edit: n/m i'm dumb

it refers to the maximum amount of pulling (horsepower) and twisting
power (torque) that your engine in making, and at how many revolutions
per minute (RPM) it is making it.
metric is a little different and i don't know the coversion BUT
basically
power=how much energy is being tranferred over a given time period
i don't know metric, but in industrial measurement this is enough
energy to move 550 pounds one foot in one second
torque=twisting force generated by the engine
torque is a hell of a lot more complicated, in any language.  you need
formulas and an understanding of angular velocity and whatall
which i don't have, i just know that it's twisting force
RPM=revolutions per minute, how fast the engine is turning when the
machine recorded the maximum numbers

torque gets you off the line
power gets you haulin' a.s

hope that was mildly helpful.

The specific numbers seem to indicate that you are maybe looking at
something on the small end of "karts" (since the numbers are small and
the RPMs high)?   See for instance

A primer on what the numbers *mean*:

make engine-building decisions) and the driving (when to use which
gears based on speed and on what you're going to do next) aspects of
how to win, both of which are the subject of chapters if not books,
and on which my understanding is too inexpert to do more than refer
you to them...
