A ratio that is too long may prevent you from taking full advantage of the engine’s power, and one that is too short can have the same effect. Normally, you should follow certain guidelines to choose them. \u003cbr\u003eIn the case of the sprocket, it is completely different: if it has \u003cstrong\u003emore teeth\u003c\/strong\u003e, it results in a shorter ratio (higher RPM), whereas if it has \u003cstrong\u003efewer teeth\u003c\/strong\u003e, it lengthens the ratio (higher top speed).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eValid for the following models:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e- \u003cspan data-sheets-value=\"[null,2,\" rr vel\u003e), RR SUPERMOTARD, RJ SPIKE.
