2011 Cobra CX50 JR
MSRP $3,498

It should not come as a surprise that the CX50JR was won every single AMA national championship title at Loretta Lynn’s since the class’ inception in 1997. While other manufacturers are turning their back on the smallest racers, Cobra is fully embracing them with several important improvements for next season. Topping the list is an all-new rear disc brake for improve stopping power and better brake feel. The frame also receives several updates that reduce weight and add strength. To top it all off, the JR engine gets all of the top-end and transmission improvements that its big brother, the King 50, enjoys.
