Good morning all from Canada.
Thought I would add my 10 cents worth to this conversation. Took delivery of my Z900RS in June 2018 and from the very first day, I had doubts and a lack of confidence in the OEM Dunlops.
I found this forum and was doing my homework on replacement tire suggestions with the intent of changing out the tires at 8000Kms. At just over 6000Kms, I picked up a nail in the rear and not wanting to plug repair it, I decided to change out the tires at that stage.
I choose to put on a set of Michelin Road 5's
All I can say is had I known the difference these tires would make to the handling and performance of the bike, I would have replaced the original tires at 150Kms. NIGHT & DAY improvement. Gone are the tar line wobbles. Gone is the feeling that the rear wants to step out under duress. It honestly feels like the bike can be thrown around much easier and with total confidence. I haven't compared the profiles of the OEMS and the Michelins, but the new Road 5's appear to allow the bike to move back and forward from left to right with much more ease at any speed and any type of corner.
In the wet (limited exposure so far) they again inspired a lot more confidence than the OEMs. More banking angle, more speed.
And this week, with temperatures soaring ( 30-36 Degrees C), I managed to get in 350Kms+. The tires again performed exceptionally. No heat degradation, no squirming and again just a total increase in rider confidence.
Maybe the OEMs issues were batch related, maybe its a combination of rider style/climate/road temps that cause such a variance in opinions, I don't know. But all I can say is my Z900 is handling the way I always hoped it would with the addition of these Road 5's.
Safe riding guys!
