You really need to get to know someone at the local shop and get a discount. I get many of my aftermarket RM parts at the Honda shop about 1/2 mile from my house. The parts guy there gives me pretty good discounts off most of the stuff - I bought one of the expensive plugs last year for about $20. Still expensive, but I only go through one or two plugs a year and haven't fouled one yet.
Chili - maybe you're right about the clutches now, but I haven't been particularly impressed with mine.
Love the rest of the bike, though.
