 For Reference;

Original Equipment stock sizes as supplied from Yamaha is ;

2015-2017 YAMAHA FJ-09 OEM size is 525x110 X-Ring chain, 16t Ft. Sprocket, 45t Rear Sprocket

For QUICK ACCELERATION 15/45t gear ratio kit (off the line, roll on's, wheelies), use a 15t (-1t) front sprocket and a 45t Rear.

   (this is the default gearing that will be sent unless otherwise specified)

*Your top gear cruising rpm's will be higher, and your top speed will be lower with this quick acceleration kit.  -1t Front is versatile because you can switch back to stock gearing with a 16t sprocket and the same chain if you ever want to ..

For EXTREME QUICK ACCELERATION 15/47t gear ratio kit (crazy quick off the line, wicked roll on's, way easier wheelies), Request a 15t (-1t) front sprocket and a 47t (+2t) rear sprocket

Request this 15/47t EXTREME Q.A. combination at checkout. Your top gear cruising rpm's at 70mph will be MUCH higher than oem gearing. Top Speed will be MUCH lower. 

If you ever want to go back to a less radical gear ratio, you can always put a 16t front sprocket back on with the same chain length provided, and go back to stock gearing or regular quick acceleration kit.        

Original Factory Supplied OEM 16/45t  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 request OEM 16/45t sprocket sizes in this 520 kit.

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 +3t rear combination is EXACTLY the same as a +6t 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

Available Sprocket Sizes; 

JT  Ft. Sprocket also available in 520 x 15 or 16 teeth

JT  Rr. Sprocket available in 520 x  42, 43, 45, 47 teeth

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 X-Ring disperses the pressure and minimizes power loss.

1.5 to 2 TImes Longer Wear Resistance (Compared with Normal O-Ring) The X-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.

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