Seat probably the best bet.
Please dont do what one SA bloke did where I go.
He Rides a Honda Pan and is an advanced instructer-Had two pairs of extra thick soles glued on to his boots! No really-I did not believe it until I saw it with my own eyes.
Rides up looking like a fluro copper and gets of looking like Ziggy Stardust!
The brunt of many a P***s take.
