Ngemva konyaka, lapho Model 2016, kwakubonakala sengathi WR450F kungaqashelwa futhi. Lokho kwaba ngaphambi Australian Moto GP maphakathi no-Okthoba 2015, lapho le nkampani yabonisa imodeli ethuthukisiwe ngokugcwele.

Yamaha WR450F: Sibutsetelo izinguquko

Umklamo we WR sokugcina sidalwe nge iqhaza nabagibeli abaningi, ikakhulukazi wangaphambili party MXGP Josh Coppins. Umshini omusha isekelwe injini, chassis, ukumiswa, ukudluliswa kanye wazihlephula uhlelo, World Cup winner YZ450F, okuyinto ngqo nomthelela ekunciphiseni isisindo isithuthuthu, ukwandisa umthamo wayo futhi sithuthukise ukuzinza.

Ngemva wamavukelambuso imodeli umugqa WR lokuqala, eyabonakala ngaphansi kwesihloko esithi Ngo-1998 WR400F, kukhona uchungechunge emihlanu ezinkulu izibuyekezo. Ngo-2001 waqala ukuba ikhishwe WR426F, futhi Yamaha WR450F - ngo-2003. Ngo-2007, ngokwesilinganiso, kwakubikwa Uhlaka aluminium, nophethiloli umjovo - ngo-2012, kodwa ngaphambi kule sizini libhayisikili ishintshile kancane. Lokhu ngeke kuthinte yokuthengisa, kodwa ngemva 2016 ngonyaka imodeli umnyuziki kulindeleke ukuba sibuyekeze a boom yangempela. Ukuhlolisisa ngokudlulisa amehlo ezinye izinguquko ezinkulu uye wembula 6-ganda isisindo ukulahleka, esikhundleni chassis kanye nokumisa, ukushintsha injini, gearbox ngcono futhi bopha uhlelo.

chassis

Ngo-2016, Yamaha wasungula kabili emaceleni aluminium Uhlaka kusukela Yzf, ukuthi uba ngokushesha zile uma kokufika.

WR kusukela ekuqaleni kuze kube sekugcineni inedizayini olinganiselayo kakhulu, isihlalo ukhululekile kuhlanganiswe enciphile 5 mm futhi inikeza footrest igxile kokwehla. Umehluko phakathi ozimele YZ futhi WR yakhelwe ukuzivumelanisa yokugcina ukuhambisa ezindaweni futhi ukwandisa ezingeni impendulo umshayeli. Futhi usayizi 2mm phambi injini ukumiswa kwehliselwe.

I Yamaha WR450F inohlelo olusha emine ibha ukuma, okuyinto sigcwalisa kahle iphakethe ubuyekeza Suv, njengoba ivumela umshayeli oyifisayo kokwehla ngaphandle kokungena ezindlekweni hardware eyengeziwe. Kungenzeka ukulungisa ukuma 26,5, 16.5 no-10 mm lokube, okuyinto kakhulu kushintsha usayizi abanikeze asebenza nabo. Ngokusho impendulo yomsebenzisi, kutilolonga isitayela yendabuko ukushayela isikhundla ejwayelekile kahle kokubili emgwaqeni omkhulu futhi ezindaweni ezimbi.

Ngaphezu kwalokho, ngesithuthuthu the Yamaha WR450F ifakwe ejwayelekile off-road amasondo yokulinganisa 18 futhi 21 amayintshi, okuyinto ayanikezelwa nge usebe Excel omnyama, hhayi isiliva njengakuqala. Lawa amathayi ezinhle Metzeler 6 Usuku oludlulele, njengoba ihlangabezana nemithetjhwana ezibekiweko FIM futhi kakhulu ezinzima.

Isimo sezwe ukulungiswa zihlanganisa ngokufakwa phezu ifreyimu ohlangothini-izinyathelo, fan kurediyetha, phambili izibani labaqaphi elingemuva. Ephoqelekile lwaluyophola Ukugunda kushisa nezigaba osindayo unqamule izwe lapho ukugeleza engokwemvelo emoyeni akwanele.

ukumiswa

Njengomhlaba chassis, ukumiswa WR450F 2016 kusekelwe YZ450F. Kuzo zombili isithuthuthu phambi ekuphambukeni isetshenziswa nge ngokwahlukana emoyeni-uwoyela KYB nge 22-mm displacement 114 mm ithrekhi futhi 26,2 ° caster engela, kodwa isetshenziswa WR ethambile kulungiselelwa yangaphakathi ehambisana kangcono ukushayela off-road.

A liyobhekana nesiphetho esifana kwamehlela ngemuva isithuthuthu, eyayibonakala isetshenziswa iziphethu KYB sebhithi Yzf ethambile ukubeka Enduro. Le ntuthuko ezincane ziye esenzelwe WRF ukubhekana zonke izici ogibele off-road, izigaba yomsebenzi umzila ngesivinini imigqa.

Sekukonke, uma kuqhathaniswa onobuhle langaphambilini, libhayisikili entsha Yamaha WR450F yokusingatha izici kanye amortization ngcono kakhulu.

Ngokusho nenjini-abalandeli, phakathi nohambo lwakhe lokuqala ukuya WRF kokusebenza phambi amagalelo ezithambile yezwakala, kodwa okwamiswa ngalo ukuba azizwa kanjani ngemva izinguquko ezincane clicker. Labo abakhetha ophezulu esifushane kakhulu futhi ethambile, kulandele ukusikwa ezijulile izinguquko ezingemuva ekuphambukeni wenza clicker ukunikeza le mizwa futhi kuzovumela ngokushesha axazulule nge isithuthuthu.

Lapho braking WR swings cishe kungabonakali ihlala ngokuqinile lapho kuyashesha ukuphuma emakhoneni flat, okuyinto ebaluleke for ngezimoto ezindaweni ezimbi. Motorcycle kakhulu kahle olinganiselayo e ukunyakaza lateral, okwenza kungabi nesidingo ukuze enyakazayo eqinile lapho cornering kokubili ngesikhathi ongaphakeme futhi ngesivinini.

Ukumiswa ukuthi "Yamaha" iye yathuthukiswa WR450F 2016, ngempumelelo ucedzela i chassis olusha futhi ihlinzeka esivikelekile, ukugibela kahle ukulinganisela. Ngokuvamile, abanikazi bayajabula nezinguquko ibhayisikili futhi ukwazi ukuthi Imigudu yokufaka neziphethu kalula kushintshwe ulungise isithuthuthu for abagibeli wonke amazinga.

injini

Ngo-2016 godu Yamaha wasungula injini lungiselelo elisha esekelwe Yzf, lapho ukuhlanekezela ungatshekisa chetyrehklapannyh isilinda ikhanda entsha kuhlangene phambi air eyanele futhi bakhulise qeda okukhipha amagesi. Reverse futhi bakhulise enyakazayo isilinda luyanda nekghono edonsa ukukhiqizwa, elungiselelwe komugqa torque ukunikeza yinye mass. umzimba 44 mm mpintsha, owawungumnyaka 2 mm ezingaphezu kuka ngonyaka odlule. Futha engela washintsha, izici ngcono kuvulwa mpintsha, iyiswe ukuziqalela okokunciphisa umsindo baba sifushane futhi ethulile. Angakwazi kokubili ngogesi futhi khahlela-isiqalo.

I generator inikeza ukuziqalela kagesi, izibani namandla uphethiloli umjovo uhlelo voltage 14 V kanye namandla 160 Watts. Ukuba khona izinhlobo ezimbili kwethulwa Yamaha WR450F Izibuyekezo umsebenzisi eziwusizo kakhulu, kusukela abanye abakhiqizi uncika electronics, futhi abanikazi lezi izithuthuthu ngaphambi kokuzibulala uhambo sina kaningi kakhulu nge ibhethri lingashajwa.

Kungakhathaliseki ukuthi ugesi efana kancane, bushelelezi, ephethe ukulibala, ezinzima noma ukushaqeka, okuholela dislocation ehlombe noma cha, sibonga idivayisi ozikhethela izilungiselelo amandla isithuthuthu kungenziwa uqobo ngokuvumelana bebodwa ukushayela isitayela.

Entsha ubuchwepheshe EFI kuqinisekisa kahle petrol, othobekile 7.5-litre fuel tank ivumela ozowela 100 km. Fans of elide travel ukwandisa umthamo wayo uzodinga ukuthenga izixazululo third-party.

Transmission

Esinye buyekeza ezinkulu ngo-2016 kwaba-gearbox ezinhlanu-speed. New ikhophi uhlelo design YZ450F, kodwa sihlanganisa, izinto ezintsha okuhlala isikhathi eside e kulula isango, Enduro, ukwazi ukumelana nezimo zokusebenza kakhulu. Ngaphezu kwalokho, uma kuqhathaniswa Yzf, yesibili, amagiya yesithathu neyesine baye bakhuliswa, futhi owokuqala eyesihlanu ayizange ithuthuke.

Ngokuvamile, ukudluliswa usebenza kahle, ukushintsha kwamandla ekhiqizwa olufana ngempela zimenyezelwe "ukukhanya" bamba. Ngaphezu kwakhe futhi Amalungu athishela okufunwayo akazange kuphakama, njengoba isilinganiso igiya 13:50 ube yimpumelelo enkulu zonke nabagibeli.

ukubopha

Uhlelo ukubopha Yamaha WR450F 2016 futhi wathola ukubolekisa kusukela Yzf. Ngenxa yalokho, libhayisikili manje has a esikhulu, 270 mm ububanzi phambi disc ukubopha maphambili umkhaza isibe kancane kancane.

the WRF braking ukusebenza, njengoba kulindeleke, kuyinto enhle kakhulu, abasebenzisi kudingeka kuphela encane ukulungisa ukuphakama front futhi bakhulise ukubopha iziyisikhombisa, ukuzizwa ekhaya. Abanikazi bathi lula unyathela amabhuleki okusheshayo uma ushayela kunoma iyiphi inhlobo sezwe, lapho wabavumela nokuzethemba okwengeziwe wazihlephula futhi lithuthuka, lapho-ke kwakudingekile.
