I purchased my 2014 R3T new in 2015, and the stock Metz's were the absolute worst handling and wearing cruiser tires I've ever experienced. Being pragmatic as hell, I suffered through 'em for 9 thousand miles - literally running the bike gently to help 'em last, and to keep from getting hurt or killed in a curve - before switching over to the Exedra Max w/the V speed rating. I am NOT EXAGGERATING to say that it was a 100% improvement.... the bike just lays over in the corners now w/out having to literally wrestle the thing down through counterstearing. The Metz's unnerved me - particularly on right hand curves (tighter radius?... I couldn't figure it out), which I found weird - in even modest-to-moderate curves... and I wasn't trying to "hot dog" the bike. I literally had to put fair pressure on the handlebars to force it down and through curves.... the bike would wallow through and then want to stand itself up, horribly, in every one. Put on the Exedra Max's, and literally had to then watch out so as not to try to over-confidently play "sport bike" in the curves w/the big machine (effortless handling, now, comparitively) .... THERE WAS THAT MUCH DIFFERENCE, even compared to when the Metz's were new. I will unlikely ever give Metzeler another chance... THEY'RE THAT BAD. In fact, Triumph should be warned that the Metz's, at least on the R3T, ARE DOWNRIGHT DANGEROUS, handling-wise, in my experience.... even when those tires are still virtually new. They will also cause Triumph to lose some sales of new R3T's, as the potential customer will not likely assume that it's the tires that make the Touring handle poorly/alarmingly in some situations on the demo ride.
Assuming I get decent mileage out of 'em (another complaint w/Metz) and don't get any other surprises, I'll be sticking w/the Exedra Max's (with V rating: I suspect they have a stiffer sidewall, for one thing) from here on. Excellent riding/handling tire for the R3T... it literally transformed mine into a real pleasure to ride. (BTW, this wasn't some "newbie" issue with me... I've been riding/cruising/touring since '69, old bikes, old tires, bad tires, almost "no tires" at times (LOL), new bikes, tires, whatever. Even survived a helmet-and-bone crushing full ejection from a Harley in '71 - avoid that one if you can.)
