The engineers and technicians at RevTech® went back to the drawing board to create our next generation 100" engine. We studied the latest technology, combined that with expertise gained on the first RevTech® 100 project, and got down to the task at hand. The goal was simple; create the best all-around engine for the American V-Twin market! Fortunately, the RevTech® design staff did not have to start from scratch. We began with a solid foundation, the fire breathing RevTech® 110 power plant, and refined it further to produce a motor for most everyone. By shortening the stroke to 4", excellent balance with less vibration was achieved. A positive side-effect of the shorter stroke was reduced piston speed which increases reliability due to lowered stresses. The 4" pistons pushed on these 4" strokes are a special story in themselves. RevTech® worked with Wossner to design unique moly-coated forged pistons specifically for our engines. If you re not familiar with Wossner, here s a bit of background, they make pistons for a little company called Porsche, among others! Next we redesigned the heads. The bigger bore of the new 100 allowed the use of larger valves, so the ports were also redesigned for better flow. Smaller combustion chambers provide greater squish area for better turbulence and efficiency. In addition, roller rockers are employed for better valve train reliability. Many of the fine features of the RevTech® 110 were retained due to their proven success. Pressed-together flywheels and our industry-first monoblock crankcases are still used for excellent reliability. Blind case bolts, machined fin edges, and john reed design"! rocker boxes follow the RevTech® tradition of making it work good, and look good. And loads of horsepower and torque for all types of riding come standard. So did we reach our goal of the best all-around engine on the market? We think we did and believe you ll agree. Remember, there are millions of American V-Twin motorcycles on the road today; why not make yours perform like one-in-a-million?
