What was that truck doing on the track and where were all the other cars? This is a bit different to Formula 1, is it all about how big a bang you can make with one car and a crazy driver?


Honestly, it's all about turning left. No joke.
Maybe a little about managing your fuel too. Ocassionally it's about choosing whether to go high or low into a turn. Other than that...left turns.

Terrifying motorcycle crash at the Daytona 200

MaxWilder says...

>> ^therealblankman:

>> ^MaxWilder:
Interesting, but I wouldn't say terrifying. At least not to the viewer. The ones I call terrifying are when the riders are doing cartwheels and more bikes are plowing into them. That's what I expected from the title.

Well, I'm a rider and the thought of going over my handlebars at over 170 miles per hour terrifies me. I'll be sure and ask Westby and Knapp to next time make sure their crash is more spectacular for your benefit.


Hey, I'm just throwing out an opinion here, as a viewer. Those guys look like they're sliding on ice, which is not very terrifying to watch.

Much closer to "terrifying":

Greatest Racing Motorcycle ever: Britten V1000

>> ^cybrbeast:
Why did the technology die with him? Surely more could be built?


One person with extraordinary vision, coupled with technological know-how, engineering brilliance and the ability to get his hands dirty and plain-and-simple build what he imagines is a rare thing.

In the case of the Britten bike, this is a partial list of what made his bike special:

1) Partial girder-link front suspension with adjustable anti-dive properties.
-fork-type suspensions compress under braking and extend during acceleration, changing the geometry and handling characteristics of the machine quite drastically during the different driving modes. Britten's suspension design allowed him to control pretty much all variables of suspension geometry under changing load, making the bike behave however the rider wished.
- The rear suspension, while perhaps not as revolutionary, was a beautiful piece. It was essentially a carbon-fibre banana swing-arm with a linkage to the adjustable shock/spring assembly. If you look at the bike you'll see that there's no spring/shock assembly near the rear suspension, rather note the spring/shock assembly directly behind the front wheel- this is for the rear suspension! The front shock assembly is hidden in the front suspension linkage and cowling.

2) The engine itself was a stressed-member.
-While certainly not unheard of, Britten took the concept to an extreme, essentially eliminating the frame from the motorcycle. The front and rear suspensions essentially bolted directly to the engine, thus saving many kilos over contemporary designs. Take a look at any current MotoGP or Superbike- most use the engine as a partial stressed-member, but they all have frame members linking the engine, steering heads and seat-assemblies. Britten really only had a vestigial sub-frame for the rider's seat.

3) Well-controlled aerodynamics and fully-ducted cooling system
-Britten paid close attention to airflow over, around and through his bike. Look how cleanly the rider's body tucks into the bodywork. He paid close attention to details, notice how clean the entire assembly is- no exposed wiring, nothing dangling into the airflow, that incredibly sleek rear swing-arm and rear tire hugger. This keeps the airflow smooth and un-disturbed. Motorcycles aren't terribly aerodynamic machines in the first place, but a wise man once said God is in the details.
-The engine itself is a water cooled design, but where's the radiator? It's in a fully-sealed duct directly beneath the rider's seat. High-pressure air is inlet from the front of the bike, through the radiator and is exhausted into the low pressure area beneath the rider and above/ahead of the rear wheel. Greater cooling equals higher power potential.

4) The motor
- 999cc 60 degree V-Twin, belt-driven DOHC design, twin injectors per cylinder, sophisticated electronic ignition, hand-made carbon fibre velocity stacks, wet sump. The motor was designed to breathe hard, pumping out torque and horsepower (166 hp @ 11800 rpm- not sure about the torque figures), and run cool and reliably under racing conditions. Nothing here that any other manufacturer couldn't have figured out on their own, but Britten had the insight and the will to make the best motor in the world at the time. The 60 degree configuration was, I assume chosen for packaging reasons. Normally this configuration would have bad primary balance characteristics, but Britten engineered his to such tight tolerances that the engine ran smoothly right up to redline (12500 rpm) without using a balance shaft.
I'll also point out here that Britten wasn't above using someone else's part if it was better than he could make himself- the gearbox was from a Suzuki superbike, and the cylinder liners and voltage regulator (both of which failed at the Daytona race in '92- the latter costing Britten the win) were from Ducati.

5) Carbon Fibre
- While Carbon Fibre had been around for 2 decades or so at this point, nobody had used it so extensively. Britten used the material for bodywork, wheels, engine parts, suspension girders and the rear swing-arm. There is still no other bike, not even the current Ducati Desmosedici MotoGP bike, that uses so much of this exotic material. The stuff then, as it is now, was hugely expensive and challenging to engineer for different applications. Britten made everything himself, in his garage, figuring it out as he went. This kept the total weight of the bike to a hugely impressive 138 kg.

Keep in mind that he did all of the above in 1991 and 1992, with the help of several neighbors and one part-time machinist, in his backyard shed! He made the bodywork by hand, using a wire frame and hot melt glue, crafting the wind-cheating shape and cooling ducting purely by eye. He cast the aluminum engine parts himself, heat-treating them in his wife's pottery kiln, and cooling the heat-treated parts with water from his swimming pool!

Ducati, Honda, Kawasaki, Suzuki... any one of these manufactures could today reproduce and expand on what Britten accomplished almost single-handedly. None of them will- there's too much at stake for them. It's far safer to stick with the tried-and-true, making small evolutionary changes over the years. A true visionary achiever (to coin a term) like Britten comes along only every once in a great while.

I suppose that this is what was really lost when John Britten died... vision, engineering acuity, hands-on knowledge, and pure will. Touched with a little craziness.

Comment of the Year (Sift Talk Post)

One of my personal favorites, at four votes; the story of Swampgirl and the Angel of Mercy, Barry Gibb...

>> ^swampgirl:
Barry Gibb almost hit me with his car once.
It was the summer of 79, I was about 11 I think. I was vacationing in Daytona Beach with relatives. We swam all day, everyday. It could get a little dangerous running between the cars on the way in and out the water. You may [not] be able to now, but back then you could drive on the beach.
My cousins had left the water and were almost back to the hotel. I on the other hand was trailing behind.
Running as fast as I could to catch up, I almost ran smack into an oncoming yellow Corvette. I tripped on my float too and fell flat on my face. I got up and looked at the driver. Barry Gibb.
He was there, feathered winged hair-do and everything! Ok, he had dark glasses, but that didn't matter damnit.
I gaped for about 5 seconds, then ran back and told everyone. They laughed. Why didn't I speak to him and get his autograph or something? Duh.
I don't know, I was just a stupid kid. It was him though.


Epic.

my favorite was when they covered a story about a rapist-possible murderer in Daytona and the visuals were T&A over and over. Jon Stewart even showed that one... it was hilariously appalling.
