Ok you racers.
To take a bike from the road to the track what is the general idea with suspension adjustments? Rebound, compression, and preload. More, less etc.??

Taking the bike to Puke on Sat.

is it worth the trouble? By the time you get the settings right and comfortable riding it, the day could be over. Would have thought you'd have more fun hacking it as it is..

could (and probably) be wrong..

Just worry about tire pressures...suspension shouldn't matter too much given you are going to ride it there and back anyway. If you ride hard on the road - the track won't be that different in set up.

You could try setting the bike up to take right handers better!

Track isn't usually as bumpy as the road. If it's hopping and skipping into corners knock a bit of rear rebound off, otherwise it should be fine.

riding at the track will highlight any suspension problems. but its hard to say what to do until you find out what its doin. are you takin the R1, they are fanbloodytastic straight out of the crate. leave it, drop your tyre pressures (30-32PSI at a guess)

Yes I am taking the R1. Standard tyre pressure is 2.9 rear 2.6 front (god knows how many PSI that is) so what do you reckon for the track?

psi kg/cm2
10 0.7
15 1.1
20 1.4
24 1.7
26 1.8
28 2
30 2.1
40 2.8

Those pressures seem very high indeed >40psi rear and >35psi front

Those are the pressures, as confirmed by the dealer.

swan--ill be there with mella yella running in the new to me motor. Expect to lap me at least 4 times in the first session. I might be quickish in the corners but SLOOOOOOW in a straight line
If it were me i'd leave the suspension well enough alone for the moment.
Ill have all my tools there so if ya wanna stuff around between sessions you're welcolm.
I gotta tell ya -Pukie is a bit of a goat track at the moment

my handbook for the 636 reckons 36/42 f/r. I tried it at that and it felt a little too hard and skitish, so I run around 34/38 ish.. still experimenting with it tho, might do it at the track..

Swanman - a good place to start with tyre pressures at the track would be 2.1 (30psi) Front and 2.2 (32psi) Back. Thats what I ran on my R1 at Taupo :niceone:

Jeez that seems quite low, I assume they hold their shape at that.

I think WE should listen to the manufactureres... I run front/rear at 36/41 PSI, so around the same as you. I must admit it feels very unsettled in the corners (on normal roads), but I'm not sure if thats the bike's suspension (I'm much heaver than the standard 65kg jap rider), the tyre pressures or just me as a very inexperienced rider.

On the street I keep the TL at 36/36. For the track I have it at 32f / 30r.

I sugest leaving it alone. I only change mine when something annoys the bejesus out of me. Then I find a short time later it normally ends up back where it started from.

you need to lower the tyre pressure at the track because of the increased loading it generates more heat, more heat increase in pressure. if you leave the tyre pressures alone your bike will slide all over the place when the tyres get hot.

Thanks. I acutally did lover the pressures about 10% and the tyres did very well.

For a long time i had just ridden any bike around Manfeild (feilding), on the standard pressures. VFR road and race, ZXR250. Best i think is to start of standard or a setting you use for the road and just turn up and ride the first session like that.
Take not what they are and adjust to what feels good.
My nc30 on the road ran 30f and 32-33r i liked it that way, but when i started racing, even with road tyres to start with they went to 30 a piece.
Dont know if that helps anyone? :mobile:
