Today I finally fitted Petunia with a proper set of off-road shoes. She's now wearing a new pair of Continental TKC-80s, which I always found to be a great tire for the dirt, and amazingly good on asphalt as well.
I also fitted another RAM mount on the front of the crashbar, just next to the front wheel, for my VHoldr. I won't mount the camera there for gnarly dirt work as a tip over would trash the thing, but for less crash-prone stuff it should be allow for some cool perspective.
