I am fortunate having a bike with plenty of ground clearance and knowing i can hang off okay and my knee wont hit unless i am getting rather extreme.
I went with balls of feet on the pegs on the 250 and it works great for a week then your pegs start scraping, just take out the hero blobs when that starts happening and you will be due for a new bike soon after that.
Meaning the learner bike has got you past the learning to ride the bike stage.
