why drifting all of a sudden?

why is everyone trying to drift all of a sudden? is this to get through a turn faster or just for a "hey i can drift my dirtbike sideways"

and if it is to get through a turn faster how/why is it faster than squaring a corner off or another means of getting through a corner?

thanks, Ryan

Ryan.

Read the post below, 'Drifting unsuccessfully.'

There is nothing new about drifting or powersliding. It's just another way to get through a corner.

I want to know because I would like to run a TT race some time in the future. It's not drifting. That is what the rice burners call exhibition driving. When you do it for speed, it's flat tracking.

Drifting as a "sport" is the motorsports equivalent to figure skating, as a racing technique it's all part of the game.

Squaring off is usually a bit slower than anything else because you have to come to a complete stop, turn, then regain all your speed again rather than hold your speed through the turn.

I like it, "the motorsports equivalent of figure skating". I'm going to have to steal that quote from you.

I know what drifting as a motorsport is, and i kinda know what flat tracking is but in the past month ive read like 10 threads about "drifting" - sliding through a corner and was wondering why it came up all of a sudden and if it is actualy faster to get through a corner that way or if I wasting my time reading the threads about "drifting" and kept squaring the corner ( I deal with mostly 90-ish degree corners)

it probably has more to do with the situation, and the fact that you can "point and shoot" a two stroke (by fanning the clutch) better than a four stroke (which will destroy a clutch if you try and fan it too much), so if you can drift a corner, keeping the four stroke throttled so you don't risk any "hiccup" when you hammer the throttle for the next obstacle.

it'd also work in certain corners for a two stroke since you might be able to keep the bike in the meat of the powerband. But, if you are banging bars and looking to pass, squaring off the corner to block your opponent might be the better option.

Of course, I'm not a pro, I just stayed at a Holiday Inn Express last night

Little bit of physics.

Thanks XRpredator i was most likely going to stick to squaring the corner anyway just curious.

This post might get nuked but i think its interesting...

So, I read the "drifting unsucsefuly" thread and they said to practice you should go in a circle and keep increasing speed until your back tire starts to slide out then its just a feeling thing so I'm sitting in physics class and my teacher is talking about an unbanked curve and how fast you can go around an unbanked curve with this formula.
Velocity(speed) = [squre root of](Radius of circle * gravity * coefficent of static friction)

So i looked up the coefficent of static friction of rubber ( tire) on dirt. which is about .7 and i chose a radius of 10 feet or 3 meters with gravity being 10 meters/second(squared)
(v-) = square root...best I can do on comp.
V= v- ((3m)(10m/s)(.7)
V= v- (21)
V=4.58m/s(squared) so 4.58m/s converted into mph is
.6214mph = X
.2778m/s = 4.58m/s.....so, X=10.25mph
So all you have to do is go a little over 10.25 mph and your back tire will start to slide out.

The advantage of sliding a dirt bike is that you can use the horsepower of the bike to drive it towards the center of the circle which actually allows you to travel at a higher rate of speed in some situations.

I want to learn every type of turning solution available so that I have options at different tracks. ;)

Interesting calculations. I seriously doubt I could go 10 mph around a circle only 20 feet across.

The law of physics has nothing to do with it. :coocoo: If you really read the thread, you will see that it is a method of overcoming the law of physics.

Just like the law of gravity. Where dirtbikes are concerned the law of gravity is only a suggestion. :cool:

Physics is involved, but you have to take it a step above high school or college physics. Engineering dynamics covers this type of caclulation. The tire may slide out at 10.25 mph, but if you add some other forces in to the equation, you can exceed 10.25 mph and still maintain the 10ft radius circle.

The calculation doesn't work to well for a few reasons. It doesn't take into account the mechanical interlock between tire and terrain, ie, the tread digging into the dirt. That would help you go faster. It also doesn't take into account the dirts friction and mechanical interlock on itself. Such as dirt with a loose layer on top that slides over the base material.

take it easy guys. he said it could( and already has) been nuked, but it is interesting. i do agree, however, that the calculation is not 100% correct. there is the type of dirt and the looseness, the type of tire possibly, and the ground elevation. it is a interesting calculation, though :nod: .

When discussing MX the more tools (skills) you have the better you will be. The set up of any turn within a race will depend in large part on your position entering the turn the the position of the riders in front/side/back of you. Knowing and being skilled at various turning techniques will afford you more opportunities to stay in front or keep someone behind.

Unlike Pred... I stayed at a Motel 8 so this is a for what its worth thing.

It's been called powersliding for a long time, and it's nothing new. If you have a flat turn without any ruts to dig in then you can keep your speed and, more importantly, rpm's up to stay in your powerband on a 2stroke...

I think 'Clint Eastwood' started the drifting thing. Before the "Rowdy" days, it was referred to as "power sliding." :)
