pretty sure the V-rod is still the only liquid cooled HD.
One thing about cruisers is you cannot beat the looks of an air cooled engine, once you put a radiator on a bike without fairings it just ruins it for me. my dad has a yamaha raider S air cooled and it is a sweet looking bike, yamaha makes another bike slightly smaller motor and liquid cooled and it looks like a tard, driveability is improved around town and in traffic though but man do the air cooled motors look slick!
that victory really pulls of the radiator well since it has fairings on it all over, slick looking bike but my dream bike is still a HD fat boy
