I went on a 90-mile ride today and I noticed something I did a few times and wondered about it before. What is a good speed and/or rpm to go from 4th to 5th gear. I caught myself a few times coming out of the twisties that I would be at an easy cruise of 50mph and about 4800 on the tach then notice i was still in 4th gear. Should you always try to get on in to 5th gear or whats to high a rev for 4th and conversely whats too low for being in 5th

ps.. i did get to 100mph on one straight but don't tell anybody

the more i ride this bike the less i want to trade up

Well, I have noticed that this bike isn't to picky about 5th gear. Mine likes it just as well at 40 as it does at 75.

If if not on a very hilly terrain I will be in 5th gear once i reach about 3,500rpm in fourth, then i shift, I'd say dont go below 3,000 in fifth because it tends to "lug" lower than that if you really give it some throttle.

The idea is to shift to the highest gear when you are at cruising speed because that saves you fuel and over time engine wear. However if you need to slow down then you downshift to 4th or 3rd, or lower, as necessary to maintain good control speed and keep the engine in a good power range. When you return to a steady cruise you shift up and eventually get back to 5th gear. I like to downshift when decelerating because it help my braking and give me power when I need it to speed up. I also downshift when entering a curve so I can power my way out of the turn.

Many of us have been looking for 6th gear when cruising at 60 or higher but unfortunately we don't have one.

You know, I never really paid attention to this. Basically you can ride in fourth up to redline, but seeing as there is a fifth gear :) you should shift into it around 5500 or sooner.... Unless you're passing a truck or something. Answer there is there is no set answer as it depends on the circumstance and....if you are trying to save fuel.

At the other end, V Twins make good torque at low engine speeds, so you can go 40 mph in 5th. I personally wouldn't go below 2500 rpms in 5th, but again it matters on the terrain,wind speed, and how well the bike pulls at lower rpms. Going up hill would be diffrent than going down hill.

After awhile you should be able to know what gear you are in by looking at your speed and just listening to the motor.

As a good rule of thumb, if you grab a bunch of throttle and nothing seems to happen faster, you need to downshift.;)

The Vulcan 750 is not your typical long stroke v-twin, and is designed more for top end power than low speed torque. On a fairly level road, I won't go below 40 mph in 5th, and if it looks like I may be stuck at that speed for a while, I will usually downshift. Climbing a hill, you need to downshift even more to keep the rpms up, as you are putting a lot more of a load on it. When climbing significant grades (yes, we have those here on AZ), I try to keep the rpm at at least 4000, and use whatever gear is necessary to do that. If you let it drop much below that you are falling out of the powerband, and lugging the engine.

If I take off from a stop on a rural road, or turn onto a freeway on ramp, I usually shift from first to second at around 3000 rpm, then shift through the rest of the gears at 5000 rpm at full throttle, until I have gotten just a bit above the speed limit.

Though it is supposed to go faster, the best I have been able to get out of mine, tucked in, is an indicated 110-112. That's an actual 105. I have heard they will do 120, but mine won't.
