For parts, I suggest becoming a lifetime member of KTMtalk and ordering parts through Munn via the "shop online" button at KTMtalk's site.
The membership costs 100 (I think).
The discount is significant- I've saved many hundreds beyond the cost of the membership. Munn is a high-volume dealer who carries a large inventory- I've never had a backorder. Helpful on the phone, and know all the pitfalls (like slightly different clutch plates from Rekluse/non Rekluse RFS motors etc. Odd bits like that.
Sometimes local dealers will discount parts, but rarely and they usually don't have the knowledge Munn does.
