Touchdown, Or The Lack Of.

[Trevini]

The answer kind of depends what year your bike is. The earlier models up to about 2006/7 had shorter hero blobs on the pegs. You can still get them to ground out though   The longer ones on the later bikes obviously ground out a little earlier. 

 

That said, you can get to the edge of the tyre without them grounding out, although I guess that may be somewhat tyre make dependent.
