Customer Praise:

Astounded doesn't really describe how surprised and pleased I was today when a delivery truck arrived and there was my frame in the back. I thought it'd be nice, but is was better than that... Didn't expect so many brackets to already be in place... and the kick stand addon is a work of art in itself!

So all I can say is thank you very much and I will be back for one of your neat oil tanks and likely a gas tank too... there's going to be other parts I'll need too and I'll always check your catalogue of parts first.

My project has now got off to a flying start! Woohoo!
