Hypercharger ES for 2018 Softails
Last year saw Somerset, Wisconsin based Kuryakyn launch a major update for its famous Hypercharger - now it has announced the awaited 2018 M-8 engined Softail application.
The iconic air cleaner has a 30-year pedigree and the ES version is a step change. It preserves the signature hot rod blower styling but “represents substantial updates in design, technology and performance,” according to the company.
“The state-of-the-art electronic throttle response butterflies eliminate vacuum-triggered fluttering. An integrated servo motor syncs with the coil to actuate and open the butterflies for smooth, precise movement with every twist of the throttle.
“Air delivery is maximized through the Kuryakyn designed high-flow K&N filter, featuring a larger surface area compared to the original Hypercharger. The larger filter element offers approximately 10% more airflow, improved CFM rating, and utilizes a unique end cap with internal stinger design that directs concentrated airflow into the throttle body.
Kuryakyn says that independent dyno testing performed by St. Croix Harley-Davidson (New Richmond, Wisconsin) resulted in added horsepower and more than six additional ft. lbs. of torque throughout the power band on a stock 114 ci Milwaukee-Eight Heritage Softail. Previous dyno testing performed on a stock 107 ci Milwaukee-Eight Street Glide by Those Dyno Guys (Zimmerman, Minn.) produced an 8.5 percent increase in horsepower and 3 percent more torque.
The die-cast A380 aluminum housing is offered in three finish options. The modular housing allows for easy customization with available classic faceplate kits (sold separately), featuring a fluted design that completely alters the style in minutes.
Additional fitments for Milwaukee-Eight Touring and Twin Cam Dyna, Softail and Touring models are already available, with Sportster applications expected soon.
The new gloss black Precision engine covers, also seen here, are described as taking the “blacked-out M-8 vibe even deeper into the dark side.”
Newly available in smooth gloss black, Precision covers “serve as an extension of the Milwaukee-Eight’s design language, enhancing the sinister look of Harley-Davidson ‘Special’ and CVO Touring models. The modern and muscular designs deliver a truly defined appearance for a seamless integration with every factory component, whether used individually or as a complete set, says Kuryakyn.
“Everything in the Precision line is bolt on, creating a uniform aesthetic with the motor. The collection includes groupings of unique covers and accents that bring the same powerful appearance to often overlooked areas of the engine and transmission. Focus areas include the cylinder base, inner primary, tappet block, transmission and starter, as well as the voltage regulator, oil cooler and coolant pump for liquid-cooled models, among others.”
Coming soon, full kits for 2018 Softail models will be offered in both gloss black and chrome finish options.
