Their logic is that you learn from the crashes you have and you will not make the same mistake twice and it teaches you respect and to be aware of your limitations and those of your bike.

I say the first time you take the MSF course should NOT be your last time taking it……..

Always stay alert and play the "What If" game when you are riding……

Not so much miles as risk management, and execution.

I’m not gonn bragg I probably have about 190 miles under my belt. personally I don’t think I’ll e fully confident until I fall atleast once, which I hope doesn’t happen on the street, maybe the track.

Often I see the ego driver. Where the real one has a quiet confidence and is more interested in talking about driving or riding in reference to other drivers or even you. They point out things without lecturing you or exposing some over-inflated views that are often majestic to the point that no one comes close to them….A real driver or rider who is advanced exudes an aurora around them that is only sensed by anyone who is aware enough to see it – no words are really necessary.

In other words when you think you know it all and can support that somehow with some crappy stats and you feel the need to qualify yourself? Then what you have is an "ego" at work.

Pay attention to everything, expect the unexpected, and scan and process constantly without ever becoming complacent. The more you practice good techniques the faster and quicker you will process information, it’s just simply a never ending job and you can’t afford a moment off….

There are a number of things that must happen before you could really be called experienced.

- First you must ride enough that the actions and feeling of riding a motorcycle become ‘natural’, that is, your brain develops neuro-muscular programming for the basic operations which must become instinctive. Like shifting, clutching, braking, controlling the bike in a skid, even to the way to fall or crash w/o adding unnecessary injury to yourself. Sounds odd, but I developed this on the scrambles track of yester-year. If you are going to fall a lot, like you will racing, you can’t afford to get hurt each time.

- you need to expand this envelope to riding double, riding off-road, riding with a lot of heavy gear, riding in heavy wind and/or rain. I have ridden in all of that including ice and snow. Maybe most riders never experience this, but then you did specify ‘experienced’.

Option for the exceptional student:
I used to have a Trial bike. Google it if you aren’t familiar with it. Trials ppl are weird, they can spend an entire afternoon in one little place, off-road, practicing how to jump a log, or hop the bike around on the back wheel. Much like skaters do with their stuff. I was never good at this. <sigh> But it is like a graduate course in motorcycle control.

- Practice doesn’t make perfect, it only makes permanent. You have to make sure you are practicing CORRECTLY. This implies some professional instruction (of which I have had none, didn’t exist when I started riding). However you get the knowledge, you should do it SOON because learning is easier and safer than un-learning/learning.

- Safety is a large part of all I have mentioned. But there is safety that is not related to how well you can operate your bike, and that is the set of defensive driving skills you WILL pick up or die. You have probably have had this drilled into you for years. Good. Now you need to take it to the next level where it changes your personality… to where you ‘expect’ that car to turn out in front of you, and you KNOW that the car behind you will cream you if you use our brake, and you are gratified, not surprised when the dazed driver next to you decides he likes your lane better. If ppl need to take an exit, they will find they need to swerve around in front of you, apply their brakes, then take the exit. <sigh> It helps to think of yourself as a fella with a broken leg on a crowded bus. Welcome to the road, son.
