I was wondering what would be the advantages of running a soft rear (diablo supercoras 0) and diablo supercorsa front 1 or would this effect the bikes handling to much.I have always in the past run the same compond any advice would be appreicated cheers john

[scooby]

general rule of thumb is not to have the rear softer than the front as it can end up pushing out the front due to less grip.

I always run a soft front and a meduim rear if I buy sticky tyres.

If I'm buying normal road Tyres then I just have matching

At the end of last season a lot of SC1 fronts/SC0 rears came onto Ebay - I asked the guy about this - basically said - "interesting combo is it for qualifying?" the reply was - "No for the race - maximum rear grip means less risk of highside"

When you look at it that way it makes sense, also they changed the rears every race.

yep i know few people do it,but is something i was told a while ago and has always stuck with me.we had a bit of a chat about it on SBF last yr as 1 of my m8's put this type of combo on after asking me my opinion (which was as per my 1st post) but thought he'd try it anyway.3rd session at oulton front washed out,flipping the bike over the barrier.not neccessarily because of the tyres,but he doesn't use that combo anymore

The softer the back the more grip you will have and the harder it will bite if you loose that grip and regain it (highside), I like my bike tyre to have less grip (harder compound) as I get more miles out of it and easier to get the back to spin up if want it too.  one of the tyres will loose grip 1st and I want it to be the back.

Thanks lads but now my head is well f**ked up with compounds i have the same thoughts like scooby but now what taqman says makes sense also cheers lads

John is this for track or road use?

I am not track minded but I watched twist of the wrist 2 yesterday and it is very interesting in making you understand the technical side of things, the bike is designed to have same amount of weight on the front and back wheel and on mid corner you should be accelerating at 0.1-0.3gs there for the weight transfer is going to be roughly 55/45.

Like I said before I don't do track.

[scooby]

how are you going to know what g's your accelerating at  without data logging ?

[johnmoz]

alright nutz you doing this on purpose to confuse me more does 55/45 mean you would have a softer tyre on the rear then 

[scooby]

just ignore that bit 

[Nutz]

how are you going to know what g's your accelerating at  without data logging ?

well 0g would mean you are not accelerating or decelerating so after the braking and the flick in you should be on the gas into mid corner with a tiny bit of acceleration (0.1g - 0.3g)  I suggest you get a copy of twist of the wrist 2 it makes some very informative watching...............even if you think you know it all...................now my aim for this year is powerslides

alright nutz you doing this on purpose to confuse me more does 55/45 mean you would have a softer tyre on the rear then 

It means in mid corner you have a tad more weight on the back than the front because of the tad bit of acceleration.  A bike that is not accelerating or decelerating will have roughly 50/50 weight distribution.

In my eyes more weight on a particular wheel means more grip it will have which is why if you want the back to come up under heavy braking (endo) you shift your weight to the front, if you want better braking you shift your weight to the rear and use both brakes, if you want to brake like a prat and risk coming off under hard braking you shift your weight to the rear and use the front brakes only.

funnily enough i'm aware of what G's are and read the books,the point i was maiking was who the hell can tell,whilst riding a bike out of a corner what g's they are puilling..   it also depends a lot on the type of corner,a fast sweeper is taken quite different to a tight hairpin.

theres a difference between reading what a book says,understanding what it says and putting the information into practice.

[Nutz]

I totally agree with you mate, but surley you can tell if your accelerating, decelerating or holding the same speed.....................if not get a loader exhaust  .

End of a day a corner is a corner, it involves slowing a mid and a exit, it just how you take them that is different.
