Complete piston for Polish mopeds Romet brand Alien
| Manufacturer: | Alien |
|---|---|
| Manufacturer id: | AE.T50-R5 |
- designed for Polish mopeds such as Komar, Romet, Ogar 205, Motorynka, Kadet
- the piston was made of high grade aluminum alloy with silicon content of 20%
- has a low coefficient of thermal expansion
- thanks to the anode coating, a lower coefficient of friction was obtained, which has a positive effect on the expansion of the piston
- microporosity of the coating improves the behavior of the oil film on the surface of the shell improving its lubrication
- higher surface hardness makes seizure more difficult
- the piston can be used both for connecting rods with needle bearing in the head as well as with original bearing on a bronze bushing
- shell geometry based on barrel profile, ovalised
- High quality surface finish and low bottom roughness minimize carbon build-up
- the rings have been made of the same type of cast iron as the factory piston rings, so the original resilience is retained
- the height of the ring groove has been reduced from the factory height of 2.50mm to 2.00mm for compatibility with commercially available rings for the Simson S51
- rectangular side lock changed to internal lock
- material selection in the pin hub is an important design element that reduces the volume of material in the area that expands most strongly during operation
- the piston hubs have been lengthened to work better with the needle bearing to ensure minimum cage movement, and to guarantee adequate lubrication
- equipped with additional lubrication holes in the piston pin hubs
- C-type piston pin protection, such as in modern motorcycles
- ALIEN piston with anodic coating
- 2.0mm high piston ring x 2 pcs.
- C-type piston protector x 2 pcs.
- 12mm piston pin
- instruction manual with values for fits and practical information on installation
