The new Mxz look lower and wider sitting next to the XRS. The new gen 4 has a extra inch of travel?? Where? Reminded me of the last Mach Zs front end wide and low. The new Xrs didn't offer anything new except a silver tunnel.. Still cant order a 1.6 Ice Cobra on a MXZ or XRS. ?? THAT SUCKS! If you want to feel the power of the new 850 you have to pay big. Msrp on the 850 Mxz X ice ripper, Q/A electric start is $14,549 ouch! Add about two hundred for a gade. I didn't pay that for my XRS? TnT 850 =12,449 add two hundred for white and black.
