Engine housing PX200/P200 - OEM base with spindled alternator side

No more playing the lottery with old housings: if cracks, worn bearing seats or damaged rotary valve surfaces put the brakes on a new build, a brand new engine housing is the clean solution. This version goes one step further: the alternator half is already spindled to fit crankshafts with a larger cheek circumference.

OEM look, modern reserves: The housing is made from new casting molds and comes with a clean, homogeneous surface. Critical areas are structurally reinforced without compromising the look.

Long stroke without milling stress: With many long-stroke crankshafts (e.g. Quattrini M244 stroke 60 mm), the alternator side is the bottleneck because the cheeks have a larger diameter. This housing is already machined there, making long-stroke setups up to 62 mm stroke much simpler and easier to plan. This saves time and reduces the risk of machining errors, especially for engines that need to reliably cover touring and everyday use.

Rotary valve base: The rotary valve sealing surface is large and cleanly machined, providing the basis for both close-to-production engines and powerful street setups.

The highlights in detail

Flawless base: brand-new casting from new molds - no more warped sealing surfaces or stripped threads.
Turned-out alternator side: prepared for crankshafts with larger cheek circumference, ideal for 60 mm long-stroke setups and up to 62 mm stroke.
Structurally reinforced: more material reserves in critical areas, including the auxiliary shaft area.
Tuning-friendly: sufficient material thickness at the transfer ports and a large rotary slide surface as a starting point.
Plug and play: Silent rubbers and stud bolts are already fitted.

Delivery condition

Motor housing (OEM rotary vane), prepared ready for installation
Silent rubbers already pressed in
All stud bolts already fitted
Without bearings (plan bearings and shaft seals separately)

Maximum flexibility: clean or fully removed

The housing is prepared, but can be installed cleanly and inconspicuously:

Without separate lubrication: Omit or decommission the oil pump and mix in the classic 1:50 ratio.
Without E Start: If you want to kick, close the opening in the fan duct with a suitable cover plate.
Downward compatible: depending on the model and peripherals, also suitable as a replacement for P200E or late Rally 200 (Ducati).

Technical information on the Sport version

State of construction: similar to Lusso generation, depending on the design, the internal shaft seal ring of the drive shaft can be used.
Oil pump and E Start: Axle and holes for oil pump as well as flange and bolt for starter motor are available.
Shaft seal seats: with wedge-shaped groove, suitable for rubber and metal shaft seals.
PX needle bearing: provided on the alternator side.
Lima side spindled: prepared for long-stroke crankshafts with larger cheek circumference (e.g. 60 mm) up to 62 mm stroke.
Cylinder base and housing: additional wall thicknesses in the cylinder mount and crankcase area for machining and stability.
Gasket set: suitable for assembly with standard gasket set.

Fits the following models (excerpt)

Vespa P200E / PX200 / PX200E (chassis prefix: VSX1T)
Vespa Rally 200 (chassis prefix: VSE1T)
Motovespa P200 DN (chassis prefix: 9DN)
Motovespa PX200 Iris (chassis prefix: 73C; with separate lubrication: 76C; E Start: 77C)
Motovespa TX200 (chassis prefix: 118C; E Start: 119C)

Note: When converting, always check the existing equipment status (ignition, covers, add-on parts). Depending on the model and year of manufacture, peripherals may need to be adapted.

Installation instructions

As the housing is supplied without bearings, include bearings and a revision set (seals and shaft seals) for the new assembly.
If E Start is to be used, a starter motor, bracket and the appropriate covers for the E Start version are also required.
Before reassembly: Clean and deburr the sealing surfaces and ensure clean grounding.

FAQ

The alternator half is already machined in the area of the crank webs. This means that long-stroke crankshafts with a larger cheek circumference (e.g. 60 mm setups) fit without this area having to be adjusted on the milling machine first.
Yes. Omit the oil pump or shut it down and mix in the classic 1:50 ratio.
No. The opening in the fan duct is closed with a cover plate, then the engine works normally as a kickstarter version.
