Thanks, Two Wheels. It seems to be MPH affected, no matter the gear.
I loved this bike before the stock tires were swapped for the Shinko 705's, and shortly after I noticed this vibration. I think my confusion stems from the fact it does not seem to be tire related per se, (pulling in the clutch, it smooths right out).
I have had the chain and sprockets replaced and two different shops looked at it. I would think if it was tire related, it would be across all gears or RPMS, but is not. (This is my first motorcycle)
It could be just as you said, a certain resonance from those tires. Further adding to the confusion is the testimonial of every other rider on 705's who love that tire.
I guess the only thing next to do would be to try a new type of tire, and see if that resolves it. Yes, Life is short, but money is even shorter. :-)
