LOL as if anything you say about any other bike than your wr450 matters. u admittedly have no experience on anything but that bike in the last 25 years. that 350 would run circles around your wr frankenbike. Oh, and by the way: 39 bikes since 1999 Riding since 1971 ! There is NO SUCH THING as a great stock bike. They all suck in one way or another and must be upgraded/adpated to the rider/situation. ...unless of course you suck as a rider, or if you are an expert, don't mind wearing out a bike in one race. Your precious KTM bikes used by Pros have just as much money spent on them (about $40k for SX, about $20k for offroad) as any other brand, to make them competitive at a professional level.
