For me the BMW electronic suspension on my Gen 3 is the best I have used on the roads and for places like the Nurburgring but I found it wanting on short tracks where I just couldn't get the front to feel right. I've not done many miles on a 1299 Panigale with the fully active suspension but my feeling was that it wasn't as good as the BMW on the roads but it was much better on track because you could set it up how you wanted, even to the point of turning off the electronics altogether so it behaved like normal suspension. I rode a V4S Panigale recently on the road and that actually felt like race suspension, a bit too stiff for the road in sport mode, but I didn't get a chance to soften it up to see if it could match the BMWs road capabilities.
I've just bought a front Pot sensor to get proper control of my Gen 3 front end so I'm really hoping this will improve it as I dont want to shell out on race suspension just yet.

MCT supply/fit their own preloader which allows you to use the adjuster within a range. Rather than full wound off. Might need the spring replaced with flat finished items as opposed to the oem rough cut coil.

Does the pot sensor just give you the rebound adjustment?

It separates the compression and rebound stages of the front suspension allowing you to adjust both variables.

Thanks, this confused me as it says there's nothing in the right fork other than a spring normally:
https://www.ebay.co.uk/itm/BMW-S100...S-AND-REAR-SHOCK-WILBURS-UPGRADE/292729960137

Set of front DDC forks and rear shock to fit S1000rr 15-18
These have been modified by Wilburs / Triple Tuningmin Germany.
This alters the internal valving on the DDC leg, fits a standard rebound internal to the right hand leg which is normally just a spring. Oil levels and springs are changed. Fitted with 10 springs and setup for 90kg rider. It retains all the DDC benefits but adds more adjustability and fine tuning. Makes the forks react like a standard cartridge kit.
Also the stanchions have been DLC coated at extra cost. They cost ?1200 for the upgrade, ?250 for the DLC costing. This requires the original forks to be sent to Germany. You can by these and keep the originals or sell to recoup some money.
DDC shock.
Fitted with a 10 spring, it has high and low speed compression damping and a much larger gas reservoir. Still retains the DDC functionality with the added benefit of fine tuning.
Perfect working order, used for 2 rounds of the Scottish championship. Changing bikes for the rest of the year and no longer required.
The upgrade is ?1200 inc vat plus your original shock is used. This can be fitted and keep the originals

(sorry for the thread hijack guys)
 
It's correct - only the LHS fork is actively being adjusted by DDC. The RH Fork is passive. I don't know if there's 'nothing but a spring' and a preload adjuster in the RHS but it appears so. The Wilbers upgrade would have been a decent bit of kit - they used them in the IDM.

The OEM forks have 11-11.5nm in 1 leg and ~9.5nm in the other leg. There is slight variation but when the axle is in the force is the median between two i.e. 10.x
 
Theoretically then it should be about right for me now I have some dampening control with the front POT. I'm 83kg and use 10nm in my current racebike and a little more wouldnt be a bad thing especially with the added weight of the BMW.
 
Wow. Im glad im not the only one who thinks the front end is vague.
My opinion from my past experience of bikes is the rake and trail is pretty radical.
This i expect to be made to feel more extreme by the hp wheels.
The dds is taking away real connection from the front which with the extreme trail is causing this feeling.
Yesterday i flipped the collar in rear shock to drop back end and raised the front end 2mm by dropping forks through.
It was fractionally better but also it needs more weight over the front so by doing what i did its putting more weight over the back.
Im thinking about stiffer rear spring and extra links in chain to slow steering and put weight back over the front.
Id say the only benefit of the standard geometry would be fast changes of direction. Places like thruxton or silverstone would be a good example.

Front-end vagueness is a common complaint regarding DDC which is why getting it resprung and properly set up is so important.

Most people go to mct. But in the past they couldnt help me with my mupo shock. He said whos ever heard of mupo. Funny thing is mupo are on race winning bikes like the recent win by michele pirro in the spanish championship.
Doesnt fill you full of confidence.
I think the option to switch it all off like it was manual suspension would be megga. I wonder if the 2019 will have this option?
 
MCT Suspension

To be honest I?ve never heard of Mupo Suspension either and I?m willing to bet a lot of others won?t have either. The big three suspension brands you see in UK race paddocks at all levels from Club to National are K-Tech, ?hlins and Bitubo so that doesn?t surprise me in the slightest. As for MCT Suspension, a good percentage of those in the BSB support classes use him. He is also one of only a few suspension tuners that has a great deal of experience with DDC equipped bikes.

True they arent as well know over here but if they just smashed the lap record at imola with mupo i think at least a suspension specialist should have heard of them. I will contact mct over winter for advice though
 
Loads of bikes are using Mupo lately. Most of the Italian championship bikes are on them in the way KTech have dominated over here and there's quite a lot of club and national guys using them this year. Half the Ducati Tri Options guys are on them including many of the winners. Dave the guy who does the distribution here in the UK is mega keen and working really hard to promote them. He travels to a lot of the races where riders are using them to give free support. I've bought the front Pot so I have the option of trying to make the DDC suspension work better but I'm very likely to go to Mupo if I race this bike. The only thing thats stopped me is handy cash and wanting in an ideal world to buy another bike for racing so I can keep this one for Nurburgring and the road.

mupo is big i italy their version of k tech , looks quality I was gonna try it a few years back but thing that stopped me was distrubutor supplied but you had to find your own suspension guy to fit, and after sales settings, back up info etc,,

Dave travels out to fit them in most cases now and will do a free setup whilst he is at it and show you how they work. The Mupo 911 design is pretty cool since you can adjust the spring rate so no need for different stiffness of springs. I'll post some proper info if I end up buying them but I've known Dave from track days for a few years since before he was the Mupo distributor and he was always really happy to help with setup just because of his personal interest despite me never having bought anything off him so it's only right I give him some praise!

How do you change the rate of a spring without changing the spring weight/wind/thickness?
 
Ok by locking off part of the coil you change the ability of the spring to resist... interesting, but there must be downsides surely.
