Suspension Upgrades?
 

Hi there,I'm looking to upgrade the suspension units on my 3YF 660,and was wondering if there were any standard parts from other Yams I could use as an improvement,rather than aftermarket stuff.I'm thing that spares would easier to get hold of if I needed to!
The bike is going to be used for gereral touring,both on and off road.I'm not the lightest of blokes either so I think heavy duty is the key here!!
Any help gratefully accepted.
