Ngo-2001 waqalisa kukhutshwa WR426F, kunye Yamaha WR450F - ngo-2003. Ngo-2007, bekukho isakhelo aluminiyam, kunye inaliti amafutha - ngo-2012, kodwa ngaphambi kokuba lo nyaka ibhayisekile iye yatshintsha kancinane. Oku akusayi kuchaphazela intengiso, kodwa emva kokuba ngokupheleleyo model ngonyaka 2016 kulindeleke kwakhona esitsholo ngokwenene. A loviwo ngokudlulisa kwezinye iinguqulelo ezinkulu, libe lingekatyhileki 6-phawundi ukwehla kobunzima, endaweni kwisisu semoto nokumiswa, tshintsha injini, ukuphuculwa gearbox kunye nenkqubo wayaphula.

chassis

Ngowe-2016, Yamaha yaqalisa isakhelo aluminiyam kabini emacaleni ukususela YZF, ukuba uba ngoko nangoko buqapheleke xa lihlala.

WR ukusuka ekuqaleni ukuya ekugqibeleni umntu uyilo elungeleleneyo kakhulu, isihlalo ukhululekile edityaniswe nokuphungulwa 5 mm kwaye libonelela footrest embindini indiza. Umahluko phakathi WR amanqwanqwa YZ yaye yenzelwe ukuba alungelelanise mva ukuya phezu ezimbi nokunyusa umgangatho ingxelo umqhubi. Kwakhona ubungakanani 2mm injini phambi ukunqunyanyiswa liye lancipha.

I Yamaha WR450F unayo kusini na inkqubo entsha Positioning-bar ezine, leyo zongeza ngokugqibeleleyo iphakheji ubuyekezo kwe SUV, njengoko kuvumela umqhubi ngokusesikweni ukugaleleka ngaphandle ngeendleko iintsimbi olongezelelweyo. Kuyenzeka ukuba alungise imeko kwi 26.5, 16.5 no-10 mm kwi umgangatho, nto leyo etshintsha ngokubaluleka ubungakanani-moya. Ngokutsho umsebenzisi ingxelo, nokwenza indlela yesithethe lokuqhuba isikhundla standard ingena ngokugqibeleleyo zombini osemendweni kunye ezimbi zomhlaba.

Ukongeza, ngesithuthuthu i Yamaha WR450F lixhotyiswe standard amavili-kwendlela yokulinganisa 18 no-21 intshi, ezinikwa kunye undi Excel omnyama, hayi isilivere njengangaphambili. Ezi emoto elungileyo Metzeler 6 Usuku Extreme, njengoko zanelisa iinkcukacha fim kunye ezinzima kakhulu.

iinguqulelo kancinane Terrain ziquka kubekwe kwicala-amanyathelo isakhelo, ifeni radiator, ngaphambili kunye nezibane angasemva. Forced zokupholisa kabi ngeemini ezishushu kunye namacandelo onzima cross-lizwe xa ngokwesiqhelo komoya akwanelanga.

ukumiswa

Kanye kwisisu semoto, ukunqunyanyiswa WR450F 2016 kusekelwe YZ450F. Kuzo zombini ngesithuthuthu phambi ifolokhwe isetyenziswa ne ukwahlulwa air-oyile KYB ne-22 mm ukubana kwe-114 mm umkhondo kunye 26,2 ° okuphosela engile, kodwa isetyenziswa WR elula isicwangciso yangaphakathi ukuba kangcono lokuqhuba off-endleleni.

A bayahlelwa efanayo wehlelwa ngasemva isithuthuthu, ezo isicelo emithonjeni KYB iinkcukacha YZF lithambile sentlalo enduro. sele Ezi ukuphuculwa ezincinane ngenxa WRF akwazi ukumelana nayo yonke imiba zokukhwela ngaphandle kwendlela, amacandelo zobugcisa kwendlela imigca-high speed.

Lilonke, xa kuthelekiswa imifuziselo ezidlulileyo, ibhayisekile entsha Yamaha WR450F yokuphatha iimpawu kunye lokuyimfihlo ngcono kakhulu.
