I recently upgraded my 2025 Low Rider ST with the ZARD slip-on, and wow—the difference is striking. First off, the fit and finish are top-notch. The silencer is handcrafted in Italy from AISI 304 stainless steel, with that chic anodized aluminum end cap and genuine ZARD steel badge. There's a real sense of premium quality in the details.
Installation was a breeze—no ECU remapping required, no fuss. Just a clean swap-in job that took under an hour and left me confident in my own oily-finger handiwork.
Power delivery? Immediate and noticeable. I opted for the racing version, which clocks in at just 3.3 kg—about 0.2 kg lighter than stock—and boosts performance by +3.1 hp. On the E5+ homologated variant, it’s only slightly heavier at 3.4 kg, but still delivers a respectable +1.9 hp gain.
But let’s talk sound—deep, rich, and confidently low without being over-the-top. That ‘unmistakable ZARD sound’ isn’t hype; it lives up to its reputation.
The whole experience—installation, performance, sound—felt like I’d just given my bike a soul injection. Even though it was an investment, seeing how much more responsive and alive my Low Rider ST felt afterward made it worth every cent.

When I first saw the ZARD slip-on for the 2025 Low Rider ST, I wasn’t sure what all the hype was about. But those doubts disappeared the moment it was in my hands. The craftsmanship is evident—stainless steel body, sleek anodized aluminum end-cap, and options in polished or Cerakote® black finishes give it a bespoke, high-end feel.
Installation? Smooth as butter. No ECU remapping needed, no weird adjustments—just a straightforward swap that took under an hour. When I fired up the bike, the difference was stunning. The racing version shaved nearly nothing off the weight but gave a whopping +3.1 hp boost. Even the Euro 5+ variant delivers a solid +1.9 hp, making every twist of the throttle noticeably sharper.
The sound—that rich, throaty ZARD tone—is unmistakable. Firm and confident, it commands attention yet remains refined. I’ve turned heads on the street without ever feeling like I’m going overboard."

Bottom line? The ZARD slip-on for my 2025 Low Rider ST isn’t just an upgrade—it’s a statement. Bold in design, precise in performance—completely worth the investment."*

Let me start with this: installing the ZARD Slip-On Exhaust on my brand-new 2025 Harley-Davidson Low Rider ST was one of the best upgrades I’ve made yet. From the moment I unboxed it, the craftsmanship was obvious—the stainless-steel body paired with that sleek aluminum end cap just exudes quality.

Installation was a breeze. The parts lined up with OEM mounting points perfectly—no grinding, no improvisation—just a clean, fast fit within about 45 minutes. Clear instructions, no guesswork.

Once it was on, the transformation was immediate. The bike is lighter—noticeably so—and comes alive with every throttle. The power bump is tangible; there’s the kind of surge that makes rolling onto the highway feel effortless, whether I’m doing a mellow cruise or leaning into a twisty backroad.

But what really captivated me was the sound. Deep, rich, and authoritative, it captures the iconic Harley growl without being obnoxious. It’s the sort of tone that turns heads, yet isn’t so loud that it rattles your nerves or settings. It’s just right.

Riding on longer trips has also been more comfortable. I’ve felt less residual heat radiating down into my legs—nice bonus for those warmer rides.

All in all, the ZARD Slip-On Exhaust brings the perfect blend of form, function, and that classic Harley soul. It’s a top-tier upgrade I’d happily recommend to any rider wanting more power, better sound, and a premium look
