I do not ride with pilion but a friend of mine bought this and I think it is the best solution for the pilion.
Yip - At the Kawasaki day earlier this year Leon Haslam had one on his, he was taking pillion's round with....which i thought was pretty nifty..
till ya crash... Imagine the damage should you come to an abrupt stop and slide up the tank at speed. Heard horror stories from a mates old man about the racks they use to have atop of the tank on old brit bikes.. No thanks!
I'm also just gonna take it really really easy when she's on... she's gonna have to get her own bike to feel any acceleration l.
I find the lady pillion can reach around and hold onto my willy (not in cold weather and only one hand)
Learning from past close calls, I have bought a bike-it pillion grip handle belt thingy and a triboseat cover. It's rained on-stop since then anyway so haven't been out with those to try them but they look like they will do the job.
