Barriers and fences were improved over time to prevent out of control vehicles from entering the spectator areas. During its 72-year operation the speedway hosted numerous Western Australian championships as well as national championships including the
Australian Sprintcar Championship, the
Australian Speedcar Championship, the
Australian Super Sedan Championship, the
Australian Solo Championship, and the
Australian Sidecar Championship. The speedway also hosted various rounds of the
World Series Sprintcars. Claremont hosted the first ever round of the inaugural World Series Sprintcars on 1 December 1987. The Speedway was in length. This made it the largest continually used speedway in an Australian state capital with the next biggest being the
Sydney Showground Speedway which closed for regular meetings in 1980 (the
Royal Melbourne Showgrounds track was long but it was only used infrequently, hosting at best one meeting per season). In its early days, the Claremont track was in fact larger than what it ended up asapproximately . However, the track was taken over to include seating in the spectator areas and was relaid to its 586-metre length. Soon after the development of the circuit records were set. In 1987, Claremont Speedway held the first, and to date only,
Sprintcar World Championship. The three-day meeting featured the top drivers from Australia,
New Zealand, as well as drivers from
America's famed
World of Outlaws series, and the youngest driver in the event, 15-year-old
Jeff Gordon. The event was won by legendary Australian driver
Garry Rush from local Perth driver
Alf Barbagallo, with American driver
Danny Lasoski finishing third. After 72 years of operation, the Speedway closed after the 1999/2000 season and the sport moved to a new, venue at the
Quit Motorplex, near
Kwinana which opened in 2000. While the new Motorplex generally caters to car racing, it does contain a
motorcycle speedway track inside the main track, and even though it hosted rounds of the
WA Solo Championship in 2001, 2002 and 2005, solos and
sidecars generally raced out of the
Bibra Lake Speedway located in the southern Perth suburbs until its closure in 2004, before moving to the new, bike-only
Pinjar Park Speedway at
Wanneroo in northern Perth which opened in 2005, bike racing made comeback at Perth Motorplex during the 2018/19 season. The departure of the speedway at Claremont allowed the main showground arena to be redeveloped into a more open area, suitable for large music events such as the
Big Day Out and other festivals as well as for sports such as
Australian rules football and
cricket. Through its history, Claremont was home to a number of Australia's best speedway riders and drivers, including
Sig Schlam,
Chum Taylor,
Glyn Taylor,
David Cheshire and
Glenn Doyle (Solo's), Keith Mann, Johnny Fenton, Neville Lance, Tom Watson Sr and Michael Figliomeni (Speedcars), Dennis Nash, Ed Blakeney Sr, Rod Lang and Russell Mitchell (Sidecars), Noel Bradford,
Alf Barbagallo and
Bunbury's Ron Krikke (Sprintcars), and Allan Blake, Ben Ludlow, John Singleton, Bert Vosbergen and Craig Vosbergen (Sedans), Johnny Andersson, Bill Broadwood, Vince Chapman, George Higgs, Ken Nielson, Bryan Mullings (Formula 500, TQ's) ==Sponsorship==
