Starting from a 2013 best of fifth on the grid, Nicky Hayden couldn't hide his disappointment at crashing out ea🦹rly in Sunday's rꦑace.

Hayden lost the front of his Du🍸cati, like many others, as he turned into the left ha♚nder at the end of the back straight, on lap 6 of 25.

The 2006 world champion had just retaken fifth from Ste⛦fan Bradl, after dropping back to eighth on lap one.

"I got a pretty good jump on the start, but some guys overtook me going to turn one," said Hayden. "I had to make a few passes and onc🐻e I got into fifth𒊎 I wanted to do a couple of clean laps and see what kind of pace I had.

"Bu𓆏t as soon as I got off the brakes at the end🦄 of the back straight the front folded before I could do anything.

"It's really frustrating because it was the best weekend of the year as far as pace goes and to end♎ up in the gravel trap hurts. I don't see why we couldn't have got our best dry result of the year.

"Th♊ere's nothing we can do now but take ꧒it on the chin."

Asked to compar🦋e how his Desmosedici was working relative to Bradl's factory-spec Honda, Hayden replied.

"In a couple of places Iﷺ had more grip than him. There were some places where he had a little better acceleration with the bike picked up𒉰, but I'd managed to get a run on him and pass him into turn one. Then the next two splits were my best of the race..."

Like most of his riv🌠als, Hayden will be back on track at Catalunya for Monday's post-race test, where he and team-mate Andrea Dovizioso wꦉill again ride the development 'lab' bike.

"We'll test the ['lab'] bike tomorro🍷w and see how that goes. See if we can find some potential with it and make it as good as our standard bike, then decide what we do for Assen."

Dovizioso finished seventh in Sunday's grand prix, over 30-seconds from race winner Jorge Lorenzo (Yamaha) at onཧe of the toughest tracks for the GP13.

The Italian liked the ❀'lab bike at the previous Mugello test - although it didn't produce much of a difference in lap time - and confirmed that Monday's track time is likely to decide if it will be raced by the factory team at Assen.

"We knew before coming here th🉐at this track wouldn't be the best for us. A lot of our problem is the 'pumping' [up and down movement of the rear of the bike] and here is the wors🎐t track for pumping.

"It is really difficult to be fast with this movement at the rear. When the temperature is higher🐭 the pumping becomes bigger. And for everybody the droౠp off of the rear tyre is big.

"Tomorrow we have to decide which bike we will continue th꧋e season with. We have to make a comparison. We know that [the 'lab bike] chassis is different but the result is not a big difference. It is not what we need, but we have to understand the way and keep working."

Prior to the weekend, Dovizioso had expressed an interest in racing the revised frame in Catalunya: "We didn't have time to get four bikes ready for this weekend. But I don't think that chassis will be aꦜ lot better at this track."
