Old Suspension Forks, should i be concerned?

Is it a front wheel motor? If so, then the extra unsprung weight will play havoc with the fork's setup and you may well be better off with rigid.
If it's on the back I wouldn't worry, apart from the good advice above on a service and the usual one about check the crown occasionally for cracks. I wouldn't fit one to a tandem but you should be completely fine.

Thanks for your input but no it is a rear hub so it should all be ok. I will be keeping a very regular eye on all things though!
