I own a 2017-2018 demak 150 which i purchase brand new. So far i do not have any issues with this bike and it is competitive with any Japanese bike. I was using many Japanese dirt bike in the past as Honda XL 125S, XL 250S, XL 250R, Then Yamaha XT 200 , Suzuki Djebel 200 and it was the final trail i had before this. I do lot of adventure travelling in this bike and it is my personal long journey adventure bike too. In the mean time i did some modifications with the ttires and i do not like basically i hate supermotors and i replace the both tires the front 110-90-17 and rear 140-70-17 off road tires (dual purpose tires) and it was a real problem of finding off road tires to 17
