919 tire pressure?

OK i know this is like asking what oil is best... but what pressure you guys run front and rear in your 919?

Depends on the tire brand & model.

Generally speaking though the pressures listed on your swingarm & sidewall of the tire are MAXIMUM pressures designed for carrying the maximum load rating of the tire. If you are not carrying around the maximum load rating then reasonably lower tire pressures will give you a more compliant ride & better overall grip.

When I ran the Z6's, I kept at the "recommended" (by the bike shop) pressures - 36F & 42R. Never got to like those tyres, although I don't know if I was running them to hard...

Since I have switched to the Pilot Road 2's, I run them pretty low, about 33/34F & 38R and love it! Havn't had a "moment" with them so far. They are great in the wet and dry.

LDH is muted in his reply.
There isn't a tire out there that displays its best performance at the OEM suggested pressures.
Legal paranoia makes them state the pressure that provides the max load rating of the tire, regardless of what bike it happens to be on, let alone details how heavy the payload is.
42 in a rear in cold weather and on a hard sidewall tire is like being on a corduroy road.
OK, enough of my ranting.
I'm running Michelin 2CTs on my 919, and had Michelin Roads on before.
For solo road riding 31/32 in the front, 35 in the back. I weigh 170 # before gear.
When I have my wife on the back, I bump up to 33 front 37.5 to 39 in the rear.
If we were to tour, with lots of day long straight up miles on hot pavement, rear at 40.

Previous owner put on a set of Shinko Advance 005's

180/55 in the rear

120/70 in the front

I think i got em around 32 psi front and 36ish in the rear.

I weigh in at 165 without gear... might drop em down to 30 / 34... always thought the rear could be dropped some.

Thats about what I run mine. I'm about 125 w/o gear. The recommended tire pressures are too hard for me.

I'm 185 before gear and I run 32 Front and 38 rear. That's on a set of Michelin Pilot Power 2.

I have about 5,000 miles on the rear and 6,500 on the front and they appear to be just around half worn.

Press Any Key To Continue.

Sike, it's the words that begin with vowels that really light up the banter.
Air
Oil
Octane
And I must admit, I fall victim to it.
Just can't resist !
