How could you ever think about going 125? I havent been over 80! Just the thought of me trying to put loose skin back on in pain while my gf is screaming at me makes me not want to do that.

First off I would not suggest making top speed runs with your girl freind behind you..or anyone else for that matter.

Again I need to point out that speed is relative and how one reacts to it subjective.

I can honestly believe that those who now consider themselves to be "old farts" have just got to a point in their life where , to be perfectly blunt...are just afraid ..........of death (or pain) so much more than they were when young that they can not fathom going 3 digit speeds.
Some like me and Old Dog likely feel that life is short and anything that makes you feel more alive or gives you a thrill is a good thing. We don't let fear rule us, we actualy see it as a challange.

But those that now say they have no desire to go over 80 mph now , may not be telling the truth when they say they "never would go that fast" when several admited that "when they were young and foolish" they did exactly that.
I think it is basic human nature to explore the bounderies one has access to, and when someone says they "never" have done something most times they mean " I no longer would do that". I think when we all were young we did ..and it was not because we were foolish, but because we had less fear and a stronger sence of curiostity.

I also have to point out that many "old farts" are new to riding and if you have not grown up with motorcycles you will have a different perspective to start with.
When I first rode my very first motorcycle, I remember quite clearly how terrified I felt just going 40 mph for the first time. Without the cage of metal around you and being able too see the ground under your feet whiz by tends to make anyone feel a bit apprehensive, even at sub light speeds.

I do have to point out to Marine and others that being that unprotected as one is on a bike, that once you reach a certain speed, you can't really believe you are any safer than if you were going faster. To this I mean if you mess up or get nailed on the highway going 70-80 mph, you will die just as quickly if you were going 100. To be quite honest here, if you hit a road sign at 45 mph your chance of survival is pretty much the same as hitting it at 120. (that is if you hit it head first)

I should also point out that most accidents occour at speeds under 40 mph, and that when one is going "fast" they tend to be completely focused on their riding...which tends to make them safer riders...not the opposite.

Next of course you have to trust your machine. Odd and weird things can begin to happen as you approach the century mark. Imperfections in the suspension will be exaggerated, and of course your aerodynamics can cause all sorts of problems. "Cruiser" style bikes were designed to, well, cruise , not break land speed records. Even if the engine has the potential power to go 120, that does not mean the bike itself is up to the task. If you have any concerns about the reliability of your scooter you are wise not to push it....or at least get gain some understanding as this would just be something to add to the "fear factor" one might have going exceedingly fast.

The fastet I have ever been on the street was about 136 mph, and that is on the FJR not the Vulcan. Fastest on the Vulcan was an indicated 120..but was clocked at 111 on radar.
But I have likely gone faster on a track. Back int he late seventies I got to take a TZ750 race bike around the track for a few laps. I never count this only because the bike did not have a speedometer, and I have no real idea how fast I got on it...I was fairly petrified the entire time. I do know that the run down the 1/3 of a mile straightaway seemed to take about 2 seconds...or at least twice as soon as my bike.

I know Kenny Roberts TZ routinely hit 189 on the staights..but this was not a TZ with gobbs of money thrown at it, but a "Stock" unit. Still , it was fast.

The Point here again is if you spent part of your life on a bike going over 100 mph on a fairly routine basis, you tend to have a completely different perspective than some "old fart" that is totaly new to motorcycles that tends to like "cruisers" and has some real fears about their abiltiy to heal broken bones at their age.


I don't mind if you go slow, just don't call me "crazy" cause I don't, and do me a favor when we meet up on the road, wave and smile back , but get out of my way.

The highest my "gps" said was about 110 and she was screaming at that. 125/27mph on a VN? Not sure I'm buying it. I think certainly these bikes could do it and maybe even a little more with a 6th gear. I think realistically 115 is probably the most you're gonna get out of it without major parts flying' out from between your legs cuz you're gonna be into the red zone. Even 110 is very impressive for these little 750's especially since they're not outfitted with sport bike fairings and aren't aerodynamic at all.

I don't doubt the bike can go 125. And I mean actual, not what the speedo says. Much more than that...No.
I'll take your word for it KM, I'm not crazy enough to try it. But did push just over 100 and that was riding two up, or so my Tom-Tom said one day. Didn't stay there long, just want to see if it would do it.

Thats crap. I did 130 on my 1989 Vn750 back in 95. I still had throttle just ran out of testosterone.
lol yeah ok. unless you modified the gear ratio I aint believing it, especially "still having throttle". Thanks for the entertainment tho.:smiley_th

I should point out for those that Don't Get It....the speedometer is about 10% off. So if it says you're going 130 mph.... You are in fact only going 117 mph.

The only way the Vulcan can do an honest 130mph, for those seeking death and destruction, is downhill with a stiff backwind and the tach pegged past the redline. Considering how light the front gets at 110 mph, you'd be an idiot to try.

Not entirely true, KM, depends on your front tire size. Mine is only about 1 mph off at 60mph indicated. My GPS's says 59, used two different GPS to check the speed. Now this is with a MT-66 up front. With the Brigdestone S-11 it was reading 3 mph faster that the GPS, or about 5% off. Again that was at 60, and at 130 it would be off a bit more I think. With the front tire, size matters.

maybe...but what if I installed a fin to force the front end down like on Indy cars....lol

Yeah the bigger tire will help with speedo accuracy but the engine's most likely comin apart in short order pushing it over 110. Plus I agree with KM and found mine to be skittish at and over 100. Stock front tire but I don't think the bigger size would have helped much. My small windshield may have added to the behavior but not that much. Again, aerodynamically it isn't set up for doing that a lot, fun as it is. I'm happy the little pumper can hold 80-90 long term. I'd never want to run louder pipes on it though because of frequent highway travel and the high revs.

A properly tuned VN 750 will give you all the speed and then some that you need for normal travel and for those that are beyond normal it will do some of that also. Believe it or not I have had mine over the 85 mark also even if some that have been on rides with me doubt the statement. I am glad I do not need that extra top end but what the heck, I still want a 106 ci, 6 speed Victory. I guess it is like when you go out. You don't need to be with the hottest looking woman in the place but why the heck not go for it anyway. Hot bikes and hot women are similar in that there are times when you just have to hang on and go along for the ride.

Sadly the odds of you getting killed going 45 mph are way better than if you're going 100. And quite a few riders are killed each year when their bike is actually stopped.



But, should never go faster than you're comfortable with.....

I'm just happy that the VN can haul my bulk at a comfortable speed and still have enough in reserve to tap if necessary.

I just ride to enjoy a ride at a leisurely pace.

It'll be there when I get there. If it's not, there's nothing I can do about it anyway.

Now, if i could just get all these other people off my road so that they're not trying to run me over I'd be set.

Lots of teenagers out this way in daddy's unnecessarily gigantic pickups that haven't yet grasped just how quickly the illusion of control can disappear.

too true.. while no fatalities where incurred, I know someone who rear ended another rider (they where in group) when they came to a stop at a light. A little investigation showed the rider who was behind actually had a piece of metal (alum siding scrap perhaps, it wasn't big) get under the front tire while under braking... it stayed under tire while the metal began to slide along the road... instant lack of stopping power.

Now, had the rear rider been using both front and rear brakes, the incident could have been avoided, or at least the severity reduced.

This is a lot of interest in a thread with an OP that is seven years old.

I have mentioned in several threads over the years that mathematically the gear ratios give the vn750 a speed of 14.52 mph for every 1k rpm.
8.5 k rpm redline equals approx. 123 mph theoretical possible top speed.

Link to equation to calculate gear speeds. Motorcycle Safety Site
I do not have my manual handy to give you the gear ratios right now, but you can look them up.

Two summers ago I changed out my OEM size 100/90-19 front tire for a 110/90-19, which theoretically brings the speedo reading almost to the true speed traveled.

Riding on a newly repaved beautifully smooth 2 lane highway with virtually no traffic, I had my 750 up to a ton or a little more indicated speed on a windless day. At the time I weighed about 300 lb and had no windshield on the scoot. I had the throttle twisted to the stop for a few miles to get there and was slowly picking up speed as I continued. With a small windshield on I may have held her wide open for a couple of more minutes, but it was getting to be a bit of a struggle holding on.

I have a big windshield on now and have lost 45 pounds or so. I may try for my personal best top speed again next summer with a new tire on the rear too.

So the time I had mine up to 9500 in fifth would equal 137mph?YIKES.on a Swiss cheese rotted out frame with bad front wheel bearings?either somebody likes me or he ain't ready to see me yet.glad I switched out the frame;)

9500 in fifth? Couldn't get 8200-8300 in fifth before i made the engine bigger,maybe on a big, very big downhill would go 8600rpm.
