Can anyone tell me the spring rate, free length and possibly ID and OD used in a TYZ, the manual usually would have these details.

    Just found my manual whilst looking for an Ossa one...

    Spring free length is 160mm

    Spring rate is 7kg/mm or 392lbs/in

    It doesn't give the spring ID or OD but somewhere I may have an old knackered shock so I'll measure it if I can find it.

    Not sure which year bike this manual is for now but I'm guessing the shocks were probably the same spec. It is for serial number 4GG-28199-80 according to the front cover.

    Found the shock - OD of the spring is 80mm, the spring coil/wire thickness is 10mm so ID is 60mm.
