What makes my bike slide?

[ryanf062]

:ride:Im having a lot of trouble with my bike sliding at either end and i am not really going that fast round corners when it happens. ive tried changing tyre pressures to get the tyres hotter but the front didnt get much heat in it at all. does any one know any possible reasons for this?

[Pumba]

What tyres are you running?

How old are they?

What pressures were you running and what did you reduce them to?

Whats your suspension like?

Are you lossing the front then the rear or the rear then the front or both at the same time?

+1... what he said.
I'm putting my money on suspension :whistle:

+2 but i'd be betting the tyres are old and hard as nails

An RG150 shouldn't slide without a great deal of effort.

If the tyres are correct and for the road, I agree that your dampers may be screwed.

[nodrog]

black ice, gravel, or vegetable oil are the top 3 suspects around these parts.

+3, I'm with sinfull on this one...

When I had my RG I bought a chuncky looking Dunlop hoop from trademe - It was hard as nails, but was fine for my day to day commuting. It was easy to slide and squealed like a stuffed pig at the slightest pressure - So, you may have a couple of original Dunlops on your RG? If so get rid of them fast.

Also tyre pressure is important, too soft and she will slide. No idea on what the manufactures recommendation was but I used to run mine at about 32PSI

With half good black pits on the RG should be super solid through the corners, pitch it over and enjoy the ride :banana:

[FROSTY]

whats making it slide?--YOU .
RG150's seem to reward a smooth riding more than say a Hyosung or any bigger /heavier bike does



Covered off above are the two other possibilities--shit tyres and or bad suspension setup.

Streetstock or bucket?
If bucket what bucket, engine, tyres track etc..
If streetstock are you talking about taupo? That was a particularly slippery track.

In winter I run really low pressure on the track, around 20-25 PSI and that seems to work about right.

I'm on Dunlop TT900s, the other option is the Bridgestone BT39 SS.

Other tyres in this size are not designed to be grippy but have low price and high milage as their main goals so aren't any good once you start to push it.

Dont run anything else on a streetstock because you are going fast enough for the tyres to matter!

If your talking about bucket racing your on roys hill right?
I found a few of the corners there got the rear of the FXR sliding when it would be fine on our local tracks so setup for that track may be quite particular.

With an RG there is really nothing you can do about the suspension but it doesn't matter as much anyway because the tracks are much bigger than in buckets.

For a bucket it really could be bad suspension and the answer to that depends on the bucket, suspension and tyres.

Another thing is I found I got to a point where I slid alot and couldn't go any faster until I got much smoother and that allows you to use more of what the bike has got, I think this learned ability is what sees people like Fish, Sully, Bayden, Geln and Dave going so much faster than most others.

i should have mentioned its for my bucket that is an rgv150 frame with a g145 motor and the tyre are dunlop roadmax and ran pressures at 18 and 20 is that to low and the reason for the sliding even though the front wasnt particularly hot. form what ive herd less pressure = more temp is that incorrect?

[bucketracer]

When I had a problem with sliding; I was leaning the bike over to far and riding off the edge of the tyres. The sliding stopped when I learnt to hang-off and keep the bike more upright in the corners.

Ahh, RGV150 (unlike the RG150) have ridiculously skinny 1.4" rims so most tyres are probably oversized so likely a nasty profile that drops away. You should have say 2.5, or maybe 2.75" tyres, but you are probably running 3" or 90 which will be a problem.

This is where I suppose you say you have different rims. Type some more at the start. Are the tyres new, how big etc etc.

[SHELRACING]

F5's hit the spot.

If I were you, I'd start right from scratch, Fit a decent set of 17 inch wheels, with decent tyres Slicks or the before mentioned Bridgestone supersofts.

Get your suspension setup correctly, front and rear, no point doing one and not the other. Not sure about the RGV, but the rear shock on the RG bucket I built was hopelessly soft, we made a spacer to stiffen it up a bit.

These two points should be the key issues in starting to buils a bucket. Worry about engines and speed later.
