I have seen them on pictures of old desert sleds, but I have never found them in a catalog.
I know they are not OEM for Triumph.
My T100 has a set on it but I need a set for my 650 Bonnie I am planning on racing in the desert with.
It has high straight pipes on it now but before I fabricate heat shields and weld on spark arrestors on I would like to try to find pipes like these.
They don't burn modern riding gear up as easy. :eek:
I will do some research and get back to you later...
Derek used to have a cherry one that he raced ahrma.
Betor forks, rickman primary cover, single carb head...
BTW, Kibblewhite Precision machine is reproducing their high lift tappet blocks out of ampco45 bronze, so you don't have to modify the cast iron ones for high lift cams, or if you are running a Al big bore cyl.
