Well i finely got my Hagon shock today. Ordered on the end of Jan. so it took aw ail. Good news is the shock looks great and I like the red spring. Bad News is Hagon did not give me the heavy spring and did not do the stiffer valve up grade I asked for.. Hagon said that it would be to stiff for single rider. Guess I have to go with there choice and see what happens. Hagon did only charge me $569 for shock with remount damping:03biker:

I am a solo rider of 168 lbs. Hagon specified for me a 1000# spring which is apparently the stock spring with their ST1300 shock. I have been very happy with it for about 4000 miles. I had to stiffen the damping quite alot from the out-of-the box settings. The thread pitch for the preload is so fine I made a Dymo label with 20 increments so I could keep track of rear sag settings.

I'm at a loss at Hagon did not build the shock the way I ordered it. I weigh 200 lbs plus gear, wife 135plus gear. I asked for the heavy spring when I but order in with Dave Quinn. I'm a little ticked off that I can't get what i want when I made the deal with Dave. I'm thing about sending the shock back to them before I go too the trouble of butting it on the bike and finding the spring to soft. Can't send it back if you install it on bike. I'll call Dave to see what he thinks.
 
Half my riding is two up. That's what I wounted the heavey spring , plus I tend to ride the ST hard solo. Why buy a new shock and get the same soft ride as stock.

If they didn't provide you with what you wanted, what you paid for, then you should absolutely send it back, and they should pay the freight. You can contact Hagon directly via e-mail and check out what you where told.

E-Mail: sales@hagon-shocks.co.uk

Dave has proven to be a straight up guy, but everyone makes mistakes, I just hope that he wouldn't cover one up by trying to talk you into keeping something you don't want.

OK I talked to Dave Quinn today to what to do with the shock. After a short call to Dave He said to send back the shock and he was going to order me the shock with the 200KG spring right away and not weight for me to mail him the stock one.:D :03biker: .ED
Spring rate ---------- Rider LBS ---------- PIllion/luggage
1000 ------------ 176 ---------- 154
1118.4----------- 231 ----------- 197
1258 ------------- 308 ---------- 264
1398 ------------- 439 ---------- 418

I just received my Hagon. I told them to build it for my 2up and loaded weight of 440lbs.

The sales guy said I would be getting the 1118lb spring. The spring is labeled 225kg, but there is no pound rating anywhere.

Now it sounds like I may have a spring that is too heavy. Do you understand this enough to give me guidance before calling Dave and asking?

Thanks, Robert
 
What are the complete units for displacement? Spring rates are usually specified by units force/units displacement. if it's lb/in and Kg/cm one could do the conversion to the same units and compare. You need to know the displacement units in each case though.
 
When I wanted to know the pound equivalent of the spring as delivered on mine Dave Q. had to query Hagon UK for the formula. It wasn't as easy as converting kilos/mm to pound/inches. Still, I had the answer the next day.
 
I'm trying to figure out the math on this

Math isn't my strong point so correct me if I'm wrong

225kg/cm= 12375 lbs/in

Hi Robert if you look at my last post I listed the spring weight for each rider @ pillion/ luggage. What I left out is the KG/cm2 weights for each spring.
180/1006
200/1118.4
225/1258
250/1398
If you got the 225K/cm spring is 1258lbs/2
Hope the make it easy for you .ED:03biker:
 
A kilogram = 2.2 lbs.

One inch = 25.39 mm.

Plug and chug.

225 kg/cm = 22.5 kg/mm x 2.2 #/kg x 25.39 mm/1 inch = 1257 #/in.

Most of us on this website in the 225-260 # weight range are running 1300# springs. I think you'll be OK.

Hyperco springs can be purchased from hrpworld.com for $64.95 each if you decide to bump up on the spring rate.

It's a heavy duty spring.
UPRATES M51085
REMOTE PRELOAD ADJUSTER

But I can't get the sag (w/ me on bike, not gear) to less than 1-7/8 inches, even at full pre-load (not the recommended 1.5 inches).

In fact, changing pre-load makes little difference.
No pre-load =~ 2-1/8 inches
Max pre-load =~ 1-7/8 inches.

Should I be concerned by this?

If correct preload is important to you then yes I would be concerned. I set my preload to 1 3/16" using about 35% of the preload's travel. A dumb question - are you sure that the preload adjuster moves across 38 mm of travel from fully unscrewed to fully in? It has very fine threads and will screw all the way up to the nut with the u-bolt around it. I found mine very sticky and hard to turn in all the way until I screwed it in and out a couple of times.

Correct me if I'm wrong guys, but isn't 1?" (approx 40 mm) the preferred dynamic sag on an ST1300?

There is a range of preferred sag depending on the bike, the rider, and the conditions the bike is ridden in. A figure of 25% to 33% of available suspension travel is often used to define sag. 25% of suspension travel is often used with sport bikes and smooth roads and street bikes and rougher roads at the other end or 33%. Where you like it could be anywhere in between. I use the 25% figure and this is about 30 mm or 1 3/16th"". 40mm (1.58") is about 33% of suspension travel.
 
Hi, I;m wating for my shock to come sack.with the 1100lbs spring.If that works out to b e to soft I;ll have to get the next heavey spring. What's Dave charging you for the spring? Thanks Ed:03biker:
 
I know Dave was not happy with me either, I ordered my shock before the price increase. It took 3 e-mails and two phone calls to get him to reorder the shock the way I wanted it made. We had a long talk about how most ST"ers have gone with the 1300lbs spring. He just couldn't believe that Hagon would be that far off with there set-up. Ed

I don't have my shop manual handy - it's at my other house. What is the total travel of the rear suspension per Honda? Doing some reverse math, if 30 mm = 25% of shock travel, and 40 mm = 33% of shock travel, then total travel should be 120 mm (4 3/4"). Did my college education serve me well?

I agree, dynamic sag should be on the order of 1/4 - 1/3 of total shock travel.

BTW, 1?" static sag would be way too soft a spring IMO.
 
You can always add some preload to compensate for sag when you add weight, but you cannot add length to your setup once installed.

The higher you run your rear end, the more you are going to push your front end and that's not something you want to do with a near 800 lbs bike. If you are riding 2up you really don't want to run out of rebound, it is an undesirable result.

I'm really wondering if the spring rates I am seeing thrown around are truly needed, are you guys seriously bottoming out a 1000 lbs spring?
