Have been doing a bit of weekend pootling on the Transalp with D on the back, and have discovered that standard screen, 6' rider with HJC road helmet and 6'3" pillion with an HJC helmet is a bad combination. At 100km every time D moved her head mine went with it. Gives a whole new meaning to the phrase "back seat driver." Fortunately, we don't intend to continue using the Tranny 2 up, so we won't be going for a new screen.
