yeah i am interested in the difference between the wr models. on one hand a little bit more power and a small decrease in weight, plus an Estart(for the 450) would be sweet, but the wr400s and wr426 are very cheap used in comparison. big thing though, since in BC they do insurance by cc class, insuring a 400 would be like 400-500 a year, but a 426 or 450 would be double. 900-1000 a year. question for me is, is that worth it?
