Looks like a normal sportsbike size rear tyre so maybe it will have a 17 on the front as well.

If they would just release some more pics I could see me changing my deposit from the SF, in fact had I known about the strada aperta I would have put a deposit on that instead !

if they can soprt the cans out on the SF with a nice aftermarket one - the two on-top cans look awful - I'd rather have one of those...but then I have a GS so dont need another mile muncher ;)
