Chirpy's suggestion to rent a U-Haul bike trailer sounds ideal for a one-time project. However, buying the tools needed to haul your bike in the back of your truck (a ramp, 4 ratchet tie downs and 2 nylon loops) will allow you to transport it quickly and easily whenever you want.
To safely load and unload a bike into a truck when you're on your own, you'll need to use a strong, wide ramp that allows you to ride on/off, and also provides the ability to put your feet down on it to steady yourself. Good, wide folding ramps of the size you'll want start at about $130.00 or so.
To begin, lay the ramp on the lip of the open tailgate and secure it to the rear bumper with one of the ratchet tie-downs to prevent the possibility of it slipping off, then ride up into the truck. Once the bike is on the truck, a sturdy front wheel chock is ideal for positioning it straight and securely in the bed, but isn't an absolute necessity. Instead of using a wheel chock, I simply angle my bike diagonally across the bed of the truck and push its front wheel snug into the forward passenger-side corner of the bed, then lean it over on the kickstand before attaching any of the tie-downs. I'm careful not to put an excessive amount of tension on the tie-downs that are on the same side as the kickstand, as too much force pulling on the stand might bend or break it.
I use a pair of figure-8 nylon loops wrapped around each of the fork tubes just above the lower triple clamp as the forward tie-down attachment points on the bike. To those, I attach a ratchet tie-down on the right side to pull the fork down into the forward passenger-side corner of the bed, and a ratchet tie-down on the left attaches to the corresponding point on the drivers-side of the bed. I also tie down the rear of the bike on both sides using either the passenger footpeg mounts or the exposed seat frame rails. After driving for 15 or 20 minutes with the bike in the back of the truck, pull over, get out and check the tension on all of the ratchet tie-downs and snug up any that might have developed slack.
If you currently have a bike, practice loading and securing it a couple of times to get a better idea of the procedure. It's probably best that you don't do it cold for the very first time with your brand-new Speed Triple.
My method isn't the only way to do the job, nor will I claim that it's the best way, but it works well for me.
