I normally get two rears for one front so in total I get 18,000 on the front. It is a BIAS tire. It does not cup until right at the end and nothing like a radial. Every front radial I have ever tried to use just cups like a ******* and wears out before the rear.
Pretty sure everyone here will tell you that you can't run a bias on the front and a radial on the back. My FJR just can't seem to tell the difference. Since I am 250 miles from any mountain roads I go for mileage tire combos. When I get to the mountains the bike still goes around corners, can drag a peg if needed, and are pretty comfortable without all the front tire whine.
That front tire will work fine for you and they are around $150.
I run the 170/60-17 ME880 on the rear and get around 8/9000 miles. It is a radial. If you prefer bias on both ends use the ME880 160/70-17. It is made for the Beemer K1200LT. It is a little more narrow but will work fine. Should get 10/11000 out of one of those.
Have fun on your trip.
