Well either way hittin the ground at 50mph feels the same if your on a 600cc sport bike or a 500cc buel blast.
how ever if you go down and loose your nerve then it's time to sell the bike and stick with the cage. But if you can go down and get back up, shake it off and mend what ever was bleeding, scratched, rashed and or broken and get back on with out fear then you should be on a bike.
