PERFORMANCE PLUS OUTFITTING THREE DIFFERENT MOTORCYCLES WITH NEW CAMS, EXHAUST, INTAKE, AND TUNER
You’ve heard the old chestnut: “Your motorcycle is just a down payment for the accessories.” This definitely rings true in V-twin land, especially in the horsepower and torque departments. Yes, factory motorcycles are perfectly fine, but we’re not fine with perfectly fine, are we? We want more! One common V-twin upgrade is a new exhaust system. But why stop there? There are so many more ponies to be gained from new cams and intake as well. And of course, given the technological advancements of
Harleys and Indians as of late, these upgrades require a fuel tuner to achieve proper air/fuel ratios. We picked three popular models to test the power packages we put together: 2018 Indian Chieftain Classic, 2018 HarleyDavidson Street Bob, and 2018 Harley-Davidson Road Glide. We then swapped out the factory suck-blow bits for new cams, pipes, intakes, and tuners and tested each on our dynamometer. Overall, we yielded some pretty nice gains. Hopefully our efforts aid in your search for selecting performance components for your bike.
