So more info for you:
Your engine is a 2008. Your frame is a 2007. But that is not that uncommon as KTM does make a bigger batch of engines at the same time and they then end up in their frames. There is no matching the frame number (VIN#) and motor number. In your case I think your bike would have been completed around the change of the year (from 2007 to 2008).
I have not found a way to decipher what cc an engine is from it's engine number. And I have also not managed to find a way to decipher what cc an engine is from it's VIN#. I did put together the info re VIN and motor numbers that you find in the category: "Bike Tips And Tricks" in thread
Sticky How to read a KTM VIN# but that was now a couple of years ago. One day when I have the time I will update that post with later model details. But with heaps on my hands that I get paid for I can currently not justify spending a day or two working on KTM motor and VIN numbers sorry.
Said that, you should be able to find the motor cc's on the cylinder.
The engine is in the bike my vin number is VBKMXN4387M324927
Thanks. From the VIN# I can read that it is a MX bike. But that does not tell me if it is a 450 or 505 bike. As both had 4 gears that does not help either. So if there is no info stamped/engraved in to the cylinder re the cc's I am lost. But perhaps some others of our crew have an idea?
