The Perfect Line, Sight-Line or the Ideal Corner?

As keen motorcyclists, should we always aspire to ride the perfect line in a corner, or is there actually something better?

When I was younger, being an enthusiastic competitor and frankly prepared to take huge risks, I would have always aimed for the "Perfect Line" into, and out of every corner. This was developed from "the racer's edge" a winning concept that involved active counter steering plus the choice to use the entire road when cornering (or the entire lane). So start out wide, push down hard on the inside hand and bar (to counter-steer), drop the bike into the corner on the inside of the apex, then gently reverse the counter steer to lead you out of the corner on the other side of the road. ("Reverse Counter Steering" is the subject of a future blog).

When done competently, this will result in a very quick and much safer cornering technique, allowing a far higher average speed around that bend (if that is what you are after or course). It needs lots and lots of practise, probably more than 10,000 pratice corners as a rough guide, to become really proficient. But it's worth the effort.

This "racer's line" uses all the road,  (or the lane you are in hopefully) and has the distinct advantages, that the bike will remain super-stable, the corner is almost guaranteeed and most importantly, if a slight change is required due to gravel or a rock on the road or an unexpected pot-hole, the smallest change of pressure on the bars will enable you to avoid the obstacle with ease. Finding a series of these (as we did in Tasmania) is heaven on a bike.

This of course depends on three key things;

  1. Your tyres are in good condition and inflated perfectly. (Experince says that more than 50% or riders have under-inflated tyres)
  2. That you know how to counter-steer intuitively. This is easy to witness, when I follow another rider, and gives me a crisp idea on their actual competency within three corners. 
  3. The surface of the road is clean, smooth and ideal across the whole lane. 
While the first two are controllable, the third is actually the key factor to enjoying a relacing leisure ride. 

Let me use an example; I was once riding with one friend to the coast, on very tall motorcycles. He was a first class rider, with exemplary skills and knew the road very well. After cresting the range, we headed slowly down the hair-pin bends and came to the less steep section where the corners open up a little, and he increased speed. I was watching as he changed from the Perfect Line, to one that was more open, and passed through the middle of the lane. In my head I was saying "Amateur! He is getting slack - just watch me cut this corner". Which I did. And was nearly thrown from my machine, by a row of corrugations in the bitumen seal. A firm counter steer saved me, otherwise I would have been heading for the Eucalypts.

So this brings up a third key element - the Sight Line. 
Rushing into a corner where you cannot see the exit, is more than a brave move. The view may be blocked by an embankment, trees and shrubs or even another vehicle. You do NOT know what is around that corner, especially if it is oil, diesel or sand on the road. Or something stationary. A good example of this type of road is the one from Thredbo to Geehi and onto Khancoban NSW, where there are loads of blind bends. 

When you DO have a clear sight-line, then you can plan the corner with confidence, and more importantly have a "Plan B", such as an escape route, if something happens. Like a big kangaroo jumping across in front of you, or a herd of cows on the road (both of which have occured to me in the last three months!). Naturally the sight-line lets us choose the best road surface to ride on, and therefore the the Ideal Corner for both enjoyment and safety. 

There are other factors too. If you happen to ride a cruiser, such as the Harley Davidson Softail (eg Heritage or Fat Boy Models) where the maximum lean angle is about 23 degrees, then you need to choose a curve that is NOT the racer's line - otherwise you will be dragging your running boards and pipes. The HD Touring models typically have a lean-angle of 31 degrees, more than enough to really get into it.

So overall, for safety, hassle-free fun on Australia's roads, the Ideal Corner does not run the racer's line. Try it, practise and tell me if I am right?

Why Ride Alone?



While my preference is to ride my motorcycle with a couple of good friends, I am equally happy to ride completely alone. I regularly do that without compunction or doubt. Yet friends have said that they can feel guilty about it, so here are the reasons why I ride alone, with pleasure;

  1. On any Sunday; If I am riding alone, I can choose to go NOW or later, or not at all. It's my choice. I don't need to confer with anyone to decide on the date and time of my travel.
  2. Thinking Time; Once I have eased onto the saddle and made it out of the city streets to the open road, I hit the cruise-control and let my thoughts try to solve my problems, if not the worlds' problems! In 150 km, I can sort out my plan for anything!
  3. Peace; Everyone needs some "me time", including my family. This is a time of total relaxation, without any external pressures. I know my wife desires a couple of hours once per fortnight too - so she can do nothing, watch box-sets or whatever, and I will not be there to interfere! So we arrange just that, together. 
  4. Go or Stop; there is no pressure to keep riding or not. If I choose to ride 20km to the local cafe, or across the State, then that is my choice, entirely. I can choose on the basis of how I feel on the day, and make my own decision. I can also stop any time I wish for a pee or a drink. Any time. 
  5. Alter the Route at a Whim; Around my city, I have over 100 different rides to chose from, covering a few kilometres or 1000. And its my choice. Alone, it is also my choice  should I choose to change direction, mid-ride. One evening I rode south towards Cooma, and the night was so fine, I texted my wife I would be late, and road home via Tumut - a distance of over 500km for the evening. It was just perfect for that particular evening.
  6. Entertainment; Additional to just riding and thinking, I also play Podcasts and music of my choice. One day it is Heavy Metal, the next Classics. Or if I really wish to get into the background of the COVID-19 discussion, I can do just that with a bunch of learned podcasts.
  7. Safety; The risk of an accident rises as the square of the number of riders in a group. Frankly, the range of competency of riders in any group is, and will remain, very wide. If I am riding with say 20 others, there will be about three really competent riders, maybe 8 others who are safe, six that are a little dodgy on the day and three beginners or genuinely un-safe riders. Reducing the numbers reduces the risk of an accident, it is just that simple.
  8. The Road Less Travelled; I have found that in clubs, (noting I am a member of three of them), most riders want to ride somewhere they have been before, just becuase they know what to expect. About 5% are happy to explore options. And some REALLY like to try something different! For example, it is a rare Harley rider who will ride on gravel, even for a kilometre or two, but some of the finest rides around my State, include less than 10km of gravel. Frankly I prefer to explore. 
  9. Speed and Distance; Like some very good friends, I aim to do some much longer rides when I get the chance. I'm a full member of the Iron Butt Association (IBA #517) and some friends think that I ride very fast to cover the vast distances. Nothing could be further from the truth - the secret to covering long distances, is to keep the wheels turning, rather than sitting in a pub for hours. When I ride alone, I can choose the speed and distance, which maybe stop each 100km, or ride out 450 before the next gas stop. That is my choice. 
  10. Stress-Down; Life and work is demaning enouigh, and now there are very carefully researched papers from HD and universities, that confirm that you will be 28% less stressed riding a bike. For the nine reasons above, that will likely be more so if you ride alone.
So don't feel guilty. Get out and ride when you like.

Olaf.
