5.2.9.7.1 Update specifications
The FIM can grant a parts and product update differing from above
rule, purely for the scope of production cost saving provided that
following provisions are kept:
- Crankcase is not lighter* than the original homologated unit and the
positions of crankshaft, gearbox, frame attachments, main shafts and
position of cylinders remains unchanged (*apart casting method for
mass production).
- Cylinder(s) have same inner geometrical dimensions including sleeve
and are no lighter than the original unit.
- Cylinder head: combustion chamber shape and volume, valve and
camshaft locations as well as intake and exhaust ports locations and
shape remain unchanged.
- Crankshaft: same stroke and not lighter than original homologated
unit.
- Connecting rods: same base material (i.e. steel) and not lighter then
original homologated unit.
If more than 2 items of the above need to be updated during the
machine’s life, a new homologation will be necessary.
