Pretty universal long seat for anything you're willing to mount it on. Nice budget option for top tank conversions. We've seen these look pretty good on a custom Sachs G3 and a Hobbit. Would make a sweet back rest for your chopper build too!
18 inces long, 9 inches wide, 3.5 inches tall, and 5.5 inches tall at the rear.
There are 4 mounts that are 14 inches from front to back and 6 inches wide.
