Revolution Performance

Revolution Performance was founded in 2002 as a valuable source for Harley owners looking to get more power from their V-twin. They currently stock a decent sized product line, but it all began with a bolt-on big bore kit, much like what you see here before you. Here at Dennis Kirk, we love to add some aftermarket muscle to our Harleys. With this in mind, the decision to stock Revolution Performance engine parts was a real no-brainer.

Big big bore kits are a great way to improve your Harley’s performance. These kits do more than just add horsepower. They also decrease engine temperature and increase lifespan. These kits are easy to install and made right here in the U.S.A.

We carry a lot of parts in our selection, and sifting through them can be something of a chore. But, it doesn’t have to be that way. Rather than sift through them, trying to find the right fit, let us bring the right fit to you. At the top of the page, where it says “Find Parts Fast”, input your motorcycle’s year, make, and model, and we’ll present you with all of the products that will fit your bike. This can save you plenty of time and effort in your search, it’s worth trying!

If you have any questions, ask us! You can ask us any questions you might have about our products under the “Q&A” tab on the product description page. And that’s not the only way that we try to help our customers. We also offer free shipping on all orders over $89, leaving more money in your pockets. After all, you don’t want to pay for shipping, you just want to add power to your bike! We know the feeling all too well, and that’s exactly why you are in such good hands here at Dennis Kirk.
