bigboi Posted March 7 Report Share Posted March 7 Hi all, I just bought a '98 Techno 270 Dougie Lampkin Replica. I'm a very heavy dude and almost bottom out the stock rear spring. Does anyone know any compatible replacement springs available out there, before I go spending hundreds at a custom spring shop? I found this custom shock being sold for 02-08 Betas, I wonder if it could be retrofitted? https://www.omniaracing.net/en/rear-mono-shock-absorber-hagon-for-beta-250-trials-20022008-p-133644.html Quote Link to comment Share on other sites More sharing options...
bigboi Posted March 16 Author Report Share Posted March 16 I return with knowledge! The stock spring is a 49x170mm unit. K-Tech makes a 52x160mm spring for road bikes with rates up to 120N. The 95N spring will fit inside the swingarm of the Techno with custom-made spacers to make up the difference in internal diameter and length. I confirmed this by 3D printing a cylinder of the new spring's dimensions, slotting it into the shock and installing it into the bike. With this and Jitsie's stiffer fork spring on the way, I should be good to go. Will report back once the parts arrive, just in case anyone in the future needs this info.

bigboi Posted March 26 Author Report Share Posted March 26 K-Tech spring fits and feels excellent. (To a newbie, at least.) Jitsie's 38mm Paioli fork spring also fits, with a +7cm (14cm overall) replacement preload spacer. Spacer diameter is 32mm. Quote Link to comment Share on other sites More sharing options...
lineaway Posted March 26 Report Share Posted March 26 Glad you found something. Even in 98 there were not many choices. The 02 to 08 was a side mounted shock with no linkage is why no one awnsered. Go out and have some fun. Quote Link to comment Share on other sites More sharing options...
