Hey all i used to ride a kx125 but thinking of upgrading to a 4 stroke, if i was to upgrade i'm looking at a brand new 2017 crf250r and have heard apparently they're not the most reliable 250f out. so just wondering what everyone's opinion is? i wouldn't be racing the bike more just using it for a mix of everything and would only be riding it maybe 2 times a month at most. P.S i would like for the bike to last as long as possible as i've heard 4 stroke rebuilds are terribly expensive. Thanks.
