Thats about right, the Dunlop's average about $20 less for a set vs the Michelin's.
I would have no problem using the Qualifier as my 208ZR experiences have been good. But after mounting Powers on my 900SS, I am convinced the Michelin's are better sport tires. I try not to push the SS too hard as the bike is cherry and a mishap would be very expensive, but I find myself riding harder than expected due to the confidence the Michelin's inspire. They are simply flawless.
Also my reasons for wanting to put them on the B12 are:
They have a pronounced V shape- this should help quicken the transition to full lean.
They are offered in a 120/65 front- I want to try this size to quicken up the steering a bit.
Either way, you can't go wrong.
Ride On, Ed.
