In the today print issue of AMS (Auto Motor Sport) is an track driving review of the MotoGP M4 on Losail Circuit in Qatar. They also claimed the S55 as not so sharply throttle responsive as the old S65, but because of the overall performance this doesn´t matter much, there is enough power out of the engine and with the Akrapovic Performance Exhaust it sounds like an/the V8.
Included is an small article about an comparison between M3 vs. M4 ... in this article they quoted for M3 and M4 identical performance and identical (reached) Nurburgring times of
round 7.50 min !!!
