Hmm, a 250cc two-stroke with relatively heavy bodywork and leading link front suspension (oh, and the CG too far back thanks to the underseat tank like a scooter) against a 4 stroke of up to 650cc, little wasted weight, and tele forks? I think I'd put my money on the Triumphs but more particularly the Beezers on wet roads. I have however always wanted a Squariel.
