I'm 5' 8", my Tenere is not a problem...
The reason why bike heights may differ could be down to the shock absorber. At one time I had two 3AJs, it was quite obvious that one was higher than the other. During rebuild/s I pulled both rear shock abserbers and compared them - one was slightly longer than the other.
A bit more research revealed that a shock from a TT600 will fit into an XT600, but the TT600 shock is a little longer - resulting in higher ride height. My shock is from a TT600 - and I appreciate the extra height/travel when offroad and loaded up.
If you're going to replace your shock anyway, most decent shocks have adjustable links (maxton, wp, ohlins) - so this may solve the problem. Also you could just drop the forks through the yokes a little to balance things up - but check clearance front wheel against exhaust pipes...
