125-200cc What is a 06 WR125 worth?

I am probably just going to trade in my WR125 but I am wondering about what it is worth. With the 09 going for 4k I have a feeling the value of my 06 is low. I am thinking it would be worth around 2k if perfect and mine is not so probably only about $1700. Does that sound about right? I am afraid it is worth so little that I would just keep it if I were not getting another 125.

Here is a description.

06 WR125 (07 plastic)
Springs for 185 - 200 pound rider)
PWK
TC 2
New top end not too long ago
Bearings, brakes, chain and such all kept in good shape.
Skid plate

The bike does not have a ton of tiime on it but I ride in a lot of tight bushy stuff so cosmetically it is far from perfect.

Sounds like a good guess to me. Most 125's in my area go for 1,200-2500 used.
