I recently upgraded my 2017 Bonneville T120 with the ZARD Slip-On Exhaust with OEM Catalyzer Kit, and the results have been nothing short of revelatory.

First things you notice? The weight—or the lack of it. The stock system weighed in at 14.3 kg, while the ZARD kit trims that down to just 7.7 kg—a lean, mean reduction of 6.6 kg (14.5 lbs). That translates into noticeably crisper handling and a more responsive ride that feels as if the bike shed some bulk and gained agility instantly.
Craftsmanship that makes you pause. Handcrafted in Italy using high-grade AISI 304 stainless steel, this kit maintains the OEM catalytic converter—so you stay street-legal, with none of the headaches. You get to choose from satin, mirror-polished, or Cerakote® black finishes, each accentuating the T120’s heritage charm with modern finesse.
Sound that speaks without shouting. The stock exhaust was polite and understated—great for blend-in neighborhoods, but missing soul. With the ZARD kit, warm growl at idle, assertive rumble under throttle—yet tasteful. It’s confident, not invasive, adding character every time I twist the throttle.
Install was refreshingly simple. This was purely bolt-on—no ECU fiddling, no tuning, and I was back on the road in under an hour.
Since the swap, every ride—from urban cruising to countryside sweeps—feels elevated. The bike now responds with precision, exhales with class, and commands attention with subtle authority. It didn’t just get an upgrade—it got soul.

I recently installed the ZARD Slip-On Exhaust Kit with OEM Catalyzer on my 2016 Triumph Bonneville T120, and the upgrade has been everything I hoped for. It’s the perfect solution for riders who want better sound and style while keeping the catalytic converter in place.

The build quality is outstanding. The slip-ons are beautifully finished, with a classic design that matches the T120’s vintage aesthetic perfectly. They look like they belong on the bike—sleek, subtle, and premium.

The sound improvement is immediately noticeable. It’s deeper and fuller than stock, with a rich tone that brings the 1200 twin to life. It’s not too loud, but it adds just the right amount of growl and presence to make the bike feel more engaging and responsive.

Performance-wise, the bike feels slightly more free-flowing, with improved throttle response and smoother midrange power. Since this kit retains the OEM catalyzer, it’s an ideal choice for riders who want an upgrade without diving into full system modifications or remapping.

Installation was straightforward. Everything fit perfectly, and the entire process took less than an hour. No tuning or additional parts needed—just a clean, simple upgrade that works.

If you're looking to enhance your Bonneville T120’s tone and character while keeping it street-legal and emissions-compliant, this ZARD Slip-On Kit is a fantastic choice.
