Hello Nick,

Oil in Frame (OIF) refers to post 1971 Triumphs and BSAs when the separate oil tank for the dry sump Triumph/BSA 650 engines was replaced with a frame using a large diameter tube backbone type where the oil is carried inside the main large frame tube.

Cheers Geoff

The oil in frame models weren't well liked. The seat height was higher. I read in Classic Bike that there was also a problem of debris in the oil tank as these weren't typically cleaned out properly.

1973 and later OIF have a lower seat height. The big backbone of the frame makes for a fine handling bike. They are less popular than the earlier models (i.e. a bit cheaper) but by no means a bad bike. Plenty of them about too.

Plus, they only hold about 4 pints, which, couple with their copious oil leakages, means that you live in constant fear of over heating your engine ;)

Add an external spin on filter & it gives an extra pint(ish) capacity, as I'm sure you know.

I wonder how much those Norton catapiller oil coolers hold, seens lots of Trumpets with them fitted.

everybody who has never ridden an OIF bike trotts out the " they don't have a big enough oil tank and run hot" rubbish

they don't run hot, the frame is an oil cooler. They run cooler that the dry frame bikes

I have a Norton spin on filter and a Hyde 'bog brush' cooler, which adds plenty to capacity. The 'running hot' problem occurs after Ye Olde Oil leakes have allowed a good portion of the lubricant to escape to atmosphere, sure one can top it up again at each stop, but that requires carrying a bottle of Castrols finest with you, either that or 'sort out the leaks'.... :lol:
