1. gas sits lower
2. almost no flywheel weight (and almost no torque, either)
3. you sit farther forward
4. lower effective center of gravity
If you pick both bikes from laying on their side, they feel about the same, but leaning them only 20 degrees, the KTM is lighter, and when moving, it has such soft torque (no flywheel) that directional changes (gyroscopic effect) is reduced substantially.
Next would be the battery change to Lithium iOn
Next would be lowering the radiators with a Zipty kit
Beyond that, there are no signifigant parts on the bike that you can remove that will save any real weight, other than an after market exhaust and kickstand.

A 250 is a lot lighter than a 450. But your suspension being sacked out might make the bike have a heavy feeling. Get the suspension redone by racetech or someone that gets rid of the stock base valves in the forks.
...oh yeah, that is kind of an important point.
That 250 is about 236 and the 450 is about 270. So it should feel quite a bit heavier.
Not an apples to apples comparison, either.

Check your sag on the rear shock and move your fork tubes up a little. This will help in the geometry of the bike. I have an 04 WR and 13 KTM 500 EXC. They weigh the same, but the KTM is more nimble due to the geometry of the bike. That is why the bike feels lighter. You can only do so much. The WR is far better bike on the high speed open stuff because it is more stable, due to the longer fork rake.
