Former world champion Jorge Lorenzo wants the top speed of the sport's new bikes to be cut by MotoGP organisers to protect riders' safety.
The 1,000cc bikes generally prompted a warm reception following testing at Malaysia's Sepang circuit, where Marco Simoncelli died in October.
But Lorenzo, the 2010 world champion with Yamaha, admitted: "I am not happy with the top speed. We need to reduce it if we want to make it in the safe category."
World champion Casey Stoner easily beat Valentino Rossi's 2009 track record, set on an 800cc bike, by nearly a second on Thursday. But his time of 1min 59.607sec will not stand as a new mark because it was set out of competition.
