The problem with motorcycles is there's no manly way to ride along with whoever's steering. Your choices are to straddle the driver from behind or sit in the sidecar.
Personally I'd choose the sidecar, but I'd be ashamed of myself for the entire ride. That sort of self-loathing is likely what drove Robin to an early grave. (You'll always be with us, Chris O'Donnell!)
If I were a braver man I'd grab a skateboard or rollerblades and hold onto the back of the seat.
