Correct.. the mileage readin is out by the same amount
100,000 miles ?? Peanuts.. try in excess of a million miles now !
Re the top speed difference and the tests..
Cos the tests are done by people who do not really know their arse from their elbow most of the time !
We, the owners, are the only true testers
And that figure.. it is fantasy land I am afraid.. A stock xx will produce 133 to 135Bh at the rear wheel.. the only place it matters
The difference in top speed is where and and how the power is produced.
For instance, a Triumph Rocket 3 has a torque figure in excess of 120 ft lbs.
It can pull tree stumps !
Yet it runs out of puff by about 120ishMPH ( I believe )
To have a high top speed the engine needs to produce good power fairly high up the rev range.. other wise it simply runs out of puff..
If ever you want to do a top speed run on your bike always take it right to the red line in 4th and 5th.. it is the only way to get it up there !
