Isivivinyo: Yamaha YZ450F - ibhayisikili lokuqala "elihlakaniphile" le-motocross

Ngesizini ezayo ka-2018, i-Yamaha ilungiselele imodeli entsha ye-motocross engu-450cc. Bheka Manje isixhunywe ku-smartphone yakho, ongenza ngayo ngokwezifiso isithuthuthu ngendlela othanda ngayo. Ngaphansi komagazini we-Avto, i-YZ450F entsha ekhethekile ihlolwe e-Ottobia Open National Open Class ngu-Jan Oscar Katanec, owagijima i-Yamaha efanayo, kodwa ngo-2017, futhi wanikeza ukuqhathanisa okuqondile kokuqala.

Uhlelo olusha lwe-smartphone (i-IOS ne-Android) luvumela umgibeli ukuthi axhume esithuthuthu ngenethiwekhi engenantambo. Umshayeli angashintsha amaphethini enjini ngocingo, aqaphe i-rpm, izinga lokushisa lenjini ... Uhlelo lokusebenza lunikeza inothi lapho umshayeli ebhala khona lokho akufunayo emizila noma izimo ezithile. Kodwa akugcini lapho, ukumiswa okusha, uhlaka kanye ne-standard kagesi motor. Inhloko yesilinda yintsha futhi ilula, i-offset iphakeme ukuze uthole indawo engcono kakhulu yobuningi. I-piston nayo ithuthukisiwe, ama-radiator, asekhulile futhi afakwe ngendlela yokuthi umoya ugeleze kuwo ngokuqondile, kanye nesakhiwo.

U-Jan Oskar Catanetz: “Into entsha enkulu kunazo zonke edonsa amehlo ngokushesha, yiqiniso, isiqalisi sikagesi, engiphuthelwe ngempela njengomjaho wamamodeli adlule, ikakhulukazi lapho ngenza iphutha emjahweni futhi ngalahlekelwa amandla amaningi okuqalisa kabusha. umjaho. injini.

Engikuzwe kakhulu ukulethwa kwamandla okuhlukile enginomuzwa wokuthi kungcono kakhulu ngemodeli ka-2018 ngoba injini ayinalo udlame uma kunejubane eliphansi kodwa isinika amandla amaningi uma uyidinga ukuze ngichaze amandla enjini. imoto noma ukulethwa kwayo kuthethelela kakhulu uma kuqhathaniswa nonyaka odlule, nakuba imodeli ye-2018 ine "amahhashi" amaningi. Ukuphathwa kwebhayisikili kwangimangaza, ikakhulukazi emakhoneni lapho nganginomuzwa ongcono wokulinganisela nokulawula isondo lokuqala (i-fork offset yashintsha ukusuka ku-22 millimeters kuya ku-25 millimeters), kanye nokusheshisa, njengoba isondo elingemuva lihlala likhona. . kufanele kube. Yize amabhuleki eyafana kodwa i-suspension ishintshile kancane kunangonyaka odlule, ngiyizwe ibhalansi yebhayisikili njengoba i-centre of gravity igudluke kancane ibheke ngemuva ebhayisikilini uma kuqhathaniswa nohlobo lwangonyaka odlule. Kodwa ngiphinde ngaba nethuba lokuzama ibhayisikili i-WR450F (enduro), futhi into yokuqala engiyiqaphelile kwakuwukukhanya kwebhayisikili, nakuba isisindo sayo singamakhilogremu angu-11 ngaphezu komlingani walo we-motocross.

Kwakuyilokhu kukhanya okwanginika umuzwa wokuphepha nokuphila kahle lapho ngingena emakhoneni, futhi ukumiswa kwenze umsebenzi oncomekayo kuma-bumps, kodwa kwakuthambile kakhulu ukuthi ngingagxumela ohlangothini oluyisicaba lwethrekhi. Njengoba kufanele ibhayisikili le-enduro, amandla enjini ayephansi impela, ngakho-ke kwakudingeka ngishayele ngamandla kulayini we-motocross. Ngamangala kakhulu ukuthi ngakwazi kanjani ukugibela leli bhayisikili le-enduro emzileni ogcwele amaqhubu, iziteshi ezijulile kanye nokugxuma okude. "
