G'day viewers I know it's not VMX but someone out there will know. Is this fork spacer standed for a 750 Bonnie 1977. I'm just pulling the fork tubes out to replace them due to bad rust. Thanks jimson

I found a online manual with forks in break down view .
But it didn't show a spacer , but showed the top cap in to bits like they screw apart will send you a pic .

That spacer is not standard on a T140 1977, it may have been added to beef up the springs a little.
standard fork tube length is 555mm
standard spring length 485mm
The top nut should be in two parts, top hex nut in steel with the other part made out of alloy.
If you remove the top nut you will find it has an allen key hex inside, normally the chrome instrument bracket is mounted between this two nuts. (hope that makes sense).

67Lacrosse it would appear the nut is one piece & is all alloy. Maybe it's not standed. Jimson

Hi Jimson
The one piece nut was used on the 1971-1972 Triumph and BSA models with front conical hubs and originally made from steel, however there are new ones made from alloy these days like yours. They will all do the same job as they have the same thread size.
