Default Custom chopper frame for all predator sizes-designation Night Prowler



I spent a total of eight hours designing this frame. I used a 2D CAD software, so it takes a bit of imagination to see the two down tubes, and battery box for electric start engines. Total cost for fabrication: estimated $3500, including wheels, and cassette.

Add an outline of a real sized human being on the bike.
Knees will be hitting the bars which are so close to the rider it will
look like you doing the dog begging trick.

Why is the frame section so short?
Will be an evil handling bike with all that rake.....

version 1.5 has been replaced with an upgraded version.

The frame is longer, wheels are properly sized, and handlebars are where they should be. The frame is also taller, because I had the sizing way off for the 670cc V-Twin Predator. Gear ratio with a 1" 15t in 12t out jackshaft and a 12t clutch sprocket is 7.04:1. This gets me around 35-40 mph in first at 3500rpm with the 670. This is a touring bike, designed for long distances at interstate speeds.

This is version 2.1, complete with dimensions. You may have a bit of trouble deciphering the seemingly randomly placed numbers, but once you get the hang of it, its easy.
