I tried the nitrogen thing a while back. I did not notice a different ride when using nitrogen. I also did not see a single worthwhile side effect from using it. The tires still gained internal PSI after getting hot, and they lost just as much "air" over time. My loss is your gain,, save your money.
bike came new with nitrogen,, but for now i will keep it, and change to air, in the mean time i will also change to a new higher windshield, and maybe that will help calm the front end or buffeting i have conserns about..thanks all...
