MOTIV Sigma Tour Pearl Bowling Ball

Keep the length. Bring the move back.

When your benchmark ball reads too soon, a cleaner shape gives you another line to the pocket.

Clear the Front: Atomic Propulsion Pearl Reactive coverstock carries energy through the front of the lane. Watch the ball retain its motion for the turn toward the pins.

Read the Middle: The Sigma symmetrical core revs easily with a low RG design. Its moderate differential gives you useful flare without losing a readable shape.

Work Through Transition: The combination fits medium oil when your earlier rolling equipment starts to lose its downlane response. Change the shape before you give away the pocket.

Balance Traction and Motion: This pearl cover offers more oil traction than the Nebula cover while delivering a defined downlane move. The factory 5000 grit finish supports that balance.

Choose Your Weight: Available in 12 through 16 lb in dark purple, purple, and red pearl. Consumer release was July 8, 2026.

Keep an answer ready when the lane asks for a different shape.
