Once again I come to you with a bit of tongue in cheek stuff again.
I'm going to hang my balls out and say that of all the Vintage Motocross bikes the humble 125cc is the hardest bike to restore.
The reason I say this is because very item on a 125 is so flogged out, bashed around and butchered up again that at times you wonder if it is even worth restoring.
Now of course all bikes need saving but the 125 has to be the hardest. Everyone has trashed the little buggars to within an inch of their lives and the maintence has usually never been done properly, if at all. Add to the fact that most people start off riding 125's, so at times they are miss treated and abused.(not like a big open classer).
And then you get the fast experienced rider on a 125 and he can punt that thing around all day giving it death.
Right up to the time a VMXer finally saves the 125 from a fate worse, than a fate worse than death, the bike may even have been used in some torturest farmers shed for all manner of horrendous jobs. The horrific things that get done to these bikes is unbelievable.
So I take my hat off to the restorers of 125's. You guys are the true specialists of restorers.
