I think Keis is about the only specialist motorcycle kit available from UK suppliers.
I believe it's all 12V ? I think you can also get an external controller for them.
My experiments with cheap chinese stuff is leading me to the conclusion that it's worth saving up for some proper Keis kit. (one day!)
The market place for this kit seems to change all the time, so it'll be interesting to see the developments for next Winter.
