Pakadali pano, bolodi la PP loletsa moto lakhala likugwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, kupanga makina, kupanga zida zamagetsi, kupanga magalimoto, migodi, uinjiniya wolumikizirana, kumanga magetsi ndi zina.

Lawi la PP bolodi lawi ...
Pakadali pano, pali njira zambiri zowunikira kuchedwa kwa moto, monga kudziwa kuchuluka kwa mpweya, kuyesa kuyaka mopingasa kapena moyimirira, ndi zina zotero. Mlingo wa mapulasitiki oletsa kuyaka umawonjezeka pang'onopang'ono kuchokera ku HB, V-2, V-1 mpaka V-0:
1, HB: kalasi yotsika kwambiri yoletsa moto mu muyezo wa UL94. Imafuna liwiro loyaka losakwana 40 mm pamphindi pa zitsanzo za makulidwe a 3 mpaka 13 mm; Pa zitsanzo za makulidwe osakwana 3 mm, liwiro loyaka losakwana 70 mm pamphindi; Kapena tulukani pa chizindikiro cha 100mm.
2, V-2: Pambuyo pa mayeso awiri oyatsa kwa masekondi 10 pa chitsanzo, lawilo lidzazimitsidwa mkati mwa masekondi 60. Mutha kugwetsa kuyatsa.
3, V-1: Pambuyo pa mayeso awiri oyatsa moto a masekondi 10 pa chitsanzocho, lawilo lidzazimitsidwa mkati mwa masekondi 60. Palibe chinthu choyaka chomwe chingagwe.
4, V-0: pambuyo pa mayeso awiri oyatsa moto a masekondi 10 pa chitsanzocho, lawilo lidzazimitsidwa mkati mwa masekondi 30. Palibe chinthu choyaka chomwe chingagwe.
