The BMW R65 was a light touring motorcycle introduced by BMW in 1978 to add a mid-size motorcycle to its product line. The original R65, with a smaller frame than larger R series motorcycles, was manufactured until 1984. In 1985 the R65’s engine was put into the new (and larger) R80 frame which featured a single rear shock absorber (mono-shock). 〔Zimmerman, Mark & Nelson, Brian J. (2003).

This R65 variant had a small triangular fairing that was designed by Hans Muth.〔Zimmerman, Mark & Nelson, Brian J. (2003). BMW Motorcycle Buyer's Guide. MotorBooks/MBI Publishing Company〕 ==Technical overview== The R65 is fitted with a type 248/1 engine, a different version of the well known BMW type 247, also known as an airhead. The engine is an 648 cc, OHV, two valves per cylinder, air-cooled flat-twin (i.e., horizontally-opposed cylinders) or "boxer" engine. The R65 weighs 205 kg (455 lb) with a full tank of fuel and has a five speed gearbox connected to a shaft final drive.〔(【引用サイトリンク】 publisher= BM Bikes )〕 From 1981 on, the R65 was fitted with breaker-less electronic ignition. This further improved the already good reliability of the bike. Following standard BMW practice of the time, two 32 mm Bing CV carburettors were used and the R65 used a single dry plate clutch. An additional lower powered version was also produced for the German market and was fitted with 26 mm Bing CV carburettors. The R65 features a smaller fuel tank than other larger BMW airheads, with a capacity which includes a 0.5 gallon reserve. The monolever version of the bike was produced from 1985 until 1993. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BMW R65」の詳細全文を読む スポンサード リンク
