Rear Shocks

I recently took a lady friend for a ride on the bike. We bottomed out on every little bump. Neither she or I are unusually large. But even before that I noticed that the bike was very spong feeling in the back, and I would almost bottom out on even the smallest bumps while riding alone. I pondered the situation, then remembered the shocks are air assisted. Went to a garage, and tried to get a reading of air pressure in the shocks, but couldn't because the air would be let out of the shock as soon as I touched the air nozzel to the intake of the shock. Anyway, to get to my point, I was able to put air into the shocks. Now my question, how much pressure should I be running in them for a safe and smooth ride?

Re: Rear Shocks

Good rule of thumb seems to be..
Rear shock air pressure (10% of total load weight)

Talking Re: Rear Shocks

YIKES, that means that I'll have to ask the weight of every woman I take for a ride on the bike. Guess I getter get some cheek protection, might get slapped a few times Thanks for the advise

Re: Rear Shocks

Just ask AFTER you put the full face hemet on. Of course that leaves other areas vulnerable. Best to do a silent estimate and I'm sure if you come close the ride will be a bit more comfortable.

Re: Rear Shocks

I found a special low volume hand pump at a bicycle store. The mountain bikes use air springs. It cost $30, has a built in gauge and when I disconnect it from the shock, I lose hardly any air. The chamber for the air spring is pretty small. Everytime I checked the pressure with a regular air gauge, I lost about 5 pounds of pressure. You shouldn't try and fill them with an air hose at a garage. The maximum pressure is 43 pounds and overfilling can blow a seal. If you have a compressor at home, and can adjust the pressure to the 5 to 40 pound range with the built in regulator, you can use that to fill the shocks.

Re: Rear Shocks

Re: Rear Shocks

There is no "stock" air pressure for the rear shocks.
The general guide is 1 lb of air per 10 lbs of rider/luggage weight.

So if you weigh 200 lbs you would put 20 lbs of air in each shock.

Do NOT use a regular air compressor to do this. Either get the special hand pump, or, get an air tank, fill it/bleed it to the pressure you need (e.g. 20 lbs) and give each shock a quick shot with it. The shocks only take a very little bit of air compared to what is in the compresor tank, so they will be even enough in pressure.

Thanks, RB. I just bought a 2001 VN750 Monday, and was wondering why I was getting jolted so hard with every bump in the road after all the magazines complained about the "mushy" suspension.

The shocks are loaded with SEVENTY PSI.

I'm 215 pounds, so looks like I'll set 'em at 23-25 PSI to account for my gear.

Dang, I should check my shocks. Evertime I hit even a moderate bump, I'm sure that my kidneys move about 5 inches.

I have about 5 psi and the shock set to 4. With the wife on the back (we total about 275) the ride is pretty good.
