How much power are we talkin'?

One of the selling points of the 2016 Softail Slim S is its engine. For the first time ever, Harley-Davidson threw its Screamin’ Eagle Twin Cam 110 into something other than a CVO model. The Screamin’ Eagle Twin Cam 110 package of the 2016 Softail Slim S includes a Screamin’ Eagle Stage 1 high-flow intake and jet-black over/under dual shotgun mufflers.

After riding it for over a 1,000 miles already, we know first-hand how the Softail Slim S pulls like a horse. In typical Harley fashion, it provides a bounty of torque almost off idle. It has no problem picking back up from low rpm, too. We wish it had a little more over-rev because once it hits redline it shuts down. Roll-on is on point, though, as we’ve left plenty of big rigs in our wake with a quick twist of its throttle on our daily commute up I-5. Throttle response is definitely a strong point as it reacts to input in a snap.

That said, we were eager to see exactly what the Screamin’ Eagle Twin Cam 110 puts out. So we took it to a reliable third party, Hansen’s Motorcycles in Medford, Oregon, and threw it on their Dynojet. For old time’s sake, we got our former off-road editor and dyno vet JC Hilderbrand to do the honors of rolling out the throttle. Rear wheel spinning, the pipes rumble bouncing off the walls, spent gas filling our lungs – just like old times!

After seven runs, the 2016 Softail Slim S put up peak torque numbers of 96.79 lb-ft at 3,600 rpm and 81.74 hp at 5,000 rpm. At 2,300 rpm it’s already pumping out more than 90 lb-ft of torque and stays there until 4,700 rpm. On the horsepower side, the Twin Cam 110 churns out 80 hp from 4,700 rpm to 5,400 rpm. As mentioned, around 5,800 rpm, everything flat lines.

We’ve included results of the top run below for your inspection. We’ll have a full review of the 2016 Softail Slim S to go along with these dyno results posted up soon.
