Britain's Scott Redding has declared himself happy with his progress at the end of a three-day test at Jerez on the new Blusens Aprilia.
Redding, who won the British 125cc Grand Prix in 2008, has been moved on to the very latest factory bike and spent most of the Spanish test comfortably inside the top ten.
"There's a big change between this year's bike and last," said the teenager. "After three intense days we have got the engine doing what I want and I am happy with that.
"This puts us in good stead for the upcoming test at Valencia and we can focus on other parts of the bike setup. The Aprilia has great potential but we still have room from improvement."
