For those that don't know many parts for older Gasgas trials bikes are available from Jim Snell (trialspartsusa). He ships fast and knows everything about them. My 97 is a solid runner and he still has a lot of service parts for it. You need to call him since he does not have parts listed on his website.
I sold my older gasgas enduros even though I liked them because it got harder and harder to get parts once Gofasters and Motocross Center in Europe were no longer options. I do miss them when I ride nasty singletrack...
I just got the SKF rear kit for my '09 from Matto/Gasgaspartsguy.com. Its a really nice kit! No issues at all with ordering, shipping, or installation.
I had a rather interesting conversation with InnTeck, the SKF distributor for these. Only 2 dealers in the entire country sell the complete kit and zero dealers sell the bushing and seal kit.
They said their GG sales have seriously dropped off. Strikes me as not a good sign.
They sold me the bushing and seal kit which I'll just keep as spares and I'll order the complete kits from Matto.
Oh, I have the old Rekluse Z-Start in it and Rekluse no longer has any parts except the thin steels.
Since its just on the other side of the border, my go to is motocrosscenter.com
If i place an order over 50? will get FREE SHIPPING and in 24h, is in my hands!
They have a lot of parts for gasgas, and they reply to any question you may have.
