Husaberg Chassis / VIN ?

Yes, you are correct, it is a 2002. This frame was made in Sweden and your other frame was made in Austria.

there should be differences between the 2002 and the 2004 frame.

2002
under the main tube there will be two female holes side-by-side upwards these are for the coil.
the swing arm bolt holes are just flat metal.
the headstock is 28 degrees.

2004
the coil bracket is two metal strips hanging down with a female bolt hole in either one.

the swing arm bolt hole has curved metal around it to strengthen the area. also, one side has a little flat plate welded that means a swing arm bolt with a 'D' shaped end must be fitted. this stops it turning.

headstock is 26.5 degrees.

The steering head angle is much steeper on the 2004 frame as mentioned by Taffy.

The 04 frame will turn better than the 02.

you couldn't even see the differences we mention? do you have a white stick and a labrador?

I did it. the 2002 engine in the 2004 frame. the coil hung on one bolt hole. I used all the 2002 electrics, no attempt at an upgrade. anyway, what is an upgrade when the 2002 electrics were working just fine.

husaberg just changed the headstock angle and didn't even check that the front wheel would or wouldn't miss the exhuast headers or not. oddly enough, they used to hit the LOWER headers of the 450 and couldn't reach the 501 or the 650 headers as they are higher.

so it will be fine handling and ride wise. it'll be OK. I think that they need at least 20mm offset TCs, indeed I ran 18mm offset which was a lot better. how many people here care enough to change? Nobody.

so the 570 that started with 18mm offset ended with the 22s.
the 2004 450 started with 22s and ended with 18s.

strange world.....
