GSXR handling.... help.... (wisssss)

[crazylittleshit]

Should of got the 636, I have no problems with steering. or leaning. But I dont ride it the same as I rode the FZ6. Different bike calls for a different style. But Ill leave it to the more qualified to help you out. As I dont know bugger all.On a side note have you checked your front tyre preassure.

Don't you find it needs a steering dampner?
Mine gets a bit twitchy in the front under power when it gets light.

Not since I set the rear sag. Still is the odd bit twitchy but alot better than when I first got it. All the gear on I weigh in at close to 90-95kgs. The bike from factory is set for 60-70kg from memory. Its in the owners manual.

May still look at one but not as concerned about it these day. Taking into account how I ride as well. I aint no speedster.

right.... i hav a 05 GSXR750.... and I have something with the handling / riding position...

I find that I can't corner / lean the bike stablely unless I am tucked in almost flat on the tank, eg. with your arms proped up and sitting more up right cornering and leaning feels unstable.

Would this be a bike design ~ riding position, center of gravity / turn thing? or something else... ? and perhaps would handle bar raisers be in the right direction?

Or its just me needing to get used to it?

tkns in advance for the suggestions..

mate bad news. your bikes just no good.\
\ pack it up an send it to 54 waiwhetu drive wellington. all problems sorted

Basically to be perfectly honest, I don't know a LOT about suspension set up. I just know the very basics.

With my GSXR, it has a front end set up for a 100KG dude, while I'm a 65KG dude. Same with the rear shock before I got the Ohlins myself. I know I haven't come 1st or anything in proper F2/F1 meets but at times I have held my ground OK, with some tough compition with full mods and pro setups.

As it says in twist of the wrist, different bikes will have different setups and charecteristics. You just adjust your riding style to that and just well... ride it.

Next bike I get for racing, I will try to buy a new one and the leave it all stock. If I am an OK rider I should be able to race it well with out any mods as these new bikes are already desgined very very well already, even for competitve racing let alone road riding.

What I am basically getting at is that, I do not think a K5 GSX-R 750 will have handeling faults. You basically need to get used to it. As Dave said before, it is desgined for racing and the faster you tip in, the faster you can get the cornering job done. Which is the primary goal for racing. Rossi (if you watch him on TV), tips it in quite very noticebly a LOT quicker than anyone else in Moto GP. It almost looks like he is dropping the bike like a rock to crash it, but he knows exactly when to stop the tipping in and hold his posture. If you were in Paeroa, you would have noticed Craig Sheriffs do this as well through the esses. He is noticebly quicker at dropping it in than anyone else as in the NZ feild. So yea, tipping in quick would be the bike's charecter. If it's giving off mad tank slappers, THEN it's over the top.

Saying that, tire pressures and shape do add to the tipping in fast or not fast enough situation as well. However if your front tire is new with the correct size and profile and you are running it between 29-36 PSI, it should not be the cause of the problem.

Heya Zapf,

granted my GSX-R750 is ancient (1996) compared to yours, here's my $0.02:

* quick steering is generally considered to be an asset for a sportsbike

* how quickly a bike leans can be affected by any of the following:
- tyre profile (many racy tyres have a pointy profile)
- tyre wear (if you do a lot of leaning your tyres get pointy,
whereas if you do a lot of commuting your tyres get flat)
- chassis geometry (this is a complex area as changes to tyres, suspension
etc. all affect things like steering angles)

* what you are experiencing seems to be a lack of confidence in the handling
of the bike. This can be overcome with time (i.e. familiarity with the bike)
and improvement of riding technique.

* do you bend your arms when cornering? It is essential to bend your arms
(at the elbows) all the time when riding so that you can counter-steer
properly. You also want to make sure you're relaxed.

* the GSX-R750 is supposed to be (and is, in my opinion) one of the best
handling bikes ever built. Once you click with the bike, you'll agree too!

PS: raising the bars/clipons would be the opposite of what you want to do to improve front-end feel. You want more weight on the front when tipping into a corner (braking helps here too), not less!

Just ride it.....

[Zapf]

you are probably onto something there zapf. Do you think this design fault contributed to you lowsiding the Gix? Perhaps the excessive mid range torque through the back makes the front too light and unpredictable? So it wasn't that spot of oil you found on the road after all?? That's a relief, because your crash post was getting me scared of the state of NZ roads.

Sorry 750Y - gotta disagree with your thoughts: how much you know about GSXR750s anyway? I don't think there has been enough developmental history with the GSXR750, so they haven't got it quite right (yet).I don't think they put the best components on the lower bikes in the range, so the handling on the flagship K5 1000 might give you more joy. It'd be OK, you just adjust your throttle hand to suit - and anyways, the Thou is not many more hp than your 750 eh?

The last thing I can think of to help your top end vagueness is to source the best SBK spec Ohlins forks, or equivalent to whatever they use on the current Alstare Suzuki team (Corser and Kagayama). Knowing you have the best should help your confidence. Selling your Skyline would help towards making your Gixxer the best bike on the road.

Actually now I think about it, my K1 750 ended up with a front end handling problem too...

ah ic... so you can't ride a 750 for hence you swapped for a 636? at lease I am asking questions before I have a negative castor too

I dont wish to come between you 2 love birds, but those seem brave words from
someone who is having problems cornering and just had his bike fixed from a drop. Both of you kiss and make up.

[Zapf]

thanks everyone.... that makes a lot of sense.... since its my 1st real sports bike. And it comes with sports tires... BT014.... it make sense that it does corner lot faster than my past bikes...

I think sometime I'll enlist u guy's help in setting up the static sag... that should be the lease I can do.

and yes... I have done all of 2000k's on the bike

The sag is easy as pie to set up. If you want to know what other settings to make, one of the online M/C sites has their recommendations, which are a good start, even though they're a bit on the sporty side:

nup, riding my Gixx never made me feel like puking. If yours is, I'd suggest that may be influencing your cornering ability.

... if I didn't own a 750 I would snap it off you quick smart!

So you do like the 636? Me not understand.
Maybe we should swap? I haven't really ridden a 750 since my K1. They are the same OE tyres, so that could be a control element of the experiment, and my suspension is the same as Mr Kawasaki set them. AND...mine's got (unused) crash bungs already!

[750Y]

...Sorry 750Y - gotta disagree with your thoughts: how much you know about GSXR750s anyway?

lol, too true, i should not be giving any advice as i don't even HAVE a bike 8-(.
what a tosser huh.
get stuck in there Zapf! it will come right & your confidence will grow...

I think 750s are to big a bike for small asian boys like Nhuanh and you. You should buy a smaller bike like a 600 thats why I ride a Hayabusa. If your going to keep riding it make sure the springs rates are suited to your weight. I could give you the rear shock from my bike to try when Colemans get my leaf springs in from back order.

Yea the 636 is a good bike.... but the 750 better... however for the money... if its a 750 for 17K and a 636 from deb's for 13.5k then I'll take the 636 thanks.
