    (POST) Rear tire size VS Handling

    Now that my first season with the Kat is over, it's time for new tires, and I am going to go with the Michilin Pilot Road tires. They have good reviews, and I currently have a Pilot Power on the back and love the way it grips... but moving on to the question:

    I read this web page about the POST katana rear tire size and handling: http://www.motorcycleanchor.com/Katana/kat_tires.html. I do mostly highway miles with some back roads here and there, but I am still a novice about understanding motorcycle physics at the tires grip limits (this is where I need help). My current tire size in the rear is a 170/60/17 (mich pilot power, came with the bike), though the oem size is 150/70/17. The grip is really good (which I can attest to the rubber compound), but according to this website, the handling should be worse than the oem size. I am looking to improve my riding skills, and don't really care for the fat tire look.

    Since it's time for new tires (going to go with the pilot road, F&R), which rear tire size should I go with: the 170/60 or the 150/70??

    Thanks

    160/60
    90% of motorcycle forum members do not have a service manual for their bike.

        Whichever size, go with the PR II's - after trying Dunlop 205's, Pirelli Stradas, Metzler Z6's - the Michelin PR II's have incredible grip and thus far (6K miles) great tread life. Oh, I run stock 15/70/17 and once in a while 2 up with no issues at all.

          I have over 10K on mine with absolutely no issues and barely any ware!

          Except they are useless on wet grass, mud, sand, snow, ice, etc.

          But don't let that stop you
