sportster open primary

An open primary on a Sportster motorcycle refers to a modification made to the bike's primary drive system. The primary drive system is responsible for transferring power from the engine to the transmission.

In an open primary system, the primary drive is exposed, which means that the outer cover and clutch assembly are removed. This gives the bike a more aggressive look and improves its performance by reducing weight and friction.

However, an open primary system also has some downsides. For example, it can be louder and produce more vibration than a traditional closed primary system. It can also be more difficult to operate and require more maintenance.

If you're interested in adding an open primary to your Sportster motorcycle, it's important to do your research and consider the potential drawbacks before making any modifications. It's also a good idea to consult with a professional mechanic or experienced rider to ensure that the modification is done safely and correctly.
