Here is a quote from another forum regarding the throttle issue and by an owner of both an NC and a VFR1200X.
"Use the NC700x and the VFR1200x the same.........75% paved and 25% gravel and fire/forest road.
Sold a St1300 when I purchased the VFR.
Right now the NC is sitting a lot..................as the VFR so smooth, great power, comfort. My only complaint ( annoying) on the VFR the throttle is snatchy ( very sensitive at speeds below 40 mph noticeable on rough roads). I have a throttle tamer which made it better."
