I-2021 Honda CRF300L neCRF300L American Rally kumenyezelwe

Njengoba uDennis Chung, owesilisa wakwaHonda eToronto, aqagela ngesikhathi iHonda Europe imemezela lezi zindaba ekuqaleni kukaDisemba, imoto yezemidlalo entsha neyenziwe ngcono yakwaHonda izongena emakethe yaseMelika. Eqinisweni, uHonda uthe iCRF iyimidlalo emibili edayiswa kakhulu embonini yezithuthuthu.
Nge-CRF300L ne-CRF300L Rally entsha, umsebenzi ukukhulisa amandla, ukunciphisa isisindo nokwenza ngcono ukusebenza komgwaqo? "Ngaphandle kokunikela ngenani, ukuthembeka nokubukeka kwesitayela, la magugu, ukubaluleka nokwethenjwa kudlale indima ebalulekile ekuthandweni komshini." Yize sikuqonda ukuthi le mishini emibili icishe ifane ngokusebenza, ngaphandle kwamandla kaphethiloli, Ngaphezu komehluko phakathi kwesigadli esijwayelekile nefasitela lomoya elinefreyimu lemoto ye-rally, sifaka nokukhishwa okuphelele kwabakwaHonda kwalezi zinhlobo ezimbili ezingezansi.
Amandla angeziwe ne-torque kutholakala ngokwandisa ukufuduka ngo-15% -kusuka ku-250 kuye ku-286 cc ngenkathi futhi kuthuthukiswa ukusebenza kwasemgwaqeni ngokwandisa ukushaywa kokumiswa nokususwa komhlaba. Ngasikhathi sinye, abakwaHonda bathi isisindo semoto sisonke sehliswe ngamakhilogremu ayi-11, okutholakala kakhulu ngokusebenzisa ukuhlaziywa kwezobunjiniyela okusizwa ngamakhompiyutha ukukhulisa ukushuba kwepuleti nosayizi wamabhubhu ezintweni ezingenakubalwa. Amathiphu wesitayela aqhamuka ochungechungeni lwe-Honda's CRF Performance, ngenkathi i-MSRP "isencintisana kakhulu."
Ngomzimba wayo kanye nemidwebo ebomvu, emhlophe, emnyama nokumnyama, i-CRF300L ihlose ukulingisa ukubukeka kochungechunge lweCRF Performance, kufaka phakathi i-Baja-based CRF450X.
Indawo yokugibela Indawo yokugibela ishintshiwe ukuze kuthuthukiswe okokufaka kwabagibeli nokuhamba kwezimoto. I-angle yokushanela yebamba yokubamba iyakhushulwa ukwenza indawo yendololwane ibe yemvelo ngokwengeziwe, ukuqondisa kube lula, futhi isisindo sesibambo siyakhushulwa ukunciphisa ukudlidliza. Ububanzi bezindawo ezingemuva naphakathi esihlalweni buhlala bunjalo ukugcina ukunethezeka, kanti indawo engaphambili incane ukuthuthukisa okokufaka kwabagibeli ngamathanga namadolo.
