Q. I am confused between Jupiter standard and Jupiter ZX disc on the basis of comfortable ride, brakes wise, led lighting vs halogen and performance wise. I have driven both of them and found ZX disc better than standard pick up wise, sound of horn, brakes etc. as listed above but salesmen have told me its only because of since STD one is being daily used in test drive and ZX disc being not i.e. it is new. Kindly tell me which one is better in comparison with performance wise?
