I have been riding motocross more years than I care to admit, and as the race bike frames became stronger/stiffer the suspension settings became more critical. It is the same for the big heavy Harley. The frame flex and overall slop had one advantage...the bumps were absorbed by the shocks and forks and the frame. Now you have only the forks and shocks to soak up those bumps. The good news is you can have both handling and ride but you will need to be much more attentive to air pressure in your shocks.
If your shocks are low on air your bike will sag in the rear and then in a small way your forks will be more raked out (think chopper). Then your forks don't work properly either, they are too raked and they are "unloaded". In this situation both handling and ride will stink.
ABOVE IS THE SUGGESTION I GOT FROM GUPPYTRASH BEAR THIS IN MIND & WORK WITH IT I SETTLED FOR 35LBS
