The two-time WSBK champion who had retired at the end of the 2012 season, returned to action at Misano last time and will once again ride the ride the Aprilia RSV4 at Sepang
Whilst Biaggi enjoyed the racing time he got during the test, three of the four days were severely hampered by bad weather, which was a source of frustration for the Italian.
"Unfortunately, they were some unlucky tests. For three out of the four days we had available, it rained. Of course, I had to take a spill and we also had a couple of technical problems that slowed down my work, but those are things that are just a part of racing. We hope to be luckier in the week," the 44-year-old Biaggi told crash.net.
"Sepang is still an exciting track, but the only black spot is that I found the asphalt to be rather more bumpier than I remembered it."
World Superbikes returned to Sepang for the 2014 season after a long absence Aprilia dominated through Marco Melandri and Sylvain Guintoli.
