. . .but there is no way in hell you'll be silent and sneaky. Sit in the forest for a while and listen to a quad running from miles away.
This ^ ^
When the wind is right, I can hear the kids at
the old dairy farm 3 miles a.t.c.f.
I've been riding various kinds and configurations
for many years, and can tell you that when you
don't dive too deep in the throttle, most all of
them are fairly quiet as delivered from the factory.
Let the machine do the work and let it putt putt
along and don't try to drive it like you're in a race
like 90% of everybody does. ( I'm as guilty as the
next guy)
