1977 CB400/4 Supersport Stock Exhaust Weight??

[robnobrakes]

Has anyone weighed their stock CB400F1 exhaust.  I would be interested in the comparison with my after market exhaust weighing in at 3.4Kg.

No idea but looking at the price NOS systems go for they must be worth their weight in gold.

 .....get it! Fnaaaaah!

You didn't expect an answer to that question did you?

Oh ok then. Stock F2 exhaust :
Silencer: 2.4kg
Downpipes/collector: 4.4kg

I assume F1 is the same.

Brilliant - Many thanks.

Total weight loss now 19.6Kg (including the new parts going back on)
