Interesting concept - the hydrostatic drive is like having a variable-ratio transmission.
This amazing machine got around 65-70 miles per gallon at 75mph in the Black Hills of South Dakota when it hit the road for the first time!!! Jeff finished building this motorcycle in the summer of 2004, just in time to bring it to the annual motorcycle rally in Sturgis SD. It performed perfectly!! He took it on several rides through the steep, Black Hills and was very pleased with it's performance. It got excellent mileage and had plenty of power to ride up the steep grades.
