A pro streetbike rider will increase his or hers rear stock sprocket by 20-22 teeth. Doing so will reduce the top end speed upwards of 40% plus. If your motorcycle is running a 520, 525, or 530 rear sprocket we can accommodate all of them. All our wheelie kits come with new front sprocket, rear sprocket and chain.
If you are a street stunter doing this for fun and do not want to lose so much top end speed as a pro stunt motorcycle rider does then just increase to 12-15 tooth size, you will only lose 25% plus depending on size of motor.
Pro Stocket calculation example: So what the calculation of a pro rider rear sprocket increase is for example. Stock is 42+20=62. Now you will buy a 62 tooth wheelie sprocket.
Street Stunt Rider Calculation Example: So what the calculation of a pro rider rear sprocket increase is for example. Stock is 42+12=54. You will purchase a 54 tooth wheelie sprocket.
