    I tried that link and didn't get much, so I went direct to the QLD dept of TPT and they sent me a file with the below information.
    It's mostly general stuff and had a lot of car shit in it. But this might help someone.
    If you want a copy of the booklet, PM me with an e-mail address and I'll send it to ya.


    Section 3
    Specific
    modifications
    Modifications which are not covered by this booklet or
    the Approved Persons Scheme, or modifications which
    involve substantial structural changes to the body or
    chassis of a vehicle, require a written submission. A fee
    is payable for the evaluation of plans. Send submissions
    prior to commencing any modifications or alterations to:
    Policy Advice
    PO Box 673
    Fortitude Valley, Qld 4006.

    Applicants should supply as much detail as possible.
    Incomplete submissions, insufficient details or poor
    drawings will delay processing of submissions. As a
    guide, submissions should contain:
    • a completed ‘Motor Vehicle Modification Application’
    (Form No. F1854 available at Queensland Transport
    Customer Service Centres) and
    • drafted plans for any modifications or alterations
    involving structural changes. Plans, on A3 size
    drafting paper, should include dimensions, plan,
    elevation, end elevation and sections (where
    necessary), material description, and welding and
    machining details.

    A word of caution
    Modifying a vehicle for use on a road without obtaining
    prior approval, or permitting the use of a modified vehicle
    without approval, is a breach of Queensland legislation.
    If you modify a vehicle without the necessary approval,
    you could void your vehicle insurance and may be liable
    for prosecution.

    The permissible modifications outlined in this brochure
    have been developed in consultation with the vehicle
    manufacturers and industry.
    Click to download the Motor Vehicle Modification Application
    28 29

    Engine replacements
    Many manufacturers produce a series of models with the
    same basic frame fitted with engines of differing
    capacity. No approval is required if the smaller capacity
    engine is replaced by a larger capacity engine from the
    same series provided the brakes and suspension from the
    larger capacity motorbike are fitted and no modification
    is required to the frame.
    The fitting of any other alternative replacement engine,
    superchargers or turbochargers will require individual
    approval in accordance with Section 3.

    Steering gear and handle bars
    The handle bars of a motorbike must extend at least
    250mm, but not over 450mm, on each side of the
    longitudinal axis of the motorbike. This measurement
    does not include mirrors and lights.
    The lowest part of the hand grip on the handle bars
    must not be higher than 380mm above the attachment
    point of the handle bars to the motorbike. Hand grips on
    the handle bars must be fitted symmetrically.
    If the motorbike has the head stem as the steering pivot
    point, the horizontal distance from the midpoint between
    the head stem bearings to the centre of the front wheel
    must not be over 550mm.
    Offset triple clamps are often fitted to provide the
    motorbike with ‘a raked out’ appearance without the
    need to modify the frame. These are acceptable provided
    the trail measurement is not less than 75mm.

    Section 4
    Motorbike
    modifications

    Frame and suspension
    alterations
    Motorbike design is a complex task. Before modifications
    are made to a motorbike’s frame or suspension, you
    should be aware that structural changes to the frame,
    steering head, front forks, suspension, brakes or wheels
    may load vital components well beyond the limits for
    which they were originally designed. This may increase
    the probability of failure and may be a danger to the
    rider and other road users.
    Motorbikes with properly designed custom frames,
    extended forks, hard tail conversions and structural
    modifications are acceptable, but require specific
    approval as explained in Section 3. A report will be
    required from a Registered Professional Engineer
    detailing the changes and certifying that the motorbike
    is safe.
    30 31

    Seat reduction
    Compulsory Third Party (CTP) insurance premiums on
    motorbikes are determined by the seating capacity of the
    motorbike. Conversion of a motorbike from a
    two-seater to a single-seater, or vice versa, can be
    certified by an Approved Person as detailed in Section 2.
    For two-seats to single-seat conversion the maximum
    length of the upholstered section of the seat must be
    500mm or less, and the pillion foot pegs must be
    removed with any associated brackets and threaded
    holes drilled out. You are not permitted to use a
    removable cowl or other structure fitted over the seat
    to reduce the length of the seat. You should seek advice
    from an Approved Person before performing a seat
    reduction modification.

    Wheels and tyres
    On all wheels (including any side-car wheel), the tyre
    size must be suitable for the rim. Each tyre and rim must
    be strong enough to support the machine when it is fully
    loaded. Most major motorbike tyre specialists can tell
    you the right tyre and rim for your motorbike and the
    appropriate tyre speed rating.

    Chain guards
    If the motorbike has a chain drive, the driver and any
    passenger must be protected from the front sprocket
    and at least the upper part of the chain by the frame
    or equipment of the motorbike, or by a chain guard.
    A chain guard must cover the chain to a point at least
    300mm to the rear of the rearmost foot rest or above the
    centre of the rear drive sprocket.
    Motorbikes must be fitted with footrests for the rider,
    and for any passenger for whom a seating position is
    provided.

    Exhausts
    Motorbikes manufactured from 1 July 1975 are subject
    to ADR requirements for noise.
    Any replacement exhaust system must be as near as
    practicable to the original component specification
    and/or comply with ADR noise requirements.
    If you modify or replace an exhaust system on a
    pre-1975 motorbike, you must remember that the
    law prohibits all motor vehicles from causing excessive
    noise due to the condition or construction of the vehicle,
    or the manner in which it is operated.
    Motorbikes manufactured from 1 July 1988 have all
    components of the silencing system marked with the
    name or trade name of the manufacturer.
    These motorbikes carry information of the Stationary
    Noise Test in the following format:
    STATIONARY NOISE TEST INFORMATION
    Tested at............. dB(A) at........... r/min
    Silencing System: (manufacturer’s name)
    Identification: (trade description)
    Any replacement part of the silencing system must show
    the trademark or the name of the original manufacturer
    of the system.

    Mudguards
    Mudguards must be fitted to all wheels (including the
    sidecar wheel). Each mudguard must be at least as wide,
    over its entire length, as its respective tyre.
    A front mudguard must cover the rearward section of
    the wheel through the area between two lines, one
    vertical and the other horizontal, both drawn through
    the centre of the wheel. If suitable protection is afforded
    by the frame or construction of the motorbike, the front
    guard need only cover the unprotected area.
    The mudguard provided for the rear wheel and for the
    wheel of any sidecar must extend not less than from a
    point vertically above the foremost part of the wheel
    rearward to a point not higher than the intersection of
    the arc of the wheel guard with a line through the centre
    of the wheel at 45 degrees to a horizontal plane through
    the centre of the wheel.

    Indicators
    Indicators are required on all motorbikes manufactured
    after 30 June 1975.

    Sidecars
    Sidecars must be fitted to the left hand side of a
    motorbike. This does not apply to a motorbike and
    sidecar combination greater than 30 years of age.
    When a sidecar or side-box is attached to a motorbike
    manufactured after February 1976, a mechanical parking
    brake must be fitted.
    The maximum width of the combination, including any
    load and equipment, must not exceed 1.85m.

    Motortrikes
    Motortrikes that are constructed by removing the rear
    swing arm and substituting a suitable after market or
    self-constructed rear axle assembly and body work are
    considered to be a modified motorbike, if the motorbike is
    substantially unmodified forward of the swing arm pivot.
    The vehicle does not need to be updated to comply
    with current ADRs apart from those required as part
    of the trike conversion. For example, if the motorbike
    was not required to operate on unleaded fuel when
    manufactured, then it would not be required to be
    converted to run on unleaded fuel as part of the
    trike modification.
    The kit or owner designed and/or constructed assembly
    must be examined by an Approved Person with code
    LO1 to ensure it is suitable for the motorbike.
    You should contact an Approved Person as detailed in
    Section 2 about obtaining approval for this modification.

    Thanks for the Info fellahs!

    Not sure if everyone knows its now illegal to run an Orange Light here in Queensland, same fines as a red Light.

    http://www.transport.qld.gov.au/reso...l_14_02_07.pdf

    So if plod pulls you over and tells you that you just ran a red and you say no it was orange, you will get done!!

    Yearly Rego Inspection, what a pain! That was one thing we had over our NSW brothers.

    I thought the light was yellow.
    Does that mean if it changes to red after you enter the intersection but before you leave your guilty?

    Just an update as I'm starting to go through this at the minute. None of the links provided here are active but the information provided by Rocket is still valid.

    The guys that did the RWC today (failed first time) reckoned the single sided swing arm didn't need a mod plate, neither did the GSXR subframe, neither will the USD forks off a later model. Generally they gave the impression that if has come off an already ADR approved motorcycle it is all good and doesn't need a mod plate. Whether this is correct or not I don't know (it seems wrong to me) but at least I tried Mr Plod. A mod plate is required for single seat rego. Cost me $290 for 6 months dual seat rego today.

    Hi Mulder. Welcome to the psycho ward.
    Might be an idea to introduce yourself in the Welcome to the Madness thread. Ya might get flamed by some of the other members. Are you in Qld or NSW?
    As far as modifications to your bike in Qld, just use the COP for motorcycles. Not sure if its the same for NSW. Youre probably screwed either way.
