Aprilia rs125 Warming up
1) After engine start up, engine speeds of 6000 rpm to 7000 rpm will
be kept with constant throttle opening until coolant temperatures go up to 40°C to 50°C.
2) If coolant temperatures reach the specified level above, then the
throttle is gradually opened until 10000 rpm is attained. After that,
snapping is used to keep warming up and the fuel cock is turned off
when coolant temperatures reach 55°C. If coolant temperatures reach
60°C to 65°C or you feel sharp engine revving up, warming up has
been completed.
3) To stop the engine, fully close the throttle. Do not turn off the kill
switch while throttle is kept open.

Running in plays an important play in determining your physical
conditions or avoiding mechanical failures. New machine or those
with some parts replaced with new ones must be run in.

1) • for running in mileage, see owners' manual.
• Coolant temperatures: about 55°C
• Carburetor setting should not change from the best settings (lean
setting must not be acceptable)
2) • Running at as higher gears (5th or 6th) as possible using fully
open throttles is the best. If engine speeds are going up beyond the
set speed, full opening or closing of the throttle is used to control the
engine speed.
• Engine speed associated with down shifting should not be raised so
higher. (engine braking rpm associated with down shifting should be
gradually raised as well)
3) • To stop the engine, fully close the throttle. Do not turn off the
kill switch while throttle is kept open.
The reasons why running in is required

The reasons why running in is required
Running in means the work which makes moving parts to move
smoothly without resistance. Running in must result in smoothness
instead of looseness. Smoothness without looseness means that parts
are able to move to intended positions accurately, speedily without
any resistance, resulting in, when parts are assembled, the best
performance.
Good running in practice will give parts prolonged life, providing
constant performance for extended period of time.
For instance, if loads are applied to pistons at a stretch at the initial
stage of running in, deformed pistons will result, which will reduce
service life of the cylinder as well since already deformed pistons
cause severe contacts partially at the extended travel kilometres.
Also, the performance will be degraded as well.
Good running in practices will secure constant performance for
