Power. Bikers can never get enough. That’s why the first thing many riders do is swap out their stock air intakes and exhaust. It’s one of the easiest, quickest ways to boost horsepower and torque.

The Sturgis Buffalo Chip loves power. Why else would it hold drag races right down the middle of its amphitheater headed up by a guy named “Crazy John!”

The Chip’s love of power can also be seen in the Rock, Rumble & Rebellion bagger Kuryakyn built for them. This custom 2017 Harley Street Glide isn’t meant for simply cruising. It’s definitely got a performance bend to it.

For one, it’s already equipped with the new Milwaukee-Eight 107 claimed to put out 114 ft-lb. of torque at 3250 rpm. So what’d Kuryakyn do to squeeze even more power out of Harley’s new V-Twin? It followed the tried-and-true formula of swapping out its intake and exhaust.

The Kuryakyn Hypercharger ES got a fresh new look and a few performance tweaks. 

To get the Rock, Rumble & Rebellion bagger breathing deeper Kuryakyn threw on its new Hypercharger ES intake. While the Hypercharger has been a staple in the Kuryakyn repertoire for about 20 years, they’ve revamped the ES with a modern, edgy look. On the performance side, Kuryakyn states “An integrated electronic servo motor delivers precise RPM-based butterfly engagement. The all-new custom Kuryakyn-designed high-flow K&N filter delivers approximately 10% more airflow than previous models for improved CFM rating, and a new internal ‘stinger’ design on the end cap maximizes airflow to the throttle body.” Kuryakyn’s Hypercharger ES is scheduled to be available for Twin Cam/XL models this month followed by the Milwaukee-Eight in late June.

Providing even more punch is a set of Kuryakyn Crusher Maverick 4” Slip-Ons for the Milwaukee-Eight in black. You think this thing barked before, you should hear it now. And while the Maverick Slip-Ons are available to the general public, you’ll only find the Crusher One-Off Custom Headers on the Rock, Rumble & Rebellion Street Glide. To ensure that the new air/fuel ratios are dialed in just right and the bike’s running at peak performance, the Rock, Rumble & Rebellion bagger has been outfitted with a Vance & Hines Fuelpak FP3.
