JT Front Sprocket, Steel Rubber-cushioned, Style JTF404 (525)

Sprockets set your gearing. One tooth fewer at the front, or a couple more at the rear, makes the bike pull harder out of corners and lifts the front sooner, at the cost of top speed and higher revs on the highway. Going the other way calms it down. Worn sprockets have hooked or pointed teeth and will wear out a new chain quickly.

Fits BMW M/S 1000 XR, S 1000 R, S 1000 XR and S1000RR

• Computer-designed to achieve ultimate strength at minimum weight
• Sprockets are heat-treated and bead-blasted to reduce material surface tension
• Front sprockets are made with C45 steel and SCM415 chromoly steel alloy
• Rubber cushion used by the major Japanese motorcycle manufacturers since early 1990’s to dampen the chain impact on the teeth of the front sprocket
• Model-specific: check the fitment list for your bike

Every tooth count of this front sprocket fits the bikes above. Choose the stock count to keep your gearing, or a different one to change it.

Changing tooth counts changes your speedometer reading on most bikes, and may need a different chain length. Replace sprockets and chain together.
