Thank you for that! I installed the Ohlins on the rear of my bike and while that made the improvement I was looking for it also seemed to expose the weakness in the front forks/shocks. I went through the same process with my Ducati 848. The front forks in the SD now seem to wobble a bit more now that the rear is more stable and kicked up a bit. I've got big travel in the front end and I've been adding more compression & rebound to settle the front. Same exact deal with the old Duc. Some Mupo's may be in my future.

Set the spring rate setting from 10.5 to 10. That seemed to be the sweet spot for my weight. Did a test ride after the change yesterday and was really happy. Have the compression and rebound set in middle of range and did not feel a need to change anything.

Hi. Probably in august im installing the TTX39 on the rear and a customized Öhlins FGK cartridge (30mm piston) to fit the stock bars, new caps with preload adjustment of course. There is not a lot to customize. I will give complete infos and parts necessary.

I'm 40 lbs more than you in gear, but have done the springs.

You only have 10mm of rider sag in the rear? It should be about 40mm from unloaded to you on it.
What is your front sag number?

These bikes have a lot of compression in the valving and are light on rebound.

Sooo, I recommend trying this as a starting point:
Rear preload 5mm with rider sag about 38-40mm
Front forks up in clamps 8mm.

Thought I would update this as I have gone from one end to the other and this is where I've arrived at:
Revised settings
Front Compression: 18 out - 20 out 10 out
Front Rebound: 7 out - 6 out 5 out
Rear Hi Comp: 1 turn out - .75 out 1.0 out
Rear low comp: 15 out - 20 out 10 out
Rear rebound: 5 out - 3 out 1 out
Tried to make it as plush as my adventure, but then it's not that type of bike 8-)
The rear rebound stack will need to be stiffened up a bit, everything else is in an acceptable range.
While the bike is a bit rough at slow trolling around it works wonderfully in its intended rate of hauling ass around on real roads.

Guys the trick with the 1290 suspension is the right spring weights. I got new springs front and rear and tickled the standard valving to suit and the results were excellent for the money spent. My rig handles as good as my mates Ohlins shod RSV4R I think it actually rides beta. The standard WP is petty good stuff out of the box.

What rates did you take and whats your weight?

I weigh 110kg with riding gear, I will ask the suspension shop what springs were used. I sent my forks and shock away to be done so I dont know exactly what springs were used. I tried to find the invoice but couldnt. You just dont need to spend shit loads of cash for fast road use.

Well 110kg i understand you have to change spring rates obviously, but the rear stock 170N/mm is enough for a 85kg guy, but the damping is too weak I reckon.

I'm going to go for the Öhlins TTX on the rear and on the front an adapted FGK cartridge from an S1000RR with 10N/mm instead of 9.5N/mm standard.

I don't spend that much as I can get good price :)

Compression is good but the rebound is weak in standard form. Thats why I tickled the standard dampening to handle the new spring rates. My personal opinion is the TTX is an overkill for street only use.

The factory shock is an awesome part. I had mine re-valved and with the correct spring for my weight. Only $300. The rear slick is smooth after a day at the track. I'm glad I didn't pay the $1458 for an ohlins shock. The only draw back is I wish the ohlins had ride height adjustability. This bike could defiantly use the rear higher. If there was an aftermarket shock available with it, I would defiantly upgrade.

An awesome part? Let's say it's a good shock absorber, but it is still a simple monotube damper, which has bladder instead of solid separating piston, which means it will lose all the pressure sooner or later and cavitate. The TTX technology is simply the best thing you can get, there is absolutely no risk of cavitation and the working pressures are way lower than in a monotube, which means less forces and less force gradient at the wheel, which means consistent performance.

You might say it has high speed compression adjuster and the ttx does not, ok, true, but whats the utility of this when the maximum speed seen at the damper is like 0.7 m/s (even lower in our bikes as there's no linkage), and it only makes people mess around with the adjuster.

I say I get good price, I won't pay 1500$ obviously, and what I will change without doubt is the front fork, to get some good fgk cartridge adapted.

The TTX is an overkill for the street. The Hypaflow is a good shock with ride height adjustment.

After investigating what is available for the 1290 my suspension tech has come up with the following options:
1. Front & rear gold valve upgrades and sprung to my weight. The rear is a relatively simple upgrade, but the shitty setup on the front requires a heap more work. His advice is coming from Shock Treatment, the RaceTech distributor. Cost around $1500 all up.
2. Front Cartridge kit from Andreani $1000. Ohlins TTX, KT-302 $2,050. Both sprung for my weight.
Does anyone out there have any expiriance with either of these options, cause after 20,000k I'm not happy with standard.

My mistake Hyperpro. I have your first option great for the street but with tickled standard valving as the rebound is week to handle heavier springs. Hyperpro make some nice shocks ride height and remote pre- load adjustment all made in Oz for around $1500. Also Elka is an option
I think they are venturing into road bikes real nice stuff out of Canada.

Why overkill? Just because you think so? TTX is the best you can get ^^ as easy as that.

I just finished dialing in a set of Andreani fork cartridges today. I like them a lot. Got them cheaper than your quote as well. PM sent.

I think it's a good one! How much did you pay? Is it a direct plug&play?
