Try a bike wrecker. However if the bike is uncommon in your area it may be easier to get a new one. I was able to get a SH one but my local dealer could get a new one for for about $80 australian. That was 2 1/2 years ago <!-- s --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt="" title="Very Happy" /><!-- s -->
