– New Yoshimura Monkey 125 Exhaust Videos / Sound-Clips, Pictures + Dyno Chart HP / TQ Performance Increase Info! –

New aftermarket performance goodies are starting to finally trickle out for the New 2019 Honda Monkey 125!

Yoshimura is considered one of the best in the business when it comes to aftermarket exhaust systems for motorcycles whether it be a full exhaust or a slip-on for those that want the more cost-effective approach but still want to make a little more noise than the factory exhaust systems offers. The all-new 2019 Monkey 125 is going to probably end up with a slew of aftermarket part and accessory options for it just like the Grom did when it was first released back in 2013. Exhaust systems usually end up being one of the first modifications for a bike and I’m sure it’ll be the same with the Monkey as with the OEM exhaust on it, it is whisper quiet, think of the sound of a sewing machine and there’s a Monkey 125 for you.

2019 Honda Monkey 125 Exhaust Review: Yoshimura RS-3 Slip On Street System HP & TQ Performance Increase

For Yoshimura, getting the details right on the Monkey was critical. Sure we added performance. Our Monkey 125 Slip-On exhaust 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 hard anodized cap featuring a titanium tip, a special inner core baffle, and an integrated heat shield, this little guy delivers style, performance, tone and fun! Its all about the details on this new system for the new Monkey!

New Yoshimura Works Finish

The new Yoshimura Works Finish takes on a unique coloring after it goes through a heat cycle on the motorcycle that looks much like those titanium works components our factory racers use. Both the full exhaust and the slip-on for the Monkey 125 come with this new Works Finish from Yoshimura.

  • Contemporary Satin/matte finish
  • Uniform heat coloration
  • Increased fatigue strength
  • Increased scratch and stain resistance

How much of an increase in your top speed on the Monkey 125 will you see by adding an aftermarket exhaust? That’s still undetermined at the moment but I would anticipate it’ll be extremely close to what kind of gains I saw on my Honda Grom in the top speed department etc. You can check out more on my top speed increases as well as mods done by Clicking Here.
