Leon Haslam says he is targeting his first BMW victory at Silverstone after qualifying on the front row of the grid, while title challenger Marco Melandri will get underway from sixth.

The British rider comes to this event determined to reinvigorate his 2012 campaign following a few disappointing races and is keen to show well on home soil, particularly after the infamous incident that cost him victory at Donington Park earlier this year.

Contending with the slippery conditions well, Haslam will start from fourth position on the grid as one of two British riders to have qualified on the front row.

"I am really happy. It is always nice to start from the front row, especially at the home race. We just had two or three laps of wet weather testing on Friday and then I didn't have a good feeling but the guys worked really hard and every lap we did and every time we changed the bike we made an improvement. The conditions were difficult.

"Some were pushing maybe a little bit too much too early so there were a lot of crashes. We built up and went faster with every lap. When I crossed the chequered flag I was P1, which was nice for a short while! To have a front row start tomorrow is important and I am looking forward to the races.

"The target is always to win. We still have some more work to do before the races but I am feeling very comfortable. I think the biggest decisions will be on the weather."

Melandri, winner of the last three races, played it safe after reaching SP2 in the knowledge that key title rival Biaggi would be starting from only 11th place on the grid.

"This was another very tough day. The conditions were really difficult with rain showers and changing grip levels on different parts of the track. In the dry we could not have hoped for a start position like this as we were struggling again with chattering.

"In the wet conditions the Superpole was not too bad but it was not easy. Just before I went out on my last run it started raining very heavily in the second sector. I was really scared of aquaplaning so I chose to take it easy.

"Tomorrow will be difficult, as you never know what the weather will be like here. If it is dry tomorrow morning, we will make a small change to the set-up to be ready for all conditions."
