I can speak from experience as I ride my father's 1934 KSS Velocette with a girder and it is a tank slapper waiting to happen because the girder links push the axle forwards so much.

A secondary (though to me major) benefit is an increase in trail which with a short girder is minimal bordering on dangerous. Angle the girder forks back (ie the axle) to achieve 550 by moving either the bottom link triple tree mount back or the top link triple tree mount forwards the appropriate amount. Did it come from Oz or the states?Ī suggestion re 550 Ridikulus Rool. Outasight man! Knowing you it will be a righteous rigid chop when you are finished. I do have a complete spool hub/drum brake rear wheel on it's way from the states, and once that arrives will worry about a front wheel and getting the roller all together and start with engineering. This isn't the gas tank I'll be using as we plan to fab ALL the tins for this bike, but I was stoked to get this tank back off my previous Chopper and this is a good place to store it for now.

I think this frame has been passed around long enough, and now deserves to become a bike again.Īs you can see I've since acquired a 6" stretch and 2.5" hardtail for it, and a complete engine/gear box from a 1971 Triumph T120R.Īnd more recently I've got my hands on a 2" over P&P Girder front end, which will require some frame modification to fit within the 550mm rule for rego. It's a 1965 Triumph Thunderbird frame and the numbers are good for rego.

The start was getting hold of this front frame loop which an acquaintance picked up at the Northam Swap meet many years ago, and has passed through the hands of three other people I know before I got my hands on it. From there things should progress more quickly. Yes I'm back to my old tricks of putting another rigid Chopper together, but this time starting from scratch.Īt this stage I'm just collecting the hard to get major parts, with the hope of having a roller together by the end of this year.
