Hi Simon, that seat looks familiar! The k3 grabrail is very hard to find as it is only fitted to the k3, and the US type is different. here is a pic of the k3 that i had which has the correct rear light bracket, never did get the correct grab rail.
To change that rail, you will also need a different rear mudguard as well, as a tail light bracket.
