Gasgas ec front suspension options

After some help/advice.

I have a 2000 gasgas ec250. I am looking to change the conventional forks for USD. Does anybody know of any from other bikes that will fit?

I used to race a lot of motocross and do the occasional enduro but due to finances can no longer afford a proper mxer. I got this dirt cheap and must admit I am impressed. I think the ohlins rear shock has enough adjustments to tackle whatever is thrown at it. On the other hand - can't find middle ground with the front end.

So if anybody has any idea what USD forks will simply swap (don't mind changing the yokes)????!!

Any advice would be greatly appreciated :).

Many thanks.
Sam
 
There are many options. Easiest swap in my mind is to just get an entire front end, including wheel off of a pre aluminum frame YZ. The KYB fork is a good unit, and the triple clamp is the same offset. I think it will slide in and bolt right on to the front of your bike too. Won't promise, but I think it's true. The steering stem, from what I remember is the same dimensions.

Does your bike have the 50mm conventional WP on it? Or is is the Marzocchi Magnum 45 with the blue clickers on top?

The WP Extreme 50mm fork is a very fine piece of bouncy. There should be no reason that it could not conform to your standards unless your name is Jeremy McGrath and you are tackling large supercross obstacles.

If you want to get rid of the forks (if they are WP Extreme 50's), I may have a buyer for your entire fron end.
 
I am thinking of going the other way. I am a B rider and ride mostly in extreme rocks and technical terrain. I have always preferred conventional forks over any USDs I've used for where I ride. I have an 01 GG 250 xc and discovered after purchase that some previous owner had the WP forks shortened by 2.5 inches. I am 6'2" and 230. for the time being I've been using the Showas off of my 04 CRF 250 Honda which are USDs but are the best I've used that are stock, but at some point I'll need to put those back on the Honda. No, it wasn't an easy fit, I had to do some fabrication to make it work so don't try it unless you can really do machine work. If I had to do it again I wouldn't have.

Anyway, if I want to switch to conventionals, what is my best options for my ability, size, and terrain? I have an extra set of DRZ conventional forks that I have had revalved for a DRZ I used to have and I really like them but I have no idea what clamps to use. I also have a DRZ front wheel and brakes, whole front end but I'd really rather use a factory GG setup if possible. I know nothing about WPs or Zokes really. Most of my bikes have had Japanese suspension or WPs which I didn't make any changes to. I will be wanting conventionals that don't have alot of underhang below the axel. The ones I can think of are whatever came on Honda XR 650s, (not the XLR which does have underhang, although they are fantastic other than than with a fork brace), DRZ-E forks which are adjustable for rebound and compression, and older KTM-WPs, the 50mm Extreme WPs being the best I've tried. If necessary I can make my own fork brace for some of the smaller diameter conventionals if one is not available aftermarket.

Just to clarify, I am exclusively an Enduro and H.S. rider, don't jump anything unless they force me to on a Scramble course, and mostly ride in some of the most extreme rocky technical terrain I've seen in the nation, so conventional forks seem to flex and soak up the nasties best in my opinion. I have spent plenty of $ trying to get various USDs to be as responsive and travel freely through the stroke as some basic conventional forks. I'm tired of wasting money on revalves and oil changes, etc. I have also noticed that conventional forks blow seals and wear out bushings much more slowly than even the best USDs. I am actually faster on my stock slow motored, undersuspended DRZ than on my fast GG, but I keep thinking that if I can just get the front end on the GG to actually be plush in extreme rocks and soaking up logs and the like it will be the ticket.

Any help will be appreciated, Jeff.
 
I know a couple guys who do this to all their new bikes, mostly KTMs. They use conventional twin chamber Showas from 96-98 RM250s. They make custom sleeves to shim the forks in the triple clamps, and mostly use the Suzuki wheel. Here are a few sets for sale by one of the guys.

We ride in extreme rocks too. I'm at the point where I like the bike to handle some faster stuff too, as long as it doesn't deflect and beat me up in the rocks. I don't need a couch, just something I can trust not to bite me.
 
DRZ Showa is open chamber, RM Showa is closed chamber. These get really good reviews from these guys, who are B to AA riders who ride the rocks here all the time.
 
Agree on the twin chamber Showa forks. I love those forks. The WP Extreme and the '96-'98 Showa conventionals are amazing. They are big enough not to be horribly flexy, and provide amazing action. The DRZ fork isn't even close, not that it can't be good. Might be just what you want?..
 
Got them on my rm125, they were the up there with rg3 Showa with coated internals, ttx Sachs and hadn't been serviced in 8 years, I can't wait to try them when ive finished the rebuild, the seals were also full of grit and the bushing were completely gone. Amazing that they still worked.
 
Any info appreciated, thanks for what I've gotten so far. True, DRZ forks are small and simple, but they work better in rocks than most other forks I've used. They do flex but a fork brace fixes that.

Any thoughts on early GG conventional forks for my 01? Any simple bolt on mods to try rather than having to have shims made or clamps machined for the DRZ forks?

Flex is not an issue for me, I got used to that in the 70s and 80s. Lack of steering precision is rarely a factor to me anyway, again maybe riding the old bikes makes me not notice it? I go faster with forks that don't beat up my shoulders, wrists, back, etc. My beat up body is my main limiting factor, any way to make a bike soak up terrain is a good thing.
