A -1t front sprocket change is the same ratio change as +3t rear sprocket change.A -1t front and +2t rear combination is the same as a +5t rear only change with stock front sprocket. A 520 size chain is approx. 2mm narrower than a 525 chain. Less mass equals lighter weight equals easier to spin. But the ratio (teeth size) change makes the real throttle response 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 and 525 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.
Sprocket also available in 520 x 14 or 15 teeth? Sprocket available in 520 x 37- 48 teeth (no 43t or 47t is available).

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.
