Idk About it taking years.... I'm 21. This is my first Busa but I had a 2002 Yamaha R1 since I was 17 and I think by the, I will say 2 month I could ride a wheelie a solid mile.
maybe I'm a small percentage but its all in the confidence and knowledge of what your bike will do when.
First, kudos on your riding skills - Don't take this the wrong way but I started riding bikes a decade before you were born... I didn't say you couldn't learn to ride wheelies in weeks or months only that it takes years to ride with authority. At twenty one I had all the confidence in the world but its been tempered by the toll its taken on many of my cycle buds... With four years experience under your belt are you recommending that folks just start clutching up wheelies and it will all work out just fine for them?
They have machines that you can pratice wheelies on at shows and almost all the inexperienced riders loop it just like they would if they tried on their own!
I am glad you and your cycle are all in one piece and I sincerely hope it stays that way!!!
