Forums

Hello

Below is the reply i got from Maxton when enquiring about suspension modifications. Has anyone tried this and what are the results? this is not a cheap option.

thanks

Mark Thanks for your enquiry, we can help you out with the problem on your forksbut have no spec sheet for you to read. We convert your forks, but not bymodifying the existing internals. We throw everything inside the fork awayand start again with our internals. The internals we supply is our own GP20 cartridge style damping system. Thecartridge system is the same type of internal as what you would find in anymodern front fork. It has been manufactured and developed by our ownengineers and has pistons and shim stacks for the rebound and compressiondamping. The Cartridge also has needle valves so you can adjust thedamping. The damping adjusters are external, so you can change the dampingwithout having to strip the forks down, but we hide the adjusters to keepthe classic appearance. As part of the conversion we also machine new forktops to take the new cartridges and damping adjusters. We also fit newsprings. Every Maxton GP20 cartridge is built to order, the reason for this is tovalve and spring the cartridges to suit the fork, the bike, the ridersweight and what they are using the bike for. Once the cartridge has beenmanufactured we then fit the cartridge to the fork to make sure it workscorrectly. In most conversions we have to modify the original bottomsliders and stanchions so our cartridge will fit and work properly. Theforks are then returned to you fully serviced with new seals and the springpreload and damping set up. The Maxton GP20 cartridge costs between £295.00 and £495.00 + V.A.T.Depending on how adjustable you want the cartridge to be. For £295.00 +V.A.T the cartridge is adjustable for rebound damping. For £495.00 + V.A.Tthe cartridge is adjustable for rebound and compression damping. Alladjustment can be made without having to strip the forks down. To service the forks with new seals and install the cartridges costs £124.00+ V.A.T. In some cases there are also charges for any extra work to get theforks to work correctly. In Norton and Seeley conversions we machine newbushes for both top and bottom sliders, the bushes are made from a hardwearing frictionless plastic called Delrin. The bushes cost an extra £60.00+ V.A.T. In some cases we also have to get the original sliders honed asthe bore of the slider is not machined very well. The cost of honing thesliders is £80.00 + V.A.T for the pair. In some Triumph forks the seal isheld in place with friction on the outside diameter. We machine a groove inthe bottom slider, so the seal is retained with a cir-clip. This costs anextra £50.00 + V.A.T. The cartridge conversion fits inside most forks with stanchions that have anoutside diameter of 35mm or bigger. In some Honda forks the stanchions are35mm outside diameter, but the internal diameter of the stanchion is toosmall for the cartridge to work. For these forks we supply new Hard Chromedstanchions with a larger internal diameter. These cost £200.00 + V.A.T apair. If you need any more information about the modification we carry out you canring me on the telephone number above, if you cannot get through fax me yournumber and I'll ring you back as our phone can be very busy. IF YOU LIVE IN A COUNTRY WITHIN THE E.E.C THEN YOU WILL HAVE TO PAY U.KV.A.T, UNLESS YOU HAVE A TAX CODE FOR YOUR COUNTRY. Regards RichardMaxton Engineering

Why don't you take a look at the Lansdowne conversion by John Bould, about £230. Do a search and it should come up. Lots of info on the accessnorton site. Seems to be very nicely made and well received.

You have to ask yourself what you want to improve about your forks and what sort of riding you do. If you want to improve the overall handling of a Commando It would be worth Googling "The worlds straightest Commando" It might give you some food for thought. It might horrify you when you read how inaccurate most Commando frames are from new. If you Google "Roadholder fork Conversions" you will find an American company called Cosentino engineering making a Showa fork conversion for about $795. I would be looking at Japanese forks from a breaker and reap the benefit of twin discs. The later Yamaha Diversions have two discs and the forks are about the right length and the bike is a similar weight to a Commando. You may even be able to fit the rear wheel and have a half decent rear brake. (No spokes to clean) A friend of mine had his VFR Honda converted by Maxton and it cost him £1000. I believe it is possible to fit the guts from CBR 600 forks to Roadholders and there are plenty of those around as the older ones fall from favour by the trackday / racing fraternity.

I have had a rear shock custom built for an modern bike by Maxton. It was very good but...it did take a long time to make.

I had the Maxton fork conversion on my VFR750. It was the best thing I did to the bike, 10 years it cost me £230 which was good value at the time considering this is a bespoke service supplying great quality kit. As well as sorting out springing and dampening rates, Maxton used stiffer springs but with pre-load wound right down to reduce wheelbase / speed up steering. This resulted in a great improvement at high speed cornering and overall more precise steering. I've recently sold my VFR750 to a guy who had a newer VFR800. he can't get over how much better the handling is on my 750. I can't recommend them enough, if i wasn't thinking of selling the Commando 750 to fund one of the new ones, I'd make this change myself.
