Yamaha WR 250R

• Kanema: Yamaha WR 250 R

Ngati mukuwonera motorsport yonyansa, mwina mukudziwa kuti njinga zamoto zokhala ndi injini ya 250cc yama sitiroko anayi. Cm amapikisana m'kalasi lomwelo ndi njinga zamoto zamagalimoto 125cc zama stroke awiri. Cm.

Mwachidziwitso, injini ya sitiroko iwiri imakhala ndi mphamvu zowirikiza kawiri voliyumu yomweyo, motero kuyiphatikiza m'gulu limodzi ndikomveka komanso koyenera. Chifukwa chiyani ndikulankhula zamakalasi othamanga pomwe tikulankhula za galimoto yamagudumu awiri yomwe sinapangidwenso mwangozi kuti ipikisane? Chifukwa pomwe ndimayendetsa Yamaha watsopano ndidakhala ndi lingaliro loti malamulo omwewo angagwire ntchito panjira.

Ndi WR250R, ana a zaka khumi ndi zisanu ndi chimodzi amatha kukwera mwalamulo ndi abwenzi omwe amayendetsa galimoto, mwachitsanzo, Yamaha DT 16 ma stroke awiri. Zonse zili bwino, koma vuto ndi akavalo. Mwalamulo, azaka za 125 akhoza kukwera njinga yamoto ndi "akavalo" ochuluka a 16, ndi pa keel yoyesera - mpaka 15. Mibulu, mwatsoka, iyenera kuyembekezera zaka ziwiri. Komabe, pamene kuyesa kwa voliyumu yopanda malire ndi mphamvu zili m'thumba lanu, aliyense amakonda kufika panjinga (yamphamvu kwambiri).

Ndiroleni ndikugawane nanu malingaliro omwe ndidakumana nawo pomwe ndimachoka pagalimoto ya Yamaha ku Rudnik: njinga ndi yayikulu mokwanira, chiwongolero ndichomwe chikuyenera kukhala pa enduro, ndipo mphamvu ndiyokwanira kuyendetsa ndege pa liwiro lomwe simunalipidwe chindapusa.

Kuthamangira njinga yamoto yamtunduwu sikosangalatsa. Pomaliza, nayi njinga yamoto yomwe ndimatha kukwera m'misewu ndikuthawa panjira pamene ndikufuna kuyendetsa pamisewu yamiyala. Kodi ndikufunikiranso zina?

Ndisanapite kumtunda wamakilomita angapo oyambilira, ndinkaganiza kuti iyi ndi XT125R yamphamvu pang'ono, yokulirapo komanso yokonzanso, yomwe ndi kugula kwabwino pamtengo wake, womwe umatsimikizidwanso ndi manambala ogulitsa, komabe sikusangalatsa kwenikweni tchuthi chachikulu. kuyendetsa pamsewu. Kukonzekera uku kunakhala kolakwika popeza WR250R ndiyatsopano.

Choyera chopepuka ndi cholimba chimapangidwa ndi aluminiyamu, kuyimitsidwa kumakhala kosinthika, ndipo injini imodzi yamphamvu imagwiritsidwa ntchito pamagetsi ndikukhazikika madzi. Tiyeni tiwone koyamba jenereta: imanyezimira bwino ndikupanga utsi wodekha, womwe amayamikiridwa kwambiri ndi oyendetsa m'munda. Ngati simukuthamangira, mutha kukwera ma liwiro otsika pomwe njinga imakoka bwino osagogoda. Komabe, zikuwoneka kuti cholembacho sichikhala chachikulu kwambiri, chifukwa chake chimayenera kuzungulira mozungulira kwambiri kuti chikhale chothamanga kwambiri.

Izi zimatengera kuzolowereka, apo ayi mutha kupezeka kuti muli pamalo pomwe gudumu lakumbuyo silichita mwamphamvu momwe mungafune. Yankho lake ndi losavuta - ngati mutasinthira ku giya yotsika, "okwera pamahatchi" 30 amoyo adzagwera pansi.

Izi ndizokwanira kuti athe kukwera malo otsetsereka owopsa ndikupangitsa kukwera m'malo ovuta kukhala chosangalatsa kwenikweni. Clutch ndi drivetrain ndibwino, koma mwatsatanetsatane mwamasewera sizili choncho. Choyamba, ndikufuna ndikhale ndi lever yayitali, chifukwa idapangidwa kuti izitha phazi lokwanira nsapato # 40.

Yamaha atha kudziwa kuti Mularium (mwamwayi) amakonda kuvala zida zapamwamba, zomwe zimaphatikizaponso nsapato za motocross, zomwe timalimbikitsa kuti tikwere.

Njinga yamoto ndi chidole chenicheni pabwalo, chomwe sichingasiye osayanjanitsika padziko lonse lapansi oyendetsa galimoto. Kuyimitsidwa kwanthawi yayitali kumatenga mabampu bwino ndipo mutha kulumpha mosavuta, kokha omwe amafunikira kwambiri angafune mphamvu zambiri. Koma monga tikumvetsetsana, iyi si galimoto yothamanga, koma galimoto yabwino kwambiri tsiku lililonse.

Mabuleki akutsogolo ndi kumbuyo amakhala ndi mphamvu zokwanira kuti asagwedeze wophunzirayo akamakankhira wolowererayo mwamphamvu pamalo osauka. Bicycle ndi yopyapyala kwambiri pakati pa miyendo, ndipo poganizira kuti iyenera kukhala yoyenera panjira ndi kukwera pamsewu, mpando umakhala wokwera bwino.

Thanki mafuta ndi lokoable ndipo amanyamula malita 7 a mafuta, kutanthauza kuti muyenera kusiya pa mafuta pafupifupi makilomita 6. Ngakhale sitinadandaule ndi injini imodzi yamphamvu, kuchuluka kwake sikunapitirire malita asanu.

Ngati chizindikiro chomwe chili mu kabuku ka pinki sichikulolani kugula njinga yamphamvu kwambiri, kapena ngati mukutsimikiza kuti 250cc ndi yokwanira, WR250R ndi chisankho chabwino kwa iwo omwe amakonda kuphatikiza zosavuta za tsiku ndi tsiku ndi masewera akunja. Pongoganizira, XT660R yocheperako pang'ono koma yamphamvu kwambiri ndiyochepera $500 ina.
