    For me the learning curve was how the Pirelli fall into corners without much pressure/input to the bars. I found myself cutting corners to close, and not needing to over steer.

    With other brands it was as though I had to force the turn, not just "fall" into it.

    Not sure if that makes sense, but now that I have 2,100+ miles on the tires, I can't imagine going to another tire, for anything.

    For those who may be interested:

    Put a set of these on my KTM1290SA last Friday. Travelled approximately 100km dirt, 300km road on the weekend and they are fantastic.

    These replaced a set of Pirelli Scorpion Trail II's and feel every bit as good on dry bitumen, much better off road, with only the very slightest increase in noise over the Trail II's, basically negligible.

    I originally had front steering wobbles on my 1290 between 60-80kph, and using the Pirelli Scorpion Trail II's amongst other things, I managed to fix this completely. The Trail II's were a great tyre. I got 12,500km out of them, F85%/R95% worn.

    The Rally STR's did not cause any steering problems whatsover. No steering wobbles of any sort, at any speed. I'm running 34PSI F, 40PSI R. Had about a 3-4PSI pressure change with constant running at 100KPH which is what I aim for.

    Love the fact these are V rated tyres (240kph), and I could quite successfully navigate 50km of 4WD tracks, then ride the bitumen home at above speed limits, without changing my tyre pressures.

    I also tried a set of Michelin Amakee Wilds before the Trail II's, but took them off after 400km as they were horrible on the bitumen. No steering wobbles, but the steering was way too slow for my liking. The STR's are much better, and only slightly slower than the Trail II's.

    If I can get 8000km out of these, and they handle wet bitumen suitably, these will be my new #1 tyre.

    How about in the wet? Here in WNC it rains a lot in the afternoon.

    I don't love the tkc70 in the wet.

    What about the Trail II in the wet?

    The Pirelli Trail II in the wet was excellent the way I ride and very confidence inspiring.

    As the majority of my riding is on the bitumen, if the Rally STR is no good on the wet bitumen, I will go back to the Trail II's

    Wet, cold, hot, snow and year round, the Trail II is pure sticky!

    Think you are still on track to get 4 to 5 thousand miles out of the rear?

    I'm confused about whether all the STRs are tubeless. The Pirelli website and Bike Bandit both list them as tube-type but I have seen them on the Ducatis and the sidewall says tubeless.

    I probably would have hit 3,500 miles, but nope.

    Huge, none repairable hole...

    First attempt, with four plugs, got me about 13 miles. Second attempt with seven, yes SEVEN plugs, got me another 5. Final attempt, another seven plugs, a half can of Fix-a-flat and some one inch gorilla tape, got me 17 miles.

    Ended up leaving the bike, dismounted wheel and took into town for a replacement.

    Well FWIW I now know unequivocally that the STRs are tubeless! I would have tried to break the bead and patch the inside. I still carry all that tube stuff.

    Glad to see you're using David Petersen's Cycle Pump. This now comes with a lifetime retroactive warranty. You may thank me for that upgrade :-)

    What's that muffler?

    Muffler came from the same place as the pump, BestRest. I have the Metal Mule pannier system, and the OEM muffler had to be replaced. I'm actually not sure what/who makes the muffler for them. In the picture you can see my retro fit exhaust shield/deflection attachment. I had a problem melting turn signals. It doesn't look that great, but it does its job well. Also after repacking the muffler, I couldn't salvage the end cap, so that changed the look.

    I will now be carrying a tube with me, as this is the second, none repairable flat in under two months. [​IMG]

    I've recently gone to the trail II tire also. For pavement wet and dry it is excellent so far. Hard pack gravel roads like well maintained FS roads it skates more in the front than the TKC 70. Also noted that for a given pressure and speed the tires warms up more quickly than the TKC 70 which surprised me. (I like the quicker warmup stickiness of the tires). Feels VG with confidence inspiring grip in heavy rain with two up riding.

    These look similar in design to the Tractionator Adventure tire...
    Are there any comparisons out there on these two tires?

    Personally I don't see the similarities, but the Motoz do not yet come in sizes to fit their intended market such as my KTM 1290SA, a BMW 1200GS, or the Ducati Scrambler they were made for.

    Pirelli STR - V rated - 240kph - tubeless in sizes to fit 1290SA (120/70/19 and 170/60/17)
    Motoz - T rated - 190kph - appear to be tubed tyres

    I would suspect the Motoz would be a much harder rubber as well to get a possible longer life.

    I suppose it all comes down to the use of your bike.
