At first glance, the Ulysses appears to be built on the existing XB12 platform, and it is--to a point. The engine is the same air-cooled, fuel-injected, 1203cc pushrod V-twin, pumping out an identical 103 horsepower and 84 pound-feet of torque. But while the chassis looks the same, it's not. To adapt it for the Ulysses (and Buell's other new-for-2006 model, the Lightning Long--see page 170), the frame grew a bit longer and wider, and lost the hole through which the engine's air intake used to pass. As a result, fuel capacity is up from 3.8 to 4.4 gallons, and air now enters the airbox via a screened passageway surrounding the fuel filler cap--careful at fill-ups.
