Welcome, you are obviously a very brave man, to ride this bike in Vietnam . I recently had a 2 week trip on a Honda XR125 from Hanoi south to Hoi An . Loved every minute in your fantastic country, but 1000cc on those bumpy roads will be tricky. I must say that if you learned your riding there you will be up there with the best riders anywhere in the world. All the riders I saw had amazing skills, most girls there had more skill than many boys here in Australia, it is just all the power combined with your difficult road conditions that will make it hard for you.The suzuki throttle makes it quite hard to ride smoothly in traffic. Look up throttle tamer on the forum or internet. I fitted one and it really helped to smooth out city riding. The traction control will help a lot when riding through water buffalo poo out in the country . Best wishes for some fantastic riding
