@gouki74 ever since the day I bought it, the sport bike stall in my stable had been filled.

[sffranky]

@louisbosco Thank you, Sir.

[jiminstitches]

@sffranky Looking good, its awesome that you've had that from new. Bet its worth more now than you paid for it?

@Denman-John will try to do a video of one full lap once I get my bike back and figure out the lap data from there. Will probably also pick the best

Full lap video of the final lap I was doing. Lap time and telemetry from the bike below..

@louisbosco What a f'n rockstar!! Two things: around 35 seconds you do a head shake like you weren't happy with something. What was it?

Around 2:25 you're coming out of a turn and it looks like you're starting a speed wobble. Was that just the camera or did you come out of the corner too hard?

[louisbosco]

@goosehd

refer to map below.

0:35 was a double hairpin, turns 1 and 2. it's hard to nail the apex entry and exit on the second. had a late apex in mind but felt I had gone in too early and just wasn't happy.

2:25 on the exit of 14, was the front lifting. if you look at the telemetry, that was the 1 degree of yaw. 14 is also a tricky corner that requires you to go deep and turn for a late apex out.

fwiw, all electronic reins were set at 2. low but not the lowest. including electronic brake, wheelie, traction control etc..

Heading up to Sepang International Circuit this weekend with Ducati Singapore. This will be my first track day on a F1, MotoGP and Grade 1 circuit. Boy am I'm excited!! Feels surreal!

So cool!

@louisbosco Thank you for posting that. Not sure what superlative to use to convey how much I enjoyed that.

[WhiskeySandwich]

@louisbosco fuck yeah! That hurts my internal gyroscope/gimbal. Looks super fun tho!

[goosehd]

@louisbosco So I’ve been thinking about the 2:25 minute mark (exit 14) quite a bit and wondering what you did/or should do to keep from losing control.

Do you:

1. Stay in it and ride it out
2. Slip the clutch and slightly roll off the throttle to bring the front end back down
3. Slightly drag the rear brake to bring the front end down
4. Let the electronics figure it out and enjoy the ride.

I would have been seriously sweating bullets at those speeds and am impressed you rode it out. I really don’t think I could have and have no clue what I would or should be doing in that situation.

[Jett129]

@goosehd Is feathering the front brake an option?

[goosehd]

@Jett129 I don’t know if it would because the front end was lifting. Feathering the front brake may shift the balance slightly bringing the bike back under control, but I really have no idea what you should do.

It looks like the bike has a steering dampener which would keep the bars from doing a tank slap which is what would truly scare the crap out of me. I’ve seen a few videos of violent tank slap episodes and I don’t know how anyone rides that out.

@louisbosco That was so much fun to watch you whip that bike and track into shape. Almost riding season here and this is helping.

[goosehd]

@Jett129 Been thinking about the feathering the brake thing quite a bit and wonder if it does help. The front wheel spinning should act as a gyroscope which could either help stabilize the bike or throw it into a fit. By feathering that front brake, it may help...once again, I have no idea and hope that someone chimes in.

Not that I can ride to that ability and would probably lose the bike in doing anything like it.

[louisbosco]

Tank slappers happen when you abruptly throttle during a corner, as most would call it a high side. It is also the one of a few fears in the back of my mind from my first track day. (The other being a low side with not enough throttle) From what i know, it greatly helps being smooth on the throttle as you exit the corner into the straight. Similar to a car, when you exit a corner, you'd want to ease into the throttle and let the return straight as naturally as possible and use all of the track.

What I've done is probably given it slight more throttle than needed, when aligning straight up, having the torque lift the front end by a bit. The clutch isn't used except engaging 1st as this bike is equipped with a quick shifter. From what I've seen/ experience, in most racing scenarios, the rear brake is little to almost never used at all, but I could be wrong. But then again, 208hp/123nm is more than enough to lift the front end regardless.

A few things to improve is:

-To go lower and using my knee as a guide. 50° seems fairly low but from pictures and videos, they're not as low as I thought.

• To be a little more confident on the throttle in slower corners as they greatly improve the momentum and help with CoG

@WhiskeySandwich soz about the 360 views, I might have gone a bit too far trying to show different perspectives. I'm not that great of a video editor

[Jett129]

@goosehd Front brake feathering is something that I found extremely helpful when going down twisty mountain roads,which is why I asked about it. Had a friend who was trail braking and hit a pothole which pushed his foot into the brake causing him to high side.

[goosehd]

@Jett129 Ouch!! The more I ride the less confident I am. I'm comfortable on a bike, but always amazed at how easy it is for a bike to get away from you. About 7-8 years ago, a freak downpour started while I was approaching a stop light. I started to brake and the bike just slid out from underneath me. I was only doing about 10 mph at the time and was amazed that I couldn't keep it up.

The thing is that I was gentle on the brakes and hadn't panicked. Still just chalk it up to luck, but I still haven't figured that one out.

[WhiskeySandwich]

@louisbosco no it looked great, not bashing your editing or the video at all! I just mean that it tricks my sympathetic equilibrium into a weird balancing quandary. lol

...they have meds for that but they may make you less aerodynamic and cause some odd looks.
