    Aww that’s a bit flash. Comes with a motor & fairings as well.

    Besides, isn’t against the spirit of things to use an racing chassis?

    Against the rules too, I believe...
    And I to my motorcycle parked like the soul of the junkyard. Restored, a bicycle fleshed with power, and tore off. Up Highway 106 continually drunk on the wind in my mouth. Wringing the handlebar for speed, wild to be wreckage forever.

    Actually chassis is free, but no competition internal motor parts are to be used

    I think the rules refer to competition engine and gearboxes. Frames are a free-for-all. Although not necessarily in the spirit of things.

    But if you do find some, or an RGV or similar rolling chassis, I'll have one.

    I thought it would be a nice frame to put some hot 4 stroke motocross motor into and race in F3 like that Tigcraft of Jason Eastons.

    So what would be a good bucket motor?

    Virtually nothing fits in an early RS125 chassis. Due to the shape of the CR125 motor the RS was based on, the gearbox output & the position of the rear shock are restrictive. You can get a 50 in, (requires quite some careful tinkering), but not a 100 without severe work. I've done this too, but what a mission & it still doesn't really fit.

    Later model RS might be easier, but they are worth real money.

    There's two with MB100 motors fitted to them in Chch and one of them didn't take to long to do

    top shock mount had to be modifed for carb clearance and fuel tank as well but apart from that the chassis didn't have to cut and shut much at all

    Hell's teeth! That's what I have (started 6 years ago).

    Needed to water cool it to get the barrel to clear & full case reed it to get the carb out of the way & cut a hell of a lot.

    With the std motor the carb is in the middle of the shock? Are they old canterlever chassis?

    Seen an RX125 in one I admit, but rubbish motor.

    Both frames are 90-91 era, one uses a downdraft 28mm flatside off a kr or tzr 250 and the other one moved the frame shock mount to one side and moding the bottom of the stock RS tank, this made possible by the ball joint type mount on the swingarm. Both are air cooled with only minor fin shaving one uses the head mount on the MB motor and the other uses the RS front mounts, both required lots of alloy welding so unless you have a TIG welder it is not a cheap project.
