Cobra is committed to producing the best 65cc motocrosser period. The 2012 CX65 is the culmination of those efforts, and back for 2012 is our world class chassis: Twin spar HSLA frame, ultra-light aluminum swingarm featuring aircraft bonding technology, three-way adjustable CARD rear shock - all adorned with best-in-class componentry. New for this season is an engine that takes two-stroke technology into the stratosphere! Cobra is proud to announce the world's first direct-acting electronically controlled power valve two-stroke engine. Not only will this power plant deliver the industry standard of usable power to the rear wheel, but it will do so consistently and reliably. Furthermore, shifting is greatly improved with the advent of a new shift mechanism, and an all-new front brake system provides new levels of power and modulation for ultimate control. Last but not least, both wheels are shod with Dunlop GEOMAX MX51 tires for outstanding traction and stability. All this and much more makes the 2012 Cobra CX65 a winning machine!
