There is no such thing as standard motorcycle gear oil, and if your bike is shaft drive, you're going to need the protection of a limited slip gear oil.
Motorcycle gear oil page
Whether your motorcycle has a two-stroke or four-stroke engine, getting the gearbox oil right is essential. Your bike probably has a wet clutch, in which case it shares your motorcycle’s engine oil.
However, if you’re riding a shaft-drive motorcycle, you’re going to need limited slip gear oil too, providing the durability and protection of a full synthetic formulation created by liquid engineering.
Castrol AP Gear lubricants are multi-purpose, extreme pressure gear oils that are thermally stable and will provide transmission, differential and other application protection beyond that specified for SAE J2360 (Formerly MIL-PRF-2105E) requirements. This thermal stability extends oil service life and reduces critical component
wear. They are recommended for make-up and complete refill of most passenger
car and light truck conventional differentials, transmission and steering
gears.
