I am 6'2 and I got stock 07 S40.
No problems with size and also nothing
to compare to as I only rode scooters before.
I actually also had passengers and bike
was great even in the rain...
I am not sure how size comes to play with
the bigger bikes. On all of them most
people need to be able to reach all controls...
Either way, most I did was 400km in a day
and only thing I wanted was better padding
I have sportster seat on order from member here
so I'll see how that goes...
Cheers!
