Well Dave, I can at least say I would have DEFINITELY spent that addition $2500 for a near 1000cc engined(putting out around 70 to 75 ponies), and upgraded suspension(with maybe fully adjustable for both pre-load and rebound)units, for a bike that looks like the one I have now, which at a grand total of just over $10K would STILL comparable in price to a H-D 1200cc Sportster or a Ducati retro-styled GT1000.
(...yep, I would have alright!)
