Got around to changing the front tire. 2007 Reflex with OE Bridgestone tire, @ 8k miles. Some tread left but feathered wear so what the hell I'd change it.
Got a Michelin Power, identical size 110/90/13. First couple days of riding were rain days and all seemed fine.
Today's commute was hot & dry, so at 70mph and above I find that the front end is dancing, and not in a good way. The bars gyrate back and forth. It seems to be set off by turbulence or by bumps in the road. The faster you go the worse it gets.
The thing is this never happened till the front tire change. Anyone had this result after a new front tire change?
Checked to be sure the tire direction is correct, and the ballance seems ok, but not checked on any machine.
