Saw the lineup for the '05 models. Some worthwhile changes.

New AC built engine- 650 cc single cylinder- (designated H1)- to go with regular Kawasaki 650 V-Twin (V-2).
Plastic has been redesigned and is less boxy looking on 500 and 650. Fenders are wider to keep the mud down.
MRP system is improved so you don't have to remove any part of the rack to install accessories.
Foot Brake actually works!!!!!
Bigger and more comfortable seat.
Digital gauges on 400 and TRV.
Locker on 400.
LE has slick front and rear bumpers.
Great looking Aluminum wheels.
Available sway bar.

There are some changes to the sport ATVs too but I don't know anything about them to know of changes.

One drawback I did notice is the dry weights went up a bunch. Several units now over 700 lbs.

 

Are they at the dealers yet? If not, when will they be there?

 

My dealer already had some of the smaller units. The TRVs were expected this week and 500 and 650 in the next week or two.

 

got to see a 500 over the weekend. They look really sharp!
