1045 Carbo Steel.
Increased performance without engine mods!
It reduces the tooth count from 33 to 31
Quicker launch
Better roll on acceleration
Stay in the "sweet spot" RPM range during slower riding speeds 7 % RPM differential in 6th gear
The purpose of underdrive gears is to multiply the torque delivered by the engine and transmission. Gears can be thought of as complex levers. In other words, they provide a mechanical advantage that multiplies work—in this case, torque—to help the engine’s power move the vehicle. Lower gears are like a longer lever: They provide more mechanical advantage. Higher gears are like a shorter lever: They provide less mechanical advantage. It’s similar to when you use a long breaker bar instead of a short ratchet handle to remove tight lug nuts. Just like a long bar puts more torque on a lug nut, lower drive gears provide more torque to the wheels.
The heavy bikes benefit most from this part, especially those running the VM-1 cam profiles as they give up a little bottom end TQ for the upper end HP increase. RPMs will increase with this pulley (EX: 3000 is now approx 3210 in 6th gear)

Just installed this gear on my 12 Hammer 8-Ball, 106 with S&S intake, Lloyds cams, Freedom Performance straight pipes, and tuned on Maximus. It was a beast with the stock gearing, just took a second to get above 3500 RPM and start ripping. Now it's effortless and it runs like a Raped Ape. I did notice that taking off has become a bit more touchy, you can't rev it and dump the clutch without the back tire spinning it's ass off, even with moderate throttle. BUT, get her rolling and then stand on it and 6500 RPM shows up in a hurry followed shortly thereafter by 100 MPH and climbing. Need to get the launch figured out better, only one ride after installing it tonight but the bike feels effortless in acceleration, like it lost 500 lbs of weight. Cruising RPM is up approx 3-400 RPM as expected but not really noticeable. Hands down one of the best Bang for you Buck you can get! This is a high quality steel gear, I have no worries about anything with it ever. Thanks Scott for running another batch of these, couldn't have been more happy with it than I am!
