Been trying lots of suspension specialists to see if I could get a lighter shock springs for the standard sachs rear shock but no one seams to list them I decided to take off the spring and see if I could source them by measurement. Spring length 162mm ID is 52.5mm and from my internet research the rate is 90Nm. I had to had a set of TTX springs from my daytona 675. Spring length 158mm ID 51.5mm From this table I found elsewhere it looks like I need a 75Nm rate as I am 65kgs. Rider Weight (In Gear) - Spring Rate 150 Lbs. - 75Nm 170 Lbs. - 80Nm 190 Lbs. - 85Nm 210 Lbs. - 90Nm 230 Lbs. - 95Nm 250 Lbs. - 100Nm Luckily I already had a 75Nm spring So all I need to do is make it fit. Looking at the top and bottom shock mounting collars, I figured I could just skim 1mm off them. 5 minutes on the lathe ... job done and hey presto - I now have a bunch of springs I can try. If anyone else wants this done - happy to oblige. Ohlins springs from Kais Suspension were originally around £80 each including postage.
Does your shock guard no longer fit or is that just for reference? JoeP was telling me that the Ohlins is MUCH fatter Sent from my iPhone using Tapatalk
hello - I left the shock guard off as I'm playing with the preload at the minute. The standard Sachs spring is 90Nm. I have a 90Nm Ohlins TTX spring and its virtually the same as the Sachs standard one .. actually 1mm thinner. The one in the picture i have put in is a 75Nm ohlins spring which is a lot thinner.
