As a long-time Trident 660 enthusiast, I couldn’t resist upgrading with the ZARD Exhaust Full Kit, and the results have been stellar. First off, the sound—it’s deep, bold, and raspy in the best possible way. It completely transforms the riding audio experience, giving the bike a musical growl that turns heads.
What truly impressed me was the weight reduction. My stock system weighed roughly 8.1 kg, while the ZARD kit dropped that down to about 3.6 kg—shedding nearly 4.5 kg off the tail end of the bike! The difference in handling is noticeable: sharper steering, lighter feel, and a more responsive ride.
Installation was fairly straightforward—no ECU flash needed—but be aware: fitting the rear mounting point was a bit of a tight job. I had to maneuver the bracket while loosening bolts, and I also routed the O₂ sensor cable under the oil pan and wrapped it for heat protection. Minor hassles, but worth the final fit.
As for performance gains, dyno numbers show a bump: stock made around 76.8 hp at 9,791 rpm, but with the ZARD kit, that climbed to 82.7 hp at 9,730 rpm. Torque also edged up a bit. These gains may not blow your socks off, but combined with the weight savings, the overall improvement is very noticeable.
A couple of caveats: some users have reported more popping and sputtering during deceleration—possibly due to a slightly lean condition—so you may want to monitor that or consider a remap.

I recently installed the ZARD Exhaust Full Kit (racing version) on my 2023 Triumph Trident 660. From the moment I fired it up, the deep, throaty roar completely transformed the riding experience—gone is the polite hum of stock, replaced by an aggressive burble that puts a grin on my face every time. The weight savings are mind‑blowing: this kit drops nearly 4.5 kg off the bike, bringing it down to just 3.6 kg total—that’s almost a 55% reduction compared to stock—making the bike feel remarkably lighter and more agile in tight corners.
Craftsmanship is top‑notch: AISI 304 stainless‑steel construction, optional titanium sleeve, and a carbon‑fiber end cap—all handcrafted with precision. It looks as fierce as it sounds, with a clean, muscular profile that complements the Trident’s styling beautifully. Installation was surprisingly straightforward—no structural modifications needed—though fitting was snug, especially near the rear mounting point; a bit of patience and slight repositioning did the trick
One heads‑up: if your bike is E5 Plus (emissions sensitive), installing this kit may trigger a "cat warning" on the dash due to catalyst detection quirks. It doesn’t affect performance, but it can be distracting. ZARD offers a dedicated UpMap ECU to correct this and eliminate the warning light—well worth considering if you want a clean setup
Overall, this isn’t just an aesthetic or auditory upgrade—it’s a performance enhancer that sharpens the riding feel dramatically. Sure, it’s a premium price, but the sound, the weight loss, the look—all of it feels worth every penny.

I recently installed the ZARD Exhaust Full Kit on my 2022 Triumph Trident 660, and wow—what a transformation. First thing I noticed is the dramatic weight loss: this 3‑into‑1 system sheds about 4.5 kg (10 lbs), cutting the original 8.1 kg system to just 3.6 kg. That’s nearly a 55% reduction, and you feel it in the bike’s agility and everyday handling.
The craftsmanship is top-tier: AISI 304 stainless steel construction, with optional titanium sleeve, topped with a carbon‑fiber end cap and heat shield. Sleek, sporty, and built to last—especially the satin or black finishes.
On the sound and performance front, ZARD’s dyno data aligns with my riding impression: stock setup makes about 76.8 hp, while the ZARD kit boosts it to around 82.7 hp, with a modest torque uptick from 63.7 Nm to roughly 65.7 Nm.
Throttle response is sharper, acceleration feels snappier—and the exhaust emits a deep, bold rumble that’s just intoxicating.

Installation did take some finesse. Based on users’ shared experiences, the rear mounting point is tight, and the O₂ sensor cable needs careful routing—some folks even ran it under the oil pan and wrapped part of the pipe for protection. A bit of patience and elbow grease were essential, but nothing a weekend of careful tuning can’t handle.

Heads-up: if your Trident is in E5 Plus spec, expect to get a catalyst‑warning light on the dash—it’s purely informational and doesn’t affect ride quality. An ECU remap or ZARD’s “UpMap” can neutralize that light and even squeeze out a bit more refinement.

I finally took the plunge and installed the ZARD Full Exhaust Kit on my 2023 Triumph Trident 660, and I couldn’t be happier with the result. First off, the weight reduction is astonishing—the system drops your bike’s exhaust weight from about 8.1 kg down to just 3.6 kg, shaving off around 4.5 kg. The difference is immediately noticeable when flicking the bike from side to side—it feels nimble, responsive, and much more planted in the corners
Visually, the build quality is top-notch: AISI 304 stainless steel with the option for a titanium sleeve, paired with a carbon-fiber end cap, gives the Trident a sleek, aggressive upgrade that turns heads. The satin or black finishes enhance the bike’s muscular silhouette
Performance-wise, ZARD’s dyno numbers are definitely persuasive: I got a noticeable bump—from 76.8 hp stock to about 82.7 hp, and torque rose slightly too, from 63.7 Nm to roughly 65.7 Nm. While it may not feel like a massive power surge, the combination of decreased weight and upgraded flow makes throttle response sharper and riding more engaging
The sound is arguably the most satisfying upgrade: a deep, bold resonance with a satisfying rasp that gives the Trident a more aggressive, thrilling voice—exactly what I wanted
On the installation side, fair warning: users have noted (and I can confirm) some challenges with fitment—particularly a very tight rear mounting point and routing the O₂ sensor wire safely (routing under the oil pan and wrapping it for protection is a smart move). I spent a bit more time than expected, but patience fixed every issue.

One more technical note: for the US Euro5‑Plus Trident models, installing this exhaust may trigger a “catalyst anomaly” warning light. It doesn’t affect performance, but if you prefer a clean dashboard you may want to consider an ECU remap
