Q. It has fibre body is it long lasting - NTORQ?

Fiber body and steel body have both pros and cons in itself. Metal bodies are definitely heavier, which means poorer handling and acceleration compared to a fibre body. Fibreglass or composites are hard to repair though, and generally the whole body part is replaced if damaged, whereas metal can be pounded straight or filled. Fibreglass will withstand small bumps and just deform and bounce back. Hard impacts (major collision with a vehicle or object) will cause tears or cracks that are not easy to fix and hide. Metal will dent at even the slightest impact. Both have advantages and disadvantages. i would probably go for the fibre version just for the better handling. Longevity isn't really an issue. Both will last many years. If you ever have to transport the scooter in a truck, lighter is better, it's easier to load. In strong crosswinds the metal body is going to give you a little more stability because of the weight.

Well as said the height of the ntorq is less and even beginners can ride it smoothly after few rounds, my sis is 14 with 5.1 and she only struggled for first 5 rounds once you learn balancing it's peace of cake🍰.

Yes it is fibre body but it is of very good quality. Rest if you maintain it , it will last forever, but if not maintained it will not last even a year.
