Both good, but I'd go with the YZ because they are still importing them (Suzuki is still making RM's just not importing them at the moment, same with Kawi) but either would be fine, I would stay away from CR's for moral reasons (Honda's stance on two strokes), KX's, KTM's, Husky's, Gas Gas are all good bikes. if you want easy to find parts stick with YZ, RM, KTM or KX
