Ducati need frequent (3k to 5k miles) adj. They are nice exotic V-Twin bike... period. My Suzuki SV1000S V-Twin goes a 20k miles between valve adj. produce way more power and torque for the same amounth of CC. The RC51 is also an awsome V-Twin, sadly, it's run way to hot for the legs. They all use T-Chain, but i fitted mine with an external T-Belt :-), a Subi one... Ben
