Phazers were nearly identical past 2007. The 2007 had a number of fixes that were taken care of by Yamaha if you opted for the 5 year YES. 2008 on, they addressed cooling issues, skid component strength etc. But mostly, they were nearly the same.
They dropped the Phazer FX after year one, as it was confusing for the consumer in that they were all in the "FX"chassis. So that to went away. Mostly, you could get a Phazer Standard, GT (trails) RTX (bumps) and MTX (extended track and lug) Then the XTX was released in 144 with 1.5" Freeride. The Venture Lite and MP were a form of 2-up phazer as well with the 500cc twin.
Overall, most will agree (that owned and rode one) that it was a fun sled up to 60mph. Clutching and a 1.5" track would liven it up even further as it had lots of torque in comparison to HP. Many will agree to avoid the Standard for the entry level shocks and lack of reverse. Air shocks of the RTX were hit or miss, but good when setup properly. Many like the coil over clicker shocks. Mine were great once revalved by HyGear and setup for weight.
Most GT's and Standards had a 1" Hacksaw track, where FX and RTX units usually had the ripsaw track.
I do doubt an ounce of plastic has changed in all the years other than color. Same goes for the seat. Skis may have been the same as well, other than the wider MTX skis. Put on a set of Dooley Carbides, and the stockers worked.
Bounce any questions back. But if you are looking at used, run the VIN at a dealership, and they can give you a history of what was done and covered by warranty. This is especially true if you find a deal on a 2007. Proceed with caution, but don't dismiss it altogether.
Good luck!
