· Soft tyre comparison. Following the Japanese GP, the FIM Grand Prix World Championship heads to the Pertamina Mandalika International Circuit in Lombok for the Grand Prix of Indonesia. The Indonesian circuit features an aggressively textured surface that provides good mechanical grip.
However, this is significantly affected by high temperatures, which can exceed 60°C and make the surface slippery, subjecting the tyres to severe thermal stress. These characteristics make Mandalika an ideal proving ground for developing new solutions. For Moto2™, Pirelli will therefore offer two soft-compound rear tyres: the standard SC0, successfully used by almost the entire field in 2025 as development specification E0125, and the new F0515. The latter uses the same compound as the SC0 but combines it with a newly developed structure designed to deliver greater stability and more consistent performance. To support its evaluation over the weekend, the maximum number of rear tyres available to each rider will be increased from eight to nine. · Front tyre options. For the front, riders will be able to choose between the standard soft SC1 and medium SC2. Over the past two years, every rider has opted for the soft tyre in the race because it delivers higher grip levels in high temperatures. · SC1 and SC2 for Moto3™. In the World Championship’s entry-level class, riders will be able to choose between the soft SC1 and medium SC2 for both the front and rear, two solutions that have both proved competitive over the course of the season. Last year’s results at Mandalika provide further confirmation: Honda rider Adrian Fernandez took pole position on the SC1 front and rear, while KTM rider José Antonio Rueda won both the race and the title on a pair of SC2 tyres.
