Phil,
I have some times given a friend of mine a lift on the back of my GTS. She
usually rides with her partner on a XJR-1200 which has a large screen
fitted. She has commented on how comfortable the GTS is.
However she was not prepared for me to "disappear" in front of her when I
decided to over-take a truck,dropped down behind the fairing, and nailed
it.
You can still see the marks of her nails as they came through her gloves
and tried to bury themselves in my ribs!
Other than that she loves the GTS.
Regards,
David
