" The Oil in Frame was in fact designed by Rob North. ( under contract to Umberslade) "
And may he be forgiven for that !
Too tall in it's first incarnation , a filler cap in the wrong place [ see above pics] which meant that there was not enough oil in the tank .The filler cap should have been at the top ,near the sterring head .
The swing arm mountings flex and cause the frame backbone to crack and all the oil drips out .But at least Triumph carried on in their best tradition of producing bloody awful frames.
Blessed are the cracked, for they let in the light. - Spike Milligan
