DID YOU KNOW?
– Did you know that when you buy a new motorcycle, at
least half of the bike’s components need some kind of
break-in procedure to perform at their best?
Brake pads, rotors, suspension seals, clutches, gears,
bearings, camshaft journals, your piston and piston ring,
and cylinder surface all work better when worked and
– Did you know that when most parts are manufactured,
they all have a rough surface to them, no matter how
microscopic, that is full of peaks and valleys?
– Did you know that “breaking in,” as a rule, is when
these two parts, with their rough surfaces, rub against
each other enough times, to rub the rough surfaces
smooth? This is what creates a nice-sealing, smooth-mov-
ing seal between the two parts.
–Did you know that in all cases of break-in that it’s
pressure and/or lubrication that makes the smoothing of
the surface and the break in possible?
– Did you know that the surface of a piston ring isn’t flat
but flattens out after correct break-in?
– And did you know that you can learn more about
break-in and proven break-in procedures at
