The two days of testing at Sepang have come to a positive conclusion for Rossi and Vinales. The Yamaha pair, after completing initial tests at Valencia, travelled to Malaysia for the final test of the year, sharing the track with their Tech3 'cousins' Folger and Zarco.
Valentino was able to ride the M1 in its full 2017 version for the first time, after having only ridden a 'hybrid' version in Spain, now with the new engine and new frame. The Valencia tests left the Doctor with some doubts, particularly regarding the engine, while the chassis needed more work.
The riders didn't make official statements, but we can reveal that Rossi is pleased with the new bike. Over the two-day session, he had a lot of material to test and was able to complete the work programme, with positive results.
It was Vinales' first time on the 2017 version of the M1, as he concentrated on riding the 2016 bike at Valencia to build confidence (succeeding in doing so, considering he set the fastest time). Maverick too is pleased with the material he's tested at Sepang.
Not a lot of information has been released from Sepang, apart from the fact the riders faced a wet track on both mornings, with the sun quickly drying the track so that work could go ahead in the afternoons. Both Rossi and Vinales completed roughly sixty laps per day.
