The single biggest reason to buy is its reformulated full synthetic chemistry that delivers markedly better friction and wear protection versus common industry and JASO standards, which translates to smoother shifting, reduced clutch slippage, and cleaner internals under varied riding conditions.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced full synthetic formula:\u003c\/strong\u003e Reformulated base stocks and additives maximize horsepower and acceleration while extending oil life compared with typical API SL oils.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior friction protection:\u003c\/strong\u003e Provides up to 10X better friction protection versus the JASO T9032016 friction standard to help prevent wet clutch slippage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced wear durability:\u003c\/strong\u003e Shows up to 5X better wear protection in IVA engine tests, helping extend engine life under high load and high temperature use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmission and clutch protection:\u003c\/strong\u003e Engineered to lubricate the gearbox and wet clutch with about 40% better transmission protection versus typical API SL quality oils for smoother shifting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeposit control:\u003c\/strong\u003e Improved resistance to sludge and deposits keeps oil passages clearer and helps maintain oil flow and engine cleanliness.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad OEM compatibility:\u003c\/strong\u003e Meets or exceeds API SL and JASO MA-2 standards for many Honda, Yamaha, Kawasaki and Suzuki 4-stroke motorcycles.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis oil suits hobbyists and daily riders who use 4-stroke motorcycles that require a heavier 20W-50 viscosity, including air-cooled V-Twins, older sport bikes, cruisers and off-road machines where thicker oil is preferred for protection.
