The 'Zen' you are referring to is no longer in production nor are it's engines!!.This is the current Zen model with engine specs.....
Max Power (bhp/rpm) 64 / 6,200
Max Torque (Nm/rpm) 84 / 3,500
Engine Capacity (cc) 1061
Engine Type 4 cyl
India was the sole production hub for the old Zen model and if the engines in the current Cultus are the same as the old Zen, then my guess would be a whole lotta engines just crossed the Wagah border, don't you think??....lol!...
