[Grizzly907]

Title says it just wondering what the diffrences are between the first year 660 and the rest. Thanks

I know two major differences between the 02 and the rest.

First was the drive shafts. The 02 drive shaft uses U-joints where the rest changed to CV joints.

Second was the wheel bearings. The 02 used a 2-bearing setup and the rest went to a single wheel bearing.

You ain't going to get no long list like the 700s have in just a few years.
The only thing I saw was an alledgedly changed inner throttle cable and changed axle circlip and changed carbbowl needle and seat. I believe all these changes were BS because they look absolutly the same as the old. Just some sales hype because they were getting grief over these parts.
