I will go one the record both personally and professionally (BTW I'm a surgeon)
The stock 'stones' were crap. Hard, slow to warm,. squirmed and let go at the wrong times alot like dunlops. I know that I will catch flak for this but my opinion is my own. I have been riding since street since 1986. Tires have improved greatly over the years but the fact that major manufacturers still sell new bikes with crap tires is only a testament to two facts.
1) Crashed bikes generate tremendous revenue for repair shops. FYI, about 50% of all motorcycle dealer revenue is from service!
2) Corporate liasons exist and Mother Yamaha is in bed with Bridgestone and Metzler, who currently make tires that shred from the inside!
I have run literally every major brand on one bike or another over the years. I did love the Sportecs from Metzler for my R-1 but they wore out so damn quick.
I have enjoyed the Avons for sport touring on R-1s, FZ-1s and now the FJR. Little cold at first, which makes for a cool spinning tire down the street!. They stick well, wear like iron and I have never had a case of the dreaded "shakes" with them. BTW, I have owned bikes from all the major manufactures, but Yamaha has a special place in my heart. 2nd bike was a 1987 V-Max!
I will admit that the next pair for the FJR will be the Pilot Roads. Gotta try them out.
The stock 'stones' only lasted 2000 of spirited yet reserved riding, they failed to inspire confidence and slipped occasionally. The current Avons have 3700 and show some good wear, maybe another 1000 then they will be very dead.
Opinions are personal and if you don't agree with me, then that's fine. Every rider is different and this is an 'Open" forum. I also own an 05 K1200S which I do love.
Waiting to pay cash for a new FZ-1 in a few months. Wife wants me to make some room in the garage before I get yet another bike. So my Duc is being sold!
There's my 2 cents for the never-ending thread! :bleh:
