M&m's motorcycle. Home. Untitled. FCB Free Car Brochures. Ace Racer 72. BCM. Ottonero Cafe Racer. Twin Zone. Mac Motorcycles. 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. *Buell is a registered trademark of H-D Michigan, Inc.

Beauty and the Guzzis. Our German neighbors are tifosi with Moto Guzzi, and I understand that, especially when they are cleaned and transformed into real track and road beasts , Axel Budde of Hamburg is a specialist: "I´ve been building Guzzi cafe racers for 14 years, specialized in modifying Le Mans models for street and track.The bikes you see are cleaned Le Mans frames with Le Mans 4 engine housings. The engines develop around 92HP(+) and 104NM torque. All parts and the finish on the bikes are modified or selfmade.
