i,m afraid the f650 dakar is a waste of time when the going gets real hard its way to heavy especially with hard boxes. in fact i,m very surpised that tony didn,t get seriously hurt. the xchallenge is a lot better bike.
saying that ,the xt was the only bike that always started and never caused any problems.(oil and puntures apart). the bmws were using on average around 20% less fuel than me.
i,ve got a 22 lt. capacity and more than once was filling with 21lts where the bms were filling with 17/18lts. also the f650 and xt were on 17in. rears and using matz karoos. which wore out real quick . the xchallenge on 18in, rear was using mich. deserts and lasted a lot longer.
