CIM --> 12:1 --> 6" wheel gives a speed of ~11 fps (theoretical) with direct drive. My guess is they wanted 6" wheels for the speed, yet also wanted the lower weight of 4" wheels (since there are 4 of them, that weight savings adds up). Since the outer wheels are driven via sprockets, this seems like a very logical setup for the drive train.
No troubles turning with the 1.5" wide wheels on the corners?
