Rear too light on ground

[wbks]

GSX-R 600 today, coming into a fairly mellow right hand corner at 190 went on the front picks quite hard, shifting down I wasn't engine braking too much, just tip toeing on the back brakes and the back "skittered" and fealt very light, really slighty (just noticeable) moves to the right before I eased off and rode it through. Nothing scary, but is there a way to stop this under heavy braking? I would think more rear rebound to keep the wheel as far down as possible, but then that would just move the bike even more head down arse up and make it worse? Any tips for susp. setup?

Use less rear brake? Supersport bikes do that. More rear rebound dampening will NOT help - this will cause the rear susp. to not extend when you brake hard, leaving it even lighter. Perhaps less rebound dampening will help. Be more gentle in your first brake application? Also, that feeling isn't a bad thing. As you get off the brake it will hook back up, ideally just as you start to tip in. It can help you turn the bike. All good on the track, probably not recommneded on the road. As you have said 190km/h I am assuming it was on the track ;) :whistle:

Thanks mate, makes sense. I might just have to beef up the settings evenly a few notches, and turn down rebound dampening to see how it goes, I'm probably a good 20kg heavier than the previous owner. Yea, I had seen it done before, but being my first "real" sportsbike (my old bike sure as hell didn't have brakes like this!!!), she brakes pretty well! Going easier first braking could probably help, too. Still getting used to how touchy they are, too haha

Found this to ba a bloody good site for helping with getting ya sags and set up right !!!
Sounds like we'll be seeing ya at the track (cough) more often aye ?

Believe me, as soon as I can afford it, I'm there! Thanks for the link

In order to put more weight on the rear wheel:

EAT MORE PIES

Try same corner at a decient pace next time.

I had this exact problem with my new bucket, except the back would lift right off. The cure was another turn on the front fork cartridge emulator preload springs thereby increasing compression damping. I'm thinking this is the problem as you do mention how you got on the brakes hard initially. The bike would have dipped in the front, or rotated about the centre of gravity. Once the forks finished their rapid movement the bike could have continued to rotate with the result the rear would have got light or even lifted off. If you can control that initial rapid fork movement you may find the back doesn't get so light just as you get on the brakes.

Try a bit more front fork compression damping.

Easy! Just mono on your front tyre around the corner! And film it for us:2thumbsup

hey bro i had it set up hard on the rear for the track and racing but you just need to make the preload softer. it had no prob with it on the road but that cuz i went a bit too fast lol. kinda like jay step it out on the corners is our style but yea owell got see robetert taylor or bring it over home and ill get it set up to you and front springs maybe to heavy for you

[wbks]

I duno dude, as a bit of a fatty I doubt the springs are too heavy for me. Probably riding a lot slower on the road than you, though. To be honest I didn't have any complaints with the way it handles at all apart from the back skittering, and maybe I should just accept it when I brake harder? Haven't had any problems with it before, and its on new M2's, so it was probably just grabbing the brakes a little hard. Got a little surprised how fast that corner came up hahaha

yea its geared down real hard lol so will pop through the gears lol. um just gas it hard and slide it through

Don't for god sake let him near it lol
If ya gonna go anything, do like Jay said and back off the rebound in the rear just a little at a time !
But like ya say, On the road it sounds like it's fine ! It aint often ya get on the brakes that hard, anywhere other than the track !!

Wait until you meet a camper-van mid corner at that speed ..........:Oops:


Brake first - power out.

Hey Mate, it's like the mrs ex is a lovely bloke, but would i leave him alone with her ?

Lol still think you were mad to sell it !

Does the speedo read off the front or rear on this bike?

off the fear box

Brake first - power out.It sounds bad but I don't do that often...


yea its geared down real hard lol so will pop through the gears lol.fuckin right...

[wbks]

off the fear boxwhat?.......

[Sidewinder]

what?.......

gear box drinking lol. kinda my weekend now maybe

[wbks]

So the gearing doesn't mess with the speedo? Then what's with it reading out almost 270 with plenty of revs to go? I mean, I had the PC3 in it, and its got a yoshi can, but I'm pretty sure you'd be lucky to get that... Troglodyte... lmao

Lol. Be one bloody quick 600! If its Sidewinders old bike there's no slipper clucth so you could have been having wheel chatter through the drivetrain. Try and feather the clutch more as you let it out, and make sure your blips on the down change are PERFECT - or you will get this. I had a K4 750 on track for a season and it was a pain becuase of the lack of slipper clutch. Once you have ridden a bike with one - you won't go back! :)

If your rear light is on the ground, you must be doing a wicked wheelie man :2thumbsup

[davebullet]

do you ride with your nads against the tank? Push your bum further back to put more of a lever on the rear to plant the tyre.

:lol:
