Hmmm interesting? Now with us is this BMW K100 based trike (properly registered as a trike on the V5). Originally sold by its owner (for a lot more than its current asking price) it soon after developed an electrical fault and cut out so he refunded the money and took it back. He thought for some reason, being a panel beater sprayer, he would be able to find the problem wrong! Now replaced by a very pretty Goldwing trike it has sat in his garage ever since.
A proper conversion complete with hand break, it was all MOT’d and on the road. Now offered as a project and non running.
