My origonal post has slipped into the archives so here's the description of the vibration.."the vibration seems to be coming through the handle bars and im feeling it mostly on the palm of my hands. i can feel it changing from left to the right hand under braking but i also think its coming through the brake lever also. it seems to make a little 'ticking' sound also. It is only really noticable from speeds above 50mph. By vibration i mean it feels like im riding over small corregations on the road i guess??? i have the orage bearings installed also" I just got my bike back from the shop and they had put a new front tyre on it (Mezeler Sportec M1) and assured me that the vibration was fixed so off i go.. i do a couple of tests on the brakes at low speed and they seem ok then i get out on the motorway and the DAM VIBRATION is still there!!!!!!!!!!!!! having just paid for a new tyre and an hour and a half's labour for them to diagnose the problem, to say i was pretty ticked off is an understatement. I'll be ringing them up first thing tomorrow If anyone has any ideas they would be well received as ive just about had it with this 'bad vibration'. So far ive checked the wheel bearings, disk, disk springs, pads and wheel and so has the shop. I dont have a torque wrench so i cant go over the front end but this has 'suposedly' been done also Please save my sanity Regards morgan | ||

Neck (or Head) bearings my be loose. Might need to re-torque them to value. | ||

You can pull the clutch in and coast for a bit with the engine idled down to see if that affects the vibration. If it does, it likely isn't in the suspension or wheels, it is coming from the engine. Could be a failed engine mount (isolator). If the steering head bearings are loose, you can just clamp the front brake and rock the bike back and forth and feel/hear it. Good luck, Bill | ||

overtightened head tube (steering) bearings can cause problems as well. Do you, or the previous owner if there was one, do a lot of wheelies? Your bearing races could even be damaged. The best way to check head tube bearings is with bike up on front and rear stands. Look for slop in front end first, too tight or too loose can cause you trouble. Then turn steering head and feel for "notches" as you turn it. Hope this helps at least a little | ||

Check your tire pressure... When I had a new tire, rim and neck bearing done on my springer I had the same problem at roughly the same speed... When it was all said and done, the tire pressure was off... the proper tire pressure solved the problem  | ||

I am thinking it might be a bound/binding up front bearing on one side. | ||

If the vibration under braking gets worse the faster you go, and you're sure it's not a warped rotor, then check the front wheel bearings, I know you said you checked them but I had exactly the same prob with the orange seal bearings, I could feel they were rough when I removed the front wheel for a tyre change, and with the wheel installed and bike jacked I could just hear the bearings making noise with the wheel spun up by hand. The bearings were replaced under warranty but it took a lot of miles before the vibration slowly went away. | ||

ok i'll give all of these things a try, its gotta be one of them! I guess im a bit of a perfectionist when it comes to my bike (arent we all?) but this one is almost driving me round the bend Cheers guys for all of your input  I'll keep at it and keep you informed |
