Just an update on the softer springs for the OE shock from Hitchcocks that I fitted.
I've covered about 1000mls on some pretty rough roads since fitting. These OE shocks now work fine, much softer than the before but not too soft.
I'm 170lb and one up I'm running on the second preload notch. I had a pillion on around the same weight as me and I had to put it on the max preload (4th notch). If your combined weight is greater than this (340lb) I think you'd need to put the original springs back on
Just for reference:
The OE shock springs are 18kg/cm.
The replacements from Hitchcocks are 13.5kg/cm which sounds kinda soft but remember the OE shocks are pretty heavily damped.
The Hitchcocks part no. is 200043, cost is about $40 plus shipping.
Overall it's a cheap alternative to the Hagons.
cheers - thanks again for all the advice.
