gsxr 1000 has a bad vibration from about45 mph and uplike a tire out of balance, put new tireson it, changed out bearing, rims, forks, rear shock, spockets,chain, swingarm, still there any help please!
Does it do it when the bike isn't running ?
Coast it down a big hill . . .
Does it feel like it's from front or back? maybe check steering head bearings if from the front.
i think it does come from the front but i dont know whatelse to check or to look for, im going to try putting it on a dyno to make sure its notcoming from the back.
Check tire pressure could be over inflated or vice versa
Is a rim bent?
Do you have a computrack (laser frame sighting/straightening) center near you? Try them to see if your forks are uneven height or twisted in the trees - especially if you lowered the bike. If it's coming from the rear try replacing the sprocket hub bearing.(only because i had that problem)
