Hello and welcome to the forum
I love the 250's.
Here is some advice from a great friend racer/coach rider
To go right push on the right bar, to go left push the on left bar. This called counter steering and you learned how to do it when you learned how to ride a bicycle. Use your front brake mainly and use the rear brake lightly. Look where want to go, not where you are going. Always look far ahead and when in traffic behind a car, ride to one side of then lane or the other so you look around the car and see whats going on up ahead. Take your advice from riders who have been riding a long time, the older/wiser the better.
You will crash eventually so get geared up. And remember this, there two kinds of motorcycle riders. Those who have crashed and those that are going to.
There are old riders and there are bold riders but there are no old and bold riders.
