Let them hit, they are hinged and other than some noise and sparks will do little damage just lift your inside foot a little when it happens. When you start rubbing metal off the pegs then start looking @ rearsets.
You need to start hanging off if your not already doing so. If you are positioned on the bike properly (weight forward and balls of you feet on the pegs) your boots will touch down 1st. Until that is happening your money is better spent elsewere.
Again, get the fork/shock sorted 1st. But what the hell do I know...i'm just some jackass on the internet so get the rearsets.
I should elaborate a little more about myself since I am not actually such a n00b at all.
I have been riding motorcycles for 10 years. Always with a CB750 and some Ducati. My first Duc was a 2001 996, and what I am riding now is the Ducati Monster 1100 (2010).
Yes, my riding experience is Canyon Riding (90%) and Commuting (10%), and no track time until now, but I think the general idea of "You do not want to low-side/high-side", and you want to learn as much as you can is the same feeling.
The position of the pegs is not holding me back from stuffing it harder into a corner. I didn't feel like I needed to "stuff it" harder into that corner yet. I was way more excited that I had mastered entering it with smooth power, taking the right line and accelerating earlier and through out the rest of it. If you have ever seen MotoGP in Assen, NL this is the big sweeping, widening corder at the West end of the track. When I am ready to stuff it harder, I do not want to be thinking about my pegs scraping the ground.
On that note, you must have missed it in my first post: my boot IS scraping the ground, and I do hang off my bike at the track, I feel more like a gorilla on a tree than a rider on an italian steed at this point.
I just ready Keith Code's book before going to the track this last time, and before it was like trying to build and IKEA cabinet with out instructions. Now I had the instructions.
Sometimes those jackasses on the internet aren't so stupid. My first trackway they had a free suspension guy who adjusted my bike after a few laps, and that already made a hell of a difference so I know you are right about having the suspension fully set up. My trackways in Holland are done for the year and I am going back to California in 4 days so that is at the top of my list for when I get back this winter.
But it doesn't hurt to buy rearsets in the meantime, does it? Especially since they are cheaper in the states than in Europe.
