I may be picking up this bad boy by Easter...

Trading my old run down boat for it. Anybody know anything about CR125r's?
The guy sent me a list of mods that he's done:
Racing Top End
VP Reeds
Racing Suspension
Pro Grips
Gold series Fatty with Power Core 2 Exhaust
2013 Monster Graphics
Excel Rims.

My problem is I know nothing about dirt bikes. I'm trying to learn before I get too deep in this thing...
