I've heard a lot or contradicting reviews and opinions Would it be ok as a new motorcyclist to get a Yamaha R6 or a ninja 6r as a first bike?

Yes, it would be okay to get a Yamaha R6 or a Ninja 6R as a first bike for a new motorcyclist. The reason an individual may get mixed reviews for these choices is due to the fact that new motorcyclist are advised to start with something like the 250cc motorcycle, for safety and technique reasons.
