I dont think the subs are much different from other one make clubs,a few quid a year maybe........however,no complaint from me ,because in Oz ,postage on the little club mag was more than my subs....I did get burned on used spares not fit for the scrap bin...(not just once either ).......I suspect the reason is the commercial deals with the two Norton biggies,and from this the fact they never have any items manufactured ,again commercial agreements,and manufacture of small run items costs big money ......for instance ,the Ariel club has new S4 conrods made ,at a estimated cost of 2000 quid a set.
