I 've had 4 airheads and spent a LOT of miles on a friend's R100GS/Dakar(in Europe). Then I rode my first KLR in '89. Sold the last Airhead and never looked back. Why ? Because the KLR just handled the pavement so much better. The Germans didn't call them "Gummy Cows" for nothing.
Coming up on 100K miles on 3 KLR's since.
Just my $.02.
