For sale is a 2003 yamaha with a 2004 125 engine in it. I bought the bike in 07 from a guy who's kid raced it. He said the replaced engine only had a few races on it. It has a hot rod crank and I rebuilt the top end years ago which prolly only has about 2-4 hours on it. Other upgrades include-FMF gold series SST race pipeFMF shorty silencer with TM exhaust collarCarb has been re-jettedRenthal handle barTurner clutch lever with quick adjust Vortex 50 tooth sprocket Excel rims Front and rear suspension was rebuilt and re-valved by lowe suspension ( By previous owner)Blue anodized Chain guideA brand new in box Barnett clutch ( not installed) I don't ride the bike anymore besides up and down the street or yard a couple times every year. I live in a suburb of Chicago so the only test ride you can do it up and down the street. If you have any questions. feel free to ask.
