Bel-Ray Powersports announced a significant advancement of its 4-cycle engine oil portfolio, with more than 20 SKUs being reformulated across key product families including EXL, EXP, EXS, Thumper, and V-Twin. According to Bel-Ray’s official announcement and current product documentation, multiple updated products now meet or exceed API SP performance requirements and are qualified to JASO MA2, demonstrating the company’s continued focus on lubrication performance and consistency for modern four-stroke engines.
The reformulations are designed for high-load and high-RPM operating conditions. Advanced additive technology is used to enhance anti-wear protection, deposit control, oxidation stability, and engine durability. Bel-Ray’s current EXL, EXP, and EXS product pages identify API SP and JASO MA2 performance, while EXS uses a synthetic hydrocarbon and ester base-fluid formulation for high-performance four-stroke engines and wet clutches. Thumper Racing Synthetic Ester Blend 4T Engine Oil is also specified to meet API SP and JASO MA2 2023 requirements.
The updated formulations also address wet-clutch friction performance to support smooth and consistent engagement and shifting. Bel-Ray states that the portfolio upgrade is intended to meet the demands of today’s engines and riders across both recreational and high-performance powersports applications. The reformulation program therefore represents a substantial portfolio-level development, combining updated performance requirements with enhanced protection, cleanliness, durability, and clutch compatibility across the company’s four-cycle engine oil range.
