Thanks for your enquiry, we can help you out with the problem on your
forks but have no spec sheet for you to read.
We convert your forks, but not by modifying the existing internals. We
throw everything inside the fork away and start again with our internals.
The internals we supply is our own GP20 cartridge style damping system.
The cartridge system is the same type of internal as what you would find
in any modern front fork. It has been manufactured and developed by our
own engineers and has pistons and shim stacks for the rebound and
compression damping. The Cartridge also has needle valves so you can
damping. The damping adjusters are external, so you can change the damping
without having to strip the forks down, but we hide the adjusters to keep
the classic appearance. As part of the conversion we also machine new
fork tops to take the new cartridges and damping adjusters. We also fit
Every Maxton GP20 cartridge is built to order, the reason for this is to
valve and spring the cartridges to suit the fork, the bike, the riders
weight and what they are using the bike for. Once the cartridge has been
manufactured we then fit the cartridge to the fork to make sure it works
correctly. In most conversions we have to modify the original bottom
sliders and stanchions so our cartridge will fit and work properly. The
forks are then returned to you fully serviced with new seals and the
spring preload and damping set up.
The Maxton GP20 cartridge costs between Â£330.00 and Â£530.00 + V.A.T.
Depending on how adjustable you want the cartridge to be.
- for Â£340.00 + V.A.T the cartridge is adjustable for rebound damping.
- for Â£540.00 + V.A.T the cartridge is adjustable for rebound and
All adjustment can be made without having to strip the forks down.
To service the forks with new seals and install the cartridges costs
Â£140.00 + V.A.T. In some cases there are also charges for any extra work to get the forks to work correctly. In Norton and Seeley conversions we machine new bushes for both top and bottom sliders, the bushes are made from a hard wearing frictionless plastic called Delrin. The bushes cost an extra Â£80.00 + V.A.T. In some cases we also have to get the original sliders honed as the bore of the slider is not machined very well. The cost of honing the sliders is Â£80.00 + V.A.T for the pair. In some
Triumph forks the seal is held in place with friction on the outside
diameter. We machine a groove in the bottom slider, so the seal is retained with a cir-clip. This costs an extra Â£50.00 + V.A.T.
The cartridge conversion fits inside most forks with stanchions that have
an outside diameter of 35mm or bigger. In some H**** forks the stanchions are 35mm outside diameter, but the internal diameter of the stanchion is too small for the cartridge to work. For these forks we supply new Hard Chromed stanchions with a larger internal diameter. These cost Â£200.00 +V.A.T a Pair.
If you need any more information about the modification we carry out you
can ring me on the telephone number above, if you cannot get through fax
me your number and I'll ring you back as our phone can be very busy.

Maxton kit is superb but they aren't a charity and you get what you pay for, but I was wondering if a cartridge fork internals from another production bike could be fitted into the original forks...... it would still be a massive improvement over stock.... any ideas?
