The Italjet Dragster of the Italian manufacturer Italjet Moto is the only mass-produced scooter with a RAAD forkless front suspension and a spaceframe. Alessandro and Leopoldo Tartarini obtained a patent for this combination in 1997.[1] A rebooted version has been displayed, and expected to be available from early 2021,[2] with 125cc or 200cc four stroke engines.

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"[3]

All Dragster marks are based on a space frame, which was designed for more power. The wheel dimensions are 120/70–11 front and 130/70–12 rear. The 2007 models had a 130/60–13 rear wheel. The wheelbase was 1310 mm.[4] 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."[3] Some critics complained about the noise level of the large water cooled two stroke engine, which had a catalytic converter.

"It is impossible to drive with Dragster 180 through a quiet estate, but those who buy it, don't want to do that anyway."[3]
