I am going to buy a dirt bike for trail riding and in the dunes. I have been riding since I was 8 yrs. old raced motocross up into my late twenties I thought I was a good rider the biggest bike I owned was a CR 250, got married and sold my bike haven't ridden for about 15 yrs, I sure miss having a bike . I want to get back into it but for recreation only. My question is do I get a 250 or 450. I am 6 ft tall and weigh 225 lbs. I don't want a two stroke. four stroke this time what size do u recommend? And what make and model. I prefer Honda's wouldn't hesitate on Yamaha WR.
