Haslam, who recently joined Aprilia, finished second and first in the two races at Phillip Island, Australia.
Despite never having raced on the brand new Chang International Circuit in Buriram, Haslam is confident that he will be able to keep hold of his lead on the standings.
"In Australia my feeling on the RSV4 was excellent and I hope it will be the same in Thailand as well," said Haslam. "We'll be working from Friday to find a setup suitable for this track and I hope to continue the positive trend we started at Phillip Island."
Haslam also revealed that he has prepared himself for the hot and humid conditions and cannot wait to tackle the new track, which was designed by Germany's Hemann Tilke.
"I'm curious to see this new track that I'm told it features two long straights and some slow turns," he said. "I'm expecting very high temperatures and a humid climate similar to Sepang, so I've been training and I'm ready to take on even difficult climates."
