MotoGP rookie Cal Crutchlow is aiming for a front row start in his home Silverstone round, after finishing sixth and fourth in Friday's pair of free practice sessions for the British Grand Prix.

The Monster Yamaha Tech 3 rider, who has qualified a MotoGP best of sixth on unfamiliar tracks this year, is relishing the opportunity to ride on a circuit where he has equal experience to his competitors.

Silverstone rejoined the MotoGP calendar, with a revised track layout, last season - when Crutchlow took two wins, from pole, in the WSBK event run on the same track layout.

Crutchlow began the British MotoGP weekend with sixth in dry morning practice, then rose to fourth on wet tyres in the afternoon session. The 25-year-old was just 0.251sec from third place in the morning and one-second away in the patchy afternoon session.

"I wasn't too happy with this morning even though I was in the top six," revealed Crutchlow. "I had some stability issues with the bike and without that I felt I could have been in the top four this morning as well. We had a few issues to solve and it would have been good to have a dry session this afternoon to work on improving the bike.

"At least we got an opportunity to do some laps in the wet, so we'll have some experience of the track in those conditions if we get rain on Sunday. I'd like it to be a dry race so I can show what I can do, but I feel we're competitive in the wet as well.

"The conditions this afternoon were unbelievable. It was soaking wet in parts but in other parts, how quickly it dried out was incredible. One corner would be wet and then the next dry, so it was a case of understanding when and where you could push to gain time.

"The Bridgestone rain tyres held up brilliantly on the drier parts but going from dry to wet conditions is not easy because there is so much heat being generated in the tyres, it is easy to make a mistake.

"The support from the British crowd has been fantastic so far and I've been making solid progress, so I want to aim for the front row tomorrow."

Team-mate Colin Edwards understandably returned to action on Friday, just a week after breaking his right collarbone in a practice crash for the Catalunya round.

This morning's session was a physically demanding exercise for the 37-year-old and he rode at a steady pace to gauge the strength in his right shoulder and build up his confidence.

Edwards welcomed the arrival of the rain more than anyone else, with wet conditions easing the physical demands of tackling the fast and technical Silverstone track. The Texan finished 16th in both sessions.

"Today was all about getting back on the bike and building up some confidence after last week's crash," said Edwards. "I wasn't going to do any thing too crazy but the shoulder definitely hurts a bit. I'm in a bit of pain in the braking zone for right-handers and unfortunately this a right-handed track.

"Honestly speaking though the shoulder feels better than I thought it would. In the dry and the wet I was just riding really timid, particularly this afternoon on the wet track. The conditions were just about the worst imaginable because one corner would be dry and the next wet.

"Some parts were drying really quick while others it was still soaking wet. I had nothing to prove but at least with that wet session we've got a feel for the track if it rains on Sunday.

"Right now, I certainly won't be upset if the race is wet on Sunday. I'll take a wet race right now because the stress on the shoulder is a lot less than in the dry, but we'll have to wait and see what happens with the weather."
