Harley Stage 1 Upgrade Parts

When you are looking to upgrade your motorcycle’s performance, there is only one place where you should start. That place is at a Stage 1 upgrade. A Stage 1 upgrade consists of upgrading your Harley’s slip-on mufflers and air cleaner to ones that are designed for improved performance. The idea is to create a more free-flowing intake and exhaust, which in turn boosts the horsepower and torque that your HD mill can produce. These upgrades are almost always accompanied by a fuel mapping change as well.

Stage 1 upgrades are the most common performance modifications riders make for a couple of reasons. First, it is the best bang for your buck in terms of power per dollar. A performance air cleaner paired with performance tuned slip-ons can make a real dramatic difference in the amount of horsepower and torque your motor produces. And they are less expensive options compared to other performance upgrades. The second reason why the Stage 1 is so popular is because it can be done with minimal labor. Most home mechanics can do the job themselves. If you do have the shop do the job, the labor is much less compared to anything dealing with the internals of the motor.

Performance isn’t the only thing that can be upgraded with a Stage 1 kit either. You can dramatically change the style and sound of your Harley too. In addition to performance, aftermarket brands put a big emphasis on style with their air cleaners and slip-ons. You can make your bike stand out from all of the rest with these simple, eye-catching upgrades. Or you can choose components with an understated style to make your bike into a sleeper on the street.
