There’s nothing subtle about a Harley-Davidson® touring bike, especially a Milwaukee-Eight. And there’s nothing subtle about the ear-to-ear grin you can’t control every time you fire it up. That’s what Harleys are supposed to do. Of course, once you ride the “new” off it, it’s time to start figuring out how to up the torque, the horsepower and the classic Harley sound. It’s what you do – even to an already great engine platform.
There’s a lot of talk among touring bike owners about starting your upgrade at Stage I … if it’s worth the expense, if it really improves performance, and if your bike really needs to be modded so soon. Well, the answer depends on whether you really want a better running ride than you brought home. And yes, starting at Stage I upgrades is a must. Stage I is the performance foundation necessary before even thinking about Stage II upgrades and beyond.
Our best picks for a Stage 1 upgrade bundle for your Milwaukee-Eight Harley-Davidson include the following motorcycle performance parts, all of which can be purchased on our website in our Chrome Package or Black Package:
1. D&D 2-INTO-1 BILLET CAT EXHAUST
D&D has designed an impressive new exhaust system for your 2017-2019 Harley Milwaukee-Eight motorcycle. It’s specifically engineered to pump up the bike’s horsepower and low-end torque. This good-looking pipe system delivers a deep, throaty sound to your motorcycle, even at idle. Check out some of the additional features:
2. ARLEN NESS BIG SUCKER AIR CLEANER
The BIG SUCKER™ air cleaner Stage 1 kit is designed to fit all 2017 – 2019 Milwaukee Eight touring motorcycles. New technological developments resulted in new, patent-pending system design for a hidden breather backing plate. Each breather now includes O-rings at the heads and proprietary breather tubes that significantly increase airflow – and more air equals more power. The new system also takes care of a few common problems:
3. THUNDERMAX® WITH WAVE TUNE
The ThunderMax® system puts total control over your EFI back into your hands. It’s a stand-alone tuning system designed with proprietary Wave Tune AutoTune technology. It perfectly interfaces with your new wide-band O2 sensors that come with this ThunderMax tuner. While you’re riding, it automatically analyzes and adapts to an extensive range of throttle and RPM changes and positions. These automatic adjustments seriously increase your Harley’s performance. This award-winning system is manufactured in the United States and ready to install – no wire splicing or cutting required.
In addition to the ThunderMax® ECM, two wide-band oxygen sensors and a tuning cable are included in the kit. The tuning suite software allows you to monitor and/or adjust the following, including diagnostic codes, warm-up settings, ignition timing and more:
Your new ThunderMax tuner will adapt seamlessly with any future upgrades (Stage II, III and beyond) to your motorcycle, never being outgrown, and also never needs to be dyno-tuned. Your ThunderMax module is backed by a 3-year manufacturer warranty and unlimited manufacturer tech support.
Let’s face it … there’s a noticeable difference to starting with a stock bike and climbing onto a Stage I M8. Using the right motorcycle performance parts means a significant improvement in drivability, breathing, throttle response off the line, efficiency and sound. Stage I is just the beginning. Throwing more fuel and air at the cylinders is the most affordable way to bump up performance.
