Mark had his “swingarm of the Gods” well here’s the opposite, I’ve called it the “swingarm of No Gods”
Started with this
Then this
And ended up with this
Now for the questions/opinions
Would this swingarm be legal in pre 78?
Was it available prior to 1978 and can I provide documented proof?
Well the swingarm was available, it’s a 1976 XT500C swingarm and it’s had 4” added to it.
Consider, steel plate was available back then so were welding rods and welders.
Can I prove it existed? No, but how many of us modified swingarms and frames “back then”? I’ve never been one for photos, I probably modified 20-25 swingarms and a few less frames but can’t “prove” any of them (this is probably a blessing on some of the early efforts!) I did lengthen and brace several XT swingarms, mostly 2” but one was taken to 3”
If I turned up with this on my bike at a club meeting I wouldn’t expect too many problems but what if I turned up at the nationals? Are there any scrutineers form the Crystal Brook event or any other national who would have an opinion on this one.
