So long as it is synthetic and motorcycle specific you shouldn't have any issues. Everyone has their favourite brands and swears by them. Some oils are better than others but because most people change the oil way before it is due, you should never have a problem with viscosity breakdown or additive issues. I like Mobil 1 4T, Amzoil and have even used synthetic Shell Rotella T6 diesel oil which meets the Triumph spec requirement by the way.
Change the oil and ride.
