Hey gents, specifically looking for an answer from Aus, I haven't checked with the specific state legislation yet, however does anyone know what the requirements are for reducing the length of the frame please? I'm undertaking a project and want to install a single seat..
Cheers..
I'm so glad we don't have to worry about that crap in South Africa.
Lol I think with the downsides to laws and regulations comes order and safety, or at least a legal accountability a place like South Africa wouldn't have.
Yo FJ1200, where in Aus are you? I'm in Brisbane. A cut frame is no longer road worthy, full stop. Do a good job and if your bike falls off rego you might find a mechanic that will do you one but that is besides the legality of cutting the metal frame that is holding your bike together, structural importance of the tail not equated into that rule. I recently got defected and while I don't have a cut tail they mentioned tail tidy. So I think their main concern is rocks fly off the wheels and a cut tail won't prevent that but a swing arm mounted m-guard will. I'm not cutting my tail because I've found a sexy way to lower the seat and mould the stock seat to fit more narrow.. (fyi, that's an option)

Haven't come across the term "legal accountability" over here in a very long time. It works both ways though. Yes, we have a lot of freedom, but should the pawpaw hit the fan, you're on your own.
What do you mean by "requirement?" Legal requirements? Engineering requirements?
I would also check with your insurance company to be sure you are okay with the rate increase on a modified frame. I know mine asks if the frame has been modified.
Legal and engineering requirements for frame alterations are one in the same in this instance. Below is taken from the QLD TMR. Mudguard/tailtidy is also required if cutting the frame, hence my previous mention of a workaround. Info for heights and angles is more spread out for that but basically your wheels can't chance flicking rocks back.

Frame and suspension alterations
Modifications to a motorcycle frame or suspension 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.
Motorcycles with properly designed custom frames, extended forks, hard tail or mono-shock conversions and structural modifications require an engineer's report to be submitted for approval by the Department of Transport and Main Roads. You must engage the services of an Approved Person Engineer with the LO1 code before starting the modifications. Find an approved person in your area.
