Can someone explain to me the difference between a lowside and a highside. Post vids, as well as explain how to avoid. Thanks in advance.

Lowside (aka laying it down, washing out the front end, etc.)- typically caused by the front tire losing traction. The rider typically falls over with the motorcycle. Situations where this might happen is too much front brake going into a corner or hitting a patch of slippery/dirty pavement (fluids or dirt/gravel).

Highside (aka getting chucked off, thrown off)- typically caused by loss of and then sudden *resumption* of rear tire traction. The rider is literally thrown off the motorcycle. At higher rates of speed, the vertical hang time can be quite impressive. :| Situations where this might happen is during a rear tire skid and subsequent "fishtailing" due to overbraking, esp. in a curve. rider lets off the rear brake. Tire suddenly grips and the bike whips out of the fishtail violently. The other situation is the rider is applying too much throttle with the bike still at lean, the rear tire spins up and slides. Rider reactively cuts or chops the throttle abruptly to stop the bike from stepping out of line, tire stops spinning, regrips and again whips back in-line violently.

Of the two, the highside is the more potentially damaging to rider and bike. However, needless to say, both are to be avoided if at all possible.

As for videos and pics... I have a few links at home I'll have to grab. Don't have access to my bookmarks at work.

If you are impatient, log onto www.motogp.com and you'll probably find some free samples of both in their video archives.

Cheers.

Low side-general

Same as 'Tucking the front'- you lose the front end of the

bike. This can occur during a 'panic situation', you grab a

hand full of front brake while leaned into a corner  | en-

counter sand or some other debris during cornering | roll-

ing off the edge of the tires due to excessive lean angle.

Holding the brakes deep into a corner.

High side-general

The rear tire brakes loose and spins then re-gains traction

in an immediate manner; you the rider, are launched from

the bike. This can occur while encountering a oil, wet

or sandy patch on the road; both in the corner or str-

aight.

How to avoid.

Look where you are going and where you want to go. Watch

your speed; slow down in un-familiar areas. Learn the

skills; take a course or two. Where proper riding gear-

accidents do happen, be prepared.

The way to avoid a low-side is not to brake too far into a turn or lean too far over.  Both can break tire traction and, boom... down you go.  You should have all your braking done before you countersteer to make the turn, anyway.  Or you can hit dirt, gravel or oil while in a curve -- not much you can do about those but avoid them.  Once a low-side starts, it's over... bam, you're off the bike.

The way to avoid a high-side is to not cut the throttle or brake when you feel the rear end break loose.  Keep steady on the throttle, maybe stand the bike up a little, and it might recover without throwing you off.  You can hope so...

I came out of a left hander a little too fast. The next curve was a 200 degree sweeping right hand. About mid way through I noticed my speed was too high and I was going to touch the yellow line. I tightened my lean angled. But my mistake was that I adjusted the throttle, just a little to correct my line. As soon as I did, my front 208ZR went out.  I was on my slider hard for a sec trying to recover. which I did not. I got lucky a car was not coming in the opposite lane. And, it had rained the night before so I just went into a grassy spot on the side of the road. Very litte damage. Pulled muscle in my groin somehow.

Great explanation TEvo.  I had my first lowside about 6weeks ago.  It sucked.  Thank god it was at only about 30mph and I had on my leather jacket.  Minor damage and a little road rash from the asphalt eating my jeans.  Hit a slick spot coming around a corner.  Max600 I think has the best sum of the two diferent crashes.  lol

So in the everday situation cruising around town which is more likely to happen? For instance hitting a pothole or sliding on gravel?

Gravel = lowside
Pothole = highside?

Am i right in that assumption? Or are neither going to happen depending on the speed variable?
