I know we've all talked about this event before but gently caress...I really don't understand how all those crashes happened. I mean all of them are so spectacularly basic failures of riding, on a clear day with a mild curve you can easily see around on bikes that are slow and have good brakes. Is that literally the first day of riding for literally every single one of those people? How can so many be so bad?

Some of the “your first motorcycle” advice is like “who will you be riding with?” and I watch things like this and think, “No one. Ever. Under any circumstances.”

On dry asphalt, my rear wheel lifts long before the front wheel even thinks about locking up.
I can imagine that in corners, it's easier to lock it up because there are also sideways forces at play. I've intentionally tried locking up my front on a straight section of freshly laid (so not yet grippy) asphalt, and in that condition it is pretty easy to do and things go sideways very quickly. Still, you gotta be very deliberate about achieving 100 percent brake force before the weight of the bike has transferred to the front wheel. The lighter the bike, the less inertia and the easier it should be to brake on it.

In any case, my instructor was quite harsh when doing the brake drills. On one terrain, he set us up for doing the brake drills looking out onto the river bank. So if you'd fail really badly, you'd end up in the river. Of course, there was a decent amount of space between the end of the brake drill and the river, so even if you'd just mash only the rear brake in a full on panic, you'd stop in time.
On another terrain, we'd look out onto a plot of unbuild terrain. Both had a pretty effective psychological effect. No one of my group dropped their bike or ended up in the river. I think one overshot into the building lot, but in that case there was not much margin because oh well, you gotta drag your bike out of the sand and that's it.

One of the examinated tests is to brake from 50 to 0km/h in exactly 17m, while shifting down to first, without triggering ABS or heavily modulating brake force. You get about 50cm of leeway in each direction. The other is a full on emergency brake, ABS triggering allowed, no shifting needed but you gotta stop sooner, idk if there are hard distance requirements but somehow i'm thinking of 12m.

On the other hand, on wet asphalt or road paint or leaves or sand or tar snakes, the front wheel locks up far before you can apply enough force to lift the rear. This is why it's so critical to always use both brakes :eng101:

You eventually learn that no matter what is happening around you or how your lizard brain is panicking, you don't just SLAM on the brakes immediately to 100% force. You roll it on, quickly and firmly, and maybe to 95%.

That's the difference between someone who cant figure out how you could ever lock the front on a Harley, and someone who locks the front on a Harley. The former knows how to actually brake, the latter doesn't.

It's like all the boomers who are deathly afraid of using the front brake. You only think its dangerous because you don't know how to use it and dont understand it

Just wanted to reply to this that my crash on the Harley in Poland was by just grabbing a fistful of the front break in panic :v: Kinda sad I didnt get it on video

I can't make out what caused the front to slam down; doesn't look like he hit the rear brake and I wouldn't expect chopping the throttle from the balance point to be that abrupt.

Regardless, fuckin' lol

Seems like every time I can’t easily figure out what causes a crash, the answer is suspension. Dude drops on the seat, loading the rear suspension and then…


Razzled posted:

might have a handbrake that he accidentally grabbed a fist ful of, kind of hard to see anything tho

Sure looks like this. But maybe the bounce was just too much and he wasn’t ready to come down from the balance point and as he started to come down unprepared he came down more and faster.

There's something really fucky going on with that while front end. The wheel looks dented to poo poo, but also like it was warped with a Photoshop smudge tool, and the forks look curved too. Might be light and shadow weirdness, might actually be bent.

As a one time owner of an RD350 with the works, they’re extremely fun bikes. Like, there really isn’t much that is more exciting to actually ride, but man are they hard to live with.

The poweband wobbles up and down on the tachometer based on the temperature of the air that the bike currently resides in

The electrics are 70’s Yamaha, which is to say garbage

They are deceptively tiny. I’m 6’3” and I felt like a circus bear on a tricycle. They are designed for Japanese GP riders.

The power though is extremely addicting, and when it all comes together and works as it should, they are like nothing else.

Before most tracks banned 2-strokes in the naughties you could still see Elsies racing and even occasionally winning in club races. They got grandfathered in to the Juniors class (bike formula, not age range) and with some suspension and chassis mods - and a sufficiently insane rider - they could hold their own against 90s 250 2-strokes and 400 4-strokes, especially at tracks like Cadwell where even the start-finish straight is an off-camber corner.

Yes, and on every single lap of every single race, every single RD rider would traverse every single straight with their hand covering the clutch in preparation for the engine seizing.

I worked on a 76ish RD125 that the owner had installed the battery backwards on. Everything worked normally. Lights, horn, ignition, even the charging system. Only sign of a problem was the battery tender plug had touched the frame somewhere and melted itself.

I'm told by one of those sufficiently insane riders that straights are actually pretty safe for engine detonation - it's corner entrance that's going to kill you, because with premix closed throttle = no oil getting to the engine. Not *normally* a problem for the fairly short amount of time you're braking, but if the engine's going to seize that's the point it's going to do it, and of course that's the most entertaining time for your back wheel to lock up solid.
