The SuperDuke was awesome fun, when it worked.
Depends what you use it for, I used it every day for commuting to work, it didn't take to the Scottish weather at all.
I owned it for a little over two years, reckon it spent close to six months of that in the dealers getting repaired.
Wiring harness and reggy/rec corroded so much they fell off, made the stretch of motorway that it happened on that little more interesting.
Wasn't happy at having to buy two batteries due to this too, apparently they're classes as consumables.
Fuel pump went pop when I was overtaking a van in some twisties, that was fun too.
The oil pressure switch blowing four times and dumping oil everywhere got old very, VERY quickly.
Tyre valves leaking, sprocket bolts chamfering the swingarm
The brakes were awesome, learned to do rolling stoppies with them, was so much fun.
Unfortunately they needed a LOT of cleaning.
A lot.
I had to strip the calipers and re-grease the pistons every month, even that wasn't enough.
The pistons ended up with loads of scarring and chips on them.
Few of the boys crashed due to them seizing whilst riding, KTM's solution was a "technical briefing" letter stating that the brakes needed to be washed and dried after every ride!!
If it's as a weekend toy, go for it.
If you plan to use it more than that, I'd probably pass.
I have been giving serious thought to the new version, but reckon as they don't salt the roads here in Kiwiland then it may, may, just be up for the task.
Some of the nsfw posts about it.
