Track Bowling Balls. Kinetic relates to the motion of material bodies and the forces and energy associated there within. Kinetic features a newly designed low mass bias core called Shuttle and a new veneer called UMP GEN 1. The best way to describe Kinetic's motion is simply SkidFlip. Using a low mass bias designed core shape we have created a ball that is great for medium to heavy conditions and works well when you need to get the ball to flip on the backend.
