Cooling the cylinder head with air is more reliable than water cooling, and prevents overcooling. It also adds the benefits of simpler construction and less maintenance.
While being larger than the muffler used with the .21XM, the VII's muffler is still just as easy to tune, still detachable for easier maintenance, and more responsive than a tuned pipe.
