I am interested to hear more...

Many many tips are on this video.

The ambient temperature in the video was 32C I think. The bike was on warmers but some time passed since they begin the session. The side of the tires get some heat while you turn and specially in the exit of the corner since it does not have contact with the tarmac in the straight line. The surface temperature is not the hole story but you can have some data and make some changes. Even in MOTOGP or tire development they use the same method. I include some photo of SBK and MotoGP and the last 2 are from my friend GSXR 1000K7 with 3 IR sensors.

The software is made from AIM and it integrates the data from the telemetry to the video that has been recorded with AIM camera. The sensors are made from Texsense and cost 200euro each. He will use 3 on each wheel (2 sides, 1 center). I have 2D IR sensor for the front discs. For the IR sensors he will use at least 8 (6 tires and 2 for rotors). He might exaggerate a bit but the truth is that if someone is serious about the racetrack then he will need the right tools to help him avoid unfortunate situations.

Me and a friend of mine are using IR sensors on the bike. We are also using them on the brakes and tires in the track (I only use them for brake discs). We also use telemetry to record the IR sensors and many other parameters like suspension travel, GPS, engine etc. The info from the IR sensors can be used to see how tire compound works in the specific track and conditions. Well he is a bit crazy with the sensors. In his new bike GSXR 1000 2017 he will install three IR sensors on each tire , oil pressures, suspension pots, IR temps for brake discs and calipers and sooo many others that I cannot even remember. Here is a video of him in Misano with some of the sensors showing

I have the Vesrah SRJL XX and they are excellent in the track. They last for loooong time and they feel very very good. They can be used on road too. I also have tried SBS dual carbon: They are very good until almost half their life. Then they feel like wood. Carbone Lorain C60 (or 59): Very good pad but it does not last for many kms (track/road) Stock BMW (Brembo): Good pads but in the track it will not last for long and it overheats easy Brembo pads that comes with M4 calipers: Good pad for road. Stock Brembo might feel a bit better

I also see the difference even in the same bike that now is 99% trackbike. Before my bike transformed in trackbike the tires lasted for thousand of km and not for 3 days in the track. Brake pads in the past lasted for years but now a year max. The fluids has been changed a bit sooner than its recommend in the manual but still not every 2-3 trackdays... Track is a very very expensive hobby to do.

This is how they look on the bike

Made the carbon tube protection for the potentiometers to protect them from the track environment (stones,dust,liquids)

Excellent writing about suspension reading http://www.datamc.org/2016/04/12/histograms-suspension-velocity-analysis/

All these are good points but for "feeling-reading" the traction there is only one word...EXPERIENCE. "Reading" the traction is the most difficult thing to to in the track. This is what makes the difference in racing.

If it really bottoms you will hear a loud sound when it does. The solution is adding more oil in the forks. You can start by measuring how much oil do you need to add 10mm of height, so you will not take apart of the fork every time you want to add or remove oil.Then try it with 10mm more oil and see how it goes.

Short shifting is a solution I used a lot when the bike wheeled after the exit of the corner. It helps a lot, as mentioned, when you know where wheelie will happen, move your body on the front of the bike as much as possible. Also if it is possible you can alter your wheel base (longer), gear ratio or tune your suspension by increasing compression damping or spring tension. Those last solutions are a bit radical but can be applied if it is really necessary. I would like to add for the 2010-2011 S1000RR users that after I installed the +1-4mm Alpha racing swingarm pivots, the bike just catapult straight forward and rarely wheelie if I do not want it.

In my opinion Dunlop KR 106/108 are a pro tires. They are more sensitive in tarmac type, temperature, suspension setup and rider technique. They are more demanding tires than Pirelli Superbike. BUT when you make things right this tire is AMAZING . If you setup it correct they also last way more than anything I have used even beyond the marker.

Since you have warmers, hit them hard from the beginning
