Hey guys I am a experienced rider but j am not really into after market parts. So I was wondering if putting a bigger sprocket on the rear axle where the chain goes on. If getting a sprocket with more teeth would give me a higher top end. I usually ride with a YFZ450 and wr450. And I am not really worrying about my acceleration just more speed to stay with them. My dad does not want me putting judge upgrades into th bike so something smallnlike this could help me. But j am also into RC cars, and j know changing gears can make it over heat. So would over heating be a problem? Thanks for the help and if there is something that j can change that is not really a upgrade please tell me. Thanks again
