How much air do you run in the back?

Postby DougR » Mon Oct 03, 2011 3:15 pm



How much air to you put in the back shock when riding by yourself? And when riding with a passenger?

Just curious what the average seems to be.

I haven't yet bottomed with 13 lbs by myself, but hit bottom a few times riding double.

Thanks in advance

Doug

The full amount, 57 psi in the rear shocks at all times, solo, two up & solo with the trailer. I'm 6'1" and 93kg with all my gear on. The bike with some essential kit on & fully fuelled is 440Kg, (Don't believe what the handbook says). Front tyre pressure is 37psi and the rear is 40 - 41psi. Tyres are ME880's. The handling is not too bad for a big & heavy girl . I do crank it into the twisty's from time to time. Of course it dosen't handle like the 1800 but that is a different beast altogether.

Regards, Tony.

I would say that the amount of air in shock is greatly determined by one's height. Mine will easily go to 70psi with no trouble. Makes it easy to place on center stand, but my feet can not touch the ground.

Does additional air in the back make the ride harsher, or just raise the rear

It does firm it up. In the twistys it reduces the wallowing to a greater extent or even under normal riding when loaded and towing the trailer. It generally improves the handling for me. It is still very comfortable, and still softer than the 1800.

I would add or release air as needed and on how it feels to you. Everyone is going to run differant air psi. Try diff pressures as you ride till you find one you like when your 1 up and 2 up.


How many times do I have to tell ya,,, The right tool for the right job!
