I recently installed the ZARD "Penta" Slip-Ons on my 2010 Triumph Street Triple 675, and I’m extremely impressed with the results. The fitment was perfect — no adjustments were needed, and the installation was straightforward. The design is sleek and sporty, giving my bike a more aggressive look without overdoing it.

The sound is where these slip-ons truly shine. At idle, there’s a deep rumble that gets the adrenaline going, and when you rev it, the growl is intoxicating. It’s loud enough to make a statement, but not so overwhelming that it’s uncomfortable on longer rides. The tone is perfectly suited to the character of the triple engine.

Performance-wise, the bike feels more responsive. The throttle is sharper, and it seems like the bike just breathes better. I didn’t need to remap the ECU, but the performance boost is still noticeable, especially in the mid-range.

If you're looking to enhance the sound, aesthetics, and performance of your Street Triple 675, the ZARD "Penta" Slip-Ons are an excellent choice. Worth every penny!
