Jorge Lorenzo used the new 2016 control ECU throughout the final day of the official MotoGP test at Valencia in Spain and noted a 'big improvement' as the MotoGP World Champion finished fifth fastest overall.
Lorenzo, riding the 2016 YZR-M1 with the fuel tank now located towards the rear of the bike and using new front forks, clocked a best time of 1m 31.282s as he finished 0.222s down on Marc Marquez on Wednesday.
The 28-year-old briefly held the top spot before Marquez took over on his Repsol Honda and completed 48 laps in all at the Ricardo Tormo circuit to an end in his final outing of 2015 before the winter break.
“The 2016 machine we tried in Aragon is the bike that's adapted to the Michelin tyres to get the best performance. The fuel tank is on the back, behind the seat, before it was in front of the rider,” said Lorenzo.
“Today we focused on the electronics, as our lap times are still half a second slower than the lap time we made with the old version. The other thing we worked on is the front tyres of Michelin, which we are still trying to improve.
“I felt for example that under braking the rear is very grippy in the centre of the tyre but when you start leaning with the front whilst still braking, the front gives you more instability and you can't push so much with the brakes,” Lorenzo added.
“I used the 2016 electronics all day. Yesterday neither the power nor the engine brake was giving the best performance, so they worked on that for the next morning and today I felt that it was much better and we improved quite a bit during the whole day.”
