What would be a reasonable option?
I don't want a death trap but I also don't want to buy 2 sets of tires a year.
Then you should not have purchased an open-class superbike.
There is no tire you can get that will deliver the mileage you hope for and enough traction to match the bike for the kind of money you want to spend.
Some guys run the Michelin Pilot Power 3, or the Dunlop RoadSmart II and if you are a conservative rider you might be OK with that type of setup. Those tires give adequate traction midcorner but then almost any tire will do that.
Where you run into problems is the extremely high levels of acceleration and deceleration this bike can generate.
I ride very smoothly most of the time and know my bike and the roads I ride pretty well. Even so I had the KTRC kick in the other day, on Low Power with the KTRC set to 1. I was cranked over quite far and dialing it up and the cylinders cut for about 0.2 of a second. That's the most aggressive level of TC, when the cylinders cut out.
Obviously there was something on the road I didn't see, perhaps a small pebble or a tiny spot of diesel, but without the KTRC things might have been more interesting.
This is with premium rubber, pretty fresh. You put something else on there you are asking for trouble.
You just have to budget the money for tires with a bike like this.
