Thanks

i absolutly love it....
its has been a great sled,
if you go to hardcoresledder.com in the manitoba section, you will see a post riding from thompson to setting lake when.....
there is a video of my crashing it
all ok tho, only lost the reverse handle!
cheers

I'm very pleased with mine also.
IMO, its the best all around 07 sled available - especially if your an aggressive rider, and even more so if you want to put on lots of miles per season.
I am extremely picky and always seeking mechanical perfection so there are a few things I intend to improve further on the sled. What I really like about the sled is you get a fantastic package with pretty much the best of everything available from Yamaha (for 2007). Every piece of the sled is tried and true technology that was the most durable design out there (for example the rear suspension first came out in the 05 Vector, and the chassis and engine are from the 06 Apex, but both were originally based on the 03 RX-1)
It is the most comfortable sled I've ever ridden and you feel like you've become one with the machine and can ride it for hour after hour. The riding position is perfect IMO with the mass central, taller handlebar, rider forward position - but its not as extreme as the REV and is much more comfortable. The extra firm seat seems a little too firm at first, but after you spend several hours on it you'll appreciate the seat (at least I do). Again as close to perfection as you can get IMO. Its a great sled for doing just about everything from riding very aggressively, ditch banging, jumping, high speed trails, and as well as long distance cruising (of course its fairly heavy so there are better sleds out there for specific things such as ditch banging or jumping without the need for high speed performance).
The Apex motor is incredible. Smooth, powerful, incredible throttle response, durable, decent fuel economy, etc. I do wish the fuel economy was improved a little and over higher miles the exhaust donuts often need replacing (all Apexs and Attacks).
The drive train is pretty much rock solid and with the 22/38 gears (lower gear ratio than the standard Apex line) you get the best real world performance (snow covered trails, snow covered lakes, corner to corner, on/off trailers without smoking the belt, etc.). The back shifting and clutching performance in all snow conditions is very good. The only minor issue is at least some of the 07's had the older style 06 magnesium chaincase cover that was prone to leaking (mine did). Yamaha will update it to a new cover design if there's an issue and then its rock solid.
The front suspension with the Fox floats works incredibly well for soaking up the bumps and its virtually impossible to bottom out (I never have that I know of). The only compromise is the Fox floats are very soft as far as their effective spring rate until they are compressed a fair bit (then they stiffen quickly). This increases the body roll in corners. Installing an aftermarket 13mm sway bar makes it corner allot better.
The rear suspension is very durable and can be worked hard without worrying about breaking parts. The suspension first came out in the 05 Vector and was very durable then, it was improved and used in the 06 Nytro and then strengthened further (extra gusseting, and billet components) and used in the 07 RTX. Unfortunately the stock calibration leaves a little to be desired for most of us (apparently the calibration has been updated for 2008). Its not horrible if you're willing to accept a harsher ride, but the shock valving has too much low speed damping compared to high speed which gives you a harsher ride and still allows it to bottom out. Another issue is if you're heavier the ride height is too low so you loose the use of a good portion of the suspension travel. Adding "anti-bottomers" helps out with the bottoming out, but unless you stiffen up the clicker shock a fair bit you'll start to get kick back over larger bumps. A shock revalve combined with torsion springs with more preload (if you're over ~190 lbs) would make the suspensions performance top notch. I ended up having the springs re-arched and the ride is very good for aggressive riding with the clicker shock stiffened up (but it could be even better with a revalve). Another issue that all 06-07's have is the rubber on the idler wheels tends to delaminate and the bearings go quickly if you ride at high speeds allot. Modifying the suspension to accept 2004 RX-1 idler wheels gives you ultra-reliability if that's something you need. One final issue that many seem to have (mine included) is the new for the 07 RTX front pivot arm upper bushings crack and the flange breaks off. These bushings have been back ordered pretty much all season so I had some made out of Oilite (bronze) and they worked perfectly.
The one other complaint for my riding style is the fuel tank is too small for the fuel economy. If you ride it moderately aggressively the low fuel light turns on around 80-90 miles and its pretty much out of gas by 110-120 miles. If you ride it slowly the fuel economy does increase substantially though. For next season I intend to install a custom fuel tank in the nose and hook it up "tour buddy" style so the nose tank gets used first and then the main tank. There is a fairly large space in the nose that could be used for this.
One other issue I had was premature hyfax wear. I'm not sure if this was aggravated by my choice of tracks (I replaced the Ripsaw with a 1" Predator), but I completely resolved it by installing Skidoo anti-ratchet drivers, running the track loose and bending the snowflap down to capture more snow. I also installed the optional pair of extra idler wheels. At this point you can pretty much ride my sled on zero snow and the hyfax hasn't gone yet.
So in summary you get an incredible package with the best of everything available in 2007 from Yamaha. If you're a lighter rider the performance is extremely good in every way. You really need to ride one to appreciate the incredible throttle response and overall performance. With some suspension calibration tweaks (revalved shocks primarily) it would be as close to perfection as I could imagine.
I think in the future the new FX Nytro RTX will become the best overall sled for my riding style, but I for one want to give it a few years to get any bugs worked out before I would consider one (almost everything is new for 08 or highly redesigned with it). My one design/spec complaint with it is again the fuel tank is too small since I want the same fuel range as a REV with a 600 SDI (it would need an absolutely incredible 29+ mpg for its 6.2 gallon tank to do this - Canadian/Imperial units). Time will tell...
