All 3 wheelers silly? I don't think so.A friend of ours had a 3 wheel offroad - god damn stupidly dangerous things aye, so easy to roll.
Tbh, anything with 3 wheels is a little silly.
(edit) dunno why that wont embed properly, its the TopGear episode with the rollypolly Reliant Robin.
I saw a cracking race at Snetterton about 20 years ago, 3 Morgans, and half a dozen Triumph Triples. The Morgans came 1st, 2nd, and 3rd.
