While Maverick Viñales and Marc Márquez emerged from the Sepang tests as clear favorites, with Valentino Rossi, Dani Pedrosa, and Andrea Dovizioso close behind, Andrea Iannone established himself as a genuine dark horse. The Italian was fastest on Tuesday, and left the test as second quickest behind Viñales.
Iannone has inherited a bike that is already well developed, and Suzuki brought engine upgrades to Sepang, which got them even closer to the front.
It was telling that Iannone did not spend much time testing parts, but rather focusing on race setup and working on extracting maximum performance from a used tire.
Tires were a bit of a problem for Iannone on the last day of the test. He crashed three times, including once as he was attempting a long run, the front washing out at Turn 1. The issue proved to be a vibration in low speed corners.
“I have a small vibration in the slow corners,” Iannone said. “In the fast corner the bike is perfect. There is no vibration, no chattering. But in the slow corner, especially in turns four, nine, 14 and the last corner, we have a small vibration at maximum lean angle.” That vibration got worse as the tires became more worn.
