Just installed this on the bike..
The Ultimate Gear Indicator with built-in Advanced Timing Retard Eliminator
Not only does it display acurately what gear your in but it has a built in advanced TRE.
what does that mean?
for the Hayabusa it Improves throttle response and acceleration in gears 1 through 4.
Gives smoother part-throttle response in lower gears.
Bypasses the top speed restriction on GSX-R1000, GSX1300R (2001+), M109R and DL1000 models.
So this should be interesting to see what it can do.
