View Full Version : SAFELY Fast

This post is prompted by (but otherwise unrelated to) a recent BARF thread about a high-speed mountain road crash. There are some important lessons there for n00bs (and not-so-n00bs) but they are more general than that specific incident, road, or rider, and they need to be addressed outside of that context.

I think it's important to talk candidly about speed. Regardless of what we might say publicly, we all wick it up to illegal levels occasionally. But some riders can do it without sacrificing a significant degree of safety, and that's the hard part. Any monkey can twist the throttle on a sportbike to make it go fast, and many do. Many also come home to Mom & Dad in a box. When we grizzled veterans deny that we speed, we miss a teachable moment. Prospective lawbreakers are left to learn everything we've learned from scratch--and to repeat the mistakes we've made.

Skill vs. Risk

A common misunderstanding among n00bs about speed has to do with skill and risk. On the street, the fastest rider isn't necessarily the one with the best skills. Often he's the one willing to take the most chances. If two riders reasonably close in ability are on the same road, the one who reaches the top of the hill first will be the one who has put himself in greater danger. In fact, a better rider--one with a shelf full of trophies to prove it--may fall behind because he'd rather take his chances with a gravel trap tomorrow than a guardrail today.

If you're unaware that risk trumps skill on the street, your competitive nature might cause you to take chances that, under different circumstances, you'd never even consider. Following your buddy over a nice bit of twisty pavement, he starts to pull away. You're not about to let that happen, so you pick it up a bit to keep him in sight. Maybe you feel completely confident at the elevated speed, and if so, that's fine. You're digging deeper into your reservoir of skill to maintain his pace. But maybe you don't feel so comfortable, and you begin to make mistakes that could turn out badly. Now you're keeping up not with skill but by increasing risk. At that point, if you want to get home safely, back off and let him go--even if it cuts the ego a bit. Never get into a risk-taking contest on a motorcycle. A rider who would play Russian roulette with two loaded chambers will beat a rider whose limit is one--though he has a much shorter life expectancy.

Choosing your risks

The risks we face on the street come in different forms. There's the risk that the next turn will be strewn with gravel just beyond your line of sight. There's the risk that the oncoming minivan driver isn't looking far enough ahead to figure out that your motorcycle--at 120mph--is going to interfere with his left turn. There's the risk that you won't judge your speed for the upcoming turn well and enter it too hot. These three examples comprise two very different categories of risk. The first two are unknown to you. You've never seen the turn before, and the driver is just a random figure behind the wheel of a random vehicle. But the last is something you have experience with. You've practiced judging turn-in speeds and making accurate steering inputs, so you have some idea how likely you are to make a mistake (and we all make them). It's the kind of risk you can estimate with a bit of confidence. Prefer risks that depend on your own skill. Avoid risks that depend on random events.

We take risks for the promise of a reward in the form of fun, but the risk/reward relationship can vary widely. Riding fast in traffic or into a blind turn carries high risk, but the payoff in fun may be no greater than riding at the same speed in a safer spot. Imagine that you're approaching a two-turn combination you've taken many times before, a blind right-hander followed by an open left-hander. The blind turn carries higher risk: there could be gravel on your line today, or an oncoming cage that blew the previous turn could be on your side of the road. Yet the knee-dragging fun is the same as for the open turn. So comparatively, the blind turn is a rip-off--too costly in risk--while the open turn is a bargain--same fun for less risk. Demand the most reward you can get for the risks you take, and if the price is too steep, take your business elsewhere. You won't have to ride very far to find a better deal.


Riding safely fast on the street is a highly brain-intensive activity; the size of your peaches has nothing to do with it. It requires constant assessment of sightlines, surface, distractions, and other environmental elements. But even more importantly, it requires continuous evaluation of your own performance. We all have good days and bad, good turns and bad. As an excellent essay (Degrees of Control (http://www.sportrider.com/ride/146_0310_bench/)) in Sport Rider magazine noted a couple of years ago, the best feedback we get is from ourselves.

Really well put, Dan. I'd been wanting to post something in another thread vaguely along the same line, but this covered it better than I would have.

The thing that got me thinking about it, beyond recent circumstances, was a poster's comment about not riding "above xx%." We hear that phrase all the time and I always have problems with it, even though it's usually well intended.

First of all, what is this percentage a percentage of? Let's say I'm claiming to ride at 80%. Is that 80% of how fast I could ride? Is it 80% of the way to being freaked out? There doesn't seem to be consistent meaning.

Second, it isn't really measurable. How do you know the difference between 70% and 80%? You don't. It's a precise sounding way of describing something much more fuzzy.

Describing your pace as being 80% seems to be relative to the rider. As such, it doesn't fully take the environment into account. It may account for what the rider perceives about the road, but it doesn't account for random variables and the "dangerous corners" you describe. You can try to compensate by setting your "percentage" even lower, but again, it's hard to measure and you can eventually set the percentage so low the ride isn't that much fun.

Finally, to describe my pace as being a certain percentage of what I am capable of, is also to say, "I could be going much faster. I'm holding back. This is nothing. I'm really a much better rider than what you're seeing here." In a group setting, you can often see everyone's "80%" becoming faster and faster. I've thought more than once how remarkable is was that everybody's skill level improved so much in one day. In fact it normally hadn't and group riders just kept upping the ante on each other.

Your post describes instead an approach that takes the environment fully into account, not only the global conditions for the day, e.g., it's sunny and warm vs. cold and rainy, but certain turn configurations and the possibility of unseen hazards. The rider makes risk/reward decisions on a corner by corner basis, which, in my mind, is as it should be.

Of course we all do need to set an overall pace that does take our skill level into account. Rather than thinking in terms of riding at 80% (or whatever), I think in terms of riding a pace at which I'm 100% comfortable. I can relax on the bike, turn exactly where I mean to every time, not make errors on the throttle or brakes and can maintain a wide field of view. Conveniently, I can measure this, as I'm either succeeding at these things or I'm not. Then, within that envelope, I'll make corner by corner decisions based on sight lines and layout.

i think there needs to be more emphasis on this kind of mindset in the riding community. well put... thanks for the post!

Nice one Dan.
I'm often left behind by a couple of my friends. I can see them doing things that will get them killed, and I just have to let them go.
One of these days....

Have you looked at my "crash survey" in the crash analysis board?
I'm finally putting together some statistics that could demonstrate to Julian Solos that it is possible to manage the risks of riding.
The one thing I brought out of that entire sorry episode (sorry that Julian was such a stubborn SOB that any dialogue quickly devolved to people calling him names) was my almost obsessive fascination with the subject of motorycycle safety and risk management.

The rider makes risk/reward decisions on a corner by corner basis, which, in my mind, is as it should be.That was as lesson that took me a long time to figure out. I would go through a turn and realize that I wasn't using much of the motorcycle's capability--not taxing grip or lean angle. My first reaction was that it was a skill deficiency and there was something--I wasn't sure what--that I needed to improve. But eventually I figured out that I was slow in certain corners for good reason: the unknown.

When I finally understood that about myself--that I couldn't blindly throw the bike into a turn that might present a hazard I wouldn't be able to escape from--I was able to progress faster. Rather than worry about turns I couldn't attack, I focused on the ones I could. Applied to those turns, the lessons from the books and the track schools made sense.
