The stock 992cc V-twin already made decent power, so Pegram's engine-builder Dave Weaver just flowed the head and installed a set of Ducati Performance cams and high-compression pistons. That boosted output to 94 horsepower at the rear wheel-slightly stronger than a good-running Harley. "The difference is an XR motor lasts one weekend, while this thing will go thousands of miles," Pegram quips. "It's a lot cheaper, too," adds David Lloyd, who's a big proponent of production-based engines. "It costs $25,000 to build a competitive XR, whereas we've got less than half that in this bike."
