Got a Distanzia rear on my sm610 about a week ago.
I opted for the 150/70/17 as opposed to the 150/60/17 size that would have matched my OEM size.
Given how quickly my 610 eats rear tires, I figured I'd be doing myself a favor by grabbing the dual sport compound, and it's my understanding that they don't make a 150/60/17 that isn't the softer SM compound.
I knew it'd be a little taller, but please note: It's really distinct.
If you're thinking about getting the 70 profile, please know that there will be a LOT more rubber filling out your rear wheel well than before, and anticipate the bike being "geared" taller, as the diameter of that rear wheel makes it behave as if you've added a tooth to the countersprocket or dropped a few in the rear. No more easy power up wheelies, even in first
and as expected, there's a notable change in turn-in.
That being said, the tire is plenty sticky so far. I'm running it at 24 cold, and it's behaving quite well. Not enough play time in the dirt yet to make me feel happy about dropping $230 in total just for the rear, but hopefully that'll be rendered once I get to Adams or do some trail riding or camping.
If I could do it again (and I wish I could), I would've gotten the stock size, and dealt with the shorter life span.
My two cents.
