Hi nsman sept of 02 I where in Sweden visiting the factory in Rorfors talking to an engineer I asked how come Husaberg dont have a 450
for 03 his reply was we do have a 450 tested and ready for production but higher authority wanted to deplete the stock of 400 parts that pre production engines had different stroke and larger valves than current 450 and it was running better than any KTM 450 Hmmmmm nsman you might have healthy running 450
Happy trails VIKING
