I'm considering buying an old Yamaha off of a friend of mine, but neither he nor I know much about the bike. He thinks it is from the 70s and it is a 250cc 4-stroke bike. Hopefully someone can help identify this thing.

Hopefully the links work.

Thanks!

xs 360 would be my guess

heres a pic & no its not me or mine.

I agree, it is an XS3602D from 1977. It is the economy model with wire wheels and drum brakes.

Awesome, thanks for all your help!
