Looking for a little more speed out of your motorized bicycle without sacrificing torque? The 40 Tooth Sprocket is made to give any 2-stroke engine or 4-stroke bike engine a boost of speed without bogging down on hills and inclines as smaller sprockets do.
This rear wheel sprocket is ported with 9 holes to fit nearly any motorized bicycle engine kit’s sprocket clamp assembly. It’s also made of lightweight metal and creates extra top end speed with a slight increase in acceleration response.
If you’ve got all the high-performance parts you can think of but you still can’t get that bit of speed you’re looking for, this 40 Tooth Motorized Bike Sprocket is what you need for the ultimate bicycle engine.
