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. 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.
The Return of the Cafe Racers BCM Vintage Racers BellaDonna Trackers MeanMachines « Custom motorcycles MeanMachines Cafe-racer.info Red Baron Triumph Bonneville Cafe Racer Earlier this year I ran a story on the "Big Chill", an '08 Triumph Bonneville Cafe Racer built by custom workshop Mean Machines. This latest Hinckley Bonneville from the Sydney based outfit which is aptly named the "Red Baron", is essentially the same build spec as the Big Chill with one major difference, it has much bigger balls. Mean Machines were obviously happy with how the Big Chill Bonnie turned out. The Red Baron has identical handling tweaks, the same lighting set up, the same fibreglass bodywork and the same rear foot pegs. While replicating a previous build might sound like a cop out the Red Baron is still an impressively thorough customisation of the donor bike. All the planning and design work that went in to the Big Chill has resulted in a "Bonneville formula" that produces a great handling and good looking Cafe Racer, so they did the one thing that anyone would do, they increased the bikes power. That's a little over 120cc's of extra engine capacity. Build spec:
Fast and tracksWelcome to the Frontpage it roCkS! CB750 Gravedigger Osvaldo Coutinho and Alexandre Santos are the guys behind it roCkS!bikes, based in Oporto in Portugal. They are both engineers and self-confessed motorcycle addicts. This CB750 is a little different from the usual CeeBee customs out there as it’s based on a 1992 bike, rather than the usual 1970s donors that feature on most of our pages. This bike was built as a showcase for it roCkS! The donor for “Gravedigger” was a lucky find, sitting in a local dealer in excellent condition. The bike was completely disassembled and everything heavy was dumped or replaced to minimise weight. The engine was in very good shape, but it was rebuilt anyway, and painted in matte black. The tank, seat and rear section of the bike are one single metal piece that can be lifted for access to the gel battery, fuse box and other electricals. The digital dashboard is a Motogadget Motoscop Pro, which features all kinds of switable information like rev counter, gear, 0-100km/h acceleration, g-meter, etc.
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."Customers interested in special Guzzis, please contact me via my Website or call +49 40 81901891 / +49 160 6370483 (mobile).
