tri z max vertical drop!?

[XFR_Dozer]

lol so by that logic an airplane could be dropped at 30,000 feet right to earth and it would land the same as it normally would.

I don't think a trike generates lift when it is moving forward!

200xman took the words outta my mouth lol
,,,i have an idea for another topic

[XFR_Dozer]

im not physics professor ,but in a real world application trajectory has a direct effect on the force of landing impacts. on most jumps the farther you go the higher you go so the landing trajectory is somewhat similar but on a drop off you can flatten out that trajectory, the farther you jump lessening the impact. The flatter the flight path the more energy is diffused into forward motion upon landing. We agree to disagree on this one.

[Red Rider]

Sounds like TriZ_Jim & the Xman have some aviation knowledge.

[XFR_Dozer]

hmm

[Red Rider]

I understand where you're coming from Dozer. I think you said it best though, "let's just agree to disagree."

lol... i am not over educated but that makes good sense to me ...the farther out you go ( trajectory)..the less the impact....i concur

[Red Rider]

On earth, the force of gravity is pretty much constant, and falling objects accellerate towards mother earth at the same rate, which is roughly 32ft/sec. If you jump straight down off of a cliff, the small area that you land in will absorb all of the impact, and you'll probably leave a dent in the ground. Now, if you're moving forward when you jump off of the same cliff, a larger area will now absorb the same impact, and you probably won't leave a dent in the ground. What I'm trying to say is, regardless of the trajectory, the bike is subject to the same impact. By adding some trajectory into the equation, all you're lessening is the impact in a localized area which is better for mother earth not you, and that will make the BLM, Greenpeace, & tree-huggers everywhere happy. Remember my motto, "Adding trajectory to your jumps, saves the earth from nasty bumps!"

Red Rider, You're a rapper too??? Damn!!! I remember the Dirt Wheels article your're talking about and you never duplicated their 8' drop off, you did 4' max. If you recollect though, I safely landed a 12' drop off, only bent my handlebars and my shorts cleaned right up. But your buddies Tecrappy didn't fair so well.

[YAMAHA_Jim]

With all of that said, I will add this.
The wheels and susp are what absorb the landing.From a straight drop the wheels and shocks dont fair too well(say 10'),,,,,now drive off a 10' cliff at 30-40 mph(landing on flat ground)the wheels and susp absorb the landing quite well. At 80 mph the landing would still be rough but alot smoother.
The same rules apply to high speed car crashes,when people get ejected they just bounce and skip on the ground,,,,which makes for some good road rash. Whats bad is when you get ejected at 75mph and your body goes THUD against an inanimate object.

[Red Rider]

Fo' sheezy ma' neezy. Mr. Sandman, the 12 footer, that you accidently rode off of, must have done some damage to your ability to remember facts correctly because my buddy wasn't riding a Tecate back in those days. Can't you remember how his front tire blew out on his '84 250R, with a 300 big-bore kit, when he bailed out? Also, while it is true that I started out on the 4' dropoffs, I eventually worked my way up to the 8 footers.

TriZ-Jim, let me see if I understand this correctly? Using your logic, I would fare better by being ejected from a car going 80 mph, than if I jumped out of that same car while it was parked.

[Mr. Sandman]

RR, you're right, TW was on the '84 300R. It's still funny as hell though, but I still don't remember seeing you do any 8 footers. You may be a legend in your own mind!

And to better understand what Tri-Z Jimis trying to say, change being ejected from a car to being ejected from your R while riding a wheelie down the street and losing it. DOH!

[XFR_Dozer]

i believe jim is referring to the difference of sliding or rolling to lessen an impact or being a bug splatting on a windshield. if you would rather roll off a drop off as dead weight be my guest. i think id take another approach.
