Omigod!! it's total bike porn - these things are absolute poetry in motion, even when stood still. As a guy who grew up on Elsie's, mostly (or moistly!) on 250/350LC's I can well understand your passion.
Alloy frames and quasi-V4 two stroke mayhem. God I wish I had the money!! Just been down the Thundersprint and saw a mint, standard RD350LC - absolute class. I bought my first 250LC for £300 in 1987, it was a dog but I loved that bike and wish I had it still, as well as the 350 and the absolute mint import RZ250LC with 16000kms and original fuses). Then it was 350's, YPVS', TZR (parallel and reverse cylinder). I've been Yamaha ever since - hence the SZR (via 2 x FZR's which were as close as 4 strokes got to the nutter culture of the Elsie)
