I didn't have speedo, but was a total handful, but brilliant fun.
It sat very low at the back, sometimes getting a little swamped over the back when slowing down.
I washed out the engine after the stuff sold the engine for £600, the sold the cub and trailer for £350, should av kept it.
Does anyone know why Cougar built these?
How many were made?
Is your 25 a S/S as this is what is required on a Cub.
