Rear tyres:180 or 190? What's your preference?

[MSTRS:Me]

I just put some 190/50/17. and 170/20/17 metzler roadtec z4s I think they are great best grip I have had on the bike so far. I had Bridgestone before that which were good but splipped a bit.

Do you mean Z6? Or Mez4? Z6 superceded the Mez4 and is a better tyre all round. There is also a new generation Z6...http://www.metzelermoto.com/web/prod...6/default.page

My 86 Gsxr1100 currently has a 160/60 on the back , I'm wondering if thats as big as I can go? Anyone know for sure>

[Bladeslapper109]

Many shops are staffed by morons.

I start with the tyre size the manufacturer specs for the bike, and take it from there.

Second that.

Cycle treads changed my chain and sprokets. I asked for standard sizes.
I get a rear sprocket 8 teeth more on the rear on a 250 2 cyclinder gsx.
those bike are pretty much at red line as it is at 120km/hr.

pilot powers are the best tyres i have ever had for sport bikes for road use. Commuting and twisties every day

I'm now on my second set of Metzeler M3s since i started this thread,( 120/70/17 front,and 180/55/17 rear ),and VERY pleased with them.

No problems in any conditions.

Hope to catch up for a ride with you sometime

Oh...I'll be easy to catch.Just ask Grizz.I ride like a nana.

But seriously,i'll be keen for that.I'm always looking for an excuse to go riding.(And meeting new,like minded people.)

I'll just have to work it in with my shiftwork,and the shite weather around here.

What prices do you pay for M3's? Are they duel compound?
Have you ever had Pilot powers?

I dont think its possible to ride a blade like a nana is it

$610
was the cheapest i could find around here.(that's not fitted.)
No they're not a duel compound,but i can get about 15000kms out of a front.
Nah...I haven't had the PP's.

After 20+ years of not riding,then doing 4500kms on an old school bike,and then stepping up to the blade,lets just say i'm a bit tentative.

I got Michelin's PP2CT on my 05 blade. It is the duel compound tyres and turns into bends as quick as Conti tyres. Done 4500km on them front still has 3mm and rear 2mm to go.

Go and see Cycletreads and see if they will do a deal for you. Expect to pay more for the 190 size rear than the 180.

Agreed, with any 1000cc bike the amount of power it generates dont think it is built for nana riding.

Yea i got them fitted for $600 PP2's

my power is shit i reckon. If im cruzing at 100km/hr im only ever in 4th geear but i know my rear is the standard 40 tooth. Unsure of front but surely must bbe geared to high.

4th 100km/hr about 4600revs roughly
What gear rev's you getting?

it sounds like you're stock geared (16/40)
Im on my 2nd set of m3's, they're allmost shagged at just under 4000km.

[naphazoline]

Those revs sound about right for stock gearing to me.

4000rpm in top is 100km for me,but the 06/07 is a little different to the 04/05 models.

You contradict yourself, and so does all the data from every tyre manufacturer I could mention.
Consider this - if it takes more effort to turn in, is that better ? and how does this all relate to the mid turn radius a bike will hold for a given lean angle ?
Simple truth is this - if it takes a lot more effort to initiate a turn, then the bike is just not steering as well - simple.
I stand by what I said - the science behind it is correct.

How the hell do you figure that out??????
If you apply no effort the bike goes straight. if you apply x amount of effort you get x turning. If the bike needs x effort for less lean that's because its turning more.
The bigger tyre sits the bike onto the edge of the front tyre more, hence faster (not easier) turn-in. It's simple.

[DEATH_INC.]

The 190 made the turn in more tricky,

Can you clarify what you mean by 'tricky'?

[Tony.OK]

Can you clarify what you mean by 'tricky'?

Having a 190 on a 5.5 rim squashes the tyre into a taller profile, that can make the turn in aggresive, because the tyre is pointier you basically fall into the turn, but once your over, there is greater grip through a larger contact patch.
