About TB Parts Full Exhaust for Honda Monkey 125 - (Carbon Fiber, Matte Black or Polished Alum)
The new Monkey 125 Performance Exhaust was developed for performance, looks, and value. It is available in 3 choices: Carbon Fiber, Matte Black or Alum. There was an alternative needed to the massive size of the stock and most aftermarket exhausts. This exhaust on the popular Z50 (the original “Monkey”) aftermarket performance exhausts that has been selling for nearly 20 years. They increase performance while providing a clean and compact look that better fits the small Monkey in our opinion. It will fit perfectly, sound great, and improve the performance of your Monkey at a reasonable price for a quality exhaust. Some of the key features are:
  • Carbon\Matte\Alum Muffler Options
  • Chromed Stepped-up Header
  • Black Guard on Matte Muffler Option| Chrome Guard on Alum and Carbon Option
  • Does not require ECU flashing/tuning (but doing so would add additional performance)
  • Weighs 4.2lbs (stock is 11 lbs)
  • Includes a removable silencer
  • Works great with stock engines or ones with big bore kits
  • **** Important Note for 2022 & Up models: The exhaust fits perfectly on the new 5 speed engine, however, the clutch cable hits or is a couple millimeters from the exhaust so the heat could damage the cable.  The easiest solution to resolve this issue is to zip tie the cable to the frame and there are 2 perfectly located holes in the frame to make this a quick and easy fix (if you scroll thru the pics, we included one showing where the zip ties go). Alternate solutions are to bend back the clutch cable bracket on the clutch cover slightly or add some exhaust tape to the header pipe (it wont be visible as the location is behind the exhaust cover). ***
*Dyno runs were done by a shop (McNew’s Cycle Tuning, Dillsburg PA).  The first one pictured was done on a brand new (unmodified engine) Monkey.  The second one was done with the new exhaust with the silencer inserted and the third one without the silencer.  No ECU flashing/tuning was done or needed (but would add more performance if done).  If using with other performance products like cams or big bore kits, ECU flashing/tuning will be needed.

    Awesome sound easy to install, put this exhaust on and a 14 tooth sprocket on a stock engine and it came alive didn’t have to get a tuner as I didn’t modify the intake, that may come later just because it is priced lower doesn’t mean it is low quality, I love it

    Installing the stainless on my 2019 red Monkey last night. Easy install. Looks great. Love the sound! Priced ridiculously cheap, too.

    Love the look and style, but hate the sound. Yes, it’s a 125cc… but it sounds so wimpy with this exhaust. I’m guessing it’s the smaller diameter piping. But, for the price, it’s not horrible.

    This is a good quality exhaust system And the price is half of the other brands. He won’t be disappointed with this exhaust it sounds great and easy on the pocketbook.
