Suspension help. Lazy cornering.

right I went out tonight for a blast, the bike was doing it's usual tricks of sliding the back end in, on almost every corner which tb is quite alot of fun. When I decided to head home I slowed down and just took a bimble through the wolds.

I came up to a set of S-bends at about 30 because they are rather tight and I couldn't be arsed to ram it through them.

Came up to the 1st one, early braking, backed off to cruise round. when the front end just dropped and felt solid, the bike went striaght forward and across the other side of the road ending up in some old blokes garden parked on his lawn (He wasn't happy)

If this was the 1st time it had happend I would have put it down to me, but it seems to happen quite a few times. The worst was it throwing me through a hedge and across a court yard under the bike.

Any ideas what it could be?

Cheers

Tyre pressure or rider with an over active imagination.

I am been serious. This is what made me crash in 08 nearly taking my foot off. It just seems like the bike doesn't want to corner and decides to go straight.

ok... i'll rephrase my post

ever thought about trading the bike in for a safer working useable model?

What bike are you talking about by the way?

Not sure if I am missing something, but your problem is that the bike literally wont go around a corner?

How the hell does that work?

Please stop riding a motorbike before you kill someone, leave it to people who can ride round corners without coming off.

Have you had a look at your front forks?

I would check your fork seals and also try bouncing your suspension to see if you can feel anything odd.

Is there anything that has broken off and could have got caught in the suspension's travel? (this happened to someone else off here with a horn).

Were you braking mid corner? This will obviously shift weight to the front.

Either that or there's something wrong with your bike that is shifting weight forward such as your brakes, but I thought that would be quite obvious.

Hyosung front forks, by default setup has the wrong amount of fork oil in them.

Try setting them up, the rear shocks also have a habit of going...
Welcome to a cheap bike.

I had all sorts of problems on my GT, which shared the same rear suspension.

But get the forks reconditioned, and the rear shock checked and set up.

It could be extraordinarily fucked head bearings, but any moron with half an ounce of sense would notice that...

...Hmm.

I've only just heard about the fork oil. But as Marjay said

Hmm you think I haven't checked that? Along with tyre pressure and all the bearings?

It doesn't do it all the time just rare occassions.

I wasn't braking mid corner. I braked before the corner and aimed to just roll round nice and slow.

I meant dropped as the forks just drove down and felt like they had bottomed out.

Something definitely isn't making sense here.

When fork seals go, or fresh oil is needed, or springs/dampening knackered - things tend to get a bit bouncy - but bikes still corner, albeit in a pogo like affair.

Headraces will give a knotchy feel to the steering and can lead to understeer - but you'd feel this all the time and is easy to check with the bike stationary.

Are the tyre pressures okay?

Other than that, the only thing that has caused marginally similar symptoms in my experience is a lack of confidence on my/the rider's part. After a nasty shimmy or slide - especially how frequently they can occur over winter, it's sometimes difficult to notice that it was me who was 'locking up' and understeering - lacking commitment to a corner - by either not looking through a corner enough, riding with locked elbows, or just a little wary of counter steering the bike over, etc.

Easy to sort that when you notice that the rider is the problem, not the bike.

By all means, thoroughly check the bike over. But also, check your own riding - perhaps by riding a set route and getting comfortable that the bike is performing as it should, and you are comfortable on exploiting that performance. Doesn't need to be at speed either - a run around town is sometimes all that's needed for me to warm to a bike again.

iooi - The forks haven't dropped through the trees and the suspension seems to be working fine.

So maybe set up?

nasty - It happens on both sides with varying degrees from just a twitch to throwing me off the road (Oct 2008)

L-Jam - Good idea but my oil pick ups are at the front of the engine so it wouldn't last very long. Good idea though.

Could the oil been low or fvcked up be one of the problems? What effects does it have?

As far as I recall, suspension setup doesn't change by itself. And as suspension wears, knackered bearings aside, things tend to get looser/bouncier, rather than tighter/stiffer. Bouncy suspension would make the bike flop into corners - not really an understeer/running wide symptom, unless the rider's not liking what's going on and fighting it.

A similar trend occurs (with me anyway), on worn tyres. A 'step' occurs between the flattened centre of the tyre and the not so flattened edges. A little disconcerting sometimes as the bike suddenly steers a lot faster than it normally would as the tyre rolls over this 'step'. Again, something not attributed to understeering unless the rider intervenes and forces the bike up again.

If it was set up it would be all the time.....

All low oil or knackered oil would do is make suspension bouncy... It does not stop you from going round a corner.

Only 3 things would make you go straight on.

Steering locks.
Slippery surface.
Rider error.

But if its been doing it since 2008 Embarassed

Then it can't be a serious bike issue. As you would have been round more than enough corners for it to show up over and over again. Or you need to take a long hard look and wonder why you have not sorted it before......

I rode my GS for a week or two with shockingly unsafe head race bearings which certainly gave me a few scares on tight little turns. Can't say I ever had the bike go straight on and park itself on anyones lawn whilst leant over though. Are you sure Donkey Kong didn't drop a banana peel in front of you? Thinking
