$0.00
The Sport-Touring Kit is a great choice between our popular Sleeper and Muscle kits!
FOR 2017-2023 1st GENERATION M8
Developed for the experienced rider that wants touring reliability and the widest power curve in its class! The Sport-Touring kit matches our Stage II M8 headwork blueprinting with our Red Shift 548 camshaft and 4.25” cylinder kit that results in big power across the entire RPM range. Twist the throttle at nearly any RPM and you’re rewarded with immediate, seemingly effortless forward motion! The key to this great power is the carefully engineered combination of airflow, camshaft timing, compression, displacement and Zipper’s legendary commitment to testing and machining detail. All of these components are produced in-house at Zipper’s so you can be assured of the highest quality and reliable results!

Just wanted to give the guys at Zippers a shout out on their latest 124” kit. My shop Pure Hell Customs has been using Zippers products and services for over 20 years. This is a very impressive setup from the parts to the machine work! The power is amazing making 149tq and 138.8hp on our Dyno. Thank you Zippers!

This kit will turn your touring machine into a touring beast. Power throughout the entire RPM range, even in the low range. Cruises great and surges on demand. Power comes in smooth and builds on itself. I can’t say enough good things about this kit. Try one, you won’t regret it!

AMAZING results with the #517-986 Sport-Tour 128 Kit on my 2021 Roadglide 117. . . . I considered the 128 Muscle kit but chose the Sport Touring with 6 less HP but 4 more ft.lbs. torque. This engine is as tame as a factory stock engine when riding gently, but an absolute beast when I open it up. The torque comes on strong at low RPM and never lets up, and the fuel economy is over 40 MPG when I ride it sensibly. I’ve owned dozens of custom engine builds in 50+ years and never had such a perfect balance between rideability and performance. Anyone can build an engine that shows big numbers on a dyno sheet but is worthless in the RPM ranges we use every day. There’s no question these Zippers kits are the best in the industry.
