pros:
very protective helmets - know of a few (too many) that crashed wearing a suomy spec1r and the helmet did it's job and beyond....one sled down the road for a good distance and pace enough to wear a hole through the helmet and even hit a mailbox and still came out fine....
awesome paintjobs on them - a lot better looking graphics than most others including the the pricier arai/shoei...
OEM visor resist fogging..
great venting for hot days...
padding seems to mold with body temp...
cons:
loud as mentioned...
sucks on very cold days due to the aggressive vents...
aftermarket visors fog up the worst than any other helmets...
paddings stay stiff on cold days...
