On my recent trip to Reno I noticed a lot of people traveling on various bikes with both soft and hard luggage. I followed a biker with a loaded bike (V-Strom) and noticed at speeds over 90+ the bike started to shake and become unstable! He was still cranking it on! Riders need to realize that the bags both soft and hard have a manufactures top allowed speed! Normally between 120 to 140kms before the bike becomes unstable. Riders on smaller bikes, IE the 650s, need to be aware of this. Riders need to take in consideration their weight, Weight of load and way the bike is packed. Everything contributes to the stability of the bike. In Europe most bikes have spring loaded mounting systems to take up the shock of high speeds. My 06, 1000 will run about 90 before it starts shaking. So dont go so fast! And when the bike starts shaking and dancing, GET OFF THE GAS! The Bike is telling you something! Bob.
