Monster Yamaha's Colin Edwards has said he found some much-needed rear grip at the Estoril MotoGP test which he intends to put to good use at Le Mans this weekend but says he still needs to understand more how the chassis works.

The Texas Tornado is confident of a good result, however, as he loves the way his YZR-M1 handles, especially at the French track, but says that a top six may not be possible.

"I am really looking forward to Le Mans because it is a track where I've had a lot of success at in the past. The Yamaha YZR-M1 has always worked well there too with the sweet handling characteristics of our bike suiting the layout of the track," said Edwards.

"We had a really good test after the race in Portugal and found a good direction to work with for improving rear grip and that should help us a lot. The new Yamaha chassis has a lot of potential but we still have to understand it a lot more to get the best performance out of it.

"A top six in Portugal is going to be hard to repeat because the field is so strong this season, but that's what I'll be aiming for. This weekend is huge for Tech 3 and Monster and I'll be giving it 100 per cent to deliver a good result for both."
