Imiterere
Isahani yo hanze n'ibikoresho byo mu bwoko bwa bffer bikozwe muri plastiki, kandi urumuri rw'umusaraba rwashyizweho kashe mu gikingi cya U gifite urupapuro ruzengurutse ubukonje rufite uburebure bwa 1.5mm; Isahani yo hanze hamwe nibikoresho bya buffer bifatanye kumurongo wambukiranya umusaraba, uhujwe nurwego rurerure rumuri rwimigozi kandi rushobora gukurwaho umwanya uwariwo wose.

Bumper yatunganijwe ntabwo ifite imbaraga zo gukomera gusa, ahubwo ifite ibyiza byo gusudira, ariko kandi ifite imikorere myiza yo gutwikira, kandi ikoreshwa cyane mumodoka.
Uburinganire bwa geometrike ntibushobora gusa guhuza imiterere yikinyabiziga cyose kugirango habeho ubwiza, ahubwo bugomba no kubahiriza imiterere yubukanishi hamwe n’ibiranga ingufu kugira ngo habeho kwinyeganyeza no kuryama mu gihe cy’ingaruka.
