yep they have full adjustment... cept I don't know how most of them work...

front preload is on about 3~4 out of 7

3rd August 2005, 00:23

Cool then, I did mine but it is suited to me so take a look here (http://www.uponone.com/howtos.php) for a decent easy idea of adjusting (3/4 pdfs), I was having the same problems as you...
Have you also checked your tires?

Zapf

3rd August 2005, 00:27

yep... right on factory recommend PSI...

is it unstable up front or back?

front... also feels the bike is tipping in too fast..

I assume you use recommended width tyres??

also feels the bike is tipping in too fast..
obviously you are going too slowly. I recommend speeding up. :yes: P/T

Tipping in too fast compared to what, Felix? Have you got generally used to the bike yet?
Sounds like you need to get the bike set up for your style of riding.
Thats a can of worms , in itself, if you dont know what you are doing - -need a suspension set up expert - any out there?

3rd August 2005, 07:12

You didn't say what you were riding before or how long you've had the Gixxer. Tipping in too fast sounds like the bike might be a lot faster counter steering than what you are used to & that as long as the tyre pressures & the suspension ok, it may be putting in some ks to get used to your new ride :ride:

mate, it is a racebike with a number plate, but you knew that when you bought it didn't you?. now you have got it you have to come to grips with it. it's not built for soft arseing around it's built to go hard & when You go hard it will all make sense.
i should add... don't rush out & try to go hard if you're not ready.. good luck

...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?
...
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...

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.

3rd August 2005, 08:40

Zapf, this is a normal feeling when you first start riding a bike like yours. I felt exactly the same when I first jumped on my bike after a lay off.

Now for the cunty bit: Not quite sure but I think you've only done 2000km? since buying your bike. For fucks sake mate, you'll never get used to it if you don't spend some real time riding it and exploring it. Get to a track day, who cares if you're wombling around, and do some laps, consistantly annalising your riding and the bikes handling.

The feeling you are getting is due to the fact you're not used to having that much weight on your wrists when cornering. The only way to alleviate this, is ride more.

Don't touch the suspension unless you KNOW what adjustment changes what.

more hp than your 750 eh?...

Stupid question - you're taking the piss, eh?

Zapf, remind me next we go on a ride, we can play swapsies (with the bikes!) - see what a slightly older (Y) 750 with the back jacked up and the front dropped feels like to corner.

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.

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!

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.

3rd August 2005, 12:24

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. :o
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!

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.

Toast

3rd August 2005, 13:18

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..

So you can corner it with stability if you are in a bit of a race position...clearly a design thing then (though we can all benefit from suspension set-up)

Being down in that position just gives you the ability to lever your strength on the bars (which turn the forks, obviously), properly. If you're upright, you can't exert proper force on them, and they'll move around and do whatever the hell they like. Poor explanation I admit, but read a Keith Code book, helped me heaps :)

So let me get this straight:
1. You're having handling/cornering problems with your 2005 GSXR-750
2. You maintain that it's a better performing bike v. an 05 636
3. You would readily compromise this better performance for $$, to go to a "worse" bike than the one you are having problems with?
4. You also bought another bike, while waiting for your GSXR-750 to be repaired from crash? - is $$ really an issue? I can barely afford having 1 bike :no:

Someone mention my name....yeah thats right trev, i had been toying with the idea of having the suspension set up properley, so i took it to Scott at cycletreads, one of his employee's/contracor's? set it up last saturday. Now it did'nt feel a lot different at low speed, but once it gets going....well it feels more confidence inspiring [ i am a slow rider with plenty to learn].
But to be honest riding with KBers is improving my style a lot more than any other factor...loosebruce said to me a while ago 'just ride it' wise words Bruce

I don't geddit man.... :wait:

when I did take a 636 out for a ride yes I agree and granted that the 636 was a easier bike to jump on and ride. That much I'll agree :)

I dug high and low and even under the bed for money to buy the 750, yes call me nuts... as I have for the last year...starting with the NEW VTR250 in Aug last year... and yes... I had to made do without other things. In a way I paid for it.... retro spectively looking if I haven't bought the 750 and a 636 with under 1000k's was available for 13.5k I would have bought the 636. But now that I have the 750 I won't be swaping it if thats what u are saying... while the 750 was in repair I bought another bike yes... I always had a plan for that... the 750 wasn't that great for commuting and I do need a way to get to work, so a used CB400 was great for that. :) can you blame me for missing something on 2 wheels :yes:

At the risk of sounding brutal, the major problem is rider confidence and ability, The bike is indeed very capable, is fairly new with good tyres, it is also a cutting edge sportsbike and regardless of weither the suspension is set up perfectly or not you would find it makes a lot more sense at highly illegal road speeds........try group riding preferably in the dry to begin with, latch on to the back of a good rider and copy there lines, keep your head up looking towards your apex'es, a light grip on the controls, and get some miles under your belt, drive it everyday..........you'll get there
