Q. Can we reduce seat height of RC 200 till 790 mm without problems?

You can i guess but not too much.because company owns bike for race or for sport so they give accurate height for sitting possition ,but in other sense ....for short height people who cant even reach the ground properly also ,but they are ktm lovers for them company also gives little opportunity.we can reduce little bit.

I guess doing basic design modifications on a bike like KTM which is famous for stability on high speeds is not a wise decision. Instead you can opt for high handlebars for ease of reach if you are short heighted.

Yes, you can adjust its seat height. Moreover, we would suggest you to get in touch with the authorised service centre as they will be the best people to assist you in this concern.
