ive been riding for 9 years now.. i started on a 125 then jumped too a 250 then sat my ass on a 600 rode that for awhile got power hungry took on a 1000, nice power but definitely not as good as a 600 for corners... i suggest a 250 for beginners even if u decide to take the course if u sit on a 400 or 600 to start which most ppl do cuz they dont like the rear tire.... try a 250 u will learn agility on the street. heres a video that might make u want a bike
