Motiv Bowling Ball Catalog Stats

A snapshot of every Motiv bowling ball on record: how the catalog splits by brand, coverstock, core symmetry, factory finish and weight block, and how many balls came out each year. The filters narrow every chart on the page at once.

Pearl, solid and hybrid

The three kinds of reactive coverstock. Pearl covers skid through the front of the lane and move harder at the back; solid covers grip sooner for a smoother, stronger read on oil; hybrids sit between the two.

Urethane and polyester

Urethane hooks less, and more evenly, than reactive covers, for control on shorter or flatter patterns. Polyester, or plastic, barely hooks at all: it's the ball for going straight at spares.

Symmetrical and asymmetrical

A symmetrical core is balanced alike around every axis, for a steady, predictable roll. An asymmetrical core isn't, which helps the ball change direction more sharply at the breakpoint.

For how the balls react, see the reaction chart; for their cores, the RG and differential chart. Every ball has its own page under All Balls.
