The YB11 is powered by a lightly modified Yamaha YZF1000 ThunderAce donk (go here for dyno charts). This particular Bimota I tested had steel brake lines and an Arrow muffler as the only departures from standard trim. And the 207 Dunlops were not the OE fit. When the owner bought this bike he asked for the Michelins to be changed to the Dunlops...
