Another friend is looking to get back on a trial bike and he found a 2003 Beta Rev 250. I will go and have a look at it with him later this week, any advise on what to look for?

Thank you in advance.

Check the watter pump, the stock covers can be corroded by the coolent if it isn't the correct type and often need to be replaced/repaired. 

 

If the owner doesn't know if its replaced/repaired and will not let you pull the cover to check you will need to double check if the oil has water in it and when the bike is hot the radiator is getting hot and the fan comes on correctly. 

 

Bad cover = water in oil, or no water flow to the radiator and cold radiator but hot engine.

 

everything else should be about the same for any older bike, barring play, brake fluid, clutch working, runs well, etc.

 

best of luck.
