The Movistar Yamaha rider struggled early on in the 2015 season, failing to register a podium finish in the opening three races, a period in which his team-mate, Valentino Rossi, won two races and finished third in the other.
However, Lorenzo has not looked back since winning the Spanish GP at Jerez in early May, winning a further three races in succession as he stepped up to a level that none of his competitors have been able to match.
Victory at Assen this weekend will see Lorenzo move past Rossi and into top spot in the standings, and the Spaniard says that he's feeling better than ever ahead of the race.
“For a while we didn't have this bike that we have now and especially during the race our bike is very constant,” he said.
“We are able to keep a constant pace during all the race, so that is why we are winning so much and dominating on Sundays.
“Let's see what happens from now on in the future but for the moment I'm in very good shape and physically I'm stronger than ever."
The 28-year-old knows that he will have his work cut out for him if he is to win his fifth consecutive race, with qualifying in particular set to be a tough battle as the Suzuki and Ducati riders are also more than capable of grabbing pole position.
“Very difficult. Our bike is not the best bike to make a single lap – it's not explosive like the Honda so we have to race a lot to make the perfect lap,” he said of qualifying.
“Apart from Jerez where I could make an incredible lap it is very difficult to stay on the front row.
“Sometimes we are on the second row even if I make a good lap because sometimes we have the disadvantage of the tyre and you have some riders in front [using the extra soft].
“Anyway, we are getting the front row or second row to start well for Sunday.”
