Bel-Ray EXS Synthetic Superbike Motor Oil is a fully synthetic multi-grade 4-stroke engine oil specifically formulated for high performance superbike engines utilizing a wet clutch. The critical performance properties of Bel-Ray EXS Synthetic, shear-, oxidation- and viscosity stability, film strength and high Viscosity Index, are only attainable with synthetic products. Bel-Ray EXS Synthetic is the most effective product for premium lubrication performance and engine protection.

Applications

• For best performance and protection at high loads and rpm typical of racing and sport riding.
• Use in all high output/high rpm 4-stroke engines, including turbo- and super-charged engines.
• Equally suitable for air-cooled and liquid-cooled engines.
• Use when maximum power and minimum friction are required.
  

Features and Benefits

• Superior anti-wear - Longer engine service life and longer bearing life. Reduced cylinder- and ring wear for long term performance reliability.
• Superior deposit control - Cleans existing deposits. Reduces sludge and varnishes for cleaner and cooler running engines.
• Wide viscosity grade range - Reliable high and low temperature performance for easy cold starts and maximum high temperature protection.
• Fully synthetic base oil - Minimizes friction for maximum power. Wet clutch formulation allows smooth and consistent clutch performance.
• Superior viscosity stability - Unsurpassed shear and oxidation stability. Low volatility base oils eliminate viscosity breakdown and formation of sludge and deposits for longer drain intervals and low oil consumption.
• Low coefficient of friction - Maximum power and superior fuel economy.

General Description

Bel-Ray EXS Synthetic Superbike Motor Oil is specifically formulated with fully synthetic base oils for high performance 4-stroke motorcycle engines for the best engine performance and protection. Unique anti-wear additives reduce valve-train wear, piston- and ring scuffing and bearing wear. Bel-Ray EXS Synthetic is designed for the very high loads and shear stability requirements of gear boxes and clutches for smooth and efficient power transfers.

Special Instructions

Due to anti-wear characteristics of Bel-Ray EXS Synthetic Superbike Motor Oil, a standard petroleum motor oil must be used on new engines during the engine break-in period (between 600-800 miles)
