Stage 1 on a Harley-Davidson is an upgrade to your bike for modifying the air filter, the exhaust system, and the fuel metering system to run as efficiently as possible. This will allow it to breathe the air freely, and, as a result, increase the power available.

An important aspect of the process is that upgrading one part without the others will not give the desired effect. A Stage 1 Upgrade also requires no internal engine modifications.
There are a few myths surrounding Stage 1/4 and Stage 1/2, but they’ll be best disregarded, as they’re a poor substitute for the real thing. While they are definitely cheaper, they do not provide anything like the performance increase that you are looking for.
If you have not come across the cheap alternatives, they will revolve around getting more air into the motor by drilling holes into the plastic air-filter backplate. They work on the assumption that the restriction is getting an air-to-air filter instead of getting air through the air filter into the engine.
