In short, you get a bunch of parts for the top end of the engine—new cylinder heads, and forged pistons—as well as a full Akrapovic race exhaust system and a flashed ECU. The end result is 215 claimed horsepower from the 65-degree V-4 and what I can only assume is a noise from the end of the pipe that would make Satan’s pit bull wee on the carpet. The other way to “add” horsepower, just like your trainer keeps saying, is to lose weight. This Factory Works kit also includes a lithium battery, machined-aluminum upper triple clamp, a different fuel cell, all-new bodywork, and a bunch of carbon bits that shed around 22 pounds off the stock RSV4. To be fair, a stock RSV4 isn’t crazy light, so losing 10 kilos was on the to-do list anyway. Mirror block-off plates help complete the race look and shave a little weight by kicking off the stalks, too.
