Picking the right tyre for the track.

[NoLogicOne]

I'm currently in the 1.55s-2.00

I'll try adjusting my pressure and see how it goes.

Thanks.

 

Since you are actually lapping faster, you really should adjust the pressure 1 PSI at a time, and take it easy until you think you are sure.

yup!... if u guys buy sport rider or cycle world or racer x u can cum across dis brand of tyre in their mags...its frm the US i guess cos u wont see their ads in the britons bike mags.

 

but dunno how reliable those rubbers are....is there any dealer dat brings dis brand to our shores..?

[kingpet47]

Come to think of it, I almost lost my front on T8. I think it is rider problem for my case as I downshift before that turn. I believed I upset the bike due to poor techniques. It was pretty scary. I used 30/30 on PowerRace Med/Soft. After that I was on Pirelli SC and Diablo SC which I really like, just like Metzeller RT.

 

For our skill levels, it is pretty hard to be sure what exactly went wrong.

 

as for my case i was bringing down my bike quite low n tucking in my knee to save my badly worn out slider n i jus lost the front...

 

to tink abt it.. i kinda regret.... coz wasnt able to join the 5 lap challenge...if not sure can get top 5.. hehe....

good luck to u - in UK the review for this tyre was very good.....i know alot of people who have crashed using these tyres....in pg

 

Ron Hasalm goes round Donington park faster than anyone else on trackday tyres, and he uses a standard CBR1000RR on BT-014s.

 

When the ZX14 first came out, the testors mentioned some guys managed to scrape the footpegs while going at around 250+. On BT-014s of course.

 

Many times I spin up the rear or lock up the front due to silly mistakes, but its easier to blame the tyre issn't it.

I was interested in these http://www.singaporebikes.com/forums/showpost.php?p=3302749&postcount=82

 

Post #82 of this thread. Motard riders like it very much for street and track days. But for races, I'm sure they dun use these tyres. The slicks you posted just launched probably, cuz not long ago, they only had the Stealth Soft compound to offer.

 

The price is very affordable, though it seems to had went up a little. You have to check if the profile is suitable, because it was noted to be "flatter" on the Stealth's rear, thus it was more ideal for drag racing

 

BTW, Maxxis is from Taiwan, Korea or USA?

Well, at least I've seen the Shinko 005 Advance selling in a bike shop. But that's the only pair and only model on the tyre racks.

 

Shinko is from Korea.

But it is Ron Hasalm you see (I think you meant Ron Haslam).....I'm sure Casey Stoner can go faster on Shinko shod 749R faster than anyone of us on a BT002 shod 999R in Sepang or PG

Adjusting higher or lower?

although It was stated about DC should be 34/36, i've got a lot of comments abt it. Like it was tested at different climates, or tested in a way that is not the same on how we ride it in Singapore. i'll try 33/33 the next time i head down.

[kingpet47]

to make it simpler.... they dun even cre if they thrashed those bikes..... they r given the licence to do it.. not like many of us here where our bike is our transport on weekdays n becomes a race bike on weekends n if u crashed on dat day.. there goes ur transportation for the rest of the week until its good to go....

 

i shall get a side bike... i tink i should..!

Read this thread from the 1st post....even Hart would also try it instead of hear say. At the end of the day, the rider is you, the feeling is yours to judge.

 

Of course, I mean increasing the pressures. But like many had said, take it 1 PSI at a time. Also do take note of the 5mm drop on your forks for the Diablo Corsa, which makes the handling better.

 

Last but not least, I hope you adjust your pressure at home before you ride in to PG, not reach there then adjust, especially right now you want to be sure what is inside your tyres, when you are testing new settings.

 

Have fun!!!

Guys, these Red Bull Rookies 125cc bikes are using Dunlop TT100?

[duckcula]

would like to know more about warming up the tyres...since there are quite a bit of talks on over-heating street tyres on track quickly etc.

 

How do you consider warming up the tyres or over heating them?

in simple terms, does riding 2-3 or up to 5 laps consider good warmup around PG? average pace...

 

What about riding 1 hr non stop average pace around PG, will that over heat the tyres in general? lets say eg using so call track days tyres - pilot 2CT or power race/Diablo Corsa...?

 

Non tyre expert at all here...thx!

I think it has all to do with feel. When my tyres warm up I can feel them 'bite' or grip if you will, harder during cornering.

 

You remember when cornering on wet roads, how the bike feels? Compare that to taking the same corner on dry roads. If the tyre is gripping well, the bike will feel more stable because the tyre doesn't slip that much.

 

Once it grips, it will grip so forget about the tyre and concentrate on your lines and technique instead. If you're newbie to tyres then just ride with street pressures. Once you start getting the feel of it then you can try playing around with suspension and tyre pressures to get a better feel in corners.

Could u explain more abt the 5mm drop? How do i take note?

I tried increasing 1 psi.. feels a little bouncy on my rear. i think.

Thanks mate!...think there are not hot and fast rules, is all about experiencing yourself, will let the butt talks to the bike, or maybe the other way

http://www.nesba.com/TrackTalk/bb/Forum1/HTML/000982.html This is where I got the info. You could measure the DC III before they mount the front tyre on, fully inflated to check if it is still 610mm Diameter, but then again, I hope that you would be using Race Dot rather, because of your sub 2min pace now.

 

Er, sorry I missed this out (I thought you would know), but actually, you might need to tweak the suspensions a little (1 click on rebound or compression +/-), which is not too confusing if you take note of what you click.

 

But if you find it too troublesome, I suggest it's time to throw everything behind and start fresh on Dot Race tyres

Hi guys,hope someone can help me ans this..how does the bridgestone 090 tyres perform on track?I am thinking of changing to a pair of michelins but i still have a lot of rubber left on my current 090 and it'd be a waste if i changed it.so before i head to track on my 090 i hope someone can tell me bout their own experience using these tyres on track.thanks and cheers.

Hey Ivan,

 

I had the same tyres on my spec 3 S**er Four. Suit the bike really well, I am guessing that you are riding a 400?

 

Anyway, they should be fine for the track but be wary:

 

These are tyres meant mainly for the street and are vulnerbale to overheating on the track due to the constant high temps... so feel for the "squidginess"... when it gets overheated. When you feel that, BACK OFF.

 

The michelins are being used by the Motard guys for track use and are probably much more resistant to overheating than your 090s.

 

The website stated that BT090 PRO is for racing use, but in this quote it says that it is mainly for the street?

http://www.motorcycle-karttires.com/RoadRacing.aspx

 

Can anyone please enlighten me on this field? Or are there BT090 tires (without the PRO thingy)?

Yes, BT-090 indeed is Dot Race tyre. The front tyre is BT-090 and the rear is BT-090 PRO. Get it?

 

Dun worry, Hart was already informed about this. He's very busy these few months.

Alright, thankies.

guys.... i use 30psi for my rear powerace n my tire is totally worn out until the right side thread is nearly lost........

hear from a number of ppl that powerrace worn out super fast then the other .......

Am using this on the DRZ400SM here. Actually wanted the 2CT version but did not get it because it they only had a 160 for the rear.

 

So I put on Michelin Pilot Power, front 120 and rear 150.

 

At the track last weekend, the temperature was about 10 degrees C. Needless to say, getting the tyre heated up to working temperature was a concern.

 

On the first lap I started pushing it abit hoping to generate some heat, expecting the tyres to slide around abit but was amazed to find that I was able to lean the bike over hard and the 'cold' tyres were actually gripping. Was running 20 psi on the front and 22psi on the rear.

 

Even after doing 12 laps on the 1.2km go kart track, the tyres just felt barely warm to touch.

 

The other guys who were running slicks were complaining that it was slippery on the track even after a few laps.

 

Lessons I learnt from that track session about the tyres were, Michelin Pilot Powers don't need much riding to warm up to grip... having said that... am sure they might behave like BT014s which heat up fast and lose all grip without warning.

 

The wear is minimal and smooth. The rub offs are very little and are very small pieces, coarse powdery texture.

I might wanna try Shinko 003 Stealth on the DRZ.

Hey Bro.. Havent heard your advise for a long long time. Hows life?

 

I tried 34/34 on my 2CT but i feel funny. Its turning in faster than normal. is the pressure too much or too little? Does squaring of tyre affect performance on the track?

 

Thanks =)

I generally use 33F 35R on sports tyres. You could use 32F 34R also, just try it out yourself. The thing above switching from different tyres to tyres is, the profile of different brands could be different, while some brands feel pretty similar (Metzeller and Pirelli feels the same to me). Michelin is rounder, and in fact I feel it's a struggle for me to wrestle the bike in. I much prefer the Pirelli and Metzeller feel though.

 

Another point to note is that the suspension height, which affects rake angle. Your bike could be set up perfectly for Michelins from factory, while mine may not. But at our kind of pace, these are not that important as long as we "lower" the forks until 1 inch or whatsoever.

 

Squared tyres definately have the "fall in" feeling as it transient from the flatter middle to the sharper sides. I would ride a few laps to get use to the feelings, but I will not be doing my "best" laps on squared tyres for sure.

 

Just sharing, dare not advise, for I might be wrong too.
