<h2><b>傳承DT-1血脈的 Mini Trail 迷你越野車</b></h2>
<p><span>1967年在東京車展(MC Show)上首次亮相的Yamaha「DT1」，是根據摩托越野賽車YX26的反饋設計而成，成功地為Yamaha建立了擅長生產越野車的聲譽。1960年代，迷你摩托車風潮興起，，各大廠紛紛推出排氣量約在50～80cc的各式迷你車型。</span></p>
<p>就在這波迷你摩托車風潮中，1970年Yamaha推出了越野車型「FT1」。FT1 彷彿是DT-1 的縮小版，搭載了一具50cc二行程旋轉閥式引擎，外型設計充滿迷你越野車的特色。翌年（1971年），這款車型更名為「FT50」，並在1972年進一步改款為搭載活塞閥式引擎的「Mini GT50/80」。</p>
<p>這款GT50/80則被愛好者暱稱為「Mini Trail」，並迅速走紅，成為當時年輕騎士們心中的熱門車款。</p>

<p><span style="font-weight: 400;">Mini-Trail類型的越野摩托車中，SUZUKI於1975年推出「MiniCRO 50/75」，HONDA則於1976年推出「XE50/75」。GT50/80於1979年進行全面改款，導入後單槍避震系統，車身設計也變得更大。</span></p>

<h2>GT50/80被譽為「名機」能夠使用30年的長壽引擎！</h2>
<p>此次拍攝的是一款1978年式的Yamaha GT80III，作為配備雙槍後避震的初代車型中的最終版本。配備了容量4.8L的緊湊型油箱，搭配略大的座椅，前後擋泥板則是當時典型越野車風格的簡約設計。車頭燈尺寸小巧，與車身比例相符，但方向燈和尾燈的尺寸略顯大，似乎與車身比例有些不協調。排氣管採用越野車常見的上繞式設計，而在1977年進行小改款對外觀進行了微幅調整。</p>

<p sandboxuid="0">Yamaha GT50/80是搭載風冷二行程活塞簧片閥單缸引擎(Air-cooled 2-stroke piston reed valve single cylinder) ，GT50排氣量49cc（缸徑x行程：40&#215;39.7mm），GT80則為72cc（缸徑x行程：47x42mm）。早期車型GT50最大馬力4PS/7500rpm，最大扭力0.45kgm/5000rpm；GT80則分別為4.9PS/6500rpm和0.55kgm/6000rpm。</p>
<p sandboxuid="0">初期型號的變速箱採用了四速「底部空檔式」相當獨特的循環式設計，空檔位於一檔下方，換檔踏板為翹翹板式，踩腳後跟即可升檔，踩腳尖則進行降檔。這樣的設計在1977年後，改為常見的五速循環式變速系統。引擎啟動方式為腳踩發啟動。此款迷你越野車款的引擎後來也應用於在Yamaha YSR，而作為基礎的GT50引擎則延續使用在YB-1等車型上，成為一款壽命長達約30年的耐用引擎。</p>

<h2><b>GT50/80緊湊的車體設計</b></h2>
<p>GT50/80 配備15吋前輪與14吋後輪，車身全長為1610mm，取自基礎車型 DT-1 全長2060mm的80%而設計。座高略低僅655mm，完全符合Mini-Trail的尺寸定位。</p>
<p>車架採用鋼製單搖籃設計，前避震為Telescope Type 潛望式，後避震為雙槍式。後搖臂與車架相同為鋼製，前後煞車均為鼓煞配置。在當時的50cc級距車型中，GT50/80的車身配置相當完善。1972年的售價分別為GT50的7萬4000日圓和GT80的7萬7000日圓，可謂物有所值。</p>
