only:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAprilia RSV4 (2009-2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 R (2009-2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RR (2009-2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RF (2009-2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 1100 Factory (2009-2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eImportant: this sprocket is produced exclusively in 525 pitch.
