This is an excellent model. One of the best that I have printed and put together. Though it doesn't say in the description, it is in perfect 1/12th scale. The suspension description also leaves out the the rear suspension will take a pen spring to add to the incredible rear detail. The swing arm is print in place and has suspension travel. The front forks take another pen spring, which I cut in half and unwound a little to soften the spring rate. Some details to note, the wheel spokes are incredibly fragile, put the sprocket and disk on a table and press the wheel hub into the disks. The battery is difficult to slide in from the top, it isn't coming back out, in case you plan to paint it. Printing it at 90% scale would help. I printed 4 brake disks and 2 sprockets for the street and dirt tires.
