Where are you riding?
A 250 for east coast woods should be plenty of bike, and give you what you need for that area.
Out west, I'd be hard pressed to suggest a 250 because of all of the wide open spaces (and nutty drivers) especially in CA where you can lane split legally.
Are you committed to Suzuki?
Because.... a Yamaha WR250R costs only $200 more, weighs a good chunk less, will do just fine on the highways, get great gas mileage, has fuel injection, and will do much better on trails that the Suzukis.
I'd agree. For me, I needed a bigger bike for the open areas (think burning man desert) and the WR250R was my 2nd choice because of the wide ratio transmission, the price and the happy riders.
