Cannondale mountain bikes have had a lot of success with their mono shock, but nothing has been seen on a motorcycle except the NAS concept , Lazareth's derivatives of the NAS, and a similar Guzzi project. Considering an airliner wheel set is essentially a huge mono shock, is there something inherent with the design when applied to a leaning motorcycle that will result in more trouble than its benefits? cost of production and serviceability? Increased stiction? weight of the steering stem and suspension?
