The 2007 KTM 250 EXC-F has a fuel tank capacity of approximately 9 liters. The fuel consumption can vary based on riding conditions and style, but on average, it might achieve around 15 to 20 kilometers per liter. This means you could expect a range of approximately 135 to 180 kilometers on a full tank, depending on how you ride and the terrain. Always check your specific bike's performance for more accurate estimates.
This would depend on what type of oil you will be using for your premix. The oil base stock is either petroleum, semi-synthetic or synthetic oil and is mixed with gas at a ratio ranging from 16:1 (petroleum) to as high as 100:1 (synthetic).My 2 stroke I have is a 2001 Kawasaki KDX200 that I run Yamalube 2R at 36:1 with no problems.Although synthetics say you can mix them at 100:1 I would not, that seems way too lean to me.
