Cylinder -PARMAKIT TSV09 Red Devil 177 ccm 3 port, 57mm stroke, 2-piece exhaust, 2-piece cylinder head, screw flange- Vespa PX125, PX150, Cosa125, Cosa150, LML Star 125/150, Stella 125/150

PARMAKIT TSV09 Red Devil 177cc cylinder for Vespa PX and LML

Cleanly processed aluminum cylinder with Nikasil coating from Scauri for Parmakit. Comes with a very high-quality VERTEX piston (Ø=63 mm) with two 1 mm thin steel rings and a solid CNC head (exception TSV ECV = cast head) with centering in the bore. All cylinder variants have the same overflow layout with four generously dimensioned main transfer ports and a boost port.

Parmakit has differentiated between the following versions since 2019:

• TSV ECV Classic = 1 oval exhaust window, one-piece cast cylinder head
• TSV09 'Puffo' = 3 outlet windows (main + two secondary outlets), one-piece CNC cylinder head (blue)
• TSV09 'Red Devil' = 2 exhaust windows (large exhaust with bar), two-piece cylinder head (red), screw flange
• TSV66 = Bigbore, cylinder bore of 66 mm (195 / 205cc), housing must be spindled on

CYLINDER VERSIONS

Depending on the version selected, the cylinders differ in their exhaust design.

The TSV ESC with its conventional exhaust and simple cast iron cylinder head is ideal for anyone who wants to create a proper engine with little effort.

The 'Puffo' version (Italian = Smurf) has two additional exhaust windows, making the cylinder ideal for use with a sports exhaust system. It offers more potential than the ECV due to the enlarged exhaust area, but subsequent exhaust machining is more complex due to the two small secondary outlets. The CNC-machined solid aluminum cylinder head offers more reserves and better temperature stability than the cast head of the ECV cylinder.

With its large, two-part exhaust window, the Red Devil has the greatest performance potential and also offers the best possibilities for subsequent modification of the exhaust port with its bolted-on exhaust flange. The two-part head with separate internal dome allows the combustion chamber to be easily modified to your own specifications.

The large surfaces and moderate timing of the cylinders make them ideal as powerful tourers. With the right exhaust system, outputs of around 17-20 hp are possible without further processing. With increased timing angles and further cylinder machining (exhaust), the cylinder can also develop significantly more power.

• Bore Ø: 63 mm
• Stroke: 57 mm
• Displacement: 177.59cc
• Cast iron piston
• Weight: 185gr (without pins and rings)
• Piston ring: 2 pieces, 1.0 mm steel
• Piston dimension: 62.92 mm
• Compression ratio: 11.3:1
• Distance sealing surface to crushing surface: +2.30 mm
• Recommended crushing edge: 1.6-1.7 mm

SCOPE OF DELIVERY
The scope of delivery includes six base gaskets and five head gaskets, each 0.2 mm thick, for adjusting the control angle and the pinch edge. This makes it possible to use a crankshaft with a 60 mm stroke and adjust the cylinder to the longer stroke accordingly. The increased timing angles result in a wider speed range and higher torque/power. For touring engines, however, a crankshaft with 57 mm stroke is perfectly adequate and usually makes more sense in everyday use.

CONCLUSION: Reliable cylinder for long tours at high cruising speeds!
