Running 'em on a ZRX1200, Recomendations on "street" pressures?
Thx.

-Rocky-
 
I like 38 front 36 rear for commuting and 34 front 30 rear for sport riding. But that's me try it and make personal adjustments.
 
38psi rear/36psi front

edit: the PP need that high pressure even for sport riding. Thats just my experience.
 
Pilot Powers are pretty soft and should be run at quite high pressures like 36ish.
 
ZRX1200, what do those bad boys weigh?

And the internet says something like 514 pounds. Not sure if that's wet or dry weight.

Not a touring porker but a little heavy-ish of a bike.

For solo rides tire pressures in the 34-37psi range are my guess.

If you load up with a passenger maybe the 36-39psi range.
 
what would you guys run for 2CTs on a (naked) 929, rider 195 + gear?
 
wow, that high? a friend at the shop I had put them on (he instructs at trackdays) suggested 32ish.


also... suggestions for pressure at a trackday? streets of willow on nov9...
 
:wtf I'm seeing all these astronomically high pressures and always higher in the back...wow! I started with 33 front 32 rear and worked my way down to 32 front 29 rear. That's on the street, 90% twisties and on a sportbike weighing 420ish wet. YMMV

I've never heard of people running higher in the back than in the front though, unless you go by the swingarm settings. Good luck with that, let me know what the moons looking like when you highside there and back :laughing

Even on a literbike (954, also about 430wet) I'd run 33 front 30 rear.

I always got 3000-4000 miles out of 'em (depending on the pace and the surface ridden on) with the rear done and the front with anywhere from 25-50% remaining.

On a much heavier bike you could go up a few pounds, like 35 front 32 rear.
 
I think the reason to run the rear higher is to get better mileage out of it. I know on my KTM it RAPED rear tires like that was it's purpose in life, but higher pressures helped a bit.
 
I got my first set oh Pilot Powers on the R1 back in 06'.
I normally run sportbike tires at 30psi front/31psi rear for spirited riding and 34/36 for commuting.
At the time the PP's were THE tire and everybody were hyping them up.
With 30/31 pressure I was imediately unimpressed. I called Alex Florea [AFM Michelin provider] and he recomended 36/38. If I remember corectly it had something to do with the higher silica compound.
They imediately felt better and since 06' I've had at least 4sets of Pilot Powers without any problems even ridden in a spirited manner.
I would at least recomend trying how the bike feels with PP set at 36/38 psi before dismising it.

This does make sense, but I seem to always weigh performance and feedback over longevity, and again I still got 3k at the worst (one set) to 4k (most sets, and I've ran probably 8-10 sets on 4 different bikes with those tires).

When I firt got a set on my CBR 600 F4 back in the day, I ran 34 front 38 rear and it did feel good. Once the pace started coming up the rear started letting go earlier than necessary and this problem was greatly reduced by lowering the rear until I eventually got to a sweet spot of 30 (and I'm not talking track right now, where I also ran PP2CTs for a bit, but at 31front/30rear or a pound less each).

The front does feel good at 34 but depending on the bike setup and riding style will feel just as precise at 33 or 32 however will offer a bit more grip and feedback before letting go.

If I were to strictly ride the concrete jungle on a heavier bike (I commuted on a 5th gen VFR last year on PP2CTs too) I'd run 34 front and 34 rear...just bump that rear down to 32 for the twisties :ride
 
Recommendations on pressure for Duc 1098 120/70-17, 190/55-17? Street and/or track.
 
I am pretty sure factory recommendations are far higher than most on here seem to run.

I run as high as 42 rear 38 front. Never had even an inkling of a problem with grip at all. Can't imagine running below 32 in any situation?

Usually run 37F 39R for the street. Have tried as low as 30F which just feels weird and squirmy to me. My bike is pretty heavy though.

But, I know guys that swear that they have to use cut slicks on the street for their mad skilz yo, so what do I know? Of course, they never seem to go any faster than I do?
 
Why exactly do you run less pressure in the rear? Isn't it the front end you want more grip on?

I don't know about you but I'm a lot harder on my rear tire and require a lot more traction from it, hence I wear out 2 rears for every front on the street and 3 rears for every front on the track. All the recommended pressures for hypersport/dot race/slick tires I've seen are lower in the rear than in the front, both cold and hot psi.

The front seems to be great between 32 and 34. Anything more and you're limiting your grip levels, anything less you're limiting your precision and nimbleness. The rear's good from 30-34. While I agree that 36 or 38 might still feel good, traction level and feedback are going to be diminished.

There are some for whom that traction is burning a hole in their pocket. Others, who figure they will negotiate with the corner, and see what kind of deal they can get...
 
Thanks. (even though I'm more confused now than ever!) I'll start med-high and work down from there.......

I ran 36/36 at the track with my SV, it was perfect (these are regular PP's tho).
