I changed to Avon Storm whick give complete high speed stability and grip when going for it but less, marginal, feedback than the stock Dunlops. I have had success with Continental Road Attack and Bridgestone 020's on other Bike's.
The Dunlops are unstable over 90 mph in my experiance.
Pirelli Scorpion Sync, nothing else! A friend of mine with a Multistrada was going like the wind, had his knee down to the ground and never faced any sliding. We checked also Pirelli Diablo and Bridgestone BT10 but there weren't so good. Go ahead with the Pirelli Sync and you will see.
