Dr. SeussJuice ::something of a different flavor::

Mac Motorcycles just launched and announced itself to the world by way of retro-inspired Cafe Racers.  some VERY sweet bikes; that's the Roarer above - a throwback to "the pre-war glory days".  ah, but what about the motor?  the motor:

Mac Motorcycles are powered by the Buell® single cylinder, air-cooled, 2-valve, push rod, 492cc, 5-speed 'Blast' engine. They're called "thumpers" and with good reason, with one combustion for every 720° of crankshaft rotation when that cylinder fires, it's really an "event".
