Some builders do not live in the real world, likely for looks only. Could be an intentionally limited travel setup and it would not handle for crap like that. A looks only thing. Normal front end travel is more than that, a hard panic brake will use twice as much as what you got there. Damped and limited to use only what you got there and it would ride like a rock, you'd feel every bump and your arms would not like that after minutes.
The super big front tire will have heavy gyro action and not want to turn off line at speed either. If the rear hoop under the rear ducktail joins both sides of frame rails in back then the rear tire will strike hoop before full travel too.
Ain't no way anybody driving that thing fast at all except on dead level super smooth highway. At least if he's smart.
Look at all the choppers that are built with no possible realistic using of them. For looks only.
