King Bearings XP Race Main Bearings STD Grade 4 Suzuki Hayabusa GSX1300R 2008-2017 (Min Thickness 1.503 Max Thickness 1.507)
Today’s race engines make more power than ever before. Yesterday’s engine bearing load capacity no longer works today and tomorrow’s race engines will be even more powerful. There’s a need to meet these demands with higher bearing design standards and improved materials.
King Racing’s XP series of main bearings was developed to meet these challenges through technologically advanced geometrical features and a unique metal structure. Together, they drive the industry to a new level of durability and performance.

Powersports
Unique tailor made solution for powersports vehicle racing & cruising
Following in-depth research on performance powersports engine needs, King is proud to introduce the industry’s first high performance Powersports engine bearing line.
King’s Powersports line utilizes pMaxBlack™, a superior performance bearing structure and overlay, developed by King specifically for professional race teams in various demanding race platforms such as NASCAR, drift, drag, rally and more.
Smart design
King Powersports connecting main bearings are designed with tight, graded tolerances to preserve the exacting hydrodynamic regime required by high RPMs. They are available in thicker and thinner 5 grades
of STD to produce less or more clearance as well as 5 grades of 0.25mm to fit ground/resized crankshafts! These bearings are perfectly suited for both on-track competition and touring/cruising riders.
