Fairwell to Air-cooled engines?

[Henrik_imp]

I too think the noise argument is not really one. Ultimately it is possible to make a water cooled engine quieter than an air cooled one, but there are so many other things that impact this aspect. I remember my Ducati ST2, which was a water cooled 944cc engine, as being mechanically very noisy. The desmo valve system and especially the dry clutch made quite a racket, and a friend used to refer to it as the stone crusher. At the end of the day, it will always be the exhaust pipes, or lack thereof, that make the most noise on a bike.

The CB11? By far the most silent bike I have ever owned...
