Looking to replace my front & rear sprocket, along with my chain. 1st question, does dropping a tooth on my FRONT sprocket increase torque or top speed? - I know dropping teeth on the REAR increases speed, I'm just not sure if its opposite for the front. 2nd Question, Im looking around for a good replacement chain, around the 100 dollar mark. Is it better to spend the extra 20 bucks (120$) for the stock kawy chain? Its a 520 -DID DMA chain off the oem parts tree. Or should I look at another product? Specifically this one for 100 bucks- D.I.D 520 VX2 X Ring motorcycle Chain. Thanks!
