I have a 2001 1200 custom has a rough ride in the reear end was looking about putting new shocks on heard of tryin road king air shocks? was wondering if anyone else has tried this and if it was just striaght forward change? thanks for help..

 

Don't bother - go look @ Progressive or Ohlins...

 

I put on Progressive 440. Now the 440 are for sale. I'm using the RKs with zero psi.
I'm only 155 and think I'm just to light for the 440s.
Yes it was a simple easy swap to the RKs. They're softer than the 440s, and I can put air in when two up. In spite of trying to sell the 440s I recommend the RKs.

 

on your RK's what year were they designed for? is there a specific years I have to look for? When i am two up live on kinda rough road i am bottoming out the stock ones so was told RK's were best route i am new to owning a bike so this is all new to me?

 

My stock shocks were bottoming out too. The progressives 440, ended that, but the ride was still rough.
On the RK, I got the 13" which was the same height as the original shock, I don't know about the year.
I weigh about 155 so I run 0 psi. It's a softer ride than the 440s.

 

I replaced the stock 11.75" shocks with Progressive 13.5" 440 standards. I weigh 205 and the 440s are perfect. I installed Progressive fork springs and use 7w BelRay fork oil and the front and rear work in perfect harmony. I used the spacers in the forks at their full length.

 

i weigh about 200 ride two up about 50% time so want something adjustable sounding like the RK's best option. i been reading about the air valve needed for these shocks anyone know where to get that? and also seeing where some people been using streetglide shocks because does not change ride heighth? And what size washers did you need IBGary?

 

I used about spacers about 1/4".
The RK shocks came with the air valve. That's the only part I don't like. It's just easy to adjust the preload on the 440s, I just couldn't change it enough.

IBGARY so ur shocks came with the valve not a plug? seen where some people where haveing trouble finding the valve itself?
