FZS 600 Oversteer - spoonlamp - 12-11-12
Right. I've replaced my written-off red FZS600 for a beautiful silver FZS600!
Only negative I can find with the bike so far after a week of riding is that it steers strongly into the corners. My last one you could practically go round with your hands off the bars but this one I'm having to counter-steer quite a bit.
What would be the cause? Has the rear suspension been raised or something? Anything to do with front forks?
Thanks in advance to any replies.
EDIT: Thanks for moving this to the correct section of the forum
Re: FZS 600 Oversteer - caretaker - 12-11-12
some people fit jack up kits which would make it steer quicker. there is some info quite recently about how long standard dogbones should be. do a quick search for jack up kits.

Check the tyres. A squared off rear makes it harder to turn in.
Re: FZS 600 Oversteer - His Dudeness - 12-11-12
yeah could be old or oversize tyres
Re: FZS 600 Oversteer - CRH - 12-11-12
ime with the dude on this one
...check the size of your front tyre!!....should be a 110/70...anything else will/can cause you probs?...if your doing lots of counter steering?..mabe you got a 120 on front???? :rolleyes
Re: FZS 600 Oversteer - markbubble - 12-11-12
as already said,jacked up rear,stiffer rear spring(or set stiffer) lowered or softer front forks,tyres different sizes,brands or pressures to what your used to i changed tyres on my last bike and bike felt totally different even tho were same sizes and pressures
i prefere bike to be quick into turns rather than muscle it around but thats just my personal choice!
Re: FZS 600 Oversteer - Skippernick - 12-11-12
When i changed from a bridgestone bt45 tyre to bridgestone bt23 i had to stiffen the front suspension because the bike turned in too quickly.
maybe your problem is in reverse, do/did both bikes have the same tyre?
Re: FZS 600 Oversteer - darrsi - 12-11-12
Yeah, my immediate thought was a 120 front tyre!
Re: FZS 600 Oversteer - unfazed - 12-11-12
Check the tyre sizes front and rear.
They should be 110/70 * 17 front and 160/60 * 17 rear
Re: FZS 600 Oversteer - spoonlamp - 13-11-12
Thanks for the responses guys.
Front tyre is 110/70 (Battlax BT020) Rear is a 160/60 both are in good nick, no squaring. I had a quick look at the suspension and it does look like maybe it's been let out a little. I'll try and tighten that and see how much difference it makes.
Thanks for replies.
Re: FZS 600 Oversteer - darrsi - 13-11-12
If the fork oil levels are wrong that can cause unstable steering as well.
Re: FZS 600 Oversteer - unfazed - 13-11-12
Tyre Pressures?????
Standard is 32/33psi front and 36/37 psi rear
To soft at the front can cause similar symptons
Re: FZS 600 Oversteer - His Dudeness - 13-11-12
have you got a fat bird on the back? that'll lighten the steering :lol
Re: FZS 600 Oversteer - spoonlamp - 14-11-12
Tyre pressures are all good - looks like it's just me. It's my second Fazer so I was assuming it would be exactly the same handling as my last. Think I just need to get used to it being a little more twitchy cornering at low speeds...
Re: FZS 600 Oversteer - Dead Eye - 14-11-12
Unfortunately no two vehicles (same make and model) are the same - I've had two Mk 2 Golfs and they were ridiculously different despite having the same engine and gearbox and I even swapped over the wheels / tyres
Re: FZS 600 Oversteer - His Dudeness - 14-11-12
are the front forks dropped a small bit?
Re: FZS 600 Oversteer - darrsi - 14-11-12
I'd still check the fork oil....... :rolleyes

would be a bit awkward to do though wouldn't it? he'd have to take the forks out just to check the oil. if you're going down that route you might as well replace the oil
Re: FZS 600 Oversteer - darrsi - 14-11-12
Yeah, if you've got it apart, which is a bit of a pain, then you may as well change the oil, but then again the bike is new to him so maybe there's no record of when it was last changed so it's one of those jobs to get out of the way, especially as there is an issue with steering anyway. If it's not that, then at least you don't have to worry about the oil again for quite a while, and you've also eliminated that as the cause.
The reason i suggested it was because i bought a Honda off a workmate years ago who didn't live too far from me, and when i went to go around a roundabout i nearly dropped the bike because, as i later found out, the levels were totally different in each fork.
When i mentioned it he said he never felt anything wrong? :rolleyes
Just a thought.......
Re: FZS 600 Oversteer - spoonlamp - 14-11-12
Thanks for those suggestions - I'm probably going to get the oil in the forks changed (or replaced) to 15W anyway, see if it takes any wallow out of the front end on braking so it'll sort that out. Not sure about the forks being lowered, I'll need to find out what they should be and get a measuring tape out I guess! lol
