  On the lines of the 4-dimensional Kerr black hole we consider the particle
acceleration near a 5-dimensional Kerr black hole which has the two rotation
parameters. It turns out that the center of mass energy of the two equal mass
colliding particles as expected diverges for the extremal black hole and there
is a symmetry in the results for $\theta = 0, \pi/2$. Because of the two
rotation parameters, $r=0$ can be a horizon without being a curvature
singularity. It is shown that the acceleration of particles to high energies
near the 5-D extreme rotating black hole avoids fine-tuning of the angular
momentum of particles.
