Well I had to ask. Looks like a dead end. Hello, The two quotes below where as a direct result of trying to get the law looked at again with the hope of changing it. I have no idea if the Isle of Man has different laws. This question would need to be addressed to which ever authority registers vehicles on the Isle of Man. "We have considered carefully the issues surrounding the use of a motorcycle combination with the sidecar fitted to the right hand side. In view of the implications for general road safety, I do not consider that changes in UK legislation to permit such a configuration can be justified." (Lord Whitty, Parliamentary Under-Secretary of State) "As it has been explained to Uralmoto, GB legislation requires that sidecars must be fitted to the left-hand side of motorcycles and because of the implications for road safety, the Department is not minded to pursue changes in legislation to allow the use of sidecars fitted to the right-hand side of motorcycles. The legislation prohibiting the use of right-hand sidecars was enacted in 1980." (Malcolm Fendick, DETR) Many Thanks, David Angel F2 Motorcycles Ltd
