Lock also had a slipper clutch and a (claimed) 2-pound-lighter flywheel fitted; each has less-clear-cut advantages than the power-up kit. For example, the lighter flywheel makes the normally somewhat lazy-feeling (compared to a current Japanese inline-four middleweight) V-twin positively whippy. It's the sort of modification that completely alters the Multistrada's behavior, making the whole bike feel livelier, more eager. But as staffer Carrithers points out, there's a fine line between responsiveness and being jumpy or jerky, and for some riders the lighter-flywheel Multistrada can be overly sensitive to throttle inputs. Likewise, the slipper clutch draws mixed reviews. It occasionally exhibits some Ducati performance clutches' usual bad behavior, with a noisy, grabby and inconsistent engagement point, especially from cold. Plus, staffers and Lock all agree that while a slipper clutch might be pure gold at the racetrack, it is difficult to hammer the thing hard enough on the street to make it truly worthwhile.
