Definitely just idle musing about what may be possible. No plans but may go and have a chat with the guys at PDQ or Nitron if I am in the area.

Ah ok. Most of the time I reckon the forks aint bad now, but could improve. Im still curious about the Hyperpro option. Seems weird that Wilbers go with 7.5 oil but Hyperpro with 15, thats quite a difference.

What do you not like about Wilbers' fork springs?
Harshness over potholes or wallowing during riding maneuvers (or both)?

Well,
I had both and kept the hyperpro. I just could not get a comfortable setting for the wilbers. (Will put the up for sale when I have some more time).
They were fine on pristine roads, but killed my neck on degraded roads, of which Belgium unfortunately has quite a lot.  Potholes were horrible.
Hyperpro's dive too much, because they seem progressive (too soft in the beginning) over a longer part of the spring.
But I'd buy them again if a change is needed. I also had the hyperpro rear spring installed, but I don't really feel a lot of difference with OEM.
I'm no specialist, so I had my dealer set up both sets. He said the Wilbers would perform well on a track, but are way too hard for Belgian roads.
Hyperpro are a bit more compliant, but probably too soft for the extreme curve thrill seekers among you. Me, I just enjoy spirited driving on the highway and b-roads, but I'm not a twisties addict, so I don't need the ultra setup, nor can my neck handle that.

Ah, well after R3morf3r's  comments above I might not bother. Yes the Wilbers do seem a little harsh over some surfaces, but actually I'll put up with that then cos I definately dont want any more dive

Hi Timbox,

it's a very personal thing, this difference.
I can set up the Hyperpro's so hard it gets painful too. I just have more headroom for softer suspension with them.
At the price they are, trying them out isn't going to ruin you and YMMV, as I am dealing with a sensitive neck.
That's also the reason I'm still looking for the perfect screen. It's either wind noise or turbulence, to solve both is a bit of an issue, when you don't want to move your handlebars more to the front and lower (to tuck in behind the screen), but that is off topic here.

All the Best,

RM

Ok, I finally ordered a Wilbers too, black with red spring to made it looks like the original one.

Hope it'll be correctly sprung for a 50-50 ride with pillion.

Be interesting to compare spring weights etc, think I ordered mine a bit on the heavy side for pure solo use, 90% of the time though Ive got topbox etc and its fine for that

I've contacted with Wilbers myself - I am also preparing for ordering Wilbur. Thought that some info below can be useful.

My first e-mail to Wilbers:
"...
First, some info about my bike and myself, to clarify:
My bike: Triumph Tiger Sport 2013
My weight: 110kgs + 7,5kgs of full gear
My riding preference: 50% of solo riding, 50% of riding with top pannier (fully packed pannier weight 20kgs), no riding with pillion.

I am interested in 640 or 641 shock and perhaps front springs?

Things I would like to ask:
1. What material do you use as external shock tube - is it made of aluminium or steel?
2. What is the diameter of shock shaft?
3. What are the differences between the shocks made for rider weight? Is it only the spring, or do you also change the viscosity of oil or shim stacks too?
4. What spring rate can be fitted to my potential shock? can you tell exactly by parameters that I have mentioned above?
5. Due to some budget that I have and would like to put to my bike suspension...I am thinking between 640 ROAD series shock and front springs or just 641 shock for now.. what do you rhink would be best thing to buy? Do you have any feedback from any customers that bought only the rear shock and complained a lot about the front suspension later?
6. What will be the difference between Promoto and Wilbers front springs? Price listed in Wilbers-shop is for a set of 2 springs?
7. Can you also tell what type of spring will fit me and my riding prefference? or is there only one type of front springs rate?
8. 640 ROAD shock is so-called emulsion shock? or does it have IFP-internal floating piston?
..."

Their answer:
"...
1. What material do you use as external shock tube - is it made of aluminium or steel?
The external shock tube, you mean the compression tank? In any case both cylinders are made of steel!

2. What is the diameter of shock shaft?
The diameter is 14 mm!

3. What are the differences between the shocks made for rider weight? Is it only the spring, or do you also change the viscosity of oil or shim stacks too?
The shim stack is picked in accordance to the weight and rider data however the oil viscosity stays the same!

4. What spring rate can be fitted to my potential shock? can you tell exactly by parameters that I have mentioned above?
For your weight we would pick a spring with 180 N/mm spring rate!

5. Due to some budget that I have and would like to put to my bike suspension...I am thinking between 640 ROAD series shock and front springs or just 641 shock for now.. what do you rhink would be best thing to buy? Do you have any feedback from any customers that bought only the rear shock and complained a lot about the front suspension later?
If you have to decide between the shock with compression tank, or the remote hydraulic preload adjuster (is an add-on at 199) I would in most cases recommend the hydraulic preload adjuster! The reason is that you can hardly reach the spring preload when the shock absorber is installed and it is very comfortable and easy to adjust the spring preload from the outside to match additional loads. However as you are mostly riding solo, you could do without the hydraulic although it is nice to increase the preload when you put the top pannier with luggage on the bike! The 641 version offers more adjustability but we can get a solid basic setup with the normal 640 shock, too!

6. What will be the difference between Promoto and Wilbers front springs? Price listed in Wilbers-shop is for a set of 2 springs?
The Wilbers Zero Friction springs are fine finished in a ceramic bath and therefore have less friction and cause less abrasion in the fork oil than the Promoto springs! Concerning measurements and spring rates, both springs are the same!

7. Can you also tell what type of spring will fit me and my riding prefference? or is there only one type of front springs rate?
Front springs must match the motorcycle, not the rider therefore both springs will work with you!

8. 640 ROAD shock is so-called emulsion shock? or does it have IFP-internal floating piston?
It varies from model to model but for your motorcycle the 640 shock absorber has NO floating piston!

I have an Ohlins with a remote preload adjuster. When choosing mine, I had many recommendations. I settled on a 160 N/mm spring at the rear. With ZERO preload, single rider 105kg, no luggage, I meet or beat the sag specs. The ride is firm and it was strange to have the bike stay almost level when coming off the center stand. On the road, it's perfect. I mention this because I'd be careful in choosing a 180 N/mm spring for myself as it would likely be too firm. I did have a 130 N/mm fitted for a while and it actually performed fine. I had to make a choice when I sold a spare shock a while back so kept the 160 N/mm. I cannot imagine going any firmer so if you do go with that rate (180 N/mm), let us know how it feels and performs.
When folks ask me how I am, I reply "I'm here". Seems odd until you consider the alternative...

So, as you can guess being the OP of this thread I have a Wilbers, and mine came with a 160Nm spring with 10mm of factory preload. that was for me at 85Kg with 30Kg of luggage 50% of the time. To be honest with just me and no luggage its a bit firm, OK, so at 110Kg you are a bit heavier than me, but even with all my luggage I rarely have to add any more preload.  180Nm does sound a bit strong to me also
