New Progressive 465 RAP installed!

I had just rebuilt and re sprung the forks on my K7 Vee. My bike is very near 50k miles and the rear shock was severely lacking.
I ordered a Progressive 465 RAP from Rick and just finished installing it yesterday.
I wanted a shock that was less expensive than some of the options out there. I also do not ride in a manner that I felt that I need full adjustability. I tend to try and set up a bike for what it does the majority of the time and leave it.
The shock has a remote preload and rebound dampening adjustment (similar to the stock DL1000 setup).

One word of advice if you are going to remove your shock. Be prepared for it to potentially take longer than you expected. My last bike I did a shock swap in about 30 minutes while taking it slow.
I cannot speak for OEM or other center stands, but with the SW Motech center stand (love the stand BTW), the bracing for the center stand does not allow the lower shock mount to move out of the way for the shock to be removed. And the center stand mounting brackets get in the way so that you cannot unbolt the lower shock mount either.
So here I was with the shock unbolted, bike on the center stand, and my options were to remove the exhaust or the center stand to complete the job. I HATE messing with exhaust systems (especially a stock one on a bike with almost 50k on it). My next task was to figure out a way to take the center stand off when it is the only thing left to hold the bike up. I ended up using a floor jack and a piece of wood to lift under the passenger peg and placed a jack stand under the RH operator foot peg. Then I did the same on the left but had to put the jack under the side stand mount as not to damage the shifter linkage. I park my bike in a wheel chock and had tie downs from the bars to the tie down loops to help with not allowing the bike to fall over.
Once this was done it was a very quick change out to have the new shock installed.
I wanted to try it out so I installed everything including the center stand again. It was supposed to start snowing any moment. If it were nicer out and more patient I would have taken the center stand brackets to the grinder to take a little material off to allow access to the bolts that hold the lower shock mount to the frame.
I rode a couple miles (leaving shock settings as they arrived) and rode over manhole covers and other road conditions that would have been harsh with the old stock unit and hardly felt a thing!
I like faster corner speeds and try to ride very smoothly that uses smooth throttle and little to no braking into the corners. I think this shock is going to work very well and is less expensive than many aftermarket shocks. IMHO, many of the more expensive shocks are very expensive and most riders never really learn how to adjust them anyway.
I will definitely hold onto my stock shock for a spare for later when the new shock needs a freshening up.
A couple miles was enough to tell that this shock will make a big difference, but not enough to give very good feedback. Once I have had a couple good rides on it, I will post my thoughts.

subscribed as I am interested in your feedback. For some perspective, would you mind telling us how much "preload" is added to the shock due to driver seat "pressure"?

I think I have the SW motech center stand and Sasquatch and I changed the shock in the dirt at a camp ground.
He rebuilt mine at less than half the cost of the lovely unit you bought and put a nitrogen charge in it too.
To grease the bearings when i got home I had no problem getting the shock out on the center stand again.
Maybe I was in grave danger of a disaster and didn't appreciate the situation or it is easier than the trials you had?

This was a bit of a concern when I ordered this shock. I am 235lbs and there was not really any option for different spring rates. I was looking for something that would improve the ride and handling without breaking the bank and trusted Rick at Adventure Tech when he said that guys around 220lbs liked the shock.
I was able to take the bike out for about 40 miles yesterday. I still have yet to measure sag to set the preload so I just rode it the way it came in the box. It is definitely a huge improvement over my worn out stock unit! The shock has the same adjustments as the stock unit and after setting the preload for the correct sag, I will play with rebound settings to see what I like. Rebound settings will usually be different for sporty riding or cruising, so I will eventually play with different settings on sections of road back to back to see how much difference it makes.

My SW center stand has a brace across it that does not let the lower shock mount swing down and out of the way. I had already removed the bolts from the shock making it more difficult. Honestly, it probably would have been faster and safer to reattach the shock before trying to get the bike in the air. I am sure I could have spent less money having my stock shock re sprung and rebuilt but I hate the idea of a nice riding day and my bike unable to be ridden because of a missing part. I have purchased used shocks to send in before and had pretty good luck but I couldn't pass up a new shiny one.
One of my biggest faults is the lack of patience. I am impulsive and pay a price for it. In the end, I only spend what I am comfortable with. Sometimes you find a less expensive way to get the same results but I don't beat myself up over it.
It sounds like Sasquatch does really good work and actually turns it around quickly.

Update: I had my son help me with sag measurements. I put the panniers on and my too heavy tool pack and riding gear. A little research put a sag range from 40-56mm. With the preload maxed the sag is 72mm. I took the bike out for another 25 miles and it felt fantastic.
If I regularly had a passenger or was any heavier (235lb), I would want a stiffer spring.
For the most part, you only change your preload if you significantly are changing the load on the bike. I would prefer to have my sag correct closer to the beginning of the adjustment instead of at the max (16mm too much sag at max). With this said, I am still very happy with the purchase. I am hoping to lose some pound and if for some reason I find that I need a stiffer spring, I can always get one and keep the spring it came with tucked away for possible future use.
With a few hundred more dollars and some patience, you can send your stock unit out to be re built with the correct spring and tuned for your bike. I think this would probably be as good if not better than the Progressive unit.
I did not push to see if this shock could be ordered with a different spring rate. If it could, this it would be a great buy! I was told that guys up to about 220 have liked this shock and I believe it. I am 15lbs heavier than that so I was expecting to find what I have.
So it comes down to this. Knowing what I know, would I order it again?
For the price and convenience of not being without a bike, the answer is yes. I would do a bit more research into how difficult it would be to get a better match of spring rate installed before it being shipped to me, but if the answer was that it could not be ordered that way I would still get it.
If you understand how suspension works, paying up for fully adjustable suspension would be very nice. I do not get to ride often enough to justify it and impatient enough not to ship my stock shock off and wait for it.

Subscribed. Looking at suspension mods for my K2 Vee and it will be my first time upgrading suspension. Good to hear that you were happy with the progressive!

Update;
I have put almost 2k miles on the bike since adding the 465 RAP. It started bugging me that with the preload maxed, I still had about 20mm more sag than I wanted. I would prefer to have the sag correct with no additional preload from the remote adjuster so that the extra adjustment could really be used when the bike is loaded heavier.
I called Progressive Suspension to find out if I could order a stiffer spring rated spring. The answer was no but I was told that there is still adjustability on the shock body. The instructions that come with the shock tell you the minimum spring length you should have (188mm). Any shorter and you coil bind the spring. With this information, I assumed (since I did not make any preload adjustment on the shock body itself), that I would remove the shock and make a coarse adjustment on the body.
If you have read this from the beginning you know I had issues with the center stand. This time I removed the stand and modified the mounting brackets to allow the shock linkage to be removed with the stand in place.

Come to find out, the spring as shipped from Progressive is set with the spring already at its minimum length. I called Race Tech to see if they had a spring that would work and was told that they did not. They said that one could be ordered but they would not know what collars to use.
I found a local suspension guy that is having a custom spring made for me (about 3 week wait).

I was able to find a little more information about the 465 RAP though. The stock DL1000 spring is a 8.2kg spring rate and the 465 RAP is a 9.2kg rate.
With the 9.2kg rated spring, the rear suspension sag is 34mm too much (82mm) so I am trying to determine the spring rate I need. The Race Tech calculator is saying 15kg (235lb and I added another 25lb for the panniers and topbox).
I would be interested in hearing what spring rates others near my weight have used and liked.

Now I have paid another $20 for a spring swap (to be completed when the custom spring gets here) and another $150 for a custom spring. With the assumption that everything will be good after this I will answer the original question again.
Would I buy this shock again, knowing what I know?
The answer is no.
The shock is better than my 50k stock unit but the spring is right at a length of coil binding when the remote adjuster is at maximum and at 235lb, I was still about 20mm away from getting the right sag.
With the custom spring, I will have paid more than I would have to send my stock unit out to be re built, re valved and to have the correct spring on it. I am only a few hundred dollars from what it would have taken to order a shock with the correct spring to begin with.
If you ride solo and do not weigh more than 200lbs, I think this is a bargain and recommend the 465 RAP, but for heavier riders and for people that go 2 up often, I would not recommend it.

That's good info. Who would have though a $745 rear spring would not work well for riders over 200lbs? I only have a couple of thousand miles on my DMr suspension and I hate to admit this but I have yet to set the sag, but the ride is mucho better over stock. I will set the sag before tackling the eaastern portion of the TAT in late May.....that will be a true test of Jamie's work.

Update:
I was hoping the custom spring would be finished before going on a family vacation. Looks like I will have to wait until mid June to get my shock and re install it.
As soon as it gets installed, I will share any information I can.
