Lub ntuj evolution ntawm niaj hnub maus taus yog txav mus rau ntau kev nplij siab, ntau ceev, ntau kev cia siab. Cov cheeb tsam uas tsis yog prerogative ntawm mono. Tseeb tiag, tsis muaj qhov sib npaug thiab muab qhov tsis zoo rau lub cev tsis tu ncua, nws tawm tsam nyuaj ntawm qhov qis qis, uas tau txais nws lub npe menyuam yaus "Tuper" (tus cogner hauv Shakespeare cov lus). Tsis tas li ntawd, hauv kev tshawb nrhiav kev ua haujlwm, ib lub tog raj kheej qeeb qeeb. Nws ua rau kev txiav txim siab, vim tias txhawm rau kom muaj zog, koj tuaj yeem nce qhov kev hloov pauv lossis lub cav ceev. Hauv ob qhov xwm txheej, nws lees nws qhov kev txwv. Yog tias qhov hloov pauv nce, lub piston tau loj dua, yog li hnyav dua. Qhov tseeb, lub zog ntawm inertia uas ua rau hnav thiab kev vibration nce tib lub sijhawm. Tib qhov teeb meem yog tias peb tab tom sim kom ncav cuag qhov nrawm, vim tias lub zog inertial tsim ntawm lub xwmfab ntawm qhov nrawm, peb ntsib tib yam kev pheej hmoo ntawm kev tawg, hnav thiab kev co…. Yog li ntawd, mono yuav tsum txwv rau nruab nrab rog, tsis muaj peev xwm ua txuj ua txhaum cov ntaub ntawv…. Qhov tseeb tiag, nws qhov kawg ntawm Pawg Thawj Tswj Hwm yeej yog xyoo 1969. Nws yog Norton Mans, thiab kev sib tw tau los nag. Tom qab ntawd ntau lub tog raj kheej, 2 thiab 4 strokes, thaum kawg hloov nws.
Tom qab tsov rog, lus Askiv ib lub tog raj kheej sab saum toj yog qhov kawg riam phom ntawm kev xaiv rau cov neeg tsav dav hlau uas xav khiav tawm. Txawm li cas los xij, lawv yuav tsum tau hloov cov thav duab hauv xyoo 1960s thaum lub ntsej muag ntawm kev nce qib hauv ob-stroke thiab ntau lub tog raj kheej. Ntawm no yog Matchless G 50: Nws yog tus neeg sib tw rau Norton Manx. Nws nthuav tawm lub cav ACT yooj yim.
Yamaha rov xav nrov nrov
Kuv yog lus dab neeg. ACT ib lub tshuab cua txias 2 valve cav, pib poob siab thiab nruas nres. 500 XT yog qhov sib txawv ntawm kev nce qib, tab sis nws yuav raug ntaus. Nws yog rau nws tias peb yuav tsum rov qab thunderous.
Txawm li cas los xij, xyoo 1976 Yamaha tau hloov kho cov thev naus laus zis no, pom nws qhov chaw hloov kho zoo kawg nkaus: Hla Tebchaws Kev Ua Haujlwm. Ua ke, kev lag luam, tag nrho ntawm tus cwj pwm, tib lub tog raj kheej yog kev vam meej thoob ntiaj teb ntawm 500 XT. Kev sib tw ua raws li kev sib tw sai heev, thiab qhov tshwm sim tau coj mus rau qhov tsis txaus ntseeg nrog kev txhim kho ntawm Paris Dakar. Txoj kev ib lub tog raj kheej ces dhau los ua lub cim ntawm kev ywj pheej, taug txuj kev nyuaj thiab kev khiav tawm. Peb nyob kaj ntug xyoo 1980. Tab sis keeb kwm stumbles thaum BMW sib tw nrog nws nto moo tiaj tus ntxaib. Txawm hais tias nws txoj kev siv zog, nce kev hloov pauv, sib npaug li qub, ob chav ACT, thiab lwm yam, lub mono yuav tsis tuaj yeem tiv taus ntau lub tog raj kheej nthwv dej. Ua txoj kev asphalt, nws hneev mus rau hauv cov xuab zeb txoj kev. Tuag lawm tiag? Tau kawg tsis yog, ib lub tog raj kheej yog rustic mechanism uas tuaj yeem tiv taus kev tsim txom. Yog li ntawd, nws yuav rov yug los ntawm nws cov tshauv, zoo li Phoenix.
Lub bastion kawg, lub xeem battles
Rov qab rau hauv Grace: Kev siv thev naus laus zis sib tw tso cai rau cov monos rov qab los rau lub zog thiab yeej ob zaug hauv kev pom zoo ntawm kev sib npaug. Lub TT tseem yog tib qho chaw uas Hi-Tech ib lub tog raj kheej tseem muaj. Ntawm no yog upside-down Yamaha 450 ntxaib ACT Yamaha XNUMX lub tog raj kheej taub hau thiab txhaj tshuaj.
Tam sim no tsuas yog lwm txoj hauv kev yog qhov huv thiab tawv SUV. Ntawm no, qhov hnyav thiab compactness yog ib qho tseem ceeb zoo uas hla lub zog ntshiab. Nws yog tsis yooj yim sua mus taug kev ib puas los yog ntau tshaj nees los ntawm av nkos struts uas muaj pob. Nws tseem tsis tuaj yeem ua tau zoo nrog lub tshuab hnyav txog 200 kg. Tsis muaj chaw rau ntau lub tog raj kheej (tsis tau). Tab sis txog thaum tsis ntev los no, 4-stroke mono tsis tuaj yeem tawm tsam 2-mob stroke nrog sib npaug. Tab sis thaum nruj cov txheej txheem tswj cov pa phem thawb lub laub-rub mus rau qhov tawm (emphatically, keeb kwm rov ua nws tus kheej dua!), Nws imposes nws tus kheej. Nyob rau hauv kev txaus siab ntawm qhov sib npaug ntawm qhov sib npaug ntawm 125 2 ntsis / 250 4 strokes thiab 250 2 ntsis 450 4 strokes, peb pom kev yug me nyuam tshiab ntawm nruab nrab txav ib lub tog raj kheej uas muaj zog, hnav thiab ua haujlwm zoo. Lub cim tshiab no ntawm high-tech ib lub tog raj kheej tsis tuaj yeem suav. Ob chav ACT, 4 titanium li qub, kua txias, forged pistons ... Lawv zoo tshaj 100 hp. thiab tuav ceev ntawm 13000 rpm ntawm 250 !!!
Qhov no mutant yug yog saib ntawm asphalt dua ua tsaug rau supermodern zam, nrog rau lub ambition xwb los reclaim av no. Mono nyuaj!
Austrian chaw tsim tshuaj paus KTM tseem yog tus kub tshaj plaws ib lub tog raj kheej tiv thaiv ntawm txoj kev. Qhov kev ua tau zoo thiab kev ntseeg siab ntawm nws 690 yog breathtaking rau mono. Ntawm no yog 500 EXC cav.
Box: 2 ib
Lub zog compact, lub teeb yuag, yooj yim, 2-stroke ib lub tog raj kheej muaj nws cov sijhawm ua haujlwm zoo kawg nkaus.
Cov evolution tsis ntev los no ntawm cov pa phem abatement qauv tau disqualified nws me ntsis, tab sis nws kuj tsis muaj nws lo lus kawg ... TT pilots uas xaiv valve engine tsis tas yuav integrate los yog zom cov nqi khiav hauj lwm ntxiv uas yuav ua rau qhov no. Ntau lub cav uas khiav nrawm dua, xav tau kev saib xyuas ntau dua (valve clearance checks, tis chain, high wear of titanium li qub nrog plua plav ...). Tag nrho cov no yog kim ... Ib txhia pib xav tias thaum kawg, lub tog raj kheej nrog lub qhov ... Nws tsis yog li ntawd phem!
