- Video of my crash at the TT Circuit of Assen. The rear wheel loses traction, skids, and then suddenly regains traction, creating a large torque which flips me head first off the bike and on the tarmac.
Bike: Honda CBR600F4

You were doing great before the crash, awesome riding ! I hope you still ride, dont let that accident bring you down !
Antoine Morin-Prévost Of course I'm still riding :)
I have never been on a track before so please excuse me for being blunt. It seemed to me like you had some supension problems, especially while accelerating coming out of the curve. Is it fair to ask if you were in some way nervous during that ride?
@@michor10 my ignorant perception is that the front shocks were compressed right before he gave it a sudden squeeze at the gas, rear wheel wasn't loaded enough. That's on hindsight of course, I might as well fallen off.
11 yrs old footage found me. You can hear the throttle open at 1:57 while still leaned over. That is the real reason the rear tire lost grip.
Thanks for sharing budd. Depending on you tire/ surface condition, you had too much gas. Early slide detection is the key... Hold the throttle and pick the bike up by pulling on the inside handle bar. This will bring the bike into the slide....it sound like crazy thing to do, especially if dont have much road on the outside but its one of the few means to recover from the slide.
Pulling or pushing?
jackie moon hes saying to just have the bike fall over altogether and bring it into a slide. It’s still a bad crash if you don’t have the right abrasion resistant gear, but it at least won’t be as bad as launching you over the handlebars
I did one of these last night on a cruiser. I took a corner too fast, tried to straighten out a bit and slow down. I obviously didn't' straight out enough and braked too much because I locked up the rear and fishtailed hard. high-siding me off the bike. we both slid a good 4 meters. I mostly landed on my hands and knees then belly slide to a stop. I had a helmet, jacket, gloves, boots and pants and they ALL got used. Be careful out there ride safe! Wear Gear!!
Biggest thing is to not cut the throttle suddenly and/or to not stab the brakes. You need to accelerate through the turn while traveling in not such a sharp angle. Ride safe and keep wearing that gear
poor Argentinian Kid, lack of experience brought him to such situation. But as far I can tell, there`s nothing you can do in such circunstances. RIP Lolo.
and then... there is only the low-oil-pressure-warning-light..
Thanks for posting this & good to hear you are ok. Viewing it in normal speed, my first thought was that you were on the throttle early, too early. Good to hear your analysis, mistakes can keep us alive if we learn from them.
Congrats on Fortnine featuring your video !
Always good! Where can I find that?
@@slimmerik1 Fortnine - Motorcycle Riders - Your Throttle Grip is Wrong
i dont see why some people disliked the vid
Thanks! Me neither:)
Maybe they want more spesific explaination such as how the rear suspension reaction about too, maybe like animation or presentation. . .but this is nice info
I didn't click "dislike", but one thing that I didn't like was that it took nearly half of the video just to get to the accident. That wasn't needed, and it was boring. Just get to the point.
Why are so many saying to close the throttle when this happens , all the safety sources I read talk about always keeping throttle applied around a corner to maintain traction. Not hitting it hard, but not completely letting off of it, more like feathering it, just a little something.
Pro Tip: Get that ignition key tethered to the bike!
If you had of gone to the outside more right after your early apex it might have been avoidable. I think you were trying to be nice to the guy you just passed by not cutting him off.
Legend...for sharing...
Summary: bike loses traction in corner and suddenly gains it again and the bike tips over( highsiding) or the bike loses traction slides, and never gains the traction back (low siding) correct me if I’m wrong
Brett the Standoff king yes, you’re right
Question: why the rear tire should lose traction while cornering
@@rashigupta5995 I think by full rear tire breaking
nice dirt shot . I'm glad you explained that ill make sure to wear goggles so that i don't get dirt in my eyes. thank you.
You have a full face helmet you don't need goggles 🤣😂
I have experienced this too,broke my left bar, left footpeg,and all other left parts of the bike.
such a shame for that wind shield. it was sparkling clean. :)
@Slimmerik, is there anything you could have done to recover from the loss of traction or is the torque too great to overcome, once the rear wheel regains traction?
There’s no way. That bar snapped
Sorry man. Must have hurt loads. I had a lowside crash three days ago and just figured out what made it happen. Panic / hard braking with the front lever. Accidents happen so fast leaving almost no time for us to react.
+Peter Githu no, it's because you had too much lean angle w/ the wrong configuration during certain conditions
To surpass the rider you cut the curve, realized that you had the wrong trajectory and tried to increase the throttle before the apex to compensate, but it was too much for the rear
Why was it the wrong trajectory can you explain. I believe the ideal was to go to outside of the turn which he couldn't.
Any idea why you lost traction? Too aggressive on throttle? The other turns looked like you were pushing the envelope but pulled them off flawless.
Yes the feeling with the bike was great, but probably a little too early and aggressive on the gas...
+Slimmerik I raced superbikes for a few years in the 80sA very ambitious fist full of throttle there IMONice try though ;-)High sides hurt so fortunate you walked from it.
+ally vega too much lean angle and bike power for the tires to remain stuck in 1:1 rate on the road
solution is to lessen the lean angle, get a bike w/ less power or less throttle, get stickier tires or find another combination from those 3 important variables
Safest way is to always be at a maximum of 80% maximum potential at all times then you can never bust anything. If you want more then you increase the maximum potential ceiling limit.
+Anthony Abelardo Thanks for your comment. But do you know the expression "kicking in an open door"?
Slimmerik no
Where are you sitting in the seat? I highsided yesterday walked away okish but trying to figure out everything that I did wrong. Our crashes are near identical.
It was in that moment, that SlimmerK knew he'd fucked up...
(I've luckily had 4 rear tyre slides and managed to save them all by blind luck alone, all of them required a change of leathers shortly after.)
Classic track day scenario. Got spooked into a bad decision.
Yeah, I broke my back doing that 35 years ago. Don't do that. Trust me.
were you wearing a back protector?
Don't do what exactly? Why did the rear tire loose traction
Ik ben een beginneling met een motor vol elektronica. 8 van de 10 keer dat ik uit een bocht kom, flashen de led lichten op mijn dashbord, de tractiecontrole kwam in werking. Die TC staat meestal op max. Ik had gedacht om die wat veel minder te zetten, maar na het bekijken van uw vdo, misschien TC toch op max. laten?
Pretty nice riding before the crash. Hope you were alright and the bike was salvageable.
Thanks. The bike has been rebuild and even crashed again..;)
At least it's being raced and not garaged!
at the precise moment when the rear tire started to slide,had you immediately shut the throtle, maybe it could have been avoided, am I right???
I don't think it is that simple. When you shut the throttle, the tire regains traction and that is exactly what happens in a highsider and flips you over de bike.
@@slimmerik1 As he said, you should have shut down the throtle. You can see that rev is doubled because back tire lost traction. Then you cut down the throtle and it regained traction (rev decreases slowly) until it gained enough traction to throw you out.
I don't think you could totally avoid accident by not shutting down the gas but maybe you would have had a smoother landing :)
Ouch! Maar je hebt het wel overleefd :) Gekwetst? Motor rijp voor de sloop?
I had one of these today on a bicycle did the ligaments in my left shoulder ,hope you're ok buddy .
ARTHURCBR that can hurt... Also too much power at the rear wheel?;) All is fine again with me. Thanks!
I saved one of these one time by pure luck. Not a fun feeling when your ass isn’t on the seat anymore lol
Alright, this helped me out a bit. I started riding last year in January. I road the equivalent of 4 months on my DR650 including the Tail of the Dragon, Devil's Triangle, and the Skyway. No wrecks luckily. The engine exploded this past St. Patrick's Day and I just got my first street bike, an FZ10. Being that I've only ridden it a week, and my complete lack of experience on such a bike, what advice can you offer me to prevent high and low sides? I ride all year.
Dat was helaas niet mogelijk...;) Maar de CBR is weer opgebouwd en gaat als een speer
could you have done anything to save that loss of traction? I'm a brand new rider and can not really afford all these advance riding classes so I'm trying to learn by other methods. hope you recovered well be safe and greetings from London UK
When the bike is leaned over that much the contact patch is tiny so your traction is very low to begin with. I don't think that anyone can really teach you how to save yourself from a highside but you can do things to avoid it. Like keep the bike as upright as possible. In a turn this is done by properly setting up your body in a correct manner (not twisted but parallel to the bike) BEFORE reaching the turn and before braking and develop good throttle control. Also look where you want to go and keep your arms soft on the bars. My own advice for riding the streets would be to ride at a level you feel comfortable with and always ride at a pace that will allow you to see far enough ahead to avoid mid-turn corrections. Never allow yourself to be cocky on a motorcycle, especially around friends. Also watch "Twist of the Wrist" or get the book by Keith Code. There are valuable lessons to learned there. Practice on streets that you know or if you're serious about riding, try to get some lessons on the track. Enjoy your ride!
Oh, I forgot to mention. The reason highsides happen is BECAUSE the rear tire REGAINS tracktion very quickly, ejecting the rider from the seat. So really, what you want is to bring the bike into a more upright position while keeping the throttle calm. A very difficult (if not impossible for most street riders) thing to do. It all happens so fast that all you can hope for is luck. Avoid leaning the bike far off on the street and learn proper body positioning to take the curve safely with the bike in a more upright position and with good throttle control before the curve, into the curve, and riding out of it.
Let me guess, Michelin Pilot Sport tire?
Tire was pretty worn?
It was a Supercorsa. But it was pretty worn and not enough heat in it.
@@slimmerik1 Cool, did my highside on a worn OEM michelin pilot sport on a gsx750r, but that was a long time ago, however got some flashbacks from your clip :P
Explained f()$@ all.
Motor heeft wat cosmetische schade, maar wordt zeker weer opgebouwd. To be continued...
I couldn't take those turns at 60 kph let along 160..... dayuuumm
Really good riding. Too much throttle too quick. Hard when you are doing it but that is the reality.
Smoother on the throttle. Again, very good riding. I think you were worried about the guy you just passed. Someone said the guy in front of you kicked out too. No way you could see that. On a 72 in screen and zoomed i can't see that. Bs on that comment.
Hi, I am currently working on the development of a new television series for Discovery. We would be interested in including an extract of the above video in our programme and I wonder if you can tell me whether this might be possible? Check your inbox for details, thanks!
What kind of motorcycle is this?Exactly model?Isn`t CBR F4 year 2000?
Yes,sorry,I didn`t see that is specified in description..
Ilea Alin It's a CBR600 F4 from 1999:)
Thanks !:D
if you notice this starting to happen what is your best bet? pull in the clutch so if the tire regains traction you don't suddenly jolt and get thrown from bike?
My best bet is to keep the throttle open, drift through the corner and hope for the best... When you notice the rear wheel starts to slide you don't have time to pull in the clutch. By the time I noticed my rear wheel lost traction, I was already flying in the air:)
Its all about throttle control... Ok its easy to say what you have to do in theory... But when you shut down the throttle, the bike regains traction, and thats the reason you get kicked from your bike... When in doubt, throttle it out :D... But i crashed many times just like you :P
Soms is buiten wat krassen alleen je EGO gekwetst......
Prachtig circuit Assen, toch?
Oprapen en doorgaan, als het kan
assen
wheeeee
Slim idee, je knippers aan de binnenkant, blijven die teminste heel :D
Helaas hebben die het ook niet overleefd;)
Met mn CBR rij ik op straat en circuit. Ik heb uiteindelijk een gescheurde 2e hands kopkuip gekocht en die zet ik er nu op tijdens circuitdagen. Wisselen gaat redelijk eenvoudig.
Need better throttle control....and lean angle
Thanks. Great help...

Happend to me two days ago on my R1 5JJ. I landed on my back! No broken bones but pain everywhere, chest in particular. Bike's handlebar bent, fairings and Akra exhaust severely scratch. A mess.
Glad you are ok, same thing happened to me, very sore chest and shoulders, no broken bones, a very unsettling thing to experience on a motorbike…
