After upgrading my 2020 Harley-Davidson Road King Special with the ZARD Slip-Ons "4.5 Inches" Exhaust, I can confidently say this is a royal treatment. Crafted in Italy from premium AISI 304 stainless steel, each pipe exudes quality—complete with precision billet anodized aluminum end caps and the stylish ZARD nameplate. It’s a clear blend of badass performance and tasteful design.
Fit & Finish:
These slip-ons are tailor-made for the Road King Special (2017–2024), and the fitment was seamless—bolt-on simplicity at its best. Nothing forced, nothing altered—I slapped them on and they clicked into place like they were born to be there
Performance Variants:
I went with the Racing version—9.5 kg and a solid +2.3 hp gain. There's also the street-legal Euro-5 homologated version at 9.8 kg with a +1.2 hp boost, if that’s more your style.
Sound & Feel:
At idle, it rumbles with an authoritative purr—like the King has woken and is ready to rule the road. Open the throttle and the pipes unleash a deep, guttural growl: aggressive without being harsh, refined yet undeniably powerful.
