The choice of 14 to 17 teeth across both 520 and 525 chain pitches gives you genuine control over how your R6 accelerates, revs and pulls at the top end.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eChrome-molybdenum steel construction provides exceptional tensile strength and wear resistance, outlasting standard carbon-steel alternatives under sustained high-rpm loads\u003c\/li\u003e\n\u003cli\u003eHigh-precision machining ensures exact tooth geometry for smooth chain engagement and minimal drivetrain noise\u003c\/li\u003e\n\u003cli\u003eFour tooth counts — 14, 15, 16 and 17 — let you dial in gearing to suit track sprints or road touring without compromise\u003c\/li\u003e\n\u003cli\u003eAvailable in both 520 and 525 chain pitch, covering converted lightweight setups and standard factory configurations\u003c\/li\u003e\n\u003cli\u003eDirect OEM-pattern fitment to Yamaha R6 RJ11, RJ15 and RJ27 frames — no modifications required for installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eMaterial \u0026amp; Build Quality\u003c\/h2\u003e\u003cp\u003eChrome-molybdenum alloy steel sits at the heart of the Sitta M002's durability. This material is chosen specifically because its elevated chromium and molybdenum content resists surface fatigue and deformation under the repeated shock loads that a high-revving inline-four like the R6 generates at the countershaft. Compared to mild steel sprockets, the alloy holds its tooth profile far longer, preserving chain life and maintaining consistent power delivery throughout the sprocket's service life. The precision-cut teeth reduce chain wear and the risk of the pitch mismatch that causes premature stretching — a critical advantage if you run the R6 hard on track days.\u003c\/p\u003e\u003ch2\u003eGearing — Choosing the Right Tooth Count\u003c\/h2\u003e\u003cp\u003eSelecting the correct front sprocket tooth count is one of the most cost-effective performance adjustments available for the Yamaha R6. Understanding what each option does helps you make a purposeful choice rather than a guess.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e14 or 15 teeth: shorter overall gearing — the engine reaches peak torque more quickly in each gear, sharpening acceleration out of slow corners and tightening the power delivery feel. Ideal for tight, technical circuits or stop-start urban riding.\u003c\/li\u003e\n\u003cli\u003e16 or 17 teeth: taller overall gearing — the engine runs at lower revs for a given road speed, reducing mechanical stress and fuel consumption on motorways or high-speed circuits, and raising the theoretical top speed ceiling.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBecause the Sitta M002 is offered in both pitches, riders who have converted their R6 to a lighter 520 chain setup retain the same tooth-count flexibility as those running the factory 525 standard.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta M002 front sprocket fits the following Yamaha R6 generations directly:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha R6 RJ11 (2006–2007)\u003c\/li\u003e\n\u003cli\u003eYamaha R6 RJ15 (2008–2016)\u003c\/li\u003e\n\u003cli\u003eYamaha R6 RJ27 (2017–2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eChain compatibility: 520 pitch and 525 pitch.
