| Found your answer:
103 cubic inches or 1690cc--the biggest factory-built Harley Big Twin yet.
Milwaukee's maximum 103-inch twin crushes it's little 88-cubic-inch brother with torque right where it hurts: from just off idle all the way to 4500 rpm.
These internal dimensions aren't big news to anyone with a Harley Screamin' Eagle catalog at home. A set of 3.9-inch pistons and cylinders will turn any off-the-rack Twin Cam 88 into a 95-incher. Adding a Screamin' Eagle crankshaft/flywheel to the equation stretches stroke from the stock 88's 4.0 to 4.4 inches and you have your own 103-incher. What you don't have is a warranty or a squeaky-clean 50-state EPA certification. This version delivers both, plus a beefier 1.4-kilowatt starter to coax bigger pistons into action. Given all that, it's fairly steamy for an air-cooled lump with 9.0:1 compression with standard cams, intake and exhaust plumbing.
If torque is the name of the game, the biggest Harley is a player. Strapped to the unflinching Motorcyclist dyno, the factory 103-incher gets with the proverbial program right off idle, churning up 80.3 foot-pounds of torque at 2500 rpm. Hold the throttle open from there and 84.4 foot-pounds of torque arrive at 4250 rpm, followed by 72.8 horsepower at 5500 rpm.
Comparing that with the elementary Twin Cam 88's output of 75.1 foot-pounds of torque and 66.3 horsepower makes Harley's biggest big-incher look pretty good, especially if you concentrate on the bottom of the torque curve.
