The Italjet Dragster (1998–2003) of the Italian manufacturer Italjet Moto is so far the only mass-produced scooter with a RAAD forkless front suspension and a spaceframe. Alessandro und Leopoldo Tartarini obtained a patent for this combination in 1997.〔(EP 0757950 A2 )〕〔(Patent )〕 == Technology == The forkless front suspension is very unusual for motorcycles, and the Yamaha GTS 1000 (1993–1997) might have been the inspiration for the Tartarini brothers. They applied a very innovative technology and an unusual design to their scooter. :"This scooter is nothing for pragmatists, but a good choice for exhibitionists"〔Motorrad Test 2001, p. 218〕 All ''Dragster'' marks are based on a space frame, which was obviously designed for more power. The front wheel had the dimensions 120/70–11 and the rear wheel 130/70–12, only the mark 2007 had a 130/60–13 rear wheel. The wheelbase was 1310 mm.〔Motorrad catalogue 2002/2007〕 The mark ''Dragster 50'' was re-edited in 2007 in addition to the mark ''Dragster 250''. The forkless front suspension was criticised as leading to "non-harmonic and wobbly dynamics at lower speeds."〔 Some critics complained about the noise level of the large water cooled two stroke engine, which had a catalyst: :"It is impossible to drive with ''Dragster 180'' through a quiet estate, but those who buy it, don't want to do that anyway."〔 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「Italjet Dragster」の詳細全文を読む スポンサード リンク
