as I've gone past 7k RPM in the lower gears.
Are you saying it will not pull past 7000rpm in top gear?
If so the bike may have stock gearing and almost NO Ducati will pull redline in top gear with stock gearing, that should not feel like hitting a limiter though.
will it pull to the rev limiter in the gear below top gear? I assume you have a 5 speed gearbox. is that true?
