Should I trade my 2005 Yamaha Banshee fully stock for a 2005 Honda CRF250?

[Steve-O]

Alright I need everyones help, should I trade my 2005 Yamaha Banshee 2-stroke fully stock for a 2005 Honda CRF-250 4-stroke? Are the CRF-250's good bikes? The CRF-250 has a hot cam and a stage 2 clutch and the stock clutch will come with it as well as plastic sides and a stand. I don't know if I should trade him. He wants to trade straight up. He hasn't ridden it in sand and he did tell me that he has wrecked it a few times but never broke anything on the bike so it makes me think he isn't lying. It has a fresh top end, he had it done about 2 weeks ago. He even says that if I get it, that I can go fast but I can't rap it up because its not broken in yet. He never raced it. But I don't know if I should trade because all we have here is sand and I think going from a four wheeler to a dirt bike will be hard. But with enough practice I should get the hang of it, don't you guys think. I have had a dirt bike but rode it in dirt and it was a small KLX 110 4-stroke. But since I think my four wheeler is worth a little more he is willing to drive 4 hours to bring it to me. What do you guys think or girls? Is the CRF-250 a good bike? Do they last long if you take care of them? I don't race just ride on weekends. He was selling his for $2,500 and I bought mine about a year ago for $3,500. Please help me ASAP. I want to know if I should trade him by this week.
