Engine warm up on this “new” bike is no more than 30 seconds to a minute.
Oil specs cover cold and warm engine AND environmental conditions. Hence the 15W-50 rating. For example:
“OK . . .What does a 5W-30 do that an SAE 30 won't?
When you see a W on a viscosity rating it means that this oil viscosity has been tested at a Colder temperature. The numbers without the W are all tested at 210° F or 100° C which is considered an approximation of engine operating temperature. In other words, a SAE 30 motor oil is the same viscosity as a 10w-30 or 5W-30 at 210° (100° C). The difference is when the viscosity is tested at a much colder temperature. For example, a 5W-30 motor oil performs like a SAE 5 motor oil would perform at the cold temperature specified, but still has the SAE 30 viscosity at 210° F (100° C) which is engine operating temperature. This allows the engine to get quick oil flow when it is started cold verses dry running until lubricant either warms up sufficiently or is finally forced through the engine oil system. The advantages of a low W viscosity number is obvious. The quicker the oil flows cold, the less dry running. Less dry running means much less engine wear.”
Do not worry about the engine after 30 seconds to a minute - at ANY speed or rpm. The 2018 technology of oil has you covered.
Worry about the other factors of starting a ride: your attention, your muscle memory of clutch, brake, throttle, road conditions, and “threats”, and your COLD tires...
