since my last post I did buy a bike a 1997 yz 125 I have been riding it lol I have been ridding it a lot ! Thanks to al the people who have posted on here with ideas and modifications they have done on their bikes or quads I do plan on putting a electric push button shifter and a left hand handle bar mounted rear brake, any suggestions besides a clake system , I am thinking of a snowmachine rear brake they are on the lh side on them

Have you looked at the national association of disabled bikers (UK) http://www.nabd.org.uk/ ?

I found the group so helpful and amazingly friendly when I went there asking questions (wanted to get myself a trike... yeah still waiting on that one!)
