Without a doubt one of the most anticipated new bikes for 2019 is the Honda Monkey. Using a platform of the best-selling Grom, Honda added in a slew of cool new retro styled fun and the Monkey is sure to bring miles of smiles.

For Yoshimura, getting the details right on the Monkey was critical. Sure we added performance. Our Slip-On system max HP is up 7.2% as well as max torque being up 2.9%, but the sound had to be fitting for the new two-wheeled primate - enter the custom developed pint-sized RS-3. With a custom a high temperature ceramic coated end-cap featuring a titanium tip, a special inner core baffle, and an integrated heat shield, this little guy delivers style, performance, tone and fun! It's all about the details on this new system for the new Monkey!

Proudly Made in the USA!

Ellie Q. ★★★★★

The deep, mellow tone when I rev it is exactly what this little bike needed—way better than the stock sewing machine sound. The stainless muffler looks killer against the chrome fender and feels solidly built. Install was straightforward too, no drilling or cutting.

Grace U. ★★★★★

The stainless finish on this slip-on really pops against the bike’s dark frame, and the exhaust note is deep without being obnoxious. Install took me about 30 minutes, and I love how it transformed the Monkey’s character.

Miles ★★★★★

Install was straightforward, but I did need a second set of hands to line up the hanger bolts. The deep note at idle is exactly what I was hoping for, and it wakes up nicely above 5,000 rpm without being obnoxious on the highway.
