Lots of questions because I'm very confused.
The downloaded manual says we only have a spring in one of the front forks - true ?
If this is true - whats in the other fork.
Are our forks Damper rod/tube type ?
Are our forks Cartridge type ?
When I see Andreani pictures on these forums, I see two complete cartridge systems - one for each fork ?
If we have simple Damper tube/rod forks - how can they be improved -will Emulators work in them.
If we have Cartridge type forks - why are they so shithouse - I thought cartridges overcame the nasty things like high speed harshness.
When a Suspension expert says he can improve the front forks by "revalving" - what does he mean - do we have valves in there.
As you can see - I have no F...... idea what's inside the things that keep transmitting every single bump in the road through the front of my bike. I'm thinking of welding the inner and outer sections together so I would at least know why it feels harsh.
Thanks for any help - Regards Ray.

These are cartridge forks, but terribly cheap ones.

There are springs and oil in both, but the cartridge in the right fork is a "dummy" and does nothing. The Andreani system uses 2 fully functional cartridges, the one controls rebound, the other compression.

These are not damper rod forks - emulators are not an option.

They are just about the worst performing forks I have experienced in many years.

Tony, I see Hyperpro do a progressive fork spring kit.
What are your thoughts?
Any good or a waste of time?

IMO, you could achieve marginal benefit from changing spring type/rate along with adjusting fluid volume - but don't expect miracles. any improvement is likely to be very small, and this is going to be more effective if the rider is on the "light" side.

Changing springs and fiddling with oil will make it possible to realize more comfort, but noticeable performance improvements are probably off the table..

It's a shame these are not damper rod forks, as at least there would be a much cheaper and more effective fix.

Thanks for the replies.
So - what are our options for the forks.
It would be nice if I could collect all the options in the one thread.
What I understand so far:
Maxton use 1 cartridge in the Right fork and supply a matching spring for the left fork - 255 pounds inc. fitting plus vat - approx $500 AUD (refer Maxton PDF - thanks Jerrycan).
Maxton can supply 2 cartridges - this sounds like the ultimate - 1115 pounds inc fitting plus tax - approx $2200 AUD - ouch.
Andreani system users 2 cartridges - sounds like the ultimate too - anybody got costing please ?.
Member "LOST" mentioned he cut down the spring spacer and added less oil - can he supply a ride report.
Would just better springs (quality and matched to rider weight/style) be a worthwhile improvement.
Tony - I think your right - at least with shitty damper tube/rod we have some reasonably priced improvements that can be made - but replacing the cartridge could be expensive.
At this stage the single cartridge from Maxton seems a good alternative - just being selfish here, I don't really know what that would cost here in Australia.
Anybody got any other ideas that I can add to this.
Regards - Ray.

Thanks Hedonism - is the missing part like the piece in the picture that has 3 piston like things on it.
The downloaded workshop manual now has 2 mistakes - the torque for the oil drain plug and there is only one spring used in the front forks.
If its not rude - how much did the Andreani system cost you. If you didn't pay full price - what is the normal price please so I can add it to this thread.
Regards and thanks for your reply above - Ray.

No... there are 2 springs - one in each fork - but only one operational cartridge.

Ray,

I have the same kit as barfridge, $750 delivered to home, two quotes to install, Ducati dealer $450 and a suspension specialist shop at $290.

They get fitted next week.

The price delivered is sensitive to the exchange rate, no GST as it's under $1,000, but that may change too.

Thanks for all the replies:
Tony - I worded my sentence badly, sorry. The workshop manual says there is only one spring - this is incorrect and the 2nd mistake along with the thread stripping torque value of the oil drain plug.
Bit of a summary on the forks:
Maxton - single cartridge.
Maxton - twin cartridges.
Andreani - twin cartridges.
Member LOST (on the other forum) - cut down spring spacer and less oil.
That's all the choices I have found out so far.
One area still unresearched is modification to the OEM forks. Apparently our forks are similar/same as the MT - 09 and Race Tech in Australia say they have successfully modified those forks (using the OEM setup) - so are our forks easily/successfully able to be modified.
Regards - Ray.

From the info Maxton sent me it sounds like the left fork spring is retained and the right fork gains a cartridge with spring to complement the original left spring.

Thanks Sham61 - I didn't read the PDF from Maxton properly.
it says - "we fit a spring to the GP20 cartridge so when used with the left leg suits your rider weight and what you use the bike for"
I have edited my post above.
Regards - Ray.

Found this from Matris Dampers, Italy. news
Seem to produce various kits for the forks, from springs up to cartridge replacement. Price wise biketorqueracing on ebay.co.uk has cartridge kits for other bikes at £545 so probably the same. They also do shocks which are on ebay at £425 or £595 with hydraulic preload adjuster.

Just to clarify - it is the LEFT fork leg which is the dummy, and has no damping. I know this for certain as I only sent Maxton the right fork leg for their GP20 cartridge conversion.

The results are surprsingly good, just as Richard at Maxton told me they would be, and at the price I'd highly recommend it. Particularly if you've already done the rear, it really does just finsh the job off.
