It is commonly thought that warming up a motorcycle is necessary to
prevent accidental stalling (and dumping the bike if it happens at low
speed). However, with fuel injection (standard on H-D now for more than
half a decade) and automatic enrichment circuits, this is not necessary. [1]
And a stock H-D idling to warm up is not too bad - the problems is these
wannabee badasses gut their mufflers or put on illegal pipes that are
not EPA certified to meet the noise emissions standards [2], then sit
and cause excessive internal wear by revving their engines excessively
while still cold.

I will pass bicycles in the same lane, as I am less than 3 feet wide at
the mirrors/elbows, and can tell how much clearance I have much more
precisely than if I was in a cage. I do slow down so I am not going
much faster than they are (as hitting a person on a bicycle would like
put both of us down) and use relative low engine speed and throttle to
pull away (except on the 108cc scooter, which is not going to produce a
loud scary exhaust note (or much acceleration for that matter) at full
throttle).

J. Brandt reported that his tests for Avocet indicated that a smooth
tread, normal compound bicycle tire would lose grip at about 45° of lean
angle. Modern sport-bike tires will slip at about 40° of lean on clean,
*wet* pavement, and at about 60° on clean, dry pavement (once warmed
up). However, most sport-bikes will start dragging pegs at a bit less
than 50°, so as to prevent high-side falls that may launch the rider
into the air and/or into oncoming traffic, which why hanging off the
bike is used to increase cornering speeds. Contrast that to most H-D
cruisers running out of ground clearance at 26° to 32° of lean (per the
H-D website), and many H-D riders being the types with 6 months of
riding experience many times over, so they do not hang off the bike, and
you will understand why their cornering speeds are so slow (along with
cruiser tires being significantly harder/less grippy than sport-bike and
sport-touring tires).
[1] Main problem is making large carbureted engines meet emissions
standards, which requires excessively lean running.

dBA limit is measured at 50 feet perpendicular to the longitudinal axis
of the bike (the other common measurement is 12 inches from the exhaust
outlet, which typically produces numbers from 80 dBA at idle for quieter
stock bikes, to in excess of 110 dBA for some non-certified systems at
full throttle.
