Jeff Alessi, Pro Motocross and Monster Energy Supercross Rider, Passes Away at 34

According to family members, Jeff Alessi passed away on the eve of October 2, 2023. He was 34 years old.

Alessi was a former professional supercross and motocross rider from the United States. He was born in Victorville, California on March 27, 1989. The brother of Mike Alessi started his racing career in Southern California with various local clubs, predominantly with the California Racing Club – commonly referred to as CRC. Growing up and racing through the ranks, the Alessi brothers raced at iconic motocross tracks such as LACR Raceway, Glen Helen Raceway, and Desert Wheels Motorcycle Club located on the property of Edwards Air Force Base.

Jeff Alessi made his first career start in the big leagues in 2005 at Hangtown Motocross Classic where he finished 23rd in the 450 class, the highest division in Lucas Oil Pro Motocross Championship racing. From there, he continued to race in both 250 and 450 divisions in both Motocross and the Monster Energy AMA Supercross series.

In Pro Motocross, he earned one top 10 finish in 250 and nine top 10’s in the 450 class. For Supercross, he placed 11 top 10’s in the 250 division with a career-best finish of fifth at Anaheim 3 in 2009.

Jeff Alessi mostly competed from 2005 until 2012, and last competed professionally in October of 2016 in the Monster Energy Cup making the main event with a 22nd place result.

His passion for dirt bike racing went beyond himself. He opened Jeff Alessi’s Riding School in 2016 where he held multiple coaching and riding camps for young athletes to learn the basics of racing, motorsport safety, rider etiquette and more. Some of his riders would go on to compete in the iconic Loretta Lynn Ranch AMA Amateur National Motocross Championship.

May the 801 plate rest in peace.

  1. Heartfelt condolences to the Alessi Family for the passing of Jeff Alessi, a beloved and admired promotocross rider/racer. May he Rest in Pease.

    1. May your hearts heal with his soul.and always cherish the memories ,moments you had with him as he was full of life ,love ,and will be waiting to see you again never forget who he was may be rest in peace .

        1. Actually he sounds like an educated person that doesn’t get his supposed “news” from CNN MSNBC or fox. The truth is sooooo ez to find. Type “suddenly died” on any search engine for starters.

        2. Don’t call someone an idiot until you can use the correct “you’re”. You make yourself look like a moron.

      1. Avatar Just STOP!!! YOU are spreading DISEASE with your ignorance and disrespect for the deceased and his grieving family! Instead of waiting for detail from family IF they choose to share YOU CHOOSE TO START RUMORS!! says:

        YOUR DISRESPECT FOR DECEASED AND FAMILY IS PATHETIC! WHY THE NEED TO SPREAD RUMORS??

        1. Hey dump truck all he was saying was you shouldn’t believe everything you see on the news. It’s so easy to believe what you see most don’t second guess it. Just think for yourself and ask questions to get to the truth. My heart goes out to his family and may God bless his soul.

      2. Another victim of the jab.

        Sad… yet none of you ignorant idiots will ever admit the truth that the vax killed this young man.

        Thanks liberal chinese sympathizers

        1. It doesn’t matter what took him away have some respect for his honor an friends and family, I’m 60 years old and I got the same vaccination I’m still kicking and racing, ? your a complete idiot with no class or respect,..

      1. That’s because none of that information has been released. I guess Racer X, Dirt Bike Mag and Gate Drop are all the worst writers too since they also don’t share what the cause of death is.

    1. I know . No one said what had happened to him …at least tell us…I send my condolences to the family and loved ones

  2. So sorry for your loss. Difficult to believe this could happen to someone this young and this talented. I’m at a loss as for why he died.

    1. US supercross and motocross star Jeff Alessi has died at the age of 34 as a result of a sudden massive heart attack.

      1. I am inclined to believe that the earlier comment was right. 34-year-olds don’t die of heart attacks out of nowhere. not until now…. To race pro motocross This guy had incredible cardio. His profession proves that he had a healthy heart. Until it was poisoned with heavy metals. So sad.

        1. It probably was covid vaxx. Many star athletes have died. They will never be able to punish those who did this to the whole world enough to make up for the many they killed

        2. I can almost guarantee it was probably the Monster energy drinks that took his life if I was a family I would look into that because those Monster energy drinks are not good for you

  3. Was it related to the COVID-19 vaccine? Because he is way too young to pass away by natural causes obviously! So young, so sad! I know so many that are sorry that they took the c-19 jab

    1. Enlarged hearts, leg clots, general lethargy are just some of the contraindications they’re seeing with our younger population. Adult Sudden Death Syndrome is their nice way of saying the mRNA has something to do with these untimely deaths.

    2. Rest in peace Brother
      Family should let us know if he did get the jab. We need to spread the word about how our government lied to us.

    1. Happening way too often..strong young healthy athletes…heart attacks? Why? Many believe the jab thinkens the blood and when pushed to pump faster it can’t because of the vaccine. Scary times!!! Sad for so many families…

  4. Alot of young athletes that have recieved the VAXX are suffering the same fate. Nobody wants to talk about it though.

  5. Why does so many people use the Covid excuse when they can’t get a answer!!! Those shots aren’t killing people.Peoples lifestyle & choices are killing people…Now then……My sincere grief goes out to the Alessi family They are a class act & it saddens me knowing the hurt they are going thru…RIP Jeff

    1. I don’t know what really happened to Jeff, I’m not going to talk about something I don’t know. It’s also none of our business. However, you might want to research Covid vaccine side effects and mortality stats. I say this as a physician.

    2. It couldn’t be because deaths are up 40% in people aged 18-59 since the shots came out, could it? Everyday now we hear about a young athlete dying of a heart attack where we used to hear of maybe one a year.

  6. Might of been the monster energy drinks that gave him a heart attack . I’m saying this because a few years back I was drinking so many of them . That I ended up in the hospital . My doctor asked me if I drank energy drinks and I said yes. how many monsters per day he asked I said 4 on a 12 hour shift from work . He said wow you wanna kill yourself . I almost had a heart attack stopped drinking energy drinks

  7. Sorry for your loss and I agree that there’s something about the covid shot and all the young people dieing lately it’s ridiculous and sad.

  8. Unfortunately he died from what most are dying from now.. Heroin/ Fentanyl overdose.. it’s destroying our people . .. as James Brown said in his music – another one bows down to King Heroin . RIP ?

  9. Way too young… I find a lot of the comments regarding how he died….Hilarious.. COVID shot… really
    ??? I must be old.. we use to go straight to drugs or racing accident or health problems that he just found out about. I any case 34 is way too young and my thought and prayers go out to his family and friends.

    1. Debbie. Wake up. I know you want to believe that the clot shot is 100% safe and effective because you took it but it’s not. Do your homework on excess deaths since this poison was injected into tens of millions of people. Used to be when someone died the cause was listed. Now it’s described as “passed away”. Why is it so taboo to ask the question?

  10. My condolences to his loved ones. People don’t die typically from heart attacks at 34 till now. Those clot shots have caused myocarditis in athletes in his age group. Now 11 % greater risk of it. Perfectly healthy people don’t just drop dead. Those with health problems and years of it do. Sad situation. God bless him.

  11. I don’t know how he died, but it certainly isn’t natural for a 34 year old in terrific shape as all mxers are to die of a massive heart attack. Rumors I’ve heard are suicide. But honestly don’t know. RIP Jeff and God bless the Alessi family.

  12. Yeah. Massive numbers of vaccinated test subjects have passed from heart attacks. So that’s facts.
    Th only idiots are walking around with their eyes wide shut talking trash with nothing but specifically altered and chosen statistics with no real knowledge of the topic

  13. Rest in piece Jeff. I have nothing but respect for the Alessi family. You will be missed. Mike, keep riding in his memory.

  14. I knew both Jeff and Mike in Simi Valley during the 1990’s. They would visit their Dad, Tony, during the Day at his work. Great Kids… ride on, Jeff… we will miss you!

  15. My sincerest condolences to the Alessi family, this is truly a tragic loss of life, at such a young age.
    A man that lived what he loved to the fullest, thriving at the top of his game, an incredible sportsman to the highest degree!
    You have my sympathy and respect. R.I.P

  16. i’d call , but what its worth without a jury i want to suggest to picture the individual of intensesense what to avoid : joe gibbs not pre – Oedipal

  17. Jeff was a solid young man who was taken from us way too soon. From all of us in North Florida we send our most sincere condolences to the entire Alessi family. I’m not saying Jeff was perfect, especially in his younger days. He was fast AF and he loved the sport of motocross. He could go to any local track and pretty much Smoke 99.9% of the people’s on the track with little to no effort. But still he was willing to help those around him in the pits. I’ve seen him go out of his way to help strangers countless times. That’s a rare quality for somebody with that kind of talent. I mean let’s be realistic if you were that fast, it would be pretty hard not to be a dick. But Jeff grew out of that shit and got real about what was important in life. Brother, I’m deeply saddened you’re no longer with us. But I’m quite positive you’re somewhere up there ripping shit up ✊ Braaap
    One last thing, for those who believe this is the appropriate venue to stand on your soapbox and rattle off your theories about Covid and vaccinations it’s disrespectful and it speaks volumes of your character. I respect your right to believe what you wish, I might even agree with it. But this isn’t the time or the place. Seriously, pull your head out of your ass and show some respect

  18. Revised Comments;
    Jeff was a solid young man who was taken from us way too soon. All of us in North Florida we send our most sincere condolences to the entire Alessi family. I’m not saying Jeff was perfect, especially in his younger days. He was fast and furious and he loved the sport of motocross. He could go to any local track and pretty much Smoke 99.9% of the people’s on the track with little to no effort. But Jeff was willing to help those around him in the pits. I’ve seen him go out of his way to help strangers countless times. That’s a rare quality for somebody with that kind of talent. I mean let’s be realistic if you were that fast, it would be pretty hard not to be dismissive. But Jeff grew out his youthful indiscretions and got real about what was important in life. Brother, I’m deeply saddened you’re no longer with us Jeff. But I’m quite positive you’re somewhere up there ripping it up ✊ Braaap One last thing, for those who believe this is the appropriate venue to stand on your soapbox and rattle off your theories about Covid and vaccinations please stop. It’s so disrespectful and it speaks volumes. I respect people’s right to believe in whatever they wish, this is American. I might even agree with it. But this isn’t the time or the place. Seriously, show some respect ✊
