Imodoka itwara imodoka nigikoresho cyumutekano gikurura kandi kigabanya ingaruka ziva hanze kandi kirinda imbere ninyuma yumubiri wimodoka. Igikoresho gitanga umusego mugihe imodoka cyangwa umushoferi ahatirwa kugongana. Bamperi ya plastike igizwe nisahani yo hanze, ibikoresho byo kwisiga hamwe nigiti cyambukiranya. Isahani yo hanze n'ibikoresho bya bffer bikozwe muri plastiki, kandi urumuri rw'umusaraba rwashyizweho kashe y'urupapuro ruzengurutse ubukonje n'ubugari bwa 1.5mm kugira ngo rukore umwobo U; Isahani yo hanze hamwe nibikoresho bya buffer bifatanye kumurongo wambukiranya umusaraba, uhujwe nurwego rurerure rumuri rwimigozi kandi rushobora gukurwaho umwanya uwariwo wose. Plastiki ikoreshwa muri bamperi ya pulasitike muri rusange ikozwe mubikoresho bya polyester na polypropilene ukoresheje inshinge. Imashini yimodoka nigikoresho cyumutekano gikurura kandi kigabanya ingaruka ziva hanze kandi kirinda ibice byimbere ninyuma byumubiri wimodoka. Imyaka 20 irashize, ibyuma byimbere ninyuma byimodoka byari bikozwe mubikoresho byicyuma. Bashyizweho kashe mu cyuma cya U gifite uburebure bwa mm 3 zirenga. Ubuso bwari chrome yashizwemo, irazunguruka cyangwa irasudira hamwe n'ikibaho kirekire, kandi hariho icyuho kinini n'umubiri, wasaga nkibindi bintu. Hamwe niterambere ryinganda zimodoka, bumper yimodoka, nkigikoresho cyingenzi cyumutekano, nayo iri munzira yo guhanga udushya. Imodoka yumunsi imbere ninyuma ntishobora gukomeza umurimo wambere wo kurinda gusa, ahubwo ikurikirana ubwumvikane nubumwe hamwe nimiterere yumubiri, kandi ikurikirana uburemere bwabyo. Kugirango ugere kuriyi ntego, ibyuma byimbere ninyuma yimodoka bikozwe muri plastiki, bita plastike bumper. Amashanyarazi ya plastike agizwe nisahani yinyuma, ibikoresho byo kwisiga hamwe nigiti cyambukiranya. Isahani yo hanze n'ibikoresho bya bffer bikozwe muri plastiki, kandi urumuri rw'umusaraba rwashyizweho kashe y'urupapuro ruzengurutse ubukonje n'ubugari bwa 1.5mm kugira ngo rukore umwobo U; Isahani yo hanze hamwe nibikoresho bya buffer bifatanye kumurongo wambukiranya umusaraba, uhujwe nurwego rurerure rumuri rwimigozi kandi rushobora gukurwaho umwanya uwariwo wose. Plastike ikoreshwa muri bamperi ya pulasitike ikozwe mubikoresho bya polyester na polypropilene ukoresheje inshinge. Hariho kandi ubwoko bwa plastike bwitwa polyakarubone sisitemu mumahanga, yinjira mububiko bwa alloy kandi igakoresha uburyo bwo kubumba inshinge. Bumper yatunganijwe ntabwo ifite imbaraga zo gukomera gusa, ahubwo ifite ibyiza byo gusudira, ariko kandi ifite imikorere myiza yo gutwikira, kandi ikoreshwa cyane mumodoka. Amashanyarazi ya plastike afite imbaraga, gukomera no gushushanya. Urebye umutekano, irashobora kugira uruhare runini mugihe habaye impanuka yo kugongana no kurinda umubiri imbere ninyuma. Urebye uko bigaragara, birashobora guhuzwa hamwe numubiri hanyuma bigahinduka byose. Ifite imitako myiza kandi yabaye igice cyingenzi cyo gushushanya isura yimodoka.
