I rebuilt a Big Ruck for a friend about twelve years ago. It was non-op due to incomplete maintenance, it came partially disassembled and needed about $100 in parts. Worth it though; I think he paid $150 for it, which was a screaming deal. Took about an afternoon to get it back on the road.
Year model is easy to tell: the '05 models were yellow and the '06 models were silver.
As Tierney stated, performance is ... leisurely. The engine is an HF03E, a carbureted two-valve that makes about one horsepower more than a Helix. The Reflex had a different variator, but parts are otherwise similar.
Wind protection is non-existent. You're essentially riding on a girder with footboards. There were optional wind deflectors, but they were rare back then and that much harder to find now. The seat is the party piece. Riding with the backrest up nets you a small platform that you could lash a bag or milkcrate to. Otherwise, there's a cylindrical storage tube on the back right corner of the frame, suitable for a tool roll or a small bottle of wine.
Do not ride one with the side covers removed from the frame. Those scoops are critical to proper engine cooling.
The headlamps are great at night, but switch on without starting and it will flatten your battery relatively quickly if the scoot left on but not running.
The right lever applies the front brake and the left lever applies the front and rear brakes.
It's a unique looking scoot, but it's boring to ride. I don't understand the pricing aside from the relative "rarity"; the telling bit there is that few people were willing to buy them new and frankly, it was a whiff on Honda's part in addressing people's desire for a "Ruckus with More Power"; turned out that a GY6 swap made the original Ruckus much more palatable than the Big Ruck.
