Straight from Yoshimura Japan!
This is a trick little exhaust system for the NSF100s. It features Yoshimura Japan's Famous Cyclone Muffler with a straight baffle and Carbon Fiber sleeve. The headers and tail-pipe are CNC-bent from high-grade Titanium for maximum weight savings. On a small bike, every pound makes a difference! This Cyclone system adds a little grunt to the bottom end, but really shines up top, getting the most from your stock or highly modified Yoshimura Japan 125cc Engine Kits.
NOTE: Requires modification to under fairing.
All necessary hardware is included, along with detailed installation instructions! Instructions also include templates for necessary modifications to the under fairing.
dB Level: 99dB @ 4000RPM
