this bike is interesting to me. i've read a review in the May issue of "twowheels" and the reviewer had nothing but praise for the bike. was wondering if anybody has one or has test ridden one could you write your thoughts on this bike down? thanks. also i'm not sure if its learner legal cause i looked up the list of LAMS in NSW and it has: LC4 SERIES 300 LC4 SERIES 400 LC4 SERIES 500 LC4 SERIES 540 LC4 SERIES 550 LC4 SERIES 600 LC4 SERIES 625 LC4 SERIES 650 but no LC4 640......since the 650 is there i can's see why the 640 isn't.... also lastly there's been alot of threads on 2 and 4 strokers.....i just want to know if there's any difference to longevity/performance/handling/etc of a single cylinder such as the one in this bike?
