Picked up a mint gsxr1100l today very happy with it forgot how fast they are lol just one issue at slow speeds it wobbles from side to side haven't had chance to look at it properly yet feels like it's coming from the front end the tyres are new can it be the wheel bearings?

Fish behavior riding headstock bearings too tide. Wheel bearings mostly guildy for unbalance on middle/ high speed

All those things that the others have suggested are good places to start but in my experience I found a cracked mudguard brace caused a shocking low speed front end headshake. Took me ages to figure it out. Bearings were fine. Underestimated what contribution that flimsy piece of 'fork stabilisation' has towards handling. And the bike in question? An evil TDR250. Scared me everytime I rode it until I spotted that.

hi pogger that's a nice bike ya got there ,its has to be bearings or tyre pressure ,the steering head bearings probably have not been greased or adjusted since the bike was new , check your tyre pressure first yoshi

Bit of a update removed the forks and yokes today the head race bearing on the bottom yoke had one of the bearings lose and it had worn into the yoke and frame this would explain why it handled like a back of shit anyone heard of this happening before ?

Jeezuz!, never seen that happen before... cheap bearings... or simply a badly manufactured one?, someone who didn't know how to adjust or maintain 'em correctly?, either way that could've been very fookin' nasty.. no steering anyone?

jeez pogger your not having much luck lately with bikes eh ,buy a lottery your luck might change ha ,,looks like someone tried to remove the bearings and couldn't after going mental with a hammer and chisel ,so just let them in ,hopefully a new set of steering head bearings will do the trick , yoshi

Looks like the race has been driven past its seat. The mark on the bottom of the headstock looks like it was caused by the bottom yokes lock stop hammering it, maybe from an accident where the bearing broke down. Even the bottom yokes looks like it grinded a little from the headstock touching. That would mean the bearings sitting too far up the headstock. smiley-shocked003

That indent on the underside of the headstock tube... is that a roller that's come out of the cage that's done that??? ....just been lookin' at the pics again and on pic#2, there's what looks to be a groove worn into the bottom yoke, defo appears to be roller sized... that must've locked the steering up when that came loose, surely. Just to be on the safe side fella, I'd have a good check around the frame in that area for any other accident damage

Thats what it is. Yeah looks like a roller indent alright. I thought it might have been from a bearing breaking down on full lock but it does indeed look like a roller popped out. The stem might not have been tightened correctly for there to be a gap big enough for a roller to fall through surely?

The stem might not have been tightened correctly I think that's probably what happened here fella. I dunno, the moral of the story here is if you can't do a job right then leave it to someone who can.... just goes to show that even on a nice, tidy lookin' bike.... bad things may be lurkin' beneath the surface... it's why I almost always do a strip and rebuild when I buy a bike. Just glad that Pogger found out about this before going out for a fast run smiley-sick030

Tell you what this must be the 7th gsxr I have purchased in the last 20 years and I have had some right dogs.
Having had a good look around I cant see any sign of accident damage or any other nnasties anywere so it looks like one of the bearings has definitely popped out and caused the damage. The stem nut under the top yoke was finger tight might have been why the bearing popped out in the first place. The races look ok so replacing the bearings and races should sort it just glad I got the bike home from a 75 mile run in one piece
