Got to add my two penny worth...
I have put 26k on my main DL1000 and in those miles I have always had Trailwings on except for one set of Battlewings.
I got 10k out of my first rear Trailwing which was amazing, but I never managed to replicate it. I gave Battlewings a try about 2 sets of tyres in and to say I wasn't impressed doesn't cover it. They were rubbish in the wet, they just let go with no warning. They wore out really quick, being a softer rubber and they cost more. So it was back to Trailwings.
I recently went on a tour of John O'Groats on my newer DL1000 which had 4k on and the original trailwings. The rough roads up there sorted the tyres out and I needed a new rear tyre when I got back.
I went into National Tyres and was told they didn't do Trailwings anymore- disaster. But luckily they found one V rated rear tyre left so I had that. Don't know what I'm going to fit when Trailwings disappear, probably Avons.
My other DL1000 has road tyres on - Bridgestone 020s which I like but you can't get those anymore either.....
Don't know if I ought to say this on a Vstrom site but I have also fitted Trailwings to my Varadero XL1000 which I ride through winter, that's how confident I am in TWs!
It looks like I'll be the only one mourning the end of Trailwings. But in my opinion they were a great tyre. I've been round tight corners two up, everything scraping and out cornered sports bikes. They gave great feedback in the wet, you knew exactly when the back end was going to slide and the front never did. They gave much better mileage than Battlewings and were cheaper.
Suzuki knew what they were doing when they fitted Trailwings as original equipment to the DL1000.
