The high-quality 38 mm (50 cc) racing cylinder kit is now also available exclusively with «Vertex» pistons.
Fits Puch Maxi, X30 Sport NS/NL, X30 Sport NG-2A and Supermaxi.
Vertex pistons are world-renowned for their quality and design.
In terms of appearance, this racing cylinder is indistinguishable from the original. The cast-in «CH12» and original-sized cooling fins ensure optimum protection from the race control.
Exhaustive instructions for correct installation and running-in are included.
This racing kit should preferably be used with a 22 mm exhaust (2-bend) or 22 mm manifold so that the exhaust gases can also be removed and no heat build-up occurs.
&p>Revised version: The sealing surfaces of the inlet and outlet have been enlarged so that a large 28 mm flame tube can also be fitted without any problems. There is also no more piston protrusion and the cylinder has been adapted accordingly. Last but not least, the inlet gasket has also been reworked.
Nostalgic product for the highest demands of the quality brand swiing®.
