1999 Arctic Cat ZRT 600

An M10 is a after market rear suspension. It has more travle and better geometry and better FOX shocks than the stock suspension. They are over $1000. It makes for a great ride, and a smooth landing when you do jumps and stuff. Fully adjustable http://www.teamfast.com/products/m10-ss/#/images/product/galleries/M10-SS/m10ss_med.jpg

I know there a re a lot of sleds for sale right now, its that time of year. This one is super clean, well taken care of and has some sweet options.
