I recently fitted the ZARD Slip-Ons "Alu" Exhaust on my 2020 Harley-Davidson Low Rider S, and the experience has been nothing short of transformative. From the instant shift in sound to the tangible improvement in performance, it's an upgrade any cruiser rider would appreciate.

Build & Aesthetics
These slip-ons are crafted from AISI 304 stainless steel, featuring striking conical shapes with visible MIG welds and sleek billet anodized aluminum end caps. I chose the polished finish—it gleams beautifully and adds a subtle, classy flair that perfectly complements the Low Rider's silhouette.
Weight & Handling
You really feel the difference—especially with the racing variant. At just 3.7 kg, it trims around 4.5 kg off the stock setup, lightening the ride and imparting noticeably sharper handling. Even the homologated Euro 4/5 version offers solid weight savings—3.9 kg and about 4.3 kg lighter than OEM.
Performance Gains
The upgrade isn’t just cosmetic. The racing version delivers an extra 1.5 hp, while the Euro 4/5 unit still offers a satisfying 1 hp boost—enough to feel more eager when winding on the throttle, especially at mid-range speeds.
Sound Profile
That deep, throaty ZARD rumble? Exactly what you'd hope for. It's robust and authentic—definitely assertive without veering into obnoxiously loud territory. It enhances the riding experience, adding an edge without draining your ear’s patience—even on longer cruises.
