Alex Marquez racing accident; motorcycle damage extreme
- Thread starter BusyLittleShop

You do realize the speed he was going at the time he went off track after he hit Acosta because of Acosta's technical problem, correct?
Major accidents typically happen in corners when the speed is lower, this was at 150 mph as an estimate. The bike did not slide off into the gravel, it was straight ahead and extremely fast when it went off track. Marquez bike hit Acosta with such force, Acosta's rear tire was burst from the impact of wheel to wheel.
Stiffest part does not equal the strongest part. Shear strength makes a great difference. Triples are meant to handle fore and aft loads, not side loads when a bike is going 150 mph cartwheeling through the air. Very much like different grades of bolts have different stiffness. Stiffer bolts can fail before lower grade bolts that have a bit of give depending on the situation/scenario the bolts are exposed to.

It was a very nasty crash for sure. Unfortunately the racers are not anticipating a power loss.

A Rapid Unscheduled Disassembly. Terrible.
Power loss? Can you clarify?
The bike in front of Marquez suffered a sudden power loss and they were riding so close, as they do, that Marquez ran into the back of him. Racers place tremendous faith in other competitors, can you imaging driving at 150mph only a few feet from the vehicle in front.

See post #7
While I did not see this particular race I have seen enough accidents on the track due to sudden slowing from other competitors.
Yes, in the club racing I've done, you are often drafting the bike in front of you, to hopefully get close enough to pass or out-brake the rider in front of you coming into the next turn. The track I've ridden the most you are in the 180+ mph range on the front straight, coming into the braking zone. The MotoGP riders and their bikes are in a different league to me and most who have raced at the club level, but the idea is the same.
Yes, the biker just before him was raising his hand to indicate that he's slowing down or has an emergency.
A friend of mine rear ended another guy (friend of his) who was slower on the track and was planning to go in the pit. My friend walked away but the guy who got rear ended spend 6 months or more on crutches and I think started to limp after that. I think he injured his pelvis.
He is already out of the hospital. He got extremely lucky.

Too little too late!! IMO, there was no time to react.

Those 'GP NATION' videos are terrible. About 30 seconds of information dragged out to 10+ minutes of AI-generated filler. Do YouTube channels get paid by the minute now?

The only legitimate source of information regarding Moto GP is here:
https://www.motogp.com/en/news/2026/05/17/alex-marquez-injury-update-after-catalan-gp-crash/1069118
Get ready to open up your wallet if you want to see the actual racing though.
IMO Moto GP is like a go cart race when you compare it to Isle of Man TT. When you see the likes of Michael Dunlop, Peter Hickman or the Crowe brothers blasting through a course then you will understand.
I've been there. The guys you mentioned are no doubt skilled. MotoGP riders are on another level. Those guys who ride in the Irish Roadracing series, have said the same.
