I have a 2002. Ugghhh. It takes forever to service this thing. Jeesh. I can change the trans oil and coolant in my kids' KTM quicker than i can fill the oil in the GG transmission. Rear suspension service took forever, but at least i was able to swap out bad bearings and bushings that I had to leave last year 'cause I ran out of time to fix it properly (no nearby dealer, and I was in a pinch, so I just lubed it).
I found some 2216-2RS sealed needle bearings for the rear suspension linkage, so I'll let you know how that works out. Double seals might be the cat's meow.
That being said, the bike has been stone reliable. I took the exhaust off today (rust hole...go figure. That Eline guard traps moisture), looked at the 5 year old piston (i lug the bike, and didn't ride too much in the past three years...work and broken wrists), and it look great. 10 year old clutch, crank, main bearings, trans, etc. Just replaced my chain slider after 5 years.
Yes, the thing drives me nuts. The engineer who came up with the clutch bleeder is a fool. I can't imagine anybody coming up with a worse design for the kickstand. KTM did a much better job of designing needle bearing bushing/seals. (I've yet to see anything but light polish on a KTM swing arm bearing). The PDS is really attractive in terms of service. I've done 2 heim joints in 5 years. Can't complain there.
Of course, this is on a 10 year old bike. I'd really like to take apart a 2012.
The old bikes were quirky, but i've spend nearly nothing for spare parts/broken parts. In that respect, they're awesome. If you do your maintenance, the bike will reward you.
Would I buy another? Maybe, if this 2002 ever craps out. I am gonna' buy a new exhaust, drink some beer once I finish my spring service, and ride it another year.
