    So I have studied the forums , followed in great detail the various US and Canadian builds on this mid sized adventure bike and it's time to bite the bullet.

    I bought the bike and the CB500R engine has arrived

    both bike and engine are 2014

    and the wish is for a finished product something like this but with the 500cc parallel twin

    Subscribed. Best of luck with the project. Too ham fisted myself to take this on, but I’ve no doubt your final product will be amazing.

    Is this going to be engineered and registered?

    Not wanting to rain on your parade, but the engine they sent you looks a lot like a wooden box with a dog standing on top of it?... You may want to get in touch with the supplier!

    I'm itching for a conversion of some kind so would like to find out how hard it is to have these two things done, if so.

    There is much information in the web and the US and Canadian guys are super helpful, fast response and supportive , I will take a few measurements so there I is a bit more technical info to follow but most of the builds are slightly different. The beauty of the Cbr500r is the sprocket and throttle bodies are in the right spot and it fits without too much modification to the frame

    Oh I've read the CRF500L builds in here JB and can do it but just wondering about the legal side of it and the associated costs (engineering) here in Aus.

    AFAIK, in NSW it goes something like this:
    A Honda engine into a Honda frame, any capacity, no problems, as long as you don't alter the frame (new bracketry is OK).

    I came up against this when getting a registration inspection for a bike with an engine from a different model (same capacity and configuration, but from a CB rather than a GL). The inspector said "if it's the same brand and it fits, and you haven't chopped up the frame, then you can put whatever size or type of engine you like in there"

    Subscribed. What a great combination!

    Any idea what final weight and hp will be?

    In regards to registration - it's all too hard and too expensive so it will be under the radar - I understand that this will make it unsalable but it's probably my last adventure bike.

    It's likely to weight about 150-160 kgs and the Cbr500r apparently puts out 47hp with a 6 speed box , the plan is for a tame mid sized adventure bike with good fuel economy and range.

    Probably the most important thing is the smoothness over a dirt single that would have you buzzing at 100klm’s distance.

    Fully understand that approach, they make it far too tough (nanny state) otherwise.

    Bloody hell JB :eek2, will it last another 30 years? Don't forget, adventure riding is an old mans game, if the demographics are to be believed....
