OP, it would be helpful to know your body build (height and weight) and also general physical strength. There is a big difference in the range of body builds and a short 120 Lb person and a tall 240 Lb person are going to be comfortable and safe on completely different machines. Along with height and weight physical strength is abilities do enter into it some. Someone who is heavy and all muscle verses someone who is the same height and same weight but much more fat than muscle and only has 1/4 the strength of the all muscle person is not going to be able to handle as heavy a machine as the all muscle person. I am not trying to be discriminating against any body build, it is just that it is what it is, and the physical fit and ability are important parts of handling a motorcycle.
I have a niece who is short and very very skinny. She is also all muscle. All her life she was always underweight but athletic. She runs everywhere even short distances when she was a kid. She has a new 500 cc motorcycle that sits low and it is a lot of bike for her but she can handle it and at her light weight it has plenty of power to go as fast as she wants. Any motorcycle heavier than that probably would be too much bike for her to handle.
So OP, what are your physical characteristics?
