SHIFTING
The housing uses the 1-pull shifting technology of the XL2 models

Here, a rigid shift wire is used to link the shift gate. The attachment of the shift cable differs from that of the Italian models (the mounting hole is larger). If the engine is to be controlled with two shift cables (as on XL1, PV, V50 etc.), a conversion kit is available for this purpose (see Accessories for both).

The SE125 engine block already uses the modern shift components of the XL2 models internally. The shift arm no longer has a parallelogram. It is guided in a continuous bearing track, supported by a needle bearing and sealed by a shaft seal. For this reason, only XL2 gearshift components fit into the SE motor housing:

XL2 shift arm + screw

- cable mount

- shift arm shaft seal

- shift arm bearing

These components are always required if no XL2 donor motor is available

PERFORMANCE
The SE125 housings have a long rotary valve sealing surface (42mm). This allows the intake to be greatly enlarged, making them ideal for high-performance tuning on a rotary valve basis.

CYLINDER
The cylinder base bore is 61.5mm, making it suitable for all standard and common tuning cylinders (not Falc, Quattrini SP09 etc.). It does not need to be spindled.

INTAKE B

The intake manifold has a 3-hole mounting system, so the V50, PV125 manifolds do not fit here.

SCOPE OF DELIVERY
The housing is supplied without bearings, nuts or cylinder studs, but with all silent blocks/silent rubbers
