At highest point of globe of death , the energy equation will be
mg 2R + \frac{1}{2} m v^{2} = m g h
Where R is the radius of the globe of death.
We also know at highest point mototcyclist needs to cancel gravityto prevent from falling down.
Which will be provided by the centripetal acceleration.
thus \frac{v^{2}}{R} = g
v2 = Rg
substituting it in the energy equation and solving we get
h = \frac{5R}{2}
h =50m
