Speed wobble and bad road handling?

[WULFSTAN]

I seem to get a bad wobble when I get to 80 and the bike seems to be all over the place. If theres a bump in the road my bike seems to find it, but the tyers seem fine. Bike is a zrx 1200r with 28k on the clock anyone any ideas? Ps i have a touring screen if that makes any difference thanks.

Check the easy things first:

Tyre condition
Wheel Bearings
Steering Head Bearings
Wheel Alignment
Fork Alignment
Wheel Balance (does it look like any weights have fallen off?)

Are the tyres a matching pair / are they inflated to correct psi? Have wheels been balanced?

If no joy with that, try checking front and back wheel bearings for play, swinging-arm bushes/bearings and steering head bearings.

If no good after that, might be worth having the rear shock looked at.

All assuming your screen isn't the problem, of course! Have you tried the bike without it on?

No not checked stearing head bearings by the look of things its going to be them or the screen. Would the bearings be fucked after only 28k ? Will try an have a look tommorrow after work anit really got anywhere to work on the bike which is a shame.

Are the 12 shocks the same as the 11? One of mine went at 16k and made the bike wabble.

[WULFSTAN]

I guess they're the same yes

If it is head bearings, then:

Lift the front of the bike, and turn the bars the should run smooth from lock to lock. Too many wheelies can crush the 'gates' holding them and cause problems.

A head bearing kit is normally around £30, getting a garage to fit them is very roughly another £100.

It's not a hard job to do, it's essentially just tapping bits of metal in and out of holes, but it can be a bit of a faff.

Thanks for the help lads turned out to be the screen took it off this morning before work no problems an i went up to 120 just to make sure
