  • Rego with larger cc engines

    Hi all,

    I plan on building a custom bike and was wondering is there any links or threads I should read to help me understand what is needed and what I can and can't do to pass a roadworthy?

    For example, is a exhaust and can that sits under the engine ok?

    Also what size engine can I get away with? For example I'm guessing I can't just throw a Daytona 190cc in it and pass with out a worry

    Any info would be greatly appreciated

        Hi Saint, welcome to the forum. If you are taking the bike to a place that doesnt understand monkeys, then the less mods from standard is better. I have a RWC license so I can help you when the time comes.
        General rule of thumb is that you can get away with minor mods like exhaust, bigger carby etc. If you are fitting a bore up kit - no one has to know whats inside your engine. Ive even seen Chinese 125s & 140s go through without any hassles.
        (after all, they're all 49cc aren't they!)

            Hi Saint

            Contact your insurance company and ask their opinion as well, if you have an accident with the wrong set-up it could cost you a fortune.

            Here is some info from VicRoads:

                Why ? Not enough ground clearance ? Too loud ? How many db's if too loud ?

                  General rule here is if it's legal it should be ok, if it's not they can knock back claims - it's all up to what company you are with and their customer focus.

                  All that said ALWAYS let them know and get it noted to your policy.

                  I speak with over 10 years of General Insurance industry experience and currently I am working in legislation interpretation. Happy to talk offline about anything you need to know.

                    My interpretation of the below clause is that is the insurer would have charged you a higher premium but still covered you, then you are still covered and liable for the increased premium, if they would have refused to cover you at all, had they known, then you might be in trouble:

                      Hey Mr Anderson. The problem with the ICA is its is "interpreted" by insurance companies and they will all fall back on internal Underwriting Guidelines to back themselves. IE you need to let them underwrite your risk and accept or decline it PRE claim.

                        Sorry for the high jack. This thread is about rego not insurance - they are 2 different things.
