About PBI Sprockets
Founded and headquartered in Oregon, USA, PBI Sprockets has built a reputation as one of the most trusted names in high-performance motorcycle drivetrain components. For riders who demand precision, durability, and consistent performance, PBI delivers products engineered to exacting standards that hold up mile after mile — whether on the street, the track, or the trail.
Precision Engineering at the Core
What sets PBI apart is its commitment to CNC precision machining. Every front and mainshaft sprocket is cut from high-grade chromoly steel, then heat-treated and plated to maximize wear resistance and extend service life. This isn't off-the-shelf hardware — it's purpose-built performance. Riders looking for motorcycle sprockets that can withstand aggressive riding conditions consistently turn to PBI for this reason.
Beyond steel, PBI is equally celebrated for its aluminum rear sprockets — lightweight alternatives that reduce unsprung weight without sacrificing strength. The brand's aluminum sprocket lineup has earned near-legendary status among motocross and off-road enthusiasts who want every possible advantage.

More Than Just Sprockets
While sprockets are PBI's calling card, the brand's precision machining expertise also extends into critical engine drivetrain components. Their engine timing chain parts and engine timing idler sprockets reflect the same manufacturing philosophy: tight tolerances, quality materials, and long-term reliability. For any application where a sprocket, chain, or rotating drivetrain component is in play, PBI's engineering pedigree makes them a compelling choice.
