@ Maxton customers for fork conversion

Care amici,

There are several folks on here, that have had their bike's forks converted by Maxton with a cartridge system to compression, rebound and pre-load adjustment. Can you pls. clarify one point to me if this is compression AND rebound on BOTH fork legs adjustable or if one side is compression adjustment and the other side rebound while both have compression adjustment?

I am asking because I just got my fork legs back from Hoffmann (www.hh-racetech.de) and his conversion was one side compression, one side rebound (just like the M1R used to work) and I was wondering if this was just related to M1R or a general thing (have asked back, but not an answer yet...) and if maybe Maxton's higher price could be argued by both adjustments on both legs (and if that makes any difference?!?).

The rest seem to be almost the same on both Maxton and Hoffman, they both do throw away all the internals (well - no, they sent them back with the upgraded forks  ;) ) and only keep the tubes, while both tubes get a truing and the lower one get's teflon inserts etc.

Oh - and Keith: how is your conversion in that regards, please?

thanks a lot


EDIT: using the search function ( :-[ ) I think I found the answer...: Seams Maxton fits the GP20 cartridge which is compression AND rebound damping on both legs, but rebound only accessible with the front wheel axel out and there is NO preload-adjustment (which does not matter on a bike that you use only on the road alone OR on the race track, but as with my bikes, I use at least the Jota on the track and on the road, which needs different pre-loads...).

Is that correct as stated or is there anything else that should be considered?
 
Lothar, if you send an email to Maxton about this I'm sure you they will set you straight. I also think that if you want a screw preload system put through your fork caps it wouldn't be a problem. Any competent machinist could do that for you. For my money I'd go with both damping adjustments in each leg; it is the norm for a reason.
 
Hi Tippie,

I compared the prices of Maxtons conversions and they are high to say the least (counting in shipping costs from Germany and back from UK, exchange rates etc. and the same work done on forks as Hoffmann does, you pay roughly 30 - 40 % more with Maxtons without the preload-adjustment already).

The M1R was setup like Hoffmann did with one leg for compression and one for rebound for more than 10 years in the market and tons of bikes like Ducati F1, Laverda 1000SFC, Moto Guzzi Daytona etc. (which even had each of the sides adjustable from the top-nut). According to Hoffmann it makes no big difference for a use-case like I will use the forks for (not for racing, just for road-riding and a track-day once in a while), as the fork is held in several places and the axel alone would keep the fork-legs from moving independently he said. He did not even recommend a fork brace, which surprised me a bit.

I think I'll test the fork first and see how it goes and then I will decide if the next fork will get a different treatment. That'll take a while, as I burned a valve on the SFC during the highway-run...  :-[
 
Lothar,

Can you tell me what a marzocchi conversion at Hoffmann will set you back for.
Is it gabelkit 4 (?700,-) you'll need and can you still use the original 5 peace handlebar.

Regards Robert
 
Hi Robert,

yes, it was Gabelkit 4 for 700? (incl. VAT, plus shipping, which was 6,90? in Germany...). You can still use the original Handlebars on the 1000SFC. If you refer to the "Brevetato", I doubt that will work, as the pre-load-adjuster reaches out roughly 2-3 cm above the fork top nut.

HTH
 
Lothar,

Thanks for the info what is your experience is it a big upgrade compared to the standard fork Marzocchi 38mm.

Regard, Robert
 
Hi Robert,

can't tell as of yet, as the fork has not yet been installed due to the fact that I have to take the SFC apart (burned a valve, cracked frame - the common things, you know...  :( ).

Will tell as soon as it gets ridden. promised!  ;)
 
Busy? Well, naaa - here is my priority list (besides my daily 60 hours a week job):

-finish the pool for my kids (should be done in 1 or two working days; just need to find free days to do that...)
-get the 1000 SFC classic ready (1 stud needs time-sert, some engine maintenance, wiring needs a serious check and some connections replaced, new tires, polishing - hopefully ready).
-get the 1000 SFC (green) stripped and engine reworked, frame welded (strengthening plates, headstock extended with support tubes, triple-clamps extended to fit the longer headstock, all new bearings, fixing the rear-brake issue)
-get the Formula running on the MyECU16M
-turn to the 1000SFC "0001" bike, pull and strip the engine, check for wear, re-assemble and get it running

You see, it just takes me the next 2-3 years to get everything fixed. Assuming I don't get any other project in my way... :-[

You need challenges in your life.


But that many??? :o

:D :D
