Thanks Jerry for your comment. Apparently my bike is only $100 more than an undocumented GZ250 MSRP. My low mileages 2009 includes nice extras, including a "Pro Pad" seat pad I didn't mention, and CA legal. I remember seeing left over unsold New Jersey gz250 2010s back in the day for a low cost, but not in SoCal. One cannot register a "vehicle" in CA unless it's CARB certified for CA (decals and frame/engine VIN) or has > 7500 miles used. Sell your low mileage 49 state vehicle (car/moto) before moving to CA
