170/60 R17 Tires

Mounted on TDM 900.
Heats up quickly.
Very good grip.
Poor durability for a touring tire.

I've used the dunlop mutants on my ducati multistrada v2s and i'm not too happy about them. My only reference is the OEM pirelli scorpion trail 2s and the mutants are worse on dry, they slip more than the scorpions; not much, they just slip enough to make me loose confidence.
On wet i'd say they are equal, maybe a bit better than the pirelli's, but i ride very carefully on the wet anyway.
Off road is their strong area. you can feel them grip much better than the oem pirelli's, but since i very rarely go off road, i'll stick to the pirelli's for my next tire change.
Finally, they are not as durable; they squared off after only 8000km. now i'm at 10000km on them and looking to take them off. The pirelli's started squaring at 10000 and i changed them at 13000. The tread is still adequate though, it's the squaring that makes me wanna take them off, as they've become more "edgy" on lean.

from an st1300 Pan European using the GT version of the BT31 tire front and rear

dry grip - great if smoothish, found slightly rough (UK B roads) had a little bit of a skip feel on even shallow bends)
wet grip - good compared to past but have had better from sports tires.
road feed back - sometimes a little too much. feels like a slip when it isn't sometimes. but great feed back on what you want too
handling - I'm no racer but can have a good spirited ride with the sports bikes and keep up fine. Normal road surface and good weather a large bike handles well
comfort - great, but could also be the bike to be honest
buy again - YES! about to buy another set now! 11500 miles to a rear (although destroyed it on the last 100 mile) and the front is still legal! (just). I would never ride a tire beyond the legal limits but the rear went from 2m reminders to a middle section missing in 100 mile. I cant complain at getting over 11000 miles before it was a problem. change before the limits and you will still have your monies worth! and it was still gripping like a good tire. I also don't potter about so it took a beating.

I've just put a pair of these (120 x 70 x 17 front, 170 x 60 x 17 rear) on a 1996 Kawasaki GPZ1100 to replace Metzler Roadtec Z6. The bike is transformed, at 142kg dry it's no lightweight, it's always felt on the heavy side particularly at low speed, I was running the Z6 front tire over recommended pressure to lighten the steering, at recommended pressure the steering was really heavy with very noticeable counter steering effort required to get it to lean, not nice. With these fitted and at recommended pressure the steering is light, the ride is much improved, much smoother, it tips into corners effortlessly without thinking about counter steering. Low speed handling is way lighter, and the front is noticeably quieter. It's like a different bike, in a good way. Dry grip is excellent, I've not driven with them in the wet so can't comment, and not had them long enough to comment on wear. Would I buy them again? Unless they wear quickly or some other anomaly appears with use, yes definitely.

Very confidence inspiring in wet and dry conditions. Rears don’t last too long (approx 4000 miles, but this is on a powerful torquey bike) and the front tire sometimes makes a weird howling noise when cornering. Great tires though; I’m on the second front and third rear now on this bike. Recommended.

I've had Metzeler Tourance tires on all of my 1200GS bikes. They've held their own on the track, A-roads and B-roads in all weathers and I have never lost faith in their ability to give the desired grip when needed. I get between 6000-9000 miles out of a set.

R1200 GS. Great on the road a bit noisy but I like to hear how the tire is working. On a trip to Scotland got a puncture from the rough pavement surface on Skye and a couple of days later a slow puncture from some stones on the road that got embedded in the tire. Not claiming to be a trail tire of any kind so fair enough but any of the 90 road/ 10 trail tires were significantly more substantial

I used the EXEDRA MAX (Radial), which is better than the bias ply version, on a Honda ST1300 while riding around Australia. Two up and towing a trailer full of camping gear at 100+km/h, the rear tire lasted the 8,000km from Townsville to Perth, via Broome.

None of the Sport/Touring tires from any brand that we have used during the last 15 years have lasted much more than 6,000km while touring and towing the trailer behind our CBR1000FS or the ST1300.
