Iowa Administrative Code › Agency 761 - Transportation Department › Vehicles › Chapter 450 - Motor Vehicle Equipment › Rule 761-450.4 - Minimum Requirements for Constructing and Equipping Specially Constructed or Reconstructed Motorcycles or Motorized Bicycles

Current through Register Vol. 47, No. 3, July 24, 2024
Minimum requirements for constructing and equipping specially
				  constructed or reconstructed motorcycles or motorized bicycles as defined in
				  Iowa Code section
				  321.1
				  are as follows:
(1)
Application.
As outlined in rule
				761-400.16 (321), the applicant
				shall submit the required application forms and exhibits to the county
				treasurer. The vehicle and ownership documents shall be examined by the
				department. If the department determines that the motor vehicle complies with
				this rule, that the integral parts and components have been identified as to
				ownership, and that the application forms have been completed properly, the
				department shall assign an identification number to the vehicle and certify
				that the motor vehicle is eligible for titling and registration. If the frame
				specified on an application for a specially constructed or reconstructed
				motorcycle or motorized bicycle is designated "not for highway use," the
				application shall not be approved. The exchange of compatible body parts does
				not constitute a specially constructed or reconstructed motorcycle or motorized
				bicycle. The removal, addition, or substitution of a reconstructed motorcycle
				or motorized bicycle part that modifies the vehicle's external appearance so
				that it does not reflect the original make or manufacturer model does
				constitute a specially constructed, reconstructed, street rod, or replica
				motorcycle or motorized bicycle. EXEMPTION: The conversion of a manufactured
				motorcycle from two wheels to three-wheel operation by the addition or
				substitution of a bolt-on conversion kit shall not constitute a reconstructed
				motorcycle.
(2)
Upgrade

-
minimum speed.
No motor vehicle or
				combination of vehicles which cannot proceed up a 3 percent grade, on dry
				concrete pavement, at a minimum speed of 20 miles per hour, shall be operated
				upon the highways of this state.
(3)
Engine.
Rescinded IAB
				9/8/10, effective 10/13/10.
(4)
Frame/chassis.
A motorcycle or motorized bicycle
				frame/chassis, including the suspension components and engine mountings, shall
				be of sufficient strength, capable of supporting the combined weight of all
				vehicle components and riders for which the vehicle was designed.
(5)
Front end assembly.
a.
Trail (extendedfork measured in
				inches).
No reconstructed or specially constructed motorcycle or
				motorized bicycle shall have the front fork so extended as to place the center
				of the front wheel axle farther than 36 inches from a vertical plane through
				the steering axis.
b.
Rake
				(extended fork measured in degrees).
No reconstructed or specially
				constructed motorcycle or motorized bicycle shall have the front fork so
				extended as to exceed a 45-degree angle between the fork assembly and a
				vertical plane through the steering axis.
c.
Extensions.
No
				reconstructed or specially constructed motorcycle or motorized bicycle shall be
				equipped with extension slugs. However, one-piece extension tubes and springer
				units, if approved, are acceptable.
d.
Wheelbase.
No
				reconstructed or specially constructed motorcycle or motorized bicycle shall
				have an overall wheelbase, measured from the center of the front axle to the
				center of the rear axle, of less than 40 inches.
e.
Motorcycle front end
				geometry.
A representation of the front end geometry of a motorcycle
				is depicted in the Appendix to this rule.
