You can do what I did, sold my DRZ400SM for a Beta 520 and saved 50 lbs! As far as a carrier, I'm happy with this
Tilt A Rack which I use on the rear receiver. At each end, I make some 1/8" cables with quick release turn buckles to help stabilize the rack, which works well. This rack has the added bonus of an attached ramp so nothing additional to store. You might get in touch with skipro3, he carries his dirt bike on this rack on the front of his TC and might have some pointers. Don't leave home without your bike!
