The spread is 3.64. It is for a sheet metal, non WCD chassis. I considered putting the motors over the wheels, but I decided that the CG benefits of lowering 17 pounds around 4 inches would be more beneficial. My weight estimate only says 10.999 lbs, but I was comparing it to the 12.94 value from http://www.wcproducts.net/wcp-shifter-3cim/ (Standard, non-WCD, with 3 14t motor pinions, motors and 1 pneumatic cylinder). I think mine has one or two fewer gears and is thinner, but .2 lbs can probably account for that. I wonder how they got 12.94 lbs?

Makes sense. I normally value space savings vs CG. I've been a bit envious of 125's setup this past year.

The "builder" on the site doesn't work so hot, its mainly an approximation for shipping. We'll be fixing that value in the coming months with a site update.
