Just fast forward to the end to see the crash.

I hope the rider is ok.

That Bimota looks very nice.

 

[strega]

target fixation, then too much front brake?
given how much they cross the yellow line, they're lucky...

 

[Enchanter]

Both of them were taking crappy lines through out the entire video (early apexing leads to running wide). It finally caught up with the Bimota rider.

Jesus. Trading paint on public roads is never a good idea.

 

[BaSSiUsMaXiMouS]

hes lucky he hit that barrier or he woulda went for a long fall

 

[Shaggy]

Get him off that ledge! If he passes out he's going to tumble down that hill!

Funny, my wife just walked in right as the crash happend, and thats the first thing she said...........

Imedeatly followed by "No kids for him then" :teeth

negative......lines were plenty good enough for 10mph less corner speed......cause of crash? easy......going waaaaaaaay too big on public roads

I observed a few things

1. going track speeds on the street and using both lanes but not all the time

2. target fixation

3. bad line, went in too early.

You could see he went turned in too early and then he wanted to bring the bike back up but realized it the turn wasn't finished, started leaning in again and then target fixated on the rail. Oh and did you hear? He broke his back 2 months earlier

Sure, I can analyze that one easy: Even Italians with leathers and expensive bikes can qualify for Squid status. :teeth

Crazy ass shit for the streets period!!!
Take that shit to the track..

Exactly. Man, that poor Bimota. Glad the guy's OK though. Was that from one of those British bike mags?

Analyze this crash.
He ran out of skill.

Huh? Yes they were going too fast for public roads, but I stand by my original statement that they were all over the road. Surviving hauling ass on public roads damn near requires late apex's. He ran wide due to a combination of speed and turning in too early.

heh, fast bike guys. that's an old video.

 

[slydrite]

uhhhhh......whatever.....the idea is that a later apex, requires a later and therefore slower turn in SPEED............they were turning in early in many corners, because they were going way too fast

again, what caused the crash was speed, not line, if one takes that exact same line with just a few less MPH, they don't run wide and crash.....

IOW, one is cause and the other is effect


*edited for confusing myself and others for leaving out the word "speed" after "slower turn in"*

 

[Ratters]

heh, fast bike guys. that's an old video.

That's what I thought. They had the video of going to the motogp too. And crashed in that one too. You'd think they'd learn.

hm...when i late apex, i'm turning in faster than i am when i'm early apexing.

That's what I thought. They had the video of going to the motogp too. And crashed in that one too. You'd think they'd learn.

it's not a proper fast bikes video unless someone crashes

*sigh*

this is the problem with this site and the web in general.....so much misinformation....

I shouldn't even bother and normally I don't, but here ya go:

the max corner speed for ANY vehicle on wheels can be mathematically determined this way:

(V = R)squared, V represents velocity and R represents radius IOW, the bigger the radius, the faster you can go, that's why drag racers only go straight.....the full formula is actually slightly more complex and takes into account the grip of the tires and surface and other shite, but for simplicity's sake, let's leave it at that

BY DEFENITION THEN, an early turn in gives you a bigger radius from turn in to apex, after that it could be a problem depending on how one deals with it....

a true later turn in is a SMALLER RADIUS TURN, from turn in to apex, but then you get to stand the bike up sooner, and therefore get to full throttle sooner, IOW, you sacrifice entry speed for superior exit speed......

if you think I don't know WTF I'm talking about, then WHAT EXACTLY IS THE POINT of a late apex in terms of speed and lap time?!?!!?

I'll tell you, it's called slow in, fast out, that's the point of a late apex

Neal, a late apex requires a quicker "turn in" than an early apex. it's the reason most noobs early apex...they can't get the bike leaned over quick enough so they start the turn earlier.

An early apex doesn't mean a bigger arc....quite the opposite. When you early apex, you end up pointed the wrong way at the end of the turn and have now effectively turned your constant radius turn into a decreasing radius.

Late apexing does the opposite...you wait...wait...then turn in quick and it turns your corner into an increasing radius arc...which is faster and safer.
