Nice to see your bike @velimir
Yes, it is not a must, calories, for a motocycle rider. I will never forget August 2016, when i had these series of parties all over and i couldn't just bring myself to watch those ugly demons that lets you put anything into your mouth. I came up with these strange pot-belly in just three weeks and not only do i feel so changed and awkward, my bike hated me for it. It almost spoke discontent like balaam's animal in he bible.
Riding on my bike then after 3 weeks off, i could feel my tummy greasing the fuel tank. I broke into laughter!
Ever since then, i've always fight the battle too.
