I've been playing around with a Kwak GPZ500 or EX500 for a year or so! It got bent went after being hit by a van driver on auto pilot. It's been heavily chopped and shaped at the rear and kinda street fightered at the front... I have tried to junk anything that seemed pointless and did everything on a shoe string (most expensive thing I did was replace the rear tire) I'd consider it a bit of a rat and it sure to be after it has seen a couple of british winters!! But I suppose the question has to be at what point does a bike become a rat? Or is it all a matter of personal oppinion?

Just taken some new pictures of my gpz500ratfighter - I've had Hours of fun building this and now its road legal its been giving me many more hours of riding pleasure. A list of some of the work done is as follows:

• Re-fabricated frame
• Re-fabricated head stock and Renthal type bars
• All panels fabricated out of sheet alloy
• Tail section fabricated from scrap steel tubing sheet steel and a single seat hump from a zx600.
• Not sure what the seat is from but when first fitted it was really uncomfortable so now It now pivots on a couple of clutch springs (much much better)
• Belly pan is original but patched and riveted with sheet alloy.
• Tank is original but I have used more sheet alloy to fill the gap where the original seat fitted as well as create a tank protector.
• The Headlights I think are from a gsxr but I had to fabricate a frame to hold them.
• The engine is standard except the air box has been replaced by individual filters and carbs dynojetted . It runs well but not as well as the original air box.
• The bottle on the side is for coolant expansion and not NOS. (NOS would be fun though!)
