Hi guys ive just joined beacuase I'd like advice and help on building my own stunt bike, I've got a Honda nsr rolling chassis which I've been pinching stuff off for my other ones, I've had the thought that this would be near enough the perfect beginner stunt bike, it's already stripped and from all the other bikes I've seen it's ripe to be turned into a stunt bike.
From what I understand most stunt bikes have a cage on them which is essential really,
A hand brake for the rear or double rear calliper,
a cut out in the seat and the tank being domed inwards?
Also rise up handlebars seem to be common instead of the drop down bars.
I'm just wondering where to begin on this as I've never built a stunt bike before and this would be a first for me, also is there anything you would recommend that I could make or do to it? (Helpful recommendations!)
Thanks
Oliver
