02 vs 03 cr250

Recommended Posts

Don't think I've ever heard anyone say they prefer the '02 over an '03. Here is what motor changes were made (from here):

NEW FOR 2003:

New cylinder porting.

New eight-petal reed valve.

New air intake system offers straighter alignment to produce more direct airflow.

Redesigned number plate and inner duct.

New foam gasket between airbox and air boot for better sealing and airflow management.

New works-shaped expansion chamber.

New ignition timing settings help broaden the engine's powerband.


Air intake boot is reshaped for more direct airflow, contributing to strong low-speed engine performance.

Five-speed close-ratio transmission features thicker second and third gears.
