TOUGH RACE FOR ROBERTS JR IN TURKEY

Istanbul Park, Turkey - April 22, 2007: Kenny Roberts Junior's hopes of regaining ground after last-minute changes improved his machine were dashed from the start of today's Turkish GP, when an as-yet unexplained change in rear tyre performance meant he could do nothing but nurse the bike to the finish.

Roberts had qualified a disappointing 18th, after running out of time to find new chassis settings to adjust to a new and stiffer rear swing-arm... but in race-morning warm-up front suspension and geometry changes improved his situation. The rear tyre problem meant he was unable to exploit that.

The team is staying on at Istanbul Park to test tomorrow, to continue adjustments that will make the most of the latest rear suspension improvements.

The race, round 22 laps of the spectacular 5.340 km Istanbul Park circuit, was held in warm, sunny conditions, in front of a crowd of more than 40,000. It was won by Australian Casey Stoner (Ducati), his second victory in three races.

Kenny Roberts Jr.: 16th position

It felt like the rear tyre went flat. It didn't feel right on the sighting lap. I thought it might come in, but it never did. I thought it was flat and I was kind of nervous about what the problem might be; because when they're not the right pressure and have that type of feeling you can't be careful enough. Around the last five laps I also seemed to pick up a vibration, not sure if the two things are related or not but the guys will check it out.

Obviously there was a problem from the beginning of the race. Watching his lap times it's quite unusual to be so far off the pace at the beginning. It looks to be some issue with the back tyre. We checked the pressure on the grid as usual, and it was normal, but obviously it didn't feel right for him. Michelin are checking it out so we'll wait to see what they find out.

After the changes we made in morning warm-up he was fairly happy with the bike. I think we made some progress. Top speed seems to be a bit of an issue, but he was happy with everything else. We've got some things to try tomorrow and we will look to develop some settings around the revised swing-arms that we brought here.
