Well, the lads at Maxton are pretty fast with answering their e-mails. Within one hour I got the following:

- The £300.00 option involves modifying the original damper rod system so there is damping inside the forks. This is a revalve of the damper rod system, we also replace the springs for harder springs.

- The £479.00 option involves completely replacing the fork internals with a modern cartridge damping system. This cartridge is built to suit your rider weight and what you use the bike for. This also comes with harder springs. As part of this conversion we also replace the forks tops with our own. The new Maxton tops have adjustable preload and rebound damping.


Especially the last option looks similar to fitting CBR F2/F3 inner tubes in the stock SV outer tubes. But still a little expensive indeed.

Hi Sarah, do you know roughly how much a fork upgrade would cost at your workshop? I'm booked for a remap but might get the forks sorted too.

I'd stick with the emulator route, I have re-done a couple of sets of Maxton damper rod conversions and they either make a complete damper rod out of aluminium with smaller holes so they can run light oil, but have had a couple of sets making a clonk sound like headraces, down to the size of the valve.

The cartridge conversion uses R6 cartridges which give you preload and rebound adjustment (by taking fork caps off to be minitwin legal) but they never seem to work as well as a good emulator setup, which once setup doesn't really need any fiddling with.

expect to pay £225-£250 for emulators and springs fitted (£180 odd of that parts)

Between Steve and I we have pretty much covered most of the Minitwin paddock

ps Sarah, Just booked Snett on the 5th so will be unpainted, but need to ride it

Yup Rob is a good bloke too..think we both have the monopoly on the minitwin grid at the moment!. Mainly down to running a good setup without having to go too fancy!.

The price Rob suggests is about right..does depend on whether the forks are loose or not but its down to individual needs. Drop me a PM if you need more info.

Rob - Cool looking forward to that - just hope its not raining!. Steve might bell you later anyway regarding the electrical bits you were after...

If you want an interesting, and absurdly expensive, alternative... Traxxion are in full production for their AK-20 cartridge kit for the SV. I'm pretty sure it'd be minitwins legal, and by all accounts it's far andd away the best mod for standard SV forks. Also, amusingly enough, costs $1200US

I dont think the traxxion unit that changes the external look of the fork (IE it has a different fork cap with the rebound adjuster showing) is minitwins legal!!!!!!


Anyway if Matt Bond can wizz round Cadwell in a 1.38 with just fork springs and emmulators i couldnt see the justification in spending nearly £800!!. For that id get a GSXR750/600K4 front end fitted with some 20mm Ohlins kit in it..pound for pound it would work out less once you have sold the SV bits you no longer need!!

Is that so? Thought it was, since it uses the same fork body. I remember seeing photos of a minitwins bike that had CBR internals done, which also had different caps. But then, I don't actually know the rules, just assumed that if that one was legal then these would be

Totally agree that it's crazy money though. It's been quite funny watching Max McAllister's position change on them. At first he was saying "Emulators for the road, or a GSXR swap, these are only for people whose racing class requires stock fork bodies". Now, as soon as people started buying them for street bikes, it's "These are the best things ever for a street bike, you'd have to be mad to fit a GSXR front". Which considering you can fit a stock GSXR front for basically free, once you sell the stock bits, it's quite funny.

maybe its because he is selling the product rather than looking at what works best!.

You dont need anything more than the emmulators and springs.

Yup for minitwins the fork cap must remain as std barring the rule where you can update your older bike with parts from the newer model - IE fit K2 fork caps to the K1 bike to give preload adjustment.

Maybe I'm just cynical, but that's my assumption too... I wonder if that cheating bike's still racing then?
