First eTesta R1E article is out now in eTesta R1E in Moto1Pro


We benchmarked two bikes last weekend, Aprilia RSV4RF and Ducati Panigale V4s and measured their performance using the new eTesta GPS7 Lite.

Come and visit us soon to find out how they did.

Aprilia RSV4RF

We will then compare the eTesta R1E against these best available Superbikes to see how we did.


We made it, eTesta Yamaha R1E is now part of MoTeC's Hall Of Fame. See details here:



This is how the bike has evolved over the months.

Our first test is done and all went as planned. The bike was piloted by Alvaro Guardia, Chief Test Pilot from the Moto1Pro magazine

Our plan was to drive installation laps to make sure all sensors are working correctly and all control systems are working as expected. Traction Control for example wasn't active during these laps. Throttle was limited to 80% for the first session, 90% for the second and 95% for the final. 

Some highlights from the data

  • Max lean angle was -57.6 degrees.
  • Average Heart rate measured by eTesta GPS7 was 2 bpm higher on the fastest lap compared to the second fastest.

You can read more details from the Track tests page.

Jerez is next so stay tuned.


Finally, It is Track time. All is set, sectors are programmed into MoTeC. Wish us luck and see you at Albacete!

eTesta is proud to announce our testing team:

Our Primary development rider is a fellow Finn, Pentti Tolonen. Pentti holds Finnish Superbike Championship and participated in World Superbike races in 1990. He is a ideal test pilot also because he has owned several Yamaha R1's, 2009 model included.

Pentti is joined together with Alvaro Guardia, Chief Test Driver of the Moto1Pro magazine and Jorge Torrecillos. 

El proyecto Etesta Yamaha R1E está en su fase final de desarrollo y ha llegado la hora de probarlo en la pista. Estamos orgullosos de anunciar quién compondrá nuestro equipo de prueba:

Nuestro piloto principal es un compañero Finlandés, Pentti Tolonen. Pentti ganó el campeonato finlandés de Superbike y participó en el Mundial de Superbike en 1990. Es un piloto de pruebas ideal por su experiencia y dedicación a las motos y también porque ha sido propietario de varias Yamaha R1, modelo 2009 incluido.

A Pentti se unirán Álvaro Guardia, jefe de pruebas de la revista Moto1Pro y el director de la publicación Jorge Torrecillas, quienes nos darán su punto de vista más próximo al de un usuario experimentado.


Been busy preparing the GPS7 for the track tests to make sure the driving line calculation works.

GPS7 can calculate and display how far the bike is from the ideal line, see the Line Accuracy, value. Value is the distance to ideal line in meters.



Quickshifter is now tuned:

It is done and the bike is finished. we'll take final photos and videos tomorrow. Next is the track so stay tuned, who is the brave one who dares to ride it. It will be published this friday.




Installed some of the GB Racing parts today, see the unique frame sliders for the 2009-2014 Yamaha R1. These were created together with GBRacing for this bike.



One of the things I checked today was how fast does the Inlet change it's lenght.

Here's the answer, 0.2sec, both directions:

Intake is opened at 11000rpm and considering the 0.184sec delay, rpm's are at 11624 at that point when accelerating.


Dyno day #1 for the FIRST MOTORCYCLE IN THE WORLD RUNNING THE ALPHA MOTEC MOTORCYCLE GPR PACKAGE is done and all is well. We did beat Yamaha in some areas but we are loosing in some. We are not releasing the results yet since product is not complete yet but here is some info. We are winning in torque and end speed but loosing on HP.

Here is the last run fueling data:

Lambda is looking ok and all parameters are fine.

Ignition data:

So, all looks good so far. There are things we need to change for the next Dyno session. Here's what happened yesterday.




Engine protection parts from GBRacing have arrived. Will be installed this week, stay tuned for pictures


Test plan for Dyno day tomorrow:

Pre checks:
- Check Lambda Bank1 and Bank2 readings.
- Cooling fan functionality, use Test mode.
- Check C125 Coolant temp alarm.
- Check rev limiter, set to 5000.

1. Warm up the engine and tune the fuel compensation parameters
2. Engine at 90C, tune Engine Charge Cooling Gain Primary/Secondary. Use 2000rpm / Lambda 1 so that can be used later for Fuel Film settings if needed.

3. Tune Fuel map idle area
4. Tune Closed loop fueling.
5. Turn off Closed loop fueling

6. Change Yamaha to ECU.
7. Check Yamaha ECU HP/Torque to get baseline.

30. WOT power run
31. Acceleration run

32. Change to MoTeC
33. WOT power run
34. Acceleration run

35. Did we beat Yamaha?

I won't bet, obviously the goal is to get as close as possible. All considered, it is always difficult to beat the manufacturer, manufacturer has (un)limited budget, spends a lot of time and has a lot of resources to perfect the parameters. On the other hand, manufacturer has to make compromises due to road and emissions regulations.

This is how the start looked like in M1 Tune:


Great news, got a permission from MoTeC to take the bike to dyno.  I will first measure the bike with OEM electronics and then change to MoTeC.

R1E logo has been earned now...


Like with every similar project, The Devil is in the Details. Tuning is on hold until the older R1 injectors have been measured and settings are available for the new MoTeC System 1.4. Bike starts and runs with 2015 R1 injector settings but only if the Efficiency Main (Fuel table) values are doubled. This obviously can't be right and this has to be corrected first.


When purchased, bike arrived with Metisse frame sliders which really look like an afterthought. 

To correct this, another BSB supplier has joined eTesta team: GP Racing. They supply engine protection parts for BSB series.

R1E engine will be protected with this kit and MoTeC C125 with this display protector.

We have also created Bullet frame sliders together with GB Racing, similar to these for the 2009-2014 bike.

Contact us if you are interested in these frame sliders.


eTesta Yamaha R1E came alive today at 16:35:40 CET. Tuning will start tomorrow.


Working today to make final checks in preparation to start the engine the first time. Checked the ignition to make sure everything is ok, don't want to brag but my engines have always started at the first try. Reason is simple: Everything like below is checked before even trying to start.

In the picture you will see the cranking procedure and the engine would have started if there would be fuel...

Engine Speed Reference State changes from First Edge->Search->Pattern Lock to Cycle Lock which means that the engine is now syncronised. At this point Ignition coils activate and there will be a spark. Engine would have started.


Previous owner had replaced the stock throttle with a Domino XM2 throttle set which comes with replaceable rings to adjust the throttle feel. 

Red (Progressive) ring is installed now which I don't want to use. I like to minimize the amount of variables and just use a simple, linear ring which is the green one.

I was interested though to see how the rings differ and what is the magic behind them.

Here is the result, I'm measuring the Throttle % at 5 different positions: 0, 20, 40, 60, 80 and 100.

Red = Is progressive and most likely the easiest one to ride.

White = Most agressive, linear in the beginning and is agressive at the end due to shorter travel.

Green = Almost linear, the one I want and has the most travel. 

Green one brings up an interesting problem: With green ring, this engine would have not made full power with the stock ECU. It maxes out at 94%, normally WOT is considered to be 100% and the ECU will never see full throttle...

Blue is after I adjusted the sensor for the ring and now it works as it should.

But, I'm sorry to say that these results are totally worthless in the end since this is a electronic throttle controlled by a servo, all depends how the translation table in the ECU is set. 

2010 Yamaha R1 has 2 modes, A and B. These modes are equivalent to the "rings" which Yamaha has built into ECU Throttle translation tables.


My quess is that Mode STD = Red ring, Mode A = White ring, Mode B = Green ring.

Actually, Red ring might have made the bike even more difficult to ride in Mode STD for example. Really slow throttle behavior in the beginning, then, above 20% engine would suddenly come alive. 

So, be careful when you purchase items like this, especially with modern throttle by wire engines. Domino XM2 propably works great with conventional throttles and simple throttle cables.

So, why do I want to use the green ring?

Simply because I have full control how the throttle will behave. I have total of 10 different tables how to change it and don't want to have another variable in the throttle which I can't control from the software.

Below is one of the tables, there is 10 of them. Different translation table can be used based on the position of the bike on the track.

Long story, don't hesitate to contact us if you have questions or don't agree...


Not happy with the fuel pressure sensor install and need to redo it. Solution will be installed here, come and see it in few days...


New GPS antenna was tested and results are better. HDOP is very good, 0.7 (vs 1.10), more satellites as well. We will start the tests with this antenna.


Front speed sensor is now installed and is a Hall type from Honeywell. No brackets are needed for this sensor and will detect the speed from brake disc screws.


Lambda sensors are now installed and exhaust is installed back. There is one sensor for each bank and will be controlled by a single LAM3 Dual lambda. We will measure the mixtures first with the stock ECU and then tune the MoTeC to have similar mixtures.

Wiring is made so that the LAM3 works also with the stock ECU, logging will be done by GPS6.


In preparation to get the GPS6 Dual working, I did some testing for the new antenna. Results were not good, antenna is not useable. It might work for some applications but it will not give good results. We will be using etesta LapAcc to record and evaluate the driving line where DGPS is mandatory to get 5cm accuracy at the track.

Below are the results, not good.



It is Saturday morning and thought to do something fun and work on a Audio analysis to see how quick the Yamaha MotoGP gearshift really is. Below is audio from Italy GP, Rossi entering the Mugello straight. Here's a quick summary what happened, you can see that he hits the rev limiter and the next gear changes. Gear changes are seamless, there is no way to beat this with a standard gearbox.

Here's a short video how this was done:



Finally, exhaust lambda sensors are welded in and exhaust is installed. Since the exhaust is Titanium, I had to find Titanium O2 bungs. Set was ordered from UK but the package was lost by Royal Mail. New ones were ordered from US and arrived early this week. 

If you need Titanium (Or steel) O2 bungs, we have these in stock in our store.



GPS Setup has been changed, will use these antennas instead. Very small and compact antenna. Gain of 26dB and easy to install below fairings with velcro.

Antennas are available in our store: Active GPS Antenna, Ultra thin


Time to bleed the brakes, brake fluid has arrived. Exhaust gaskets and reverse thread nut added to the store and parts lists.

Clutch switch was put back today for security to prevent starting while on gear.


Good time for a break while waiting for the O2 bungs to arrive from USA. We will have these hard to find Titanium O2 bungs in our stock shortly, size is M18x1.5.

We were invited to go and see the private BSB test this weekend here in Spain. More news to come depending what I can share.

Meanwhile, read our Introduction to Systems: Driver Controls.


Final assembly has been started.

Otherwise things are on hold while waiting for Titanium O2 sensor install parts to arrive from UK, they have been on transit for a week now. If somebody has these in Spain, please contact...


Gear position sensor install kit added to the store now. Also a new category Yamaha R1E Kit Parts was added to find all of the parts easier.


Last design element is done, it is the Limited edition label as shown below. It will be in the same location as the 50th Anniversary logo was.


We designed a holder for the GPS antennas, there will be 2 of them. One behind the seat and one at the front.


Introduction video to etesta RE1 features. Project gallery has been updated and has more high resolution pictures of the display and controls.


Gear position sensor has to be changed to a different type and some adapters are needed for it. A normal rotary potentiometer will replace the stock OEM sensor.

Some new pictures have been added to the Gallery, take a look.




Mockup is complete and no surprises so far. All sensors are tested and functional but need to look into the gear position sensor.

Livery design work has started, should be done early next week. Here is one element...


Fairings have been painted now, color is Toyota Super Brigth Yellow TOY576 (G1).

Mockup will start tomorrow, with all of the wiring and sensors in place. Stay tuned for more videos and pictures tomorrow.


First systems and sensor check. All looks correct, throttles and all other sensors are correct. One change were made to ignition switch, fuel pump priming happens when the key is turned on. I will change it so that priming happens when Engine Run switch is turned on.


Fairings are being painted. Exhaust will also get the bungs for O2 sensors. Titanium exhaust is very light.




Finnish, Polar Technology will go also into the Yamaha R1E project. Heartrate and RR-Rate will be measured with the belt and sent to MoTeC via CAN to be logged.

Product BIO1 is still under development but the prototype works. Should be ready when the bike testing starts.

Preparing also for paint, The Doctor will be gone for good.


First power up today with wiring, ECU and display:
