Summary of changes.


Both 450 and 250 feature for the first time in a mass-production machine, a new high-performance piston with bridged-box bottom, the same design as the factory racers.

The KX450 features a reprogramable ECU via an optional kit. The exhaust has been shortened on the 450 for better md range.

Both machines have new thicker, wider radiators with more widely spaced cores/fins These are stronger, offer better resistance to mud build-up while maintaining cooling performance. Also they are lighter overall, making reinforcing brackets unnecessary.

Suspensions have had a rework, new steering head, and swingarms for both bikes. The 250 sports Showa titanium twin chamber units at the front. The bigger machine has a pair of Kayaba DLC. (Diamond-like Carbon coating)

Petal style lightened disc rotors feature, along with revised spring rates, and altered linkage rates for precise handling.
