Recommended pressure for 2-up?

I'm looking for ballpark.
Also, do you pump up both, or just the rear?

The swingarm sticker has the numbers. If nobody's answered by the time I get home, I'll go look at mine and tell you.

Yeah, that's long gone....

By weight I interpolated between the two specified weights/pressures to get these lines front and rear which I use for guidance. The two were 198 lbs - 33F/36R and 418lbs 36F/42R.

With the total weight of passengers ranging from 198 to 418?

Total weight of everything on the bike - you, a passenger, luggage, gear, etc

Got it! Haven't hear the word "interpolate" since thermodynamics.... don't miss it a bit!

I guess technically I both interpolated between 198 and 418 and then extrapolated down from 198 to 125 b/c somebody had asked. I wish I could say that thermo was a long distant memory but it's not for me.

Great graph. Thanks for that, repped.
I thought it would have jumped more than that. I went for a ride last night with my GF and aired up to 38/40. My usual is 35/37, I could have left it at that.

Sticker says 36 front, 42 rear.

They say 36/38 is the optimal pressure for the street. For 2up, bump them up 4 psi or so.
