Product Overview & Specifications
Motorex Race Power 4T 10W-50 is an ultra-high-performance, fully synthetic motor oil meticulously engineered for demanding 4-stroke motorcycle engines. Leveraging a sophisticated blend of Group IV Polyalphaolefin (PAO) and Group V Ester base stocks, complemented by an advanced, robust additive package, this lubricant is designed to provide exceptional protection and performance under the most extreme operating conditions, characteristic of racing and high-performance street applications. Its formulation prioritizes thermal stability, shear resistance, and optimal wet clutch compatibility, critical attributes for integrated engine, clutch, and gearbox lubrication systems prevalent in modern motorcycles. The “Race Power” designation directly reflects its intent to deliver maximum power output and reliability in high-revving, high-temperature environments, making it a preferred choice for sportbikes, superbikes, and track-oriented motorcycles.

Recommended Applications & Car Compatibility
Motorex Race Power 4T 10W-50 is primarily formulated for high-performance 4-stroke motorcycle engines that share a common oil sump for the engine, wet clutch, and gearbox. Its robust 10W-50 viscosity profile makes it exceptionally suitable for:
- High-revving sportbikes, superbikes, and naked bikes from manufacturers such as KTM, Husqvarna, Ducati, Aprilia, BMW Motorrad, Yamaha, Honda, Kawasaki, and Suzuki.
- Engines operating under severe conditions, including sustained high RPMs, extreme ambient temperatures, and competitive racing or track day usage.
- Motorcycles equipped with wet multi-plate clutches, where the JASO MA2 specification guarantees optimal friction characteristics, preventing clutch slip and ensuring smooth, consistent power transfer.
- Both liquid-cooled and air/oil-cooled engines, where the high thermal stability and robust film strength of the 50-grade provide superior protection against heat-induced degradation and wear.
- Engines requiring enhanced gearbox protection, as its shear-stable formulation protects gear teeth from pitting and wear under high loads.
This oil is specifically designed for motorcycle applications and should not be used in automotive engines unless explicitly recommended by the vehicle manufacturer for very specific, often vintage or highly modified, circumstances.
Operating Conditions & Drain Intervals
- Standard Drain Interval: For normal street riding and highway usage, it is recommended to adhere strictly to the motorcycle manufacturer’s specified oil change interval, typically ranging from 6,000 to 12,000 kilometers (approx. 3,700 to 7,500 miles) or annually, whichever comes first. The synthetic base stocks and additive package are designed to maintain their integrity over these periods under standard operating conditions.
- Severe Service Interval: Under severe operating conditions such as continuous heavy city traffic with frequent stop-and-go cycles, aggressive sport riding, track days, competitive racing, or sustained high-temperature operation, the drain interval should be significantly reduced. For racing or intensive track use, it is common practice to change the oil every 1,000 to 3,000 kilometers (approx. 600 to 1,800 miles) or after every few track events, depending on the intensity and engine load. This ensures maximum protection against wear and prevents lubricant degradation under extreme thermal and mechanical stresses.
- Temperature Performance: The 10W designation provides excellent cold-start performance, ensuring rapid oil circulation and protection of critical engine components even at sub-zero temperatures, minimizing start-up wear. The 50-grade hot viscosity offers exceptional film strength and resistance to thermal breakdown at elevated operating temperatures, common in high-performance motorcycle engines, particularly during sustained high-speed riding or track sessions. Its robust formulation prevents viscosity shear and maintains critical lubrication properties even when engine temperatures soar, safeguarding against wear and oxidation.
Usage Restrictions & Limitations
While Motorex Race Power 4T 10W-50 offers superior performance for its intended applications, it is crucial to observe specific restrictions and limitations to prevent potential engine damage or suboptimal operation:
- Two-Stroke Engines: This oil is strictly formulated for 4-stroke engines and is absolutely unsuitable for 2-stroke engines, which require a completely different lubricant chemistry designed for combustion with fuel. Using Race Power 4T in a 2-stroke engine will lead to severe engine damage.
- Incompatible Viscosity Requirements: Do not use this oil in engines that specifically require a different SAE viscosity grade (e.g., 5W-40, 15W-40, 20W-50) unless the motorcycle manufacturer explicitly permits or recommends a 10W-50 oil. Mismatched viscosity can lead to inadequate lubrication, increased parasitic losses, or potential damage to engine components, especially in engines with very tight tolerances or specific hydraulic valvetrain requirements.
- Automotive Applications: This lubricant is specifically designed for motorcycle engines, particularly those with integrated wet clutches. Its additive package, including friction modifiers specific to JASO MA2, is generally not optimized for automotive engines and could potentially impact catalytic converter efficiency or lead to other issues if used outside its intended scope.
- Older Engine Seal Compatibility: While highly unlikely with modern synthetic formulations, some extremely old motorcycle engines (pre-1980s) originally designed for mineral oils might experience seal compatibility issues with certain synthetic esters, potentially leading to leaks. Always consult the OEM recommendations for vintage engines.
- Low-Ash Requirements: This oil is not formulated to meet specific low-ash (SAPS) requirements typically found in some modern diesel automotive engines with Diesel Particulate Filters (DPFs). Such considerations are irrelevant for motorcycles, but it’s a critical distinction if one were to erroneously consider it for non-motorcycle applications.
