Anthony Keith West,[1] (born 17 July 1981 in Maryborough, Queensland), is an Australian motorcycle road racer.

[2] West was suspended from participating at any FIM sanctioned events for 24 months due to testing positive for banned substances from 8 July 2018 to 14 September 2020.

He is known as "The Rain Man" because of his ability to ride well in the extreme wet, which he attributes to a dirt track racing background.

In the 2003 and 2004 seasons, West rode for the Italian Abruzzo Racing team, running a privateer Aprilia both years.

2005 was supposed to be his big break, but a factory deal with KTM saw him miss three quarters of the season due to a lack of development and several mechanical failures.

Early in the 2007 season, he rode in the 250cc World Championship on a semi-factory, LE Aprilia run by Matteoni Racing.

A disappointing start to the season saw West unable to match the times he set on the Kiefer Bos bike in 2006, with a best result of ninth after the fourth round of seventeen, leading him to quit the team.

However, West enjoyed more success when, at the Monza round of the 2007 World Supersport Championship, he rode through the field from 18th on the grid to finish 3rd, while substituting for injured compatriot Kevin Curtain on his first visit to the track, on his first race aboard the Yamaha.

[7] He made a good debut at the British Grand Prix, reaching fourth position, but then crashing and eventually finishing 11th.

[8] His first four races each saw him finish progressively higher, with seventh at Mazda Raceway Laguna Seca and eighth at the Sachsenring.

In his home country's Grand Prix the Australian's error caused him to only finish 12th while compatriot Casey Stoner won aboard his Ducati.

At the following race in Malaysia, Sepang, West qualified an impressive fifth behind teammate Randy de Puniet but was yet again given a ride through penalty, this time for lining up incorrectly on the starting grid.

On 16 October 2008 it was announced that West had signed to ride for the Stiggy Honda team for the 2009 World Supersport Championship, cutting his ties with Kawasaki.

Further drama was to come however, when West's fellow countryman Damian Cudlin was dropped from the QMMF Moto2 Team after struggling with the Moriwaki machine in pre-season testing.

On 31 October, it was announced that a sample that West had provided for testing at the French Grand Prix contained traces of methylhexanamine, a banned substance.

West was stripped of his seventh-place finish in the French Grand Prix and was banned from competing in any FIM-sanctioned race for one month.

In November 2013 the Court of Arbitration for Sport ruled on an appeal by the World Anti-Doping Agency against the decision of the Fédération Internationale de Motocyclisme to only ban West for one month following his positive drug test in 2012.

[13] In 2014, West remained again with QMMF Racing Team, this time partnered by Spanish rookie Roman Ramos.
