ok i have a 2005 roketa 125cc pit bike/dirt bike. I was looking at getting a new sprocket for the front and rear to make it go faster than 30 mph. i would like to hit 45-50mph the front is 11 tooth and the back is 47, i was thinking of going for a 14 in the front and a 41 in the back. idk where that would get me in the mph, and i dont know what size or chain i have, i think its either a 420 or 428 since thats the size pit bikes use, thank you for all the help.
pit bike 125 cc chain size 420 or 428? and what sprocket do i need?
