KUALA LUMPUR: Zulfahmi Khairuddin stressed that his charge Hakim Danish Ramli has to improve in terms of tactical maturity and mental strength after enduring a difficult outing at the Grand Prix of Indonesia.

The Moto3 rookie was penalised twice over the weekend. He was slapped with a back of the grid penalty for slow riding during qualifying one (Q1) at the Mandalika Circuit.

Despite starting last, the AEON Credit-MT Helmets-MSI rider did well to work his way up to a top-10 position during the race but was then involved in a last-lap incident with GRYD Racing's Joel Kelso which saw the latter crashing out of the race.

Danish was faulted for the incident and was given a three-second penalty. Despite crossing the line 12th, he was demoted to 14th due to the penalty.
