All that is done to the bike is i have a 41 tooth rear sprocket. No i dont have a picture or anything to show that thats what the speedo said but thats where it was.
Busa Speed Calc Tool
The error is different at different speeds.
One way to determine the error is with a GPS. Note the speed on the speedo at say 70mph the note the GPS speed. The difference between the two is the error at 70mph. Do this for 80, 90, 100, etc. Then you can determine whether the error increases with speed or not. Good ol' imperical test will net you the most accurate results.
You can also calculate how fast your bike should theoretically go at a given RPM in a given gear with a given final drive ratio (the chain and sprockets are the final ratio).
Here's the ratio's of a stock busa.
Primary = 1.596 (83/52)
1st = 2.615 (34/13)
2nd = 1.937 (31/16)
3rd = 1.526 (29/19)
4th = 1.285 (27/21)
5th = 1.136 (25/22)
6th = 1.043 (24/23)
Final = 2.352 (40/17)
You need to pick an RPM most probably the rev limiter 10,800 RPM.
...and you'll need the circumference of the rear wheel.

Thats not bad. Im impressed i guess i could say for a stock bike. So the speedo at that speed is roughly about 24 mph off. Atleast i know i was somewhat close to 200 mph. I wonder if i change the gear, if the motor will have enough to push it passed 200 mph? Maybe ill do like a 38 tooth rear!

ok thanx for everyones responses yea i found out bout the smart t.r.e that i have to get cuz the regular one stays the gear indicator in 5th but umm now i have bigger problems so u can find me in a new post...
thanx bobby

NOT the "Smart TRE"... that one is just switchable (On / Off).
You want the "Intelligent TRE"... that's the one that allows you to maintain your Gear Position Indicator AND program by gear.

But no, others have tried to break the 200mph barrier with stock Busas and came up short... That's not to say that it hasn't ever been done, or that it can't be done.
It is unlikely though.
If you try... a GPS is the only credible speed indicator device readily available.
Good Luck.... and Please Be Safe.
