I thougt smaller engine smaller quad not on AC I think it looked bigger. Sales guy sad same frame but it looked bigger.

 

The 375 and up are the same size. Width, Length, and Height.
The 300 and 250 the length is a hair shorter and about 4" lower.

I don't know if she will be willing to shift or not. But if she would, the 300 is easier to handle than the 375. My wife felt overwelmed by the size of the 375, that is why she opted for the 300.

 

The sale guy said AC use the same frame just smaller tires. I just hope I can find a used quad in 5 weeks.
