I never rode a dirt bike ever and started riding at the age of 50.
You have a few inches on me.
At 6'1" you will not have to worry about being flat footed.
If 2up riding is in your future plans a C50 is more practable, an M50 for some has a seat issue. But 2up on a C50T has all the equipment you will need, although most here never seem to have enough Bling.
Up here we have what is called a SE, it comes with the same equipment as a T but in other colors without the whitewalls.
Either of these bikes are great and the choice is down to styles and riding needs.
There is not a section for new riders but throughout the threads is info.
Use the search funtion on the top bar, key in new riders.
Ask any questions, but whatch out you may not get the answer you are looking for.
I hope to see you around. Enjoy the course.
