I have to agree. The 15" is the least I would buy to visualize datalogging. In my opinion the bigger the better. I also have a 11" that I use sometimes but it is really not easy to manage and read the data. I also have a 16" which is way better. As for CPU you will not need a lot of power but also there the bigger the better.

For the data to be useful you need a refresh rate of more than 1Hz that most phones have for the GPS. One good solution that I did before I buy a dedicate telemetry was an after market GPS receiver of 10Hz. This allowed me accurate GPS data through my phone.

Since I discover the datalogging I have explained a lot about my driving. The only problem is that you need time to learn how to translate those lines,dots etc. Every day in the track is a huge amount of info that you need to read and understand. As mentioned above some are using the telemetry to find what is wrong there, there or there, but some study all the data. The second part is very time consuming but in this way you cannot miss important things that do not show immediately. For example the braking G forces. A rider has in one lap 0.8g and in the others 0.6g. He feels the bike is excellent in both situations. With the datalogging he can tell if he won or loose time in the track and he can understand WHY. This is sooo important to know. If you can correct point by point your driving guided with telemetry, you are going to be... a faster and safer driver. Here is an example of data at the track comparing 2 laps. You can see the Speed (most important channel), Throttle, TC, Brakes, Gear and the delta (comparing the laps and showing where you loose and win on the track via GPS). The good thing a bout BMW S1000RR is that you can see a lot of channels (>24) as in most modern DTC,Traction,Ride by Wire bikes. In earlier models you have less information. Also most softwares allow you to create channels that you need. For example you can measure trail braking or total forces (lateral longitudinal etc) A very good site to start with is http://www.datamc.org

Welcome Vasilis. Exei oraia pragmata na diavasis edo.

Yes, thanks for the tip. I figured the tail fairing has more shaking leverage than the triple-clamp, similar to what you say for the mounting bracket. Nice sound work, what camera and software did you use for the lap time/tracking layout? I thought all action-cams have hardware stabilization. Is it Sony better than Gopro at this? No I believe only Sony has the image stabilization for the moment. I used dashware for the track and time layout.

I have a GoPro and found out that the shorter the bracket, I get less vibration, which is logic. Even if I put it on the tank cover which is not solid and it does vibrate I have more than acceptable results even in very bumpy tracks. If you want even better results then you should go for image stabilized action camera like Sony and no more hard shacking.

Well basically if someone wants to choose a tire profile he also needs to think in what kind of bike he will use them besides his preference. A lightweight, nervous bike will be very difficult to make brake and turn in fast without scaring you. I have used Pirelli SuperBike, Michelin Slick with V profile and Dunlop KR Slick tires. All of them are the best competition tires of each brand. The most aggressive profile of all was the front Michelin V profile. When you first tried to turn it your first thought was I "feel down". It needs more power to turn because they are heavier but when you start turning, your brain needs to be recalibrated for that front tire. The Dunlop was in the middle with a bit more round profile than Michelin but still aggressive.The Pirelli has a more round profile of the three and its more predictive.Its lighter and needs less power to turn but it does not "fall" as the other tires. I personally like the Dunlop better and choose them to be my tires for the track.

Is the lean angle on your 1299 measured with the bikes gyro? If yes then its not accurate. It measures the bikes angle but it does not take into account the track camber. So the 50 degrees is not 50 degrees, its way less. Also if speed is not enough knee dragging is not necessary. I never try to touch my knee, it just happens when my speed is high enough for the particular corner. When it happens I am not trying to drag it, I just touch and go. I even pull my knee up if the bike angle and my speed gets higher until I feel its safe for the bike and me. Here is a pic of me in a corner. When I saw it I thought that my body could be just a little bit more out of the bike but the rest, I think are as they supposed to be.

Most riders believe what they can see or feel. You put more preload on the springs "it feels stiffer, doesn't it"?Please share more.

Really nice idea the Plasti-dip. I bought an aftermarket seat from http://www.race-seats.it/en/ It works really well and have it for almost 6000km with no problems.

My stock seat at S1000RR was very comfortable for a a supersport bike. I upgrade it with one of the Race Seats. They keep the stock base but they improve the inside and outside material. Its super grippe, as I prefer, and more comfortable than the superbike thin material they put for seat.

I have a BMW S1000RR with ABS/DTC system and also had a GSΧR600 K6 with a Bazzaz traction contril system. I can tell you that traction control if you know what you are doing is great. It allows you to go further and further in learning how to open the throttle. I admit that S1000RR's DTC can be less intusive but that can be corrected with the Calibration Kit. The Bazzaz system does not have any sensors for the rear wheel but you can adjust many parameters. Now the S1000RR ABS is very good on the road, very good. On the track the only problem is the rear wheel on the brakes. When on heavy braking the rear wheel lifts and it engages the ABS and by doing that it unstables the bike. I think that the ABS and traction control is the way to go, especially on the public roads. There is always the button for someone to deactivate them...

Hello. I am going to participate to a trackday in Misano the next days. Does anyone have any expirience on this technical track? Well its going to be a blast

You will not have any problem with the bikw or the tyres. Both will work just fine for the school.

Did sent you email a week ago almost. Email is my nick name Drioannis

I am interesting of purchasing a pair of the new Dunlop KR106/108 compound 5 rear and 3 front. Are those tires the "new model" of the numerical pairs (ex 8813/8838)? Are on those tires the correct pressures the same as the "old model"? Has anyone tried the new model? The new compound are more rounded in front but with harder construction.

I also have the AIM EVO 4 and an HD camera on my S1000RR and it works very good! I also have AIM LCU One for AFR info.S1000RR has many many sensors recognized by the AIM software.It really helps you to improve the technics that can be used in many situations. Here is a video that I made

I've seen it also at the MotoGP.They tape a part of the radiator in cold weather.

I have a BMW S1000RR 2010 and AIM telemetry with PCV and Autotune.Also in the telemetry I have an AIM LCU One with Bosch 4.9 lambda(the exhaust has 2 lambda holes).The 4.9 as you already know is a revised version of the 4.2 that the Autotune has.The newer version does not need calibration,it auto calibrates every time it starts and its more accurate than the 4.2(wish Autotune had the 4.9). Well on the dyno the 4.2 sensor shows richer than the 4.9 by maybe .4-.5 on the AFR which is a lot.I checked the 4.2 sensor (dynojet procedure with blinking light etc) and its OK.I think that 4.9 is correct and 4.2 is not because of the color at the exhaust,it got better when I made custom tuning by 4.9.The 4.2 has maybe 4000km which is not that much. With the AIM telemetry I can have AFR measurement 50Hz (50 times per sec) and I can see it in comparison with throttle,temp,RPM etc and I know what AFR I have very very accurately at every point in the track(with GPS help). 1)What can I do with the 4.2 sensor.Is there a way to calibrate?I know there is a procedure with a mix of gas at Dynojet centers but I have one 800km away separated by sea. 2)If for example I have a target AFR 13.0 on 20% and 40% at the same RPM and +5 on 20% and +15 on 40% on the fuel what will the 30% be.Is there a formula for the interpolation? Wish there was an option for better resolution for the throttle(you can transfer that to Dynojet ). By the way how are things with the BMW S1000RR ignition module?

Excellent answer !!!

I have a question about Powercommander and %throttle.I am trying to tune my bike on the dyno and I would like to know for ex 50% throttle in what %throttle should I make the changes?I have in the track many 50%,32%,28%(telemetry)throttle openings and I want to tune it on those areas.Should I for ex the 28% be tuned on 20% or 40% on the map? Thanks

Ok lets go deeper with a question. How is the AFR been affected by the weather conditions?Is the AFR getting richer or leaner in hot,cold conditions?Is there a rule?

My thoughts on the video are that it is rider error.The camera might produce this vibration effect and not the suspension - tires.I think that he fell down because he had completely closed throttle at that point of the track.I never been at that track so I do not know how it feels but from the beginning of the video I was looking where the throttle will be closed to long.

The HP4 will be very very good.They will soon release a new Race Calibration kit and combined with the GPS you will be able to change the settins(DDC,DTC,ABS,engine brake etc) depending your location in the track.

1.Yes 2.Tech spec.I ve used Stomp grip which are better(they have more traction than Techspec) 3.Better traction on my legs that help when I ride specially on track.
