MV is going to go bankrupt. Stuff like this wont cut it. The markets too tight and MV management is too shady. They will be out of business in 5 years or less. I bet my bottom dollar on it.
The earplugs aren’t so much for the exhaust. It’s because of the wind noise especially with carbon fiber race helmets. If you’re riding at highway speeds you should always wear earplugs or you’ll have irreversible hearing damage by 30 years old.
I own a 2016 MV Agusta F4 (Pearl White) Bought it 4 years ago with 1,600 miles, i now have over 48k miles…not one issue with the bike. They are very reliable, just have to take care of them.
