so at idle or cruise the oil at the dip stick doesn't fluctuates much? limited usefulness I suppose.

Not much difference. I guess if something went wrong the the temp would go way up. I was curious to see what the oil temp was on my W650 and am also curious to see what it is on the DF. I think you want the oil temp to be about 100 C or 212 F to remove the moisture out of the oil by converting it to vapor and and thus allowing it to exit via the crankcase vent.

Hey guys, I am new to this forum and I am thinking about purchasing a 2010 RTB 250 with about 2,000 miles on it and I was just wondering if these bikes experience a lot of problems? I have read a few reviews about the bike saying the motors are not very reliable so I was just wondering what problems any of you have experienced? Any feed back on the bike would be great. I'm hoping to get it for around 1,700.

Go back and read through this thread and take all posts with a grain of salt.

Would you consider 2000 miles to be a lot for one of these bikes?

No. One guy here has over 10,000 on his. Seriously, go back and read through the thread.

No.Just make sure you are ready to do your own repair work.There are no dealers around that works on them.Parts are usually easy to get from ebay or other websites that sell Chinese motorcycles.

I am currently reading through all of the pages of this forum but I am planning on picking the bike up this coming Sunday and I was just wondering if anyone could tell me some problems they have had that would prevent the bike from being rideable? Specifically any problems that have happened after the first couple thousand miles?

The 2010 DFs had a bad tank design which would leak if the mounting nuts were tightened too much. Some here replaced the tank.

They were jetted too lean which was easy to fix and the stock rear sprocket was a 45 tooth (like the 2012 DF) and needed to be changed to a 35 or so.

A lot of the problems in this thread were owner induced.

Like ben2go said you need to be able to turn a wrench or forget about buying a Chinese bike.

Is the bike you are buying in decent unbutchered shape?

They are under powered so don't expect cruising over 55 MPH.

This is the bike I am hoping to get. It looks like it is in good condition and it would be my first bike. Im not looking to go fast I mostly want it for just cruising around town. I work on my car a lot so I feel pretty confident that I can figure out how to fix any small issues. Thanks for the help.
