Igiciro cyumvikana 16 santimetero Umuyoboro udafite ibyuma SCH40
Ubu dufite imashini zihanitse. Ibisubizo byacu byoherezwa muri Amerika, Ubwongereza nibindi, twishimira izina hagati yabaguzi ku giciro cyiza 16 santimetero y'icyuma kitagira ibyuma SCH40, Ubu twashyizeho imikoranire mito kandi miremire mito mito hamwe n’abaguzi baturuka muri Amerika ya Ruguru, Uburayi bw’iburengerazuba. , Afurika, Amerika y'Epfo, ibihugu n'uturere birenga 60.
Ubu dufite imashini zihanitse. Ibisubizo byacu byoherezwa muri Amerika, Ubwongereza nibindi, twishimira izina hagati yabaguzi, Turibanda mugutanga serivise kubakiriya bacu nkikintu cyingenzi mugushimangira umubano wigihe kirekire. Guhora tubona ibisubizo byo murwego rwohejuru duhujwe na serivise nziza yo kugurisha mbere na nyuma yo kugurisha bituma irushanwa rikomeye ku isoko rigenda ryiyongera ku isi.
