Running In; Brakes - BMW C 400 X Rider's Manual

Running in

Engine
Before the break-in service,
ride with frequently changing
load ranges.
Try to do most of your rid-
ing during this initial period on
twisting, fairly hilly roads, avoid-
ing highways if possible.
Have the break-in service per-
formed after 300 – 750 mi
(500 – 1200 km).
Brake pads
New brake pads must be run in
before they achieve their opti-
mum friction force. This initial
reduction in braking efficiency
can be compensated for by ex-
erting greater pressure on the
brake levers.

Extension of the braking distance,
accident hazard
Brake early.
Tires
New tires have a smooth sur-
face. This must be roughened by
riding in a restrained manner at
various lean angles until the tires
are run in. This running in proce-
dure is essential if the tires are to
achieve maximum grip.
WARNING
Loss of adhesion of new tires
on wet roads and at extreme
angles
Accident hazard
Always think well ahead and
avoid extreme angles.

Brakes

How do you achieve
the shortest stopping
distances?
The dynamic load distribution be-
tween the front and rear wheel
changes during braking. The
heavier you brake, the greater
the weight transfer to the front
wheel. Increases in the load on
an individual wheel are accom-
panied by a rise in the effective
braking force that the wheel can
provide.
To achieve the shortest possi-
ble braking distance, the front
brake must be applied quickly
and with progressively greater
levels of force. This procedure
provides ideal exploitation of
the extra weight transfer to the
front wheel. With the frequently
instructed "forced braking," in
which the brake pressure is gen-
erated as quickly as possible and
