A good solid reliable steed. won't knock out 5th gear (which is a problem on the 600), as most, if not all are grey imports, some parts are hard to get but chassis, brakes, wheels, bodywork are pretty much the same as the 600, . the bits that are hard to source are mainly engine related, so get a 400 with a good engine and you'll be fine. there are electric start 400's about (they do retain the kickstart), mainly they are all kickstart, to which there is a knack as on the 600 .... as long as your right leg is serviceable you'll have no problem.
