CT70 K1–1982 Black & Chrome Stock-Style Exhaust – 125cc Fitment
Couldn't load pickup availability
Classic factory look. Simple, quiet, and built for rider setups.
This exhaust is styled after the original CT70 K1–1982 unit, finished in black with a chrome heat shield for that clean OEM appearance. It’s a budget-friendly option that works especially well on 125cc horizontal engine builds.
This is not a high-flow race pipe — it keeps a quieter, stock-style tone and clean factory profile.
Engine Compatibility:
- Works best with 125cc engines
- Suitable for most 90cc–140cc horizontal engines
- Can be used on 70cc engines with slight modification (mounting tab may need elongation)
Fitment Notes:
- May require minor adjustment depending on frame and engine combination
- Not compatible with stock engine guard (clearance issue)
- No spacers, or mounting hardware included
- Rider-quality finish
Great option for builders who want a stock look with modern small-bore engine swaps — clean, simple, and not obnoxiously loud.
We include a free exhaust gasket with every exhaust option.

THE CT70 K1-1982 Black and Chrome Exhaust fit on myYX140 engine perfectly. It is well built and flows well with a good sound. I am well pleased with my purchase and highly recommend this exhaust.
Be aware that this is not a restoration quality item. The size, colors, and fitment are wrong. Will be using for a restomod 125 and should look good
But this exhaust for my 72 CT 70 k1, the factory original exhaust rusted out and broke in half, this bolts directly up and looks sharp, it also a little quieter than the stock muffler, but I'm pleased with the sound, the lower chrome heat guard on the muffler does rub on the chrome spark plug guard but I was able to adjust it away. Also the team at Bart helped me out with a shipping error on my part, got it corrected, great company to do business with!!
