From their web site:
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".
Valve adjustment is automatic, using hydraulic lifters. The transmission is down low giving a low centre-of-gravity that helps great handling. The fuel is enriched en route to the pot. Mac bikes exploit the power-to-weight ratio principle with this great little motor and a very light rolling-chassis.
Stock motors produce 34 HP at 6500 RPM but a bolt-on big-bore kit (515 cc), Andrews Cams, a Mikuni HSR 42 carb', Screamin' Eagle ignition and a Supertrapp exhaust will produce around 50 HP at 7200 RPM. A Blast running an NRHS 515 kit set a record at Bonneville in the 650 class, whilst much of the tuning potential of the motor has been exploited by the short and flat track racers in the States.

thats actually a cool looking bike.
I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago.

Does look like a tame version of a He11cat. The Mac bikes are all the same bike with a few minor changes.

Great name for a motorcyclr company. Sexy too!
