I had new tires installed (cheap Continentals) and since then noticed my handlebars slightly vibrating at 35 mph. If I let go of the bars, it's a minor head shake. More air pressure helps but still there. Local shop checked out my front end and tightened everything, etc.... and released it. It still does it.

But goes away at speed. I need to get it up to 100 or so and let go of the bars, but still very concerned over this little low speed wobble, like it's searching for something. Any ideas?

I use Conti Sport Attacks ( cheap) and I don't have any wobble or shake.
Maybe check your wheel and steering head bearings.
And I love the tires.

Mad

My front end goes something like this:
Once the the repacking is done, I assemble the upper and lowers. You can choose either fork, but I start with the left fork. You can measured per spec, or rematch the patina v. clean area that is not pinched, and that is right under the triple tree.

I now float the other fork. I install only the axle, and run the right fork either up or down to where the axle finds the best static spin into the left fork. Tighten the pinch bolts and recheck. Lube the axle so heat/condensation does not rust lock the center collar. If the axle lines up and threads so easily, then you roll the wheel in, eyeball where it lines up, it goes in by hand is the float... no hammer is ever used on either axles. If you saw them take a soft hammer to the axle(s)... calamari at work.

With all wheel spacers out, calipers hanging away from the forks, I now install the wheel. Once I let go of that wheel it should not move. I run a piece of tape at what ever clock position. I now check the guy's balancing work by grabbing either the 9 or 6 o'clock position and place it to the 12 or 3 o'clock. Meaning, I want to move that one tape to the other 3 positions; where it should not spin, nor move once you let go x's-4.

Recap:
You know the front end is not it when...
You know you squared the tripe tree in a static position.
You know the air pressure is well over 35psi, and the balance is spot on.
You have to look at the set marks being at least even at the real adjuster marks.
You now have it traveling as a straight arrow; having the rear pointed straight, the front end won't drop weird to one side, normal on the other side, or the one leg being pushed up to install the axle.

Nothing really to do with setup here,but if she's wiggling at low speed,I'd damn sure be cautious of getting into high speed stuff.Until you figure out where it's coming from.IMO.
A wobble can happen so fast you don't expect it,then boom.

I ordered Pirelli Angel GT 2 A spec today. Heave carcass. And check the chain and go from there. All else was already done at a shop, so I'm hopeful it's really the tires now.yellowduc@peoplepc.com

I have tried a few different tyres on the ZX14 and found the Michelin Pilot Road 5 the best for feel, stability and wet weather grip. Fantastic grip in the dry as well but not up to the pure sports tyres.
