I've had plenty of SRAD 750's and currently have a k2 750 for sale. Friend of mine has a SRAD6.

What bikes are you used to riding?

I love Suzuki's, build quality isn't the best, but I just love the way they ride.

As for things to look for, crash damage is the big one, the people who tend to buy these tend to ride them hard, the other issue with these are the cam chain tensioners letting go, so make sure the engine is very quiet and smooth and starts easily and idles well.

How much are you looking to spend?
