MX Z® Adrenaline 600It's more than a performance sled. It’s the performance standard. Our engineers and designers didn’t hold back with this one. The 2010 MX Z®. Intense maneuverability. Breathtaking acceleration and plenty of other reasons to call it the performance standard. Built on the incredibly light REV-X platform, it had to have both a two-stroke and four-stroke engine option. It was only fair. Every rider deserves a little trail time with the best cross-country sled on the planet. MX Z® Adrenaline The sharp-handling performance standard.
