The Rizla Suzuki rider appeared on top of the timesheets in both one hour sessions on his way to recording the fifth fastest time, just 0.403secs behind championship leader
Dani Pedrosa.
"Le Mans is a special track for me after my first grand prix win here last year," said Chris. "I have great memories and I'm really looking forward to this weekend. I think we have got the base settings about right, we progressed a lot in China - despite our misfortune in the race [when his chain came off] - and we learnt quite a bit about the GSV-R.
"The bike has worked really well here from the beginning and although we made a few modifications we are really pleased with where we are at the moment. We tried a number of tyres from our allocation and things seem to be quite positive on that side as well. I still think we have some room for improvement tomorrow.
"We'll try a few more things and hopefully move up the order!" he smiled.
"The team has good memories of Le Mans after Chris's incredible win here last year in the wet, but today we were grateful that the weather held off and we could continue to improve the GSV-R in the dry conditions," added team manager Paul Denning. "Chris had a disappointing Shanghai, but it clearly hasn't affected him at all, and this has been his most competitive Friday this year. He has been consistently fast and has built up his level step-by-step and he'll be looking to move even closer to the podium pace tomorrow."
But team-mate
Loris Capirossi couldn't replicate Vermeulen's form, struggling with set-up on his way to eleventh place - albeit only one-second from Pedrosa.
