Features include a split shaft design that is black zinc coated to prevent corrosion, and completed with a precision sealed roller shaft/bearing assembly. Factory bolt patterns, most units are fully compatible with stock components for easy installation, including cruise control.

Been catching up and resetting since Bike Night ⚡️ but we pulled off another fun, safe, exciting, packed and successful event! Tony & Charles had traffic running smoother than ever and reported that everyone was thankful and respectful throughout the night 👊🏻 The Concrete Cowboys, Eastcoastin’ Crew and Junkyard Kenny burned it down 💨 The Furthest Traveled winner was from Salt Lake City, UT 🏆 To our friends and family who help us year after year bring calm to the chaos during this busy week, we can’t thank you enough for all of your hard work! We love having this event, are proud of how much it’s grown over the years and proud to have some great, supportive people behind it with us. To everyone who came out, bought merch, gave to the Cali Foundation and donated to our friend, Hendo’s recovery, thank you ❤️‍🩹🫶🏻 Gasoline Alley has been a part of our lives and business for decades. We are happy to show you all some good, honest, community togetherness fun from the west side 🏁 Until next year 🤘🏻

The day is getting closer so here are a few more reminders about HPi Bike Night:

⚫️The only persons allowed to participate and perform any of the stunt show are the professional athletes we have asked and invited to do so. The stunt show will be set up in our parking lot barricaded for safety and not on the Street per the city of Indianapolis

⚫️The attendees that come to this event are here to see the professional stunt guys so please do not attempt these stunts yourselves

⚫️Please make sure you support and enjoy the Food Trucks, Serendipity Mobile Catering, Los Reyes Tacos, Dogs to Go by Uncle Zo and Kona Ice

⚫️Please make sure you support the stunt teams by purchasing their Merch and also the Vendors we will have on site, ThunderMax, Custom Dynamics and Porterbilt

⚫️The stunt guys always enjoy signing autographs and taking photos and there will be time to do this throughout the night

⚫️DJ Josh Hause will be helping us hand out the hourly swag bag give-a-ways and the award for “Furthest Traveled”

⚫️Cali Foundation will have some fun games for the younger crowd and items to raise money for children with cancer

⚫️The officers on duty as well as our own Horsepower staff will be parking, directing crosswalks and crowd managing

⚫️The main purpose of this event is to celebrate one of the most exciting weekends in our community with our industry. It brings people together from all over the U.S. and worldwide

⚫️We have local fire fighters, police officers and veterans who attend our event every year and we highly support and respect all of these individuals. Please help keep this event alive by cleaning up after yourselves and showing respect to your fellow neighbor. The event will end at 9pm sharp.

Thank You!
