How much weight do you guys think you could lose off of a 16 KTM 450? With another 3 pounds coming off next year with the air forks, that already makes for a very light bike. What else and how light do you think it could be? Light seat base and foam? Battery less electronics? Muffler of course. I know the teams run super light weight harnesses and battery's. How much weight would a Ti bolt kit take off? Ti rear spring, 50mil cone valves are supposed to be very light I'm not sure if they are lighter than the AERs. I'm sure you can lose weight from the motor internals. Ceramic bearings for wheels etc? Ti subframe, mods to the frame like losing brackets etc? Light weight brake calipers with Ti pistons? Most of that stuff is easy to come by but not all of it would be that cheap. But not crazy expensive . So a normal guy could probably get his bike way way under the AMA limit not that it means anything to most people. Seems like 10lbs would be easily doable. Would it be worth it if money was growing in the back of your van?
I would only be guessing as to how much weight you could save, perhaps an email to MXA might get you an answer as they know a lot about KTM's.
-3 AER Fork
-2 Full Ti exhaust
-1 light seat base and foam
-1 Ti pegs, random Ti bolts
-1 lightweight wheel set
You'd be in another $5,000 for that if the bike comes with AER fork.
If you realllyyyy had the money, and took weight off/out of the engine it would actually feel much lighter. DCR said he took 5lbs off a KTM 250SX-F motor.

And if you can figure out battery-less electric start that would be sweet.

As far as light weight motor, just a rough guess at a 5lb savings but kind of backed up by what CarlinoJoe mentioned. Light cleaned up cases, fly wheel, valve train system, piston, rod, crank, bearings, the head and cylinder themselves, light weight starter. All those grams from port work and polishing everything. Not to mention losing whole gears, and all the other ways to drop weight from a transmission.
I'm not exactly sure how much weight it is possible to lose but it seems like a lot is possible. I haven't even mentioned high dollar things like magnesium cases, throttle bodies, brake calipers, carbon gas tank, carbon air box etc, etc.
For me it's just interesting to think about, nothing serious just bullshitting with you guys. Cheers!!!!!
Of course they always make something lighter. I think Anti gravity has an even lighter battery plus a few other high end battery companies. I think the teams use some sort of RC battery.
I'd really like an engine nerd to chime in to what they do or can do... We've all seen the usual exterior bits and bobs but I'd have kinda thought the engine was a bit more no go for this sort of thing...
