Gearing — Staying Stock or Making a Change
This sprocket is 16 teeth, which matches the stock front sprocket size on all main fitment bikes. Running this sprocket with a stock size rear sprocket keeps your gearing identical to OEM.
If you want to adjust your gearing, here is what tooth count changes actually do in practical terms:
Going one tooth smaller on the front (15T) shortens your gearing — the bike accelerates harder through each gear, the engine revs higher at any given speed, and top speed is reduced. The effect is roughly equivalent to adding approximately two to three teeth to the rear sprocket. Most riders who make this change do it for more pull out of corners or a more aggressive street feel. It is a noticeable change.
Going one tooth larger on the front (17T) lengthens your gearing — the bike revs lower at cruising speeds, feels more relaxed on the highway, and acceleration from a stop is slightly softer. Riders who do a lot of highway miles sometimes prefer this for the lower cruise RPM. Neither change is right or wrong — it depends entirely on how and where you ride. Stock gearing is well matched for most street use on these bikes.
