16yo, 6 1, 165lbs, help picking a dirt bike?

M a guy, 16, 6 1", and 165lbs. I'm getting a dirt bike for trail riding and riding around lake pleasant here in Arizona and I think I've narrowed my choices down to the honda Crf230f and the crf250x. Any ideas? Price isn't really an issue.

Your mom is my favorite dirt bike

At your size, I think the CRF 230 might be a bit small for you, the 250x would be a better choice. The 230 is a fantastic trail bike, but sits closer to the ground than most other bikes making it a better choice for those in the mid 5' range. I would recommend going down to Kawasaki and checking out their KX 250F. The Yamaha WR 250 would suit your needs well also. Yamaha's YZ 250fx is also quite comparable to the CRF 250x. To be honest, there's not really all that big of differences between the brands except color. All are solid, dependable bikes. Maintenance is pretty similar on all… Some a little easier to work on… But that can become subjective quickly.
I have a 230f in my stable and I'm not talking bad about it, but the 230f is ONLY a trail bike whereas the other ones listed are comfortable on the trails, but are also performance based. Many people also make their WR 250's street legal as its wide ratio transmission seems to make it a better candidate for a dual sport than the others. Something to think about.
Go down to a dealership that sells multiple brands and see how they feel under you before making any decision… Or go with whatever color suits you the best… Just don't get hung up on brand, there's just not that big of a difference.

The crf250x has electric start.
Electric start comes in handy when you're stuck in the mud.
It also has a headlight, which comes in handy during overcast days.
Those might be deciding factors for trail riding.
