Dragontest Posted July 26, 2022 Report Share Posted July 26, 2022 Hi where are people getting replacement simplex primary chains from, now in-motion is out of stock of these chains? What is the correct size of chain? I just wondered if a different manufacturer makes something that’s a direct replacement for the joresa chain? Any help in getting a affordable replacement is very much appreciated. thanks 🙏 Quote Link to comment Share on other sites More sharing options...
woody Posted July 26, 2022 Report Share Posted July 26, 2022 I've tried several chain manufacturers here and none can match the size, even Regina who used to make them, You can still buy a Joresa chain from dealers in Spain and also France Trial Classic sell them 2 Quote Link to comment Share on other sites More sharing options...
bullylover Posted July 27, 2022 Report Share Posted July 27, 2022 Maybe also try Bultaco Classic in the USA or Bultaco Australia. They may have some left. 1 Quote Link to comment Share on other sites More sharing options...

carl ekblom Posted July 29, 2022 Report Share Posted July 29, 2022 As far as I know the duplex chain also use another tensioner, clutch basket and engine sprocket. Also think the ratio might be slightly different, but I have read (somewhere) that trials people do the conversation. Original Joresa single chain is special dimension 1 Quote Link to comment Share on other sites More sharing options...
pschrauber Posted July 30, 2022 Report Share Posted July 30, 2022 There are some dealers in the US, that still have and sell them, too as replicas. Try there. Then there is Orlando Calonder in Buchs near Vaduz in Switzerland / Lichtenstein he has all kind of parts and stuff for Bultaco you never believed still exists, but he is not doing business with Britain. If you know someone from the continent that can order for you no problem. Quote Link to comment Share on other sites More sharing options...
