Wow, a lot to read here. Thanks everyone. I think I'm back to square one. Someone at the Hiawatha in ER let me test ride a Rev several years ago and I remember feeling very awkward. Since then I have had two hips replaced and I have crappy knees. I have an Apex seat on my RX-1, and I like the positioning, but the back of my butt rubs on the seat back something fierce and it prevents me from stretching my legs. I figured that maybe it was just me on that old Rev, but if they didn't change it till the XP, and from all of your comments, I'm pretty sure I'm not interested in pre XP's. Guess I have to up the ante for something newer if I want a Doo.
Yamaha guys: ever get to that point where your Yamaha is SO reliable and predictable that it just gets kind of boring and you want something different? It happened with my SRX and Viper, now it's happening with my RX-1. Actually, the RX-1 is tippy, heavy, the pro-action doesn't do it for me anymore, and I'm tired of cleaning the carbs EVERY year. I love the engine, but I want something I can "throw around" a little bit without it trying to tip over on me. Something with a current rear suspension. I figured the SDI with its economy and emissions would be somewhat comparable to a 4-stroke. I never really had a huge problem with two-strokes to begin with. Anyway, my ideal sled (trail sled for me) would be lighter, economical, have a relaxed but forward ride, 121" track, good wind protection, great rear suspension, have reverse, and not be carb'ed.
Back to the drawing board.
