So what does a scorpa 4t sound like then? 
 
Not like a motocrosser!  Curious to hear the new ones, with the single outlet exhaust. Hopefully, it doesn't make it louder.  The dual outlet exhuast did a good job of minimizing that 4-stroke bark, that many find offensive.  At a trial, we used to laugh at how much the Scorpa souded like an old Honda trail bike, coming through the woods, while the Montesa didn't sound like a Honda at all.  I still have my 1970 Honda SL-100, and was always amazed at how similar my Scorpa SY250F sounded. Same mechanical cam-chain sound, and all.  I have a Beta REV-4T on the way now, so I am anxious to see what it is like.  All the input I have received reports it to be the most quiet, of them all, so far. 
 
You haven't heard Freixas' then!
