Any kind of lift is murder on the trail's short suspension. Just no way to have a decent ride and great clearance with such short a-arms.
I'd have to think it should be possible to get as good a ride as an ATV, since the A-arms on those must be of similar length.
I do think that the CF Moto design in suspension has unusually short travel however even compared with a quad, as I remember measuring the stock shock rod travel on rear at 1.5". This would require CF Moto to supply a damned strong spring just to keep it from bottoming out.
I too found that even jumping on the rear receiver at 250 lbs, the quad hardly noticed nor responded. Was like jumping on a railroad track, moved about the same amount.
