FOR SUPER NINJA ONLY!! DOES NOT WORK ON ANY OTHER SUPER BIKE (X1, X2...)
This sprocket is bigger than the stock 45 tooth the super ninja ships with. It gives more bottom end. The scooter will be faster off the line and pickup will be improved after turns, the top speed will not be as high (about 2 or 3 MPH slower). The 50 tooth sprocket is a good compromise and will give you better overall performance.
Install this sprocket if you want your scooter to pickup speed faster or if you have ported your engine and want to get the most performance out of it.
Installation difficulty 6. The reason this part is difficult to install is that in most cases, the chain needs to be extended with 4 or 5 additional links.
