Starting from a ꦓ2013 best of fifth on theඣ grid, Nicky Hayden couldn't hide his disappointment at crashing out early in Sunday's race.

Hayden lost the front of his Ducati, like many others, as he turned into th⛄e left hander at the end of the back straight, on lap 6 of 25.

The 2006 world champion had just retaken⛦ fifth from Stefan Bradl, after dropping back t♏o eighth on lap one.

"I got a pretty good jump on the start, but some guys overt💎ook me going to turn one," said Hayden. "I had to make a few passes and once I got into fifth I wanted to do a couple🥃 of clean laps and see what kind of pace I had.

"But ღas soon as I got off the brakes at the end of the b🎀ack 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 w🅷e couldn't have got our best dry result of the year.

"There's nothing we can do🔯 now but take it o🍷n the chin."

Asked to compare how his Desmosedici was working relative to Bradl's factory💟-spec Honda, Hayden replied.

"In a couple of places I had more grip than him. There were some places where heᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚ had a little better acceleration with the bike picked up, 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 rivals, Hayden will be back on track at Cataluny🅰a for Monday's post-race test, where he and team-mate Andrea Dovizioso will again ride the development 'lab' bike.

"We'll test the ['lab'] bike tomorrow and see how that goes. See if we ca♋n find some potential with it ꦆand 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 one of the toughest tracks fo♑r 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 that 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 worst 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 ever♈ybody the drop off of the rear tyre is big.

"Tomor🍨row we have to decide which bike we will continue the 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 a lot better at this track."
