I am the owner of two machines, including the NB8C.
Since the mileage of my 2-inch NB at home has increased since my new car, I bought an ND to protect it.
Even though I bought it after being allowed to test drive it twice at the dealer, it was slow when I tried to ride it calmly.
Even though the basic design has been different for nearly 20 years, the difference between 300cc and XNUMXcc has not been closed, and what I am particularly concerned about is the feeling of tripping when stepping back at high speed cruising and the lack of torque when climbing hills.
If I wanted to improve that feeling, I would start with the intake system, but I thought that with ram air, the response would be better but the torque would be weaker, so I decided on this product, which comes with a reliable K&N replacement filter.
Installation is easy if you don't have anything else, but I dropped the plastic collar into the engine compartment and had to remove the bumper...
The effect after installation was as expected.
It was more than I expected that the sound got thicker from around 3500RPM♪
