All right… it’s Track Day!!
Sentul is Indonesia’s premier circuit. It was used for MotoGP, WSBK, and several other international motor racing. It was designed for an F1 circuit, yet due to the economic crisis its chances to have F1 car racing on its tarmac is as slim as I will ever ride a Desmosedici RR.
Enough about its history, bellow is my take on riding at Sentul. I ride Multistrada 620, ST2 and a Monster 620 on it, all Ducati’s bike. The circuit is clock wise and 3.96 km in length.
The longest straight, about 900m. Top gear with speed about 180 – 190 kph on ST2, bit lower with MTS 620. Good exit from R12 is crucial to have a good top speed. But carefull not over do it as my experience latter bellow at R12.
Braking point for me is about 150m if I rode MTS620, bit longer with the ST2. From crouching position, you brake hard, down shift to 4th and let the bike lean to the right.
My first time experience braking hard from 180 kph on home straight was quite amazing. When you pull your torso from the crouching position, the wind resistance was immense! You just grip the handle bar as hard as you can while your thigh pressing the tank due to instense braking. Awesome!
Turn 1 is 90 deg right hand corner. Very importance you hit the apex properly. It is an intimidating corner, especially when you just flat out on the home straight. Too slow you loose momentum going to the high speed left corner Turn 2. Too fast you shall ended up on gravel.
My first try I only managed to get 80 – 85 kph at this corner. And it is slow. I tell you, the local expert here with Motor Bebek can maintaine 100 kph+ on this corner. With out braking!
Also, this corner need confidance for you to point the bike to the apex and to its exit. After several try I did improve. And on my last track day with ST2 I can get about 100 kph on this corner.
Turn 2 is relatively easy left hander. It is high speed, with minimum lean angle. You need good line exiting Turn 1 to keep the momentum going.
