*System shown is a Pre-Production. Production systems will come with a matte carbon fiber end cap and heat shield.

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!

    Awesome upgrade!

    If your not looking to utilize the full exhaust but want your bike to be heard. this slip on is what your looking for! I was totally satified with this slip-on for the exhaust! Sounds so much better than it sounding like a quiet Scooter.
