Before you jump whole hog onto the trike-bandwagon with this beauty, there are a few fine points from the eBay listing that need some focus (ALLCAPs are seller's, not mine): ALL CUSTOM - *NOT A KIT* MUST HAVE SOME TYPE OF ENGINEERING KNOWLEDGE TO COMPLETE YOURSELF! RIDDEN LESS THAN A MILE DUE TO IT BEING SO LOW TO THE GROUND* AS WITH ALL CONCEPT VEHICLES THERE WILL BE QUIRKS TO WORK OUT AS MORE DRIVING TIME OCCURS.
It appears that someone has built a custom steel/carbon fiber chassis with the rear section from a 2007 Honda CBR 1000RR. That means you get a 1.0 liter inline-4 good for 172 horsepower at 11,500 rpm mated to a cassette type close-ratio 6-speed gearbox without a reverse gear.
