Sport Demon life expectancy?

[marine0089]

Hey guys.

Am still very (VERY) new to the world of bikes and am trying to sus out all the aspects of the bike I have just bought.

My bike, a 2007 kawa EX250F is currently wrapped in sport demons. 100/90-16 front, 130/90-16 rear.

Am just wondering what the life expectancy of these should be on my 250?

Cheers.

[Hitcher]

How many km a year do you do and how long do you plan on keeping the 250?

[gatch]

If you arent out riding hard than easy 10,000km, I dont really know as I did alot of burnouts and plenty of spirited riding on poo suspension..

[Grumpy]

I put 15000kms on a set on a GS500 and they were still going strong when I sold the bike. That included a couple of track days as well. Treat em good and they'll last ages.

This is where I got the info I needed for tyre choice for the gpx. Using Kenda tyres, good in the wet and getting about 8000km from them front and rear.

Thanks for the help guys.

Seeing as I am currently only really riding around 20k a day the answer looks like quite a while :cool:

PS: HTFU, that link is golden. Cheers mate.

I got about 21000kms out of a front one. The rear didnt last very long.

I should have replaced the tyre at about 15000kms though.

I was riding a gsx750sf katana.

I dont know what kms they have done but i have them on my LC race bike, they grip well and are really good in the wet. About 12 race meetings (running 2 classes in 6 rounds) and 2 track days. I have replaced(with Demons) them and put them on my road LC. They have great street cred now lol. Manfeild was the last round and they were working hard , Still got heaps of life, The rear in in better condition than the front

Great tyres. Results obviously vary, but over 10,000 on the rear and up to double that on the front would be fairly normal. The only tyres that will offer similar grip peformance but longer life would be Bridgestone BT45s

[frogfeaturesFZR]

Have a set on my Fizzer, magic tyres, even better tnan the Avons I had previously. I've put 3000 k's on them and they look as good as new.

[zxr400#150]

hey, i used to run the sport deamons on my cbr250, i used to only get about 4,500km out of a set (if i was lucky) but i used push the shit out of them. have to admit they were good tyers all round, even in the wet

[boman]

7000km out of the rear on a 250 bandit. Ridden reasonably hard on a road I know well, and that is hard on tyres.

Keep an eye on your tyre pressures , the fastest way to wear your tyres out is to run them soft . 32 psi front and 36 psi rear on the little ex

Did about 8000k on my TDM with them. Felt secure but they chewed up really badly & the front scalloped in a spectacular way. The TDM has an 18in front which may have caused this.

32 front 36 rear.. crap I was told 40 on both for commuting or 36 for a more sporty ride. Should the rear always be a little more then the front?

Maybe I should let a little air out...

Someone told you wrong. I reckon 32f/36r would be a little too hard as well.

A piece of strings lenght is the measured area between the begining and the end of any supplied string, this also applies to rope.

Iwas lead to believe the preasure is better run softer rather than harder for tyre life-wear because the more preasure in the tyre the less contact patch on the ground.
I have demons on my race bike and the front tyre was wearing or chewing out real bad on the left side [south island tracks] and when i talked to my bike shop about it he suggested i drop the preasures down a bit and has made a big difference both the handleing an wear.

Or more precisely:
Exactly twice the lenght from the middle to one end.

Bugger glad ya said that John, i happen to have brand new BT45s on my steed and was sorta wondering the same bout how long they will last for

Let us know how they go. I've always considered SportDemons and BT45s to be the shizz for the smaller bikes ie <500cc. They will be great for grip (for you) but I think the extra weight they are carrying will decrease their life considerably. If twas me with a 750 like yours, I'd be going with Pilot 2ct.
