84 XR500R Rear Spring Rate?

Recommended Posts

Anybody know what the stock rear shock spring rate is on a 1984 XR500R? Race Tech web site says 9.75kg/mm. That sounds huge can that be right? Eibach has 3 sizes available 5.8,6.3 and 7.6kg/mm. I think I need a heaver spring as mine is pretty sacked out. I'm checking sag tonight so I'll know for sure. Just checking to see what was a available in case I need one.

 

Thanks

You can get real close to your spring rate by using a Spring Rate Calculator, you just need to know the number of coils (don't count the last 2 that are seated), the outside diameter and the diameter of the wire (spring material).  Take a few measurements and use the average:

Yes, most big hondas came with 9.0-9.5 spring stock.  That's for a 165lb ish rider. 

 For my 225lbs I need an 11.0-11.5
