How much horsepower does a stock Twin Cam 96 have?
Simulated rear‑wheel horsepower and torque — measured after the primary drive, clutch and transmission, the same way a chassis dyno reads a bike. These are not flywheel numbers, and they are not directly comparable to a manufacturer’s crank rating. Rev ceiling for this combination: 5500 rpm, limited by engine.
The 96 arrived in 2007 with fuel injection, the -06 head casting and the longer 4-3/8" stroke. It is the most common Twin Cam on the road.
Read at the rear wheel. The stroke is doing the work here — torque arrives early and the curve is flat through the range you actually ride in, which is exactly what the engine was designed for and exactly why the peak number underwhelms people who only read peaks.
The honest summary of a stock 96: it is a torque engine with a cam that quits early. Everything worth doing to it addresses the second half of that sentence.
