ULTRA 1PLUS 4T 20W-50 Full Synthetic Motorcycle Oil, 6-Quart – JASO MA2, API SN Protection

ULTRA 1PLUS 4T 20W-50 is a full synthetic motorcycle engine and transmission oil formulated to protect high-RPM 4-stroke bikes while maintaining wet-clutch performance.

Designed for street bikes, cruisers, sport bikes and motorsport applications, this 20W-50 full synthetic oil meets API SN and JASO MA2 specifications to balance engine protection with reliable clutch engagement. Its formulation focuses on wear reduction, high-temperature stability and gearbox protection for motorcycles that operate under heavy load, high RPMs or varied seasonal conditions.

How does this oil protect my engine during high-rpm and racing conditions?

The full synthetic base and additive package form a durable lubricating film that resists breakdown at sustained high temperatures and engine speeds. That film minimizes metal-to-metal contact during start-up and prolonged high-RPM operation, helping reduce component wear and maintaining performance across demanding rides.

• High viscosity 20W-50 protects against thinning at elevated temperatures
• Full synthetic base resists thermal and oxidative degradation
• Anti-wear additives reduce friction and gear surface damage
• Cleaner formulation helps limit sludge and varnish buildup

Will this oil work with my motorcycle’s wet clutch and gearbox?

Yes — ULTRA 1PLUS 4T 20W-50 is JASO MA2 certified to preserve proper wet-clutch friction characteristics and smooth shifting in integrated transmission systems. The formula is engineered to prevent clutch slippage while protecting gears under high load, making it suitable for bikes with combined engine and gearbox lubrication.

• JASO MA2 rating ensures stable clutch engagement
• Formulated for motorcycles with integral gearboxes
• Helps maintain smooth shifts under load
• Reduces gear wear in severe applications

What riding conditions and bike types is 20W-50 best suited for?

This multi-grade 20W-50 synthetic oil excels in warmer climates, high-load touring, aggressive sport riding and motorsport scenarios where higher operating temperatures are common. It is a flexible choice for street bikes, cruisers, sport bikes and off-road machines that require thicker protection at operating temperature.

• Ideal for warm-weather and high-temperature environments
• Recommended for high-load touring and racing use
• Compatible with a wide range of 4-stroke motorcycles
• Suitable for bikes needing extra film strength at operating temps

How does this oil help keep the engine clean and extend component life?

The blend includes detergents and dispersants that reduce sludge, varnish and deposit formation, helping keep internal parts cleaner over time. Cleaner surfaces and stable lubrication contribute to longer service life for bearings, camshafts and transmission gears when used within recommended change intervals.

• Detergent additives reduce deposit buildup
• Dispersants keep contaminants suspended for easier filtration
• Reduced sludge improves oil flow and cooling efficiency
• Protects bearings and cams against wear

Who is this for: ULTRA 1PLUS 4T 20W-50 Full Synthetic is aimed at riders who demand robust, high-temperature protection from a single oil — racers, sport riders, long-distance touring motorcyclists and owners of cruisers or bikes operated in warm climates. If your motorcycle requires API SN and JASO MA2 compliance and you frequently ride at high RPMs or under heavy loads, this oil provides the combined engine, clutch and gearbox performance you need. For cold-start protection in very cold climates or bikes specifying a lighter viscosity, consult your owner’s manual for the recommended alternative.
