I saw this bike at the factory last Feb, and even got to hear the X-wedge run.
Regarding tire size - they said the trend is going back toward taller tires. You can see it in car design, too, with the tall wheels.
X-Wedge - Really sounded sweet. Deep rumble. Test rider said it had tons of torque.
Fake tank - they had removed and crushed that by the time I saw the bike. It had a real tank, unpainted, with the welds all visible. It musta been real, because they ran it.
Big Bike - this is one LOOONG puppy! With the low dropped seat, it would be a hoot to ride.
Tire width - they said they were going to change the rear fender shape to fit the tire closer.
Now, several months later - who knows what condition it is in now.
