Your guess is as good as mine.

I would guess it means all of the engine weight is more compact, giving the designers better control on exactly where the C.G is (center of gravity) which equals better handling.

Do any of the other 450s come stock with titanium valves?

All 5 on the yfz are ti and the intake valves and the 06 450R are also.

All of the grears in the transmission are generally help seperately behind the crank case, in sequence.

I assume for the LTR the first two gears are placed somewhere outside of the mian gear cluster so the transmission doesnt have to be as wide or bulky.
