While the displacement wars rage on in the heavy cruiser market, with the Big Four trying to outdo each other, and now Triumph is promoting Piston envy, it's good to remember that there is still a lot going on in the middleweight category, which now is really considered entry level. Honda has placed all their eggs in the new Shadow Aero 750's basket. I think they made a good choice.
The biggest news with the Aero is that Honda dropped the chain drive from the old 750's in favor of a quiet maintenance-free shaft drive. Now this 750 competes on a level playing field with the Suzuki Intruder and Volusia 800's, the Kawasaki Vulcan 750, and the Yamaha Vstar 650, which now may feel the pressure to bump up their displacement to the 750 ranges soon.
