It started with a 2003 Road King Modified frame with 30* neck rake. Also HD Hydroglide fork brackets and 19" front wheel gives 5" of trail. I have ridden this to 155+ mph numerous times and it is very stable. I'm sure it is good for much more. The fuel tank is sectioned 2" for a lower profile. I have adapted Buell White Lightning wheels with ceramic wheel bearings to it. Clip on handle bars and rear set of footpegs. Chassis will accept an EVO engine and trans or a Twin Cam engine and Trans. Could be used as a Drag Bike with a lighter front end. I used it for Land Speed Racing, holds 9 records in Arkansas and 10 records in Ohio. I have Salvage Paper work but no title for street bike since I didn't use it that way.
