Jonathan Rea insists he is in high spirits despite a disastrous day for his World Superbike title challenge when he failed to finish either race.

Rea was on a high heading to Monza following the double victory at Assen that put him within range of championship leaders Leon Haslam and Max Biaggi.

However, he would not find so much luck in Italy, the Ten Kate rider losing the front-end of his Honda on the entry to the Parabolica during race one before getting involved in a pile-up through the opening bend in race two.

With the latter accident leaving him with a sprained ankle, Rea has now lost ground in the overall standings to be 71 points adrift of Haslam.

Nonetheless, Rea is remaining positive heading to Kyalami in less than a week's time, the Northern Irishman vowing to start making up the difference by winning in South Africa.

"It's been a bad weekend for our assault on the championship. I made a small mistake at the end of the back straight in the first race when I was trying to avoid Leon [Haslam] and Cal [Crutchlow]. Then race two ended before it had begun when I got skittled off going in the first corner.

"But I'm not down in the dumps about it. It's times like these that you can really tell the strength of a team and I know that this team is really very strong. They gave me a good bike this weekend but we couldn't really make the most of it.

"I'm actually really excited at the challenge ahead, because we were able to make up quite a lot of points in the middle and end of last season. We'll all pull together now and I fully intend to get back to winning ways at Kyalami next weekend."
