 WARNING
Always wear safety glasses and gloves. Pay particular attention
to your fingers while working with the motorcycle chain and sprockets. |
|
Consult the "Products" section
to select a chain according to the style, vehicle displacement and
type of riding.
Don’t change the vehicle’s original chain size, both in its dimensions
or characteristics. |
| Inspection and replacement of the sprockets |
Frequently check the wear on
the front and rear sprocket teeth. Examine both the tooth profile and the
thickness. These components must be replaced if there are missing or broken
teeth, or if they show noticeable wear or other damage.

WARNING
A new chain, if assembled on worn or damaged sprockets, will
deteriorate quickly.Therefore, as a general rule, always replace both front
and rear sprocket when replacing the chain. This ensures the proper uniformity
of the whole transmission system. |
|
Both sprockets must be chosen in accordance to the dimensions of
the original ones.
When selecting a replacement front sprocket, always choose
a heat treated type.
For high power motorcycles, it is recommended to use heat treated
rear sprockets (with induction hardened teeth) which offer excellent resistance
against wear.
When assembling, it is strongly recommended to replace worn or damaged
bolts, nuts and washers. Once they have been installed, make sure that the
sprockets do not have any eccentricity or wobbling while rotating.
Check the alignment between front and rear sprockets by using a straight
edge or bar of sufficient length (min. 1 m - 3.3 feet) and continue
as follows:
1 Place the bar on the side
of the rear sprocket as near as possible to the rotation centre in order to
obtain the longest bearing surface.
2 Check that the front sprocket
is aligned to the rear as shown by the straight edge. Adjust the
alignment to within 1mm (.04") by using the tensioning screws or
shims, without compromising the alignment of the motorcycle wheels. |
