I'm a little bored this eve, so I've just worked out my top speed approaching Avon Rise...
Assumptions/errors:
The needle was waving around the 9000rpm mark, so I've used 9000 for the calc;
Can't account for the expansion of the rear tyre due to centrifugal 'fling' cos I didn't fancy leaning over to measure it!
So the number is tending towards the low side.
top speed = 121.0463mph
now I'm bored again.
