fixed it for you!

Looking at the acceleration coming out of diamonds edge shows you're REALLY good there...both of you start at the same time and the initial slope is identical. My interpretation is that the weight difference between the 2 of you is what accounts for the steeper slope (slightly faster accel) on his tracing.

Freakin' sweet! Thanks for taking the time to put that up!

It's difficult to do during track days, but in open laps I can run within about 0.5 to 1 second of my theoretical fast lap. I'd bet racers can run within a couple of tenths.

Something else that is different, Larry is shifting at redline - 1.4K rpm higher than I am. That might put him in a fatter part of the torque curve after the shift. I'll be trying that next time out.

The G2X system is nice. We run one on the LSTD bike. Its great to compare data from the different riders.

Gabe, are you capturing throttle position or brake pressure?

That's awesome. Looking at the 2nd g chart, he gets his maximum braking done before you and back on the gas before you. Think it is the transition time from gas to brake and that is making him quicker? It looks steeper.

I think the initial braking on my line, the blue one, is me letting off the throttle, i.e. engine braking. Then I get on the throttle a touch and then brake again.

Larry hits the brakes at the correct time and then transitions back to throttle. He picks up 3 tenths on me in that section alone.

Now that's cool to see.

Laps 1 & 2 of Larry's looked like he must have still been getting used to the bike. Everything was kind of wide. He looked liked his line through Spice was wider than most others I have been watching.

Cool to see him still pulling lateral g's exiting diamond's edge onto the front straight with his wheel in the air. Think the front gets air borne more often because he is shifting later?

I don't capture gear position with the G2x right now. While it will displays gear position, it doesn't capture it. However, when I watched the two videos I realized that Larry is typically one gear lower than I am in most corners.

For example, in turns 1 & 2, I am going through there in third gear while Larry is in second. Coming off of the launch, through the keyhole, into the bus stop, and onto the back straight I am in second gear and Larry is in first. Larry is also in first coming out of diamonds edge where I'm in second. And finally, through the carousel Larry runs first and I run second.

I run a higher gear because, frankly, it's a little safer and easier for me to ride. I can use the throttle more aggressively and pin it much easier in second gear. I'll try it in a few places next time out and see how it feels.

Larry was fast on my my bike out of the gate. The video only shows his first three laps.

He ran:

1:46.063
1:45.717
1:47.136
and then a couple in the 1:50's due to traffic.

-Curt

Probably one of the coolest threads I've seen around here for a while.

Great post Curt!

Wish I had the $$$ to get this sort of information for myself.

Was Larry on your bike when his data was collected? Or did you put the hardware on his Kawi?

Nevermind. I just saw he was on your bike.

I was wondering if there was some sort of control to the comparison. I should have known better when it came to you Curt. Haha....

Great info! I was at MSRH this past Sat,. for the first time, and was struggling like at first...got it together by poaching some lines (time honored technique!) from a couple of faster guys, and finally picked it up, running fairly well in the advanced group. Larry's video showed some lines that I wasn't taking, and prolly should be, especially through the keyhole section, where I'm still not going well. That was really helpful, as I like the track, but am leaving seconds scattered all over the place!

I'm gonna review that vid before I go next time...and hopefully I can get some good lap times. All I need now is to get my XT lap timer fixed!!
