Rear grab rail
 

Took the misses out for the 1st time yesterday on the 660z with Yamaha side boxes and after we worked out how to get on! She said she would prefer a rear grab rail rather than the side ones, is there one for them?

Not seen one. Get an oxford products Pillion Pal - its a set of handles you strap round your waist so the pillion can hang onto them. Or fit a topbox :)
