The SPARK is only around 400lbs, empty. I have a KAW TS650 (SAME weight) for 22 years and never had a problem pulling it up on the trailer.
The Spark sits flat on the 2 rails, and I use several "O" rings to tie the front to a support bar (Keeps it from sliding backward). My plan is to add a "large rubber V" to the support bar, so I can drive it it to a touch point, and then tie it off.
