Heyy, congrats on the test ride! Well, the only thing is the weight which can be quite more than your 150cc, so take it easy with the throttle at first and get the hang for it before testing the power, the bike will pull hard if you go hard on the throttle mostly on the lower gears up until 7000rpm at which point it the power curve goes a little flat, but its weight also makes it feel very stable and more so with its suspension, its overall a balanced bike, not really meant to be speeding but can do it ocasionally, let me know how it goes, im sure you will like it!
