Owned an 03 liquid silver without reverse. Bought it in 04 with 556 miles, sold it last year with 2800 miles because of family health issues. Best trail sled I've ever owned. Only issue was with the seat (to low). Added a seat from an 05 and found perfection. Never had problems keeping up on any trail with anyone riding anything. On real rough or tight twisties I had to work harder than some but when the trail got big or on lakes/rivers I could stay out front of any stock trailing arm triple. Vipers didn't stand a chance there. Never cared how cold/warm it was. It always ran great. Could putt along with the kids all day or rip it hard with the hotshots without concern. Could get 20 mpg+ when riding responsible or drop to 15ish when racing the river. Most complain about the weight. I'm 52, weigh 175 lbs and had no issues. They are not much heavier than a triple. Add e-start to a triple and they are very close.
My RX was super clean, 8 inch carbide, 144 Woodys Gold down the center, clutched stock, suspension set to my liking, free and smooth rolling. I wasn't interested in a drag race so I kept the track loose enough to avoid ratcheting from 30ish mph and up. Keeping the skid in top notch shape with the track tension set this way made a big difference on the big end. The last long run I had with it was against another 03 liquid silver RX, 05 RX, 700 SRX, and a Viper (not sure what years they were) on the river. Viper was not with us and had a BIG start (over 600ft). Run was about a mile and a half. Caught and passed the Viper within the first mile. Stayed out front of the rest with ease. The dream meter was bouncing off 127mph.
Many don't have much good to say about the RX1 and 4 strokes in general. I still have and love my two strokes but won't knock a 4 stroke. If setup/maintained right and used in the world they were designed for they are GREAT machines.
