this whole thread has being pointless,no offence jacks_bikes but many of these questions could of been answered if you used the "search" function on here.both dhz 140 and 160's are good bikes,as said by carlts he has strengthened his shock mount which was a common fault on the crf70 style dhz's.i believe dhz-xr8racing has bent a few of this particular frame but ken from dhz has replaced em all under warranty.correct me if im wrong.if i was you i'd go into the dhz store and have a sit on both bikes and a test ride if possible,in the end its all up to you we cant decide what suits you cos in the end your only gunna get 50/50 answers on whats better.good luck with the buy though mate which ever way you decide to go you wont be disapointed.
