Lets see, you were riding it in the dirt, crashed and recovered it, and continued riding it in the dirt.....I think that actually qualifies it AS a dirt bike...albeit a heavy one.
I dont care how heavy a bike is, I crash them all in the dirt at some point. A crash does not disqualify it as a dirt bike. If that is the case, every YZ, KX, CR, RM, KTM, and thumper I have owned was also NOT a dirt bike...and I have the X-rays to prove it.
