I'll jump in here with my tuppence worth.
1981, 17 years of age I walked into wheeled machines in Glasgow and bought an xs250. I liked it for no other reason than I admired a bloke down the road from me who ran an xs1100. Anyway 17yrs old I set off outside this shop in the middle of an unfamiliar city, with no training whatsoever (my only bike experience was cutting about the fields on an xl125 and a ts100) and within a month I had had 3 near misses and 2 slow speed fall offs, all my fault. A few weeks later I hit a car and ended up in hospital and with 3 endorsements (remember them) on my licence. I learned pretty quick after that and have only had one accident since then, his fault this time. The 125, 12bhp law change came in the next summer and I had passed my test by then. Later on compulsory training came in and oh how I laughed.
Shoot forward a few years and my oldest boy wanted a bike. I made sure he got every bit of training available and in his 4 years on a bike...50cc, 125 and now 535 he is a safe assured rider who could probably teach me a thing or two (like switching off indicators )
So the greater hp did not save me and the lack of training nearly killed me, whereas his route to bikes led to a safe and steady progression that have almost stopped me and her indoors from worrying our selves to death every time he goes out on his bike.
As a biker, a parent and an all round good egg, I see no problems with a steady progression through power
