90 degrees at 40mph...no way...try about 15-20mph...any faster and you won't make the turn...
have one up my way if you want to slam into the bottom-side of a bridge...yikes!!

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

That's actually the proper way to enter a corner for most vehicles. It's also why hard braking in a straight line before your entry is so critical to achieving the highest exit speed. When you do it right, it feels like dancing, not rough or forceful at all; almost peaceful, not scary or thrilling.
This shows two distinct lines for the same constant-radius turn.
The solid line shows the geometric line around the turn, while the broken line shows a late-apex turn. Following the geometric line, "A" marks the entrance point, "C" marks the apex, and "E" marks the exit of the turn. Since this line uses a constant turning force around the entire turn, the speed the vehicle travels though the entire turn (From A to C to E) is the same. If the speed is exceeded at all, the tires will lose traction, and the vehicle will slide off the line.
The late-apex line is a different approach to taking a turn. "B" denotes the turn in point, "D" marks the apex (Which is later in the turn than the geometric line, hence the name “late-apex” turn.—), and "F" marks the exit. In this case, however, once the apex is reached, the angle of the front wheels is significantly reduced, thus the vehicle can begin accelerating sooner without the fear of sliding off the line.
Which line is better? Both have their perks, but for most daily drivers, the late-apex line is usually the best. One reason is that street-driven vehicles can brake much faster than they can accelerate, so braking time is minimized and acceleration time is maximized. Although the entrance to the late-apex line is slower than the geometric line, because the initial turn in is harsher/sharper, by the time the apex is reached on the late-apex line, the vehicle can begin accelerating, thus maximizing the amount of time on the throttle. In this case, at point "C" the vehicle running the geometric line is traveling faster, but point "D" marks where the late-apexing vehicle can begin to increase the throttle, whereas the geometric-apexing vehicle must wait until point "E". By the time both vehicles reach point "F", the vehicle that took the late-apex will be traveling significantly faster than the other vehicle, and that speed will be carried to the next turn.
The late-apex also gives you many more options once you reach your apex. You can remain slow at that point if there's something in the road or traffic ahead. If something goes wrong it generally happens at a lower speed as well. It's also easier to actually execute and requires less "perfection".
If you hit the corners right the nanny will sleep peacefully throughout the turn and you'll achieve speeds significantly greater than what you would ever expect.

And that's why everyone else does the caring for you. I hope you never forget what an inspiration you are to others.

Bob did you know that spiders have multiple spinerettes and the silk from each has different tensile strength to suit a particular purpose? For exampe, making the center of the web as compared to the outside of the web or wrapping its prey or a spiders safety line.
Sorry for getting off the cornering topic.
I know a fella who has arachnophobia ...... I saw it first hand and his reaction was pure terror.:yikes: I am completely and utterly terrifed of arachnids... But your artwork is still great! :thumbup:

His reaction was probably MILD compared to mine.. :shocked:
Enough of this or I'm going to have to go home and puke!

This is gettin' funny...but...we each have our own styles because of our individual physical builds....a six foot ryder will corner differently from a five footer.
There are a few great rules that will, if you ignore them, come to visit you in the emergency room.
Do yer brakin and gear shiftin' in a straight line....wide entrance...pick yer apex and anchor yer body with the inside knee and remember if you can't stop within yer cornering visibility you could be dryving up an inclined plane twisted around a vertical axis.
Honestly, I'd love to see Bob or Setho in a frisky mood on a twisty road...!!!!

As there is always a cost versus function beneifit to add ons there is also a performance versus experience benefit with performance upgrades. Only the rider can truly (if they are honest with themselves) determine if that new wiz bang racer ready performance upgrade is either needed to enhance the way they ride or to just impress their buds. I am a point a to point b rider at pretty much the speed limit plus or minus 10 mph. Other than a Hindle muffler (cause I like the sound) anything else would be a waste for me. Now Doc on the other hand is probably at the outer edge of experience and the need for performance enhancements, no not that kind, the motorcycle kind!

When it comes to cornering, the forces applied by the rider are based on the centripetal/centrifugal association. The movement has to be similar no matter what the size of the rider is. It's the forces that determine the necessary lean/tuck to keep the bike from waffling and perhaps lifting a wheel...

I disagree with the effect of a the size of the rider, if I ride against jim I can see where he shifts his weight and he gets a different result than me being 75 lbs lighter and not a mobile because of my handicrappness.
There is some good ways for me that work but not for others because of the same non mobile issue. Full humans have a big advantage over me in that sense, not that I can't do well, just have to do it with less.
Digging thru my videos I forgot I had this one with the wheelchair mount camera angle, its not a super twisty road but it show how much i move compared to other people. There are other videos where the go cam is on my head and you will see me shift back into the center of the bike because my butt slid one way or the other, which costs me time.

practice practice practice we can tell you lots of stuff but you must try what works for you
i personally when alone i think of like a snow mobile ans almost slide my self off the seat to Conner i find that works great at high speed just start slow good luck
Yes> 100% AGREE !!!!!!!

Doc is fast. I had the opportunity to ride the twisties all out with him. Great ride!
I've not had the same chance with the rest (or you either SethO) so I'll just take your word for it.
I did find that Forrest isn't all that fast when he is towing a trailer! But I would never challange his ditch jumping expertise!

The fastest guy I ever rode with told me you take the posted, double it and add your ball size. Again if you think you are safer on a spyder, you are lying to yourself, you will lose to a Prius with one extra tire bouncing down the road.
So... being female, I use my boob size?:roflblack: Gotta make sure I get the formula right!
And now ya got me imagining racing my Spyder against my Prius...
I love ryding with Ltownblue, but we do ryde differently. I'm 5'3" and rather round, while he's taller and very muscular. He can get his butt off the bike to shift it over, but I don't have as much leg to work with, and a much bigger butt to lift, lol! But I assume we both apply similar principles to carving the curves; there are some things that you just can't get around. My basic philosophy is to lean enough to keep my butt on the bike and the bike on the road! Blue's kind enough not to leave me in the dust, thank goodness. I can't express enough appreciation for that guy.
As the firstborn, I'm more timid; my sister Catniption is much more adventurous, and always has been. There's something to that philosophy!
On another note, I would love to ryde with you or Doc sometime, simply because you guys are legends. Yeah, you guys would make me look like I am in reverse, but it'd be fun to watch ya for as long as I could still see ya. :bowdown:
Nose over knuckle. Gotta remember that. :thumbup:

Physics Question
I know it helps to lean to the inside in the corners (comes natural after riding 2-wheelers anyway, I like to brace my outside leg and slide my butt to the inside), but how does this stop the wheel from coming off the ground? It seems that moving more weight to the inside would make the outside more likely to come up not less. What am I missing here?
