The Aprilia RST1000 Futura is a sport touring motorcycle that was produced by Aprilia from 2001 to 2004. It is equipped with a 113 horsepower (85 kW) four-stroke 60° V-twin engine with electric-start, liquid cooling and electronic fuel-injection. The engine is broadly similar to that fitted to the Aprilia SL1000 Falco. With its hard-shelled panniers, the Futura was intended to compete with the similarly styled Honda VFR800,〔(【引用サイトリンク】title=Honda Interceptor ergonomics )〕 but poor sales and Aprilia's worsening financial position led to the Futura's demise. Production ended in 2003, although the bike remained in the range until 2005. ==Design== The Futura incorporated an aluminium-alloy, double-parallel-beam frame with a single-sided swinging arm. Transmission is ''via'' a six-speed gearbox and chain-final drive. Other features included CDI dual ignition system using two spark plugs per cylinder, dry sump lubrication, mixed gear/chain timing, (AVDC) double-balance countershaft, and power-assisted hydraulic-controlled clutch, with a patented Pneumatic Power Clutch" (PPC) to simulate a slipper clutch to control rear-wheel bounce during sudden deceleration.〔(【引用サイトリンク】url=http://www.motorcyclistonline.com/roadtests/aprilia_futura/index.html )〕 〔(【引用サイトリンク】url=http://www.cycleworld.com/2010/08/13/aprilia-rst-1000-futura-best-used-bikes/ )〕 The Futura's dry weight is 210 kg (463 lb). The chief designer in charge of the project was Pierluigi Marconi. He would design the Futura around the same motor used in the Mille, a 998cc DOHC 60 degree V-twin. Among major changes from the Mille were the single side swing arm and undertail exhaust used to retain space for the hard sided luggage.〔(【引用サイトリンク】url=http://www.apriliafutura.co.uk/v2/owners-guide/about-the-aprilia-futura/56-futura-development-the-inside-story.html )〕〔http://www.apriliafutura.co.uk/downloads/documents/Marconi012.jpg〕 Marconi also specified an increase in the electrical generator in order to cope with accessories that touring riders were sure to add. Electrical capacity was increased by 30% over that of the Mille. Marconi directed his design team to spend an extensive amount of time on the exhaust system. The result was that it did not heat up the seat as other undertail exhausts did. It also passed Euro 1 standard emissions without the catalytic converter. The design team moved to supplier Sagem to provide the fuel injection and intake systems. Marconi would later quit to work with Benelli and then later Gas-Gas. It is his leaving Aprilia that caused promised updates like ABS and power outlets to never materialize on the Futura. 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「Aprilia RST1000 Futura」の詳細全文を読む スポンサード リンク
