Look away if you're scared of loose gravel
Get the weight on the back and get that front tire to plane!!
I think I dislike loamy soft dirt more....
Driving on the beach you encounter all kinds of conditions, hardpacked sand to softball sized round rocks. You can come around a slight bend and the sand changes consistency, or ridges of gravel have formed, some places are soft clay or even composting seaweed covered by a shallow layer of sand where you immediately sink about 6 inches into the muck as it tries to grab your wheels. As RR says, in most cases get far back and keep the front wheel light.
Another thing is to time all your travels with the tides as you can run out of beach in many places once the water comes back in, plus the sand is always wetter and harder when the tide is falling. On our last outing it was super low due to the sun/moon/earth alignments so I was riding on new sandbars I've never even seen exposed before.
We also did a fair amount of two-up riding with the DRZ as it has passenger pegs (it really is a fun and versatile machine). It was
much harder riding on the beach with a passenger, even an excellent one like Lynn. I had changed the tires to more street worthy and they gave up something off-road. At times I felt like we were skiing where you tried to pick your lines and hoped the bike would either turn or stay straight, but you had to go with the flow and bounce around the moguls, or in this case, the mounds of gravel on the sloped beach. We gave up trying to get to one point when we ended up spinning almost completely around when the rear end slid out sideways on the stones.
The beach is always changing, I've never seen these sandbars before this year.
