Question Suspension ? Tyres ? Help pls..

I seem to notice that whenever i'm in a corner my rear end seems to feel like its sliding a bit.. i dunno if its the useless dunlop's or the suspension rebound or just my imagination.. If its not the tyres should i try to harden the suspension ? If i do harden it, how does it affect the ride ?

Re: Suspension ? Tyres ? Help pls..

is the sliding occuring entering the corner, mid corner, accelerating out of the corner? I noticed you've got an '08 so I'm not sure where you're at mileage wise (just to get a sense of what conditions your tires are in) but just hit us up with a few more details

Re: Suspension ? Tyres ? Help pls..

ok now are you on or off the gas at this point. What tire pressure were you running.

Reducing compression in the rear shock will usually add rear end traction, but if it is set to soft the bike will run wide coming out of turns and may bottom out over bumps making for a very nerouse ride. If the rebound is not stiff enough the bike will be very plush and will wallow around on corner entry. If there is to much compression the ride is harsh, rear traction will be reduced on out of corner accelleration, and will cause a tire to overheat ( also reducing traction ). If the rebound is too stiff the ride again will be harsh,the bike will understeer going wide out of corners, the bike will also jutter or jump over bumps mid turn.

If you are off the gas mid turn there is a lot of weight transfer to the front of the bike. If you have to much rebound damping the rear wheel may not follow the road very well and could cause the symptom. If you are on the gas mid turn it could be that there is either to much compression, or there is to little and the suspension is bottoming out.

If the tire pressure is to high the tire will be cold not getting hot enough for optimum traction. And depending on what lap times you are running and the type of tire, you may also be performing beyond the tires ability. We need more specific data to really establish the issue.

Not sure about the dunlops, and since you didn't actually mention which dunlops your on, this may not apply to you, but a lot of people describe the ride on pirelli's as "riding on marshmellows". It could be the same feeling with the dunlops.

thanks a lot for the very detailed explanation.. i do notice that my suspension's a bit soft, riding over humps and bumps.. so, if i do harden the suspension, should i harden the rebound as well ? am i right to say that hardening the suspension it will increase rear end traction ?

Re: Suspension ? Tyres ? Help pls..

There is no reason to change suspension at this point. Not sure about your riding expereince or your weight. But if the tires are new, are they scuffed in? How many miles are on them? What are your pressures at? What is the temp outside?

Im running a factory suspension on the track and im 220lbs, i have no problem with the tire sliding.

i've been riding for 4-5 yrs now.. the weather here's about 27-30 degrees celsius.. Like i said it's only went bout 600 miles. the presure's bout 320 kpi. the sliding isn't that obvious, but the sensation is there.. it could just be cold tires.. i'm about 147 lbs..

just messin with ya man

check your form. that could also be a big issue. and as silv said, also check that tire pressure. those two are EASY fixes. the suspension (spl i know!) can get complicated if you dont know exactly what you are doing.
