It's here - the third generation Honda Grom. Back in 2013, we couldn't wait for the OG model to arrive on US shores and the newest version has us with equal anticipation.

With more compression, a 5 speed gearbox and new styling, the latest generation Grom promises even more fun both on the street and at the racetrack... Yoshimura is ready.

For styling, power and clearance we developed our renowned RS-9T to perform on the third gen Grom and the results are incredible as the new Grom responded like a champ. The Street Series Works Finish slip-on increases performance 11.1% max HP and 11.9% max torque! YEAH BABY!

We didn't stop there, we designed our RS-9T to offer more ground clearance and lean angle than the previous gen model. For the cherry on top we added a matte carbon fiber end cap and heat shield - Now your new Grom will love you forever!

If your serious - it's only Yoshimura. Proudly made in the USA!

    David T. ★★★★★

    Took a gamble on the slip-on design and honestly the stainless muffler finish is cleaner than the stock can, plus the matte carbon end cap adds a nice touch. Bolted right up to my Grom in about twenty minutes with zero fuss. The tone is deeper but not obnoxious, which is exactly what I wanted for da

    Jason ★★★★★

    The matte carbon fiber end cap looks way better in person than in the photos, and the stainless muffler gives it a clean, aggressive tone without being obnoxiously loud.

    Michael G. ★★★★★

    Bolt-on fit was spot on for my '23, and the stainless tips with that matte carbon end cap look way sharper in person than the stock can. Took maybe 20 minutes in the driveway, no cutting or fussing.
