That 112 mph cap means the bike isn't allowed to exceed 5K in sixth gear. We can see that in the video. Nonetheless, I know the bike does have a rev limiter that kicks in at 6K in the top two gears, which is a moot point in sixth gear, as the speed limiter has already kicked in by then. I'm not sure whether that would also be the case for fifth gear.
I just don't know whether the 6K rev limiter also applies to fourth gear. I thought I'd read that the top three gears are limited to 6K, but I might be mistaken. I do know that I'd want to be able to take fourth gear to redline.
I get what Ulvetanna and others are saying about there being no need to remove the limiters on this bike, since neither the bike nor rider would be particularly happy at 120+mph. Nonetheless, I'd still rather make those decisions myself, especially where fourth and fifth gears are concerned. I would hate it if I was in fourth and accelerating, having a good ol' time, and suddenly the thing just ran into an invisible wall at 6K. That would not be fun.
Hold on a minute. 4th-5th limited to 6K RPMs? I can absolutely confirm that is NOT true. I have run my CB up past that point multiple times.
On the subject of accelerating in 5th-6th gear on the highway, I have no issues passing traffic when in 5th and rolling on the throttle. 6th gear is a cruising gear, widely spaced and should really be used +70MPH. See below:
