We use lucas in all of our vehicles, and when i bought a new '13 crf250r i did lots of research on what oil will take care of the motor best and all the evidence i found pointed me here. I have not had any issues
Lucas High Performance 4T Motorcycle Oil with Moly is designed for non-wet clutch applications. The unique moly chemistry provides maximum friction reducing properties in severe racing applications and is the result of technology gained through years of blending motor oils and gear oils for the racing industry.
Use in all air-cooled and water-cooled 4-stroke engines; these are true racing oils that far exceed all manufacturer specifications and can outlast other oils up to 4 times on the track or on the street.
