TwinTrax is quite a simple, humble name for this stretched out motorcycle. Apart from the fact that the rider would lay almost flat on the motorcycle, and its killer looks, the big thing here is the motors it uses. TwinTrax uses dual Harley-Davidson/ S&S Evolution engines each at 1.35 liters and an output of 80hp. All that power comes with good reason, both those motors are pulling a combined weight of 400 kilos. It’s a good look but the stretch might be a bit too much to handle.
