For reference; Original Equipment stock sizes as supplied from BMW ;

2012-2013 BMW S1000RR OEM size is 525x118 X-ring chain, 17t Ft. Sprocket, 45t Rear Sprocket

For QUICK ACCELERATION gear ratio kit (quick off the line, quick roll on's, easier wheelies),
Request a 16t front sprocket and a 45t rear for Q.A. gearing in "add message" tab during checkout.
(the 11 tooth front change will give your bike a much quicker gear ratio , but will reduce top speed and increase top gear cruising rpm's)

For EXTREME QUICK ACCELERATION gear ratio kit (crazy quick off the line, wicked roll on's, way easier wheelies),
REQUEST a 16t (-1t) front sprocket and a  45t (+1t) rear sprocket in the "add message" tab during checkout.
Request this 16/45t EXTREME Q.A. combination at checkout. Your top gear cruising rpm's at 75mph will be MUCH higher than oem gearing.
Top Speed will be noticeably lower. If you ever want to go back to a less radical gear ratio, you can always put a 520x17t front sprocket on with the same chain length provided, and still be quicker than stock. 17/45t is the same ratio as regular quick acceleration kit 17/45t.

Original Factory Supplied OEM size sprockets are the calculated "Happy Medium" of off the line acceleration, roll on's, and reasonable high speed engine rpm's with the least amount of compromise on either top end or low end acceleration. 520 size conversion (narrower, lighter chain and sprockets) does NOT affect final drive ratio, only changing number of teeth on sprockets actually changes gear ratio.
If you just want a lighter easier turning final drive components kit (lighter reciprocating mass), but are using your entire gear box ratio as it is from the factory, then OEM BMW S1000RR 17/45t sprocket sizes in this 520 conversion kit will be perfect. 17/45t is stock gearing on '12/13 BMW S1000RR.   This is the DEFAULT for this advertisement.

Teeth and Sizes Explained...
**   A -1t front sprocket change is EXACTLY the same ratio change as +3t rear sprocket change.
**   A -2t front sprocket change is EXACTLY the same ratio change as +6t rear sprocket change (Very Extreme change)
**   A -1t front and +2t rear combination is EXACTLY the same as a +5t rear only change with stock front sprocket.
**   A 520 size chain is approx. 2mm narrower than a 525 chain, and 4mm narrower than a 530 chain. Less mass equals lighter weight equals easier to spin, but the ratio (teeth size) change makes the big difference. The sprocket width matches the chain width where it rides on the sprockets, thus a 520 chain must use 520 sprockets, and a 525 chain must use 525 sprockets, etc...
**   RPE Motorcycle has chain and sprocket conversion kits available in 520 , 525 , and 530 sizes for most motorcycles.
** A larger rear sprocket number of teeth size requires a longer chain, however +1 or -1 tooth on the front sprocket only will use the same chain length
             Ft. Sprocket also available in 520 x 16 or 17 teeth
Stealth Rr. Sprocket available in 520 x (44t is back ordered) 45 teeth only
              Note: 46t or larger are special order (made to order in any color), which cost $40 more and add shipping time

Half the Power Loss (Compared with Normal O-Ring XW-Ring construction reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers’ modified O-Rings have squashed points that increase friction. The XW-Ring disperses the pressure and minimizes power loss.

1.5 to 2 TImes Longer Wear Resistance (Compared with Normal O-Ring) The XW-Ring’s six contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring.

XW-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain
