Harley-Davidson has just taken the wraps off a massive new crate engine that’s destined for its Touring lineup—that is, it will be available as an add-on. The bikes will not come with this 135 ci V-twin as stock!

Officially, the new powerplant is called the Screamin’ Eagle 135ci Stage IV Performance Crate Engine, and Harley-Davidson says it makes 130 hp at the rear wheel at 5500 rpm, and 143 lb-ft of rear-wheel torque at 3500 rpm. That’s a gain of about 27 percent more torque and 41 percent more horsepower at the rear wheel, says Harley-Davidson—impressive for what’s effectively a bolt-on mod, albeit a very expensive bolt-on mod. Asking price is $7,999.95 US; it does come with a two-year warranty, though!

According to Harley’s press release:
