Sold the old 04 RX-1 with 8000 miles on her, still had the original track. Actually got $1000 more than I paid for it 4 years ago. Of course I bought another Yammie 4 stroke, nothing but Yamaha's for me for over 25 years. I thought that the RX-1 was an awesome machine, only ever had the chaincase bearing fail on me stranding me in the bush. Never changed any bushings or exhaust donuts. I found that the RX-1 didn't corner very well and I am hoping the Apex is better. The Apex has only 1500 miles on it so I am hoping that it will be awhile before I have to do any serious maintenance.
