Member Contributer Mohawk Posted December 13, 2019 Member Contributer Share Posted December 13, 2019 YSS Fork Spring Table View File Having spent ages trying to find compatible fork springs for an older bike, I came accross this list on the YSS Thailand site & thought it would be a great cross reference for anyone looking for a fork spring, when they can't find what they need for the specific model ! I had planned to use VFR springs to improve my buddies FJ forks when I refurbed them, but turns out Yamaha use a thicker wall on their 41mm forks, so the VFR springs (35mm OD) won't fit ! I was able to use this file to cross reference the early FJ1200 spring (485mmx33.5mmx0.65Kg/mm) with an XJ900S from 94-03 years which is 490mmx33.5mmx0.8-1.6Kg/mm (progressive), so only 5mm longer but stiffer, just what I needed 🙂 Hope it helps others.

Member Contributer Marvelicious Posted December 14, 2019 Member Contributer Share Posted December 14, 2019 I truly appreciate this kind of info. I'm pretty brand agnostic when it comes to parts. If it fits and works, it's the right part! Quote Link to comment Share on other sites More sharing options...

Member Contributer raYzerman Posted December 14, 2019 Member Contributer Share Posted December 14, 2019 Has anyone explored the straight rate spring options from RaceTech or some of the other North American suppliers like Sonic and Traxxion? A spring upgrade is likely on my list....... Quote Link to comment Share on other sites More sharing options...
Member Contributer Marvelicious Posted December 14, 2019 Member Contributer Share Posted December 14, 2019 I've got RaceTech springs in my forks. I used their recommended spring (for my weight on a VFR) with custom damping, and they feel excellent. Getting the spring right is the first piece in the puzzle, but you have to get the damping right as well. Of course, getting the front end right just highlighted the problems with the rear... I'm using one of Jamie's shocks on that end. It all works together and getting it right isn't cheap, but the end result was huge for me... I'm pretty big though, so the stock suspension was seriously out of its comfort zone. Quote Link to comment Share on other sites More sharing options...

Plus a Nitrox Race shock on the rear, with the brake delink & loss of 35Kg it handles & brakes like a CBR600RR now 👍😎 Quote Link to comment Share on other sites More sharing options...
