UMA RACING PERFORMANCE OIL
UMA Engine Oil Collection
High-performance synthetic engine oils engineered for smoother riding,
maximum engine protection, improved throttle response, and longer engine life.
Yamalube RS4GP is Yamaha’s flagship, high-performance fully synthetic engine oil, developed directly from their MotoGP racing technology. It is designed for riders who demand the absolute maximum from their machines, providing race-grade lubrication that excels under extreme high-RPM and high-temperature conditions.
Packaged in its iconic premium tin can, the RS4GP 10W-40 is the ultimate choice for the Yamaha R-Series (R1, R15, R3, R7) and MT-Series, though it is compatible with any high-performance 4-stroke motorcycle.
Key Features
-
MotoGP Heritage: Developed by Yamaha’s factory racing engineers to provide the same level of protection and power efficiency used on the world’s most demanding race tracks.
-
Advanced Full Synthetic Formula: Utilizes ultra-pure base oils that offer exceptional shear stability, ensuring the oil does not “thin out” even under punishing loads.
-
Maximum Power Transfer: Formulated to minimize internal engine friction, allowing the engine to rev faster and deliver more horsepower and torque to the rear wheel.
-
Superior Clutch Feel: Meets JASO MA2 standards, providing high-friction performance for wet clutches. It ensures precise gear shifts and eliminates clutch slippage during aggressive acceleration.
-
Ultimate Heat Management: Designed specifically to handle the intense heat generated by high-revving engines, preventing oxidation and maintaining a stable lubricating film.
-
Engine Longevity: Provides a “liquid armor” for critical components like the camshaft, cylinder walls, and transmission gears, significantly reducing wear compared to standard oils.

Why Choose Yamalube RS4GP?
-
The Gold Standard for Yamaha: This is the highest-spec oil Yamaha produces. If you own an R15 V3/V4, R3, or MT-15, this oil was literally built for your engine’s architecture.
-
Performance You Can Feel: Riders frequently report a smoother engine note, reduced vibrations at high RPMs, and a significantly “crisper” gearbox feel after switching to RS4GP.
-
Visual and Quality Assurance: The metal tin can is not just for aesthetics; it ensures the oil remains free from contamination and light degradation, preserving its chemical integrity until it reaches your engine.
Maintenance Tip
Since the RS4GP is a race-derived fully synthetic oil, it can handle longer drain intervals than mineral oils. However, for peak performance in street-ridden performance bikes, a change every 5,000 to 7,000 km is recommended. Always ensure you are using a genuine Yamaha oil filter to match the quality of this lubricant.
