Ha. I keep changing my mind too. I'm gonna have to make a decision soon, the stocks are getting pretty squared off, especially after this last trip. It's getting quite noticable and will start flopping over for corners.
I'm pretty much down to the sync vs trail. If the scorp trail came in a 160/60 I would hands down go that way. They are supposedly going to bring out that size next year, we'll see. At least that's what Pirelli customer service told me. I'm figuring I'll probably need new tires almost every year, so I may just do the syncs this time and if the larger rear comes out for the trails then do that next year.
As has been mention previously in this thread, the scorpion trail was designed as an upgrade to the sync, and I imagine Ducati has some pull with Pirelli, maybe not. Maybe they just selected it for the new multistrada as it was introduced. They also are fitted on the new F800GS, and the photos of the new Triumph Tiger 800 have them on it. My understanding is they have a stiffer carcass and is a more durable tire for varied terrain.
The sync is a pretty soft tire, and I guess that's why it works so well on road. There is quite a bit of logic out there amongst riders that these bikes are really road bikes so don't detract from their best quality to be able to ride a dirt road. Any tire will work so pick a good road tire that will do that occasional off pavement trek. Both of these tires excel at this. If Continental would make a front 17 in the Trail Attack that is also purported to be an excellent dual sport tire for big roadies.
BTW, the scorp trail also comes in a 'G' spec and from what I've been able to tell it's a higher speed rating for the F800 and multistrada. Would also be applicable to the Versys if you're an aggressive rider. They run about $10 more on the rear tire.
I consider myself a pretty aggressive rider on road and definitely don't want to sacrifice the superior capabilities the Versys offers. They make a wonderful canyon carver as well as an over the road bike. The syncs are also quite popular with the Tiger owners. They have been said to work just as good as a distanzia off pavement, and quite a bit better on dry pavement.
