Customer Reviews (4.8 / 5 · 5 reviews)

Joshua ★★★★★

Installed this on my R-55 and the sound level dropped just enough to be comfortable for residential areas. The kit fit perfectly and included everything needed for a quick swap.

Mia ★★★★★

The insert kit was straightforward to swap in, and the decibel reduction was noticeable right away on the first startup. Fits perfectly with the R-55 muffler and gives just the right sound level for my needs.

Christopher ★★★★★

Finally got around to installing the low-volume insert on my R-55 and the decibel drop is exactly what I needed for quieter neighborhood rides. The included hardware made swapping it out a clean, 15-minute job.
