Trackaddix Twin Sprints

Trackaddix is hosting Twin Sprints this weekend at MAM. E.J. Bender, Eric Foutch and Bobby Mills of Greater Des Moines all plan on joining me this weekend. Unfortunately, our fearless leader, Randy Norian will be racing on the east coast this weekend and will not be able to provide his usual sage insight. Check out the CCS points board for more information on all of these guys. If you plan on racing Heavyweight Supersport, Heavyweight Superbike or Unlimited GP either Saturday or Sunday I will see you on the track. Watch out; my bike is sporting new shoes.

MAM Turn 12


Look at the map. Turn 12 is a lot less tight than it appears from eye level. You can take this turn at a very high rate of speed. Once you turn in, you scrub substantial speed running on the smaller perimeter of the outside of your tires. Listen to the pros take this turn. The revs go way up. There is not braking, and the fast guys are still picking up speed at the turn in point. Following Jim Milroy around yesterday I noticed he took a wider line before turning into 12. This drastically straightens the turns and allows you to bring an immense amount of speed into the turn with you. On a smaller bike, with a less forgiving power band, hitting turn 12 right can keep your bike in the power band through the next few turns and end up saving you well over a second by turn 15.

Play By the Rules

Are you an amateur looking to ride more safely and cut time around the track at the same time? All you have to do is play by the rules. There are rules for the road and rules for the track. Riding track rules on the street or street rules on the track can get you seriously injured. More importantly, it can really mess up your bike. Given that most bike racers started out on the street, they are accustomed to many rules:

Road Rules

Push the right handlebar to go left;
Use the rear brake to stop;
Don't grab a handful of front brake at speed;
Stay on the seat;
Watch what is going on right in front of you;
Shift up to go up a gear and down to go down a gear;
Brake through turns;
Chop the throttle when the rear tire starts to slide out of a turn;
Do not drag any body part through a turn;
Watch your speedometer.

Those are all fine rules for the street. If you start dragging a puck turning onto your local mainstreet and hit a patch of sand, interia has just taken over the driving duties for you. You just better hope Mr. Sanitation engineer has quick enough reflexes not to put you at one with your bike.

On the track things are different. You are traveling at higher speeds (hopefully) and should not have to worry about sand or automobiles on the track. The rules for the track include:

Track Rules

Push the left handlebar to go left (countersteering);
Do not use the rear (at least until you start sporting white plates);
Use your front brake and lean angle to scrub speed;
Get off the seat and hang off through the turn;
Watch at least two turns ahead;
Shift down to go up a gear and up to go down a gear (if you have not switched your gear pattern, do it today);
Brake before the turn and use your throttle and lean angle to modulate your speed through turns;
Maitain or even increase throttle when the rear tire starts to slide out of a turn;
Use your knee as a feeler to gauge your lean angle;
Watch your tachometer and keep it in the powerband.

The problem is that even though we tell ourselves to follow the track rules, we sometimes forget. Unfortunately, we forget more often when we are under stress; the time when we can usually least afford a mistake. You have to view track riding like a video game. There are rules that go against what we KNOW should work. We just have to immerse ourselves in the rules of the game and trust that the rules will guide us through. Every time you go back to a road rule on the track, you dramatically increase your lap time and risk the well being of your bike, your body and, most importantly me and my bike, the rider passing you on the outside of the turn (I should know better).

Practice Practice Practice. Slow down until the rules become second nature. If you are falling back on road rules, SLOW DOWN. Once you trust the track rules and implement them all the time, increase your speed until you feel a road rule creep back into your bag of tricks. SLOW DOWN, concentrate and try again. In no time your times will come down and you will be riding more safely.

Remember. Trust the rules. Trust yourself. And always, always Play By the Rules.

MAM Turn 1

Turn 1 is very tricky. Miss Turn 1 and you have no possibility of properly tracking your line on Turns 2 or 3. Turn 1 requires a very hot entry with a very quick flick. You would like to stay just left of the centerline as you head toward Turn 2. Your goal is to straighten Turn 2 as much as possible and carry your speed into the carousel of Turn 3. If you go too deep into Turn 1, you have to swoop left, back over the centerline, to get a good angle at Turn 2. This not only wastes time, but scrubs off all the speed you need to carry into the Turn 3. If you turn in too shallow, you run across the centerline between Turn 1 and Turn 2 and run into the same problem. With my 750 GSX-R, I try to hit the apex of Turn 1 at 72mph and keep it just left of the centerline. Slowing down on the straight a little early to make sure you hit Turn 1 perfectly will pay big dividends come race day.

Congratulations

Congratulations to E.J. Bender for his first podium finish this weekend at BlackHawk. E.J. took home third in the UltraLightweight amateur class. E.J. led the amateurs for five laps and was turning 127s. Our next race will be MAM in June. If you are going to be there, look us up and share any thoughts you may have. We are easy to spot with Randy's gorgeous RS250 Honda with the perfectly reproduced Repsol finery.

MAM Turn 3


We just returned from a terriffic day of racing at Mid America Motorplex and pick up some interesting information on a new line through turn 3, the decreasing radius. While I usually enter the turn hot and stay as hot as I can, I stay interior of the centerline. Right before the radius starts to decrease, I chop the throttle slightly, causing the front tire to nose in right towards the rumble strip. Once I reach the rumble strip I get on the gas and try to accelerate through to the carousel.

Yesterday my blazingly fast buddy Randy Norian, on his smoking hot RS-250 was tearing me up on this turn. Given Randy's prowess on the track, I rarely get the opportunity to watch him anywhere on the track for very long. I noticed, however that near the end of turn 3, Randy drifts out past the center line and turns in even later. Since most guys get it in their heads that the radius decreases, Randy's move is doubly counterintuitive. Randy's angle not only gives him a running start at the corner, but flattens it out to the point where he can pin his throttle all the way to the carousel. While a tight line shortens the distance you have to travel, Randy's line allows him to stay so much hotter through the turn and blast out so forcefully, that the distance advantage becomes a non-issue. You typically cannot go wrong taking a decreasing radius a little hotter, a little deeper and turning a little sharper.

One problem you may encounter is that other riders might find the line surprising. While this is not a problem on a track day, if you had a better rider behind you taking a fast tight line, the apex near the rumble strip might get a little close if the rider passing you was not anticipating your rocket-like acceleration past the apex. It would be an unusual circumstance however that much faster rider was not taking this line with you, instead of T-boning you at the apex.

Welcome to BikeLines

What is BikeLines? Bikelines is a blog covering various motorcycle roadracing tracks, turn by turn, straight by straight, line by line. Feel free to post comments. The value of this resource is not in my analysis of each track, but in the assessment of the collective community. What works for me, may not work for you. The only way to bring down those times and bring home those trophies is to try different things. The more opinions we have, the more proven tactics you have to try.

Our first track is Mid America Motorplex, and we will be looking at turn 1.
