Without the speed burner and x-buster upgrade, you can get the heart container in OO's stage. I've done it, so I know it works. After you crash your bike on the machine that makes the sand storm, go ahead a little and knock down all the small pillars before the structure at the top of the cliff.

After that, go back and get the bike again. While on the bike, if you hit the dash button right before one of the ramps created by the knocked over pillars, you'll get some serious air. Do this dash on the last ramp and you can make it up to the top of the cliff. If you knocked down all of the small pillars before the structure at the top of the cliff, you can keep your bike.

When you arrive at the structure, there is a hole that you can get over by dashing while still on the slanted part. Do this and go straight until you land on the platform with spikes. Go across the platform on the bike and turn at the last second before you crash into the wall of spikes. This will get you the heart container with a bit of skill and luck, instead of needing the Speed Burner and the Xbuster and Leg Mods.
