Home hero Stefan Bradl and Aprilia Gresini team-mate Alvaro Bautista will have a new swingarm and engine parts at this weekend's German MotoGP.

The Sachsenring is the slowest circuit on the calendar, meaning the RS-GP's power weakness will be less significant than usual while handling takes on greater importance.

"The Sachsenring is a decidedly peculiar track, where engine performance has little impact on the overall result," Aprilia racing manager Romano Albesiano confirmed. "Just imagine that maximum power is used for about 10-15% of the lap, whereas the electronics setup and the chassis features are fundamental.

"What is needed most of all is handling and the ability to find the right line on the turns, both in acceleration and without the throttle. Another delicate aspect concerns the first right-hander after a long section with the bike leaned to the left, a crucial point of the track that must be managed very carefully.

"As for our development path, in Germany we will be bringing a new swingarm, significantly lighter and with different stiffness parameters, and some components on the intake side of the engine that should guarantee a step forward in terms of torque at medium rpm".

Home star Bradl will be making his first and last home appearance in Aprilia Gresini colours following the recent announcement that Aleix Espargaro will partner rookie Sam Lowes in 2017.

Indeed, this weekend may even be Bradl's last appearance at a German Grand Prix - at least for the near future - if rumours of a switch to World Superbike are correct.

"It will be a special weekend for me," Bradl said. "Many of my fans and friends will be at the Sachsenring to support me. Despite the track not being my favourite, the excitement of racing at home is always very strong.

"Especially this year, since in 2015 I missed the race in Germany before beginning my adventure with Aprilia. I hope that my RS-GP adapts well to this track. A good result is within our potential and, all things considered, it would be particularly satisfying for me".

Team-mate Bautista was on the verge of claiming the RS-GP's best yet result of fifth last time at a wet Assen, but fell on the final lap.

"The break gave me a chance to release the tension from Assen. It was not easy, but now I am motivated and ready for battle," said the Spaniard, who is tipped to join Aspar Ducati for 2017.

"The Sachsenring is a slow, narrow track with a lot of left-handers, very difficult. As always, we are starting from zero, so we'll have to begin working well from Friday morning on the bike setup.

"We are doing a good job. It would be nice for me to start the summer break with a good race, battling in the top ten as we have in the last rounds".
