I wouldn't expect XS650 owners to have any difficulty identifying and replacing their ignition keys in the USA but here in Britain things arn't so straightfoward. I thought the following might be useful to other UK and Euro XS owners and is the result of hours of searching and fruitless emails to various UK key Companies . There are numerous similar looking keyblanks where some of the grooves and keyways are different by only 1mm width or placement! This is the key that came with my 1979 Special ll imported from the US . The key blank is made by Errebi but their identificaion Number has unfortunately worn off. 5twins and Weekendrider have helped me identify this key pattern as X117 /YH48 There are numerous other key Companies that produce an identical key blank pattern and each use their own unique key identification Number although all of the following keys are exact copies and equivalent to the Errerbi X117 /YH48 pattern blank. Hope this saves someone hours of searching for a spare key.
