RevTech 100" 4x4 Engines - 4” Bore x 4” Stroke Crankcases
The engineers and technicians at RevTech went back to the drawing board to • Cast from 356-T6 aluminum with wall thickness optimized for maximum

engine for the American V-Twin market! • Smooth crankcase deck to cylinder base profile for cleaner appearance
• 7/16" cylinder studs proven in drag racing applications
Fortunately, the RevTech design staff did not have to start from scratch. Flywheels
• Flywheels are Forged from 4140 Steel
We began with a solid foundation, the fire breathing RevTech 110 power • Connecting rods are forged from 4340 Chromemoly Steel - the strongest
plant, and refined it further to produce a motor for most everyone. By material available for this application
shortening the stroke to 4", excellent balance with less vibration was achieved. • Larger, straight 1-1/2" Diameter, Pressed-in Crankpin from 8620 Gear Material
A positive side-effect of the shorter stroke was reduced piston speed which
increases reliability due to lowered stresses. Oiling System
• The most advanced oil scavenging system produced yet for air-cooled
V-twin applications resulting in better reliability and increased horsepower
The 4" pistons pushed on these 4" strokes are a special story in themselves. • 3:1 ratio oil pump drive gears and high volume oil pump
RevTech worked with KB to design unique moly-coated forged pistons enable significantly increased lubrication and cooling
specifically for our engines.
• Piston cooling oil jets for better heat dissipation
Next we redesigned the heads. The bigger bore of the new 100 allowed the Cylinders
use of larger valves, so the ports were also redesigned for better flow. • 4"-bore for optimum power and reliability
