I am getting my youngest son ready for a track day in June. I have taken him out a few times on some nice twisty mountain roads. He has been riding off and on for over a year, but now we have stepped up the pace. So in that aspect I am passing the torch but I am far from done! Looking forward to my 2nd season of racing! When my son and I go out, he rides my 400 and I ride the 250! He has tried the 600 but he felt it has too much power.
