You are 185cm high (I did conversion) and thus high enough for the standard T�n�r�. I am 10cm shorter than you and able to ride a -3cm lowered Ten. It still is very high for me but definitely manageable, but to make it friendlier I will customize the seat to gain another 1cm or so.

You can get the easy ride kit from Yamaha, which has longer rods (sorry, don't know how to call those) that lower the bike by 1,5cm AND a lowered seat which lowers your position of another 1,5cm, for a total of -3cm as I mentioned earlier. Don't forget to pull out a bit front forks to balance the lowered tail.

Not easy to keep that heavy bike up off-road if you are unsure on your legs, that's why I'm lowering it a bit more.
