Maybe, but I have almost 40 years on bikes. If you were local to me, I'd let you take a ride with me and say that
After 3 hours in the seat, I had a mild sore throat from the fumes. The better half refuses to ride it in now until I resolve it.
haha which is why I said "Most" is instead of "All", fumes are bad if you have a tall windshield and or a top so to avoid fumes that type of person should get a vented windshield like the madstad but then they complaint about the wind noise and turbulence.
Also for the record the first thing I do to every bike I have owned is change the exhaust for an aftermarket without cat so maybe my tolerance for fumes is high.
