From my understanding, the biggest weight savings were in the engine. Apparently the KTM 525 is a heck of a lot lighter than the fuji 500 engine. There may be some forged frame parts as well, but I'd be lying if I said for sure since I dont' really know, I just seem to recall having read something on it .. could have even been in ref. to a different machine [img]i/expressions/face-icon-small-confused.gif[/img] [img]i/expressions/face-icon-small-happy.gif[/img]
