450SMX Class: Joliet Recap

Jetting Towards the Title: Jett Lawrence scorched Chicagoland for an overall victory and a great shot at winning the 450 SMX Championship as he is only two-points off the red-plate. The victory was his 39th career AMA victory (13 250SX, 11 450 Class, 14 250 Class, 1 SMX Playoff) and he is now alone in 17th on the all-time wins list.

450SMX Class: L.A. Memorial Coliseum Historical Facts

History Lesson: The first ever race at the Los Angeles Memorial Coliseum was on July 8, 1972 and 16-year old Marty Tripes took the overall on his Yamaha. He went a consistent 2-2-2 to ward off three Swedish riders who took Moto wins ahead of him; Torlief Hansen, Arne Kring, & Haken Andersson. The race was Round 2 of the Inter-Am National Championship and Rd. 10 of the first ever AMA National Championship series. This race is considered one of the first true “Supercross” races in the sport’s history. American Yamaha teammates Gary Jones and Jimmy Weinert would finish in fifth and sixth overall after Tripes and the Swedes.

Tripes Backs It Up vs. the Euros: The “Superbowl of Motocross” returned to the L.A. Memorial Coliseum the following season in 1973 under the same Inter-Am/AMA National Championship format. Now 17-Years of age, Tripes shocked the Europeans yet again this time with a 1-1-2 performance compared to his 2-2-2 performance from ’72. Jim Pomeroy won the third Moto and finished second overall with a 3-3-1 day to give the Americans first and second on the day. In 1974 the Superbowl of Motocross was held as a stand-alone “Americans vs. Europeans” race and was won by Jaroslav Falta on his CZ and Roger DeCoster scored a second on his Suzuki. ’72-’73 winner Tripes finished third on a Husqvarna.

Tradition Continues: Starting in 1975 the L.A. Memorial Coliseum race was solely a part of what is now the Monster Energy AMA Supercross Championship. This continued through 1992 (including two in ‘80 and sans ‘83), before the series took a five-year sabbatical from The Coliseum. Racing returned to The Coliseum in 1997 with two rounds of Supercross and in 1998 with a single round, a surprise opener win by Sebastian Tortelli. AMA racing has not returned to The Coliseum since then but boasts 24 Premier Class races from 1972-1998.

Dodger Stadium/Rose Bowl: Los Angeles County also hosted Supercross events in 1983-1985, 1990, & 1993 at the Rose Bowl and more recently in 2011-2012 in Dodger Stadium. That would make the 2023 SMX Playoff Finale the 32nd Premier Class race in Los Angeles County and 25th hosted at the Los Angeles Memorial Coliseum.

250SMX Class: L.A. Memorial Coliseum Historical Facts

History Lesson: The first 250 Class race held at the L.A. Memorial Coliseum was on May 11, 1985 and was the penultimate round of the first season of 250SX Class racing (then 125cc). Larry Brooks would win on a Honda while Eastern Regional Champion Eddie Warren finished eighth and eventual Western Regional Champion Bobby Moore finished 10th.

More History: 1986 L.A. Memorial Coliseum hosted the finale for the Western Regional Supercross Championship. Donny Schmit’s third-place finish clinched the title for him over the night’s winner Willie Surratt. Surratt would secure the title the following season in The Coliseum with a second-place finish over Robert Naughton who finished seven-points back in the Championship. In 1988 the L.A. Memorial Coliseum hosted the finale for the Premier Class series and hosted an “Ultra-Cross” exhibition format race that was won by Willie Surratt in lieu of a traditional Regional round. The Championships were decided with the Western Regional final in Irving and the Eastern Regional final in East Rutherford.

Coliseum/Dodger Stadium/Rose Bowl: Regional racing resumed in 1989-1992 and just like the Premier Class would return in 1997 for two races and one in 1998. The Rose Bowl hosted 250SX Class races in 1985 as the Western Regional finale in the first ever 250SX Class series (then 125cc), 1990, & 1993. Just like the Premier Class, 250SX Class racing visited Dodger stadium in 2011-2012. The 2023 SMX Playoff Finale at the L.A. Memorial Coliseum will be the 11th time 250 Class racing has visited The Coliseum and 16th time visiting Los Angeles County.

Championship %: With the L.A. Memorial Coliseum being winner takes all in the 250SMX Class (between H-Law, Deegan, & Shimoda) and the 450SMX Class (between J-Law, Roczen, & Sexton) we examine previous winners of The Coliseum and how the fared in their respective title chases: In the Premier Class 6/23 winners went on to win their Championship. 1974 was a standalone race and does not count in that number. In 250 Class racing the number is 4/10, bringing the total to 10/33.
