Speedo accuracy hub vs gearbox

[hippie]

Just a question what would be more accurate in a stock standard bike with no mods at all ?
It would seem mine is fairly accurate if the solar signs on the side of the road are anything to go by?

Just remember that 2 k out at 50 is 4 at 100.
Most speedos read approx 100 when travel is 96 +-2
Changing tyre size and profile change things.
Gearbox type with sprocket changes would make a massive difference.

Tyres at different pressures and wheels at different speeds even changes the accuracy also. Tyres at 250kph can be 10mm taller than standing.

I changed sprockets and then had an error of 120 at a true100 kph. I had to correct it, it was too far out. Cost about 120$
