does race line change ?

[jrshooter]

question does the race line change for different size bikes ?
at the track, i asked a track day coach some questions on a few corners, he said oh your on a 300 . i park and squirt this 1000. go ask this other coach for fast loopie lines.

Let's wait and see what @csmith12 has to say about your question.
He has experience racing with 250's and 600's.

yes in some corners. you want to carry a line where you can carry the most speed. corner speed is where its at.

why would not a bigger bike want to do the same thing?

its proven to be faster to get the more HP bike up on the fat part of the tire for WOT

He is pretty much right...

To keep things simple, it's all about the corner exit. You simply can't be very aggressive with the throttle while at the edge of the tire. A rider on a low power bike may choose to straighten out the corner as much as possible by taking a wider arch through the corner. This maximizes mid corner speed because rolling the throttle on exit isn't going to make up lost entry speed, nor will the rear "spin up" while on the edge. A rider of a high power bike may choose to "park and quirt" aka... "point and shoot", or as referred to at the track and in the dirt world as "square off" a corner to maximize time on the throttle. Yes, they give up a little speed mid corner, but the raw acceleration power mathematically makes up for the difference in speed + even more. Lap times and other telemetry proves it. And since they spend less time on the very edge of the tire, they can take full advantage of the higher power and put it on the tarmac vs managing that power throughout the entire arc of a corner.

Next is "steering with the rear." This is a very complex subject to wrap your head around but it's easily understood by going to the parking lot with your bike. Get moving and start riding in a nice circle. Now when you are ready... add increasing throttle and be careful to not add any steering inputs. Did the circle get bigger? Congratz!!!! You just steered with the rear. WTF does that mean? Think about corner exit. A high powered bike will go wider on corner exit simply due to the fact they are accelerating harder. So unless you want to further manage the power via a slower throttle roll on corner exit, then your line must be adjusted to allow for that aggressive throttle roll or you will find yourself off the track surface. Think about that when it comes to the line in linked corners.

Now... times are changing. A late model, race ready, liter bike will have a full gambit of rider aids on board to minimize the effects of the bike's personality on the pavement. These include traction control, abs, adaptive suspension, autoblip, quick shifter, custom fuel mappings, ect... ect.. ect.. all aid the rider to ride in a manner that is less point and shoot and enable the rider to push the bike to carry more corner speed.

Hope that helps

thanks i understand all of this, just did not put the pieces together.
