Reigning WorldSBK World Champion Jonathan Rea will use this week's Portimao test to confirm his engine settings and gearbox ratios ahead of the season start.

The Kawasaki man, who will fly solo as team-mate Alex Lowes is still injured, will pretty much have the track to himself in Portugal as only Orelac Kawasaki are also in attendance.

“It is really good to test again and I am excited to ride the bike - especially during these strange and unknown times," said Rea.

"We have got some consistency going inside KRT since we tested in November, then again recently at Jerez. It is good to keep the rhythm going with the new Ninja ZX-10RR racebike before the start of season.

"We have already tested some new ideas with power characteristics from the engine although the weather conditions were not 100 per cent.

"So, the main thing we have to do at this test is confirm things on the engine side and then fix our gearbox ratios. We aim to keep building speed and keep building confidence.”
