there's a thread over on the panhead and flathead forum by someone trying to register a servicar in the UK, and asking for the weight. This might be a good time to point out that 3-wheelers in UK must be under 8cwt ( 112lb = 1 cwt, 20 cwt = 1 long ton @ 2240 lb, for our colonial cousins ). 3-wheelers exceeding 8cwt are classified as cars and require a car licence, regardless of the configuration.
They seem to have a weight of 855lb, which seems alot to me, and it is under 8cwt... but it's worth bearing in mind. Could someone who is a member there re-post this?
