Agree with Freddy... bought a Schwinn unit at Wal-Mart for less than $20 (US) and used a rare earth magnet on the rim to trigger it... spot on against GPS... (my speedo indicates 62MPH at 55MPH actual).

Leonard - That IS a good one! I agree in principle with that cat - but SAFETY equipment is one thing I'll NOT do without. Yeah - I did the helmet protest in the late seventies by riding around with one on my leg (wearing it ...) - but again - it was the principle .... I don't think a fellow should be FORCED to wear a seat belt or a helmet if he doesn't want to .... BUT .... I think you give up the right to cheap insurance (like health insurance if you are a smoker) and some medical coverage if you choose to ignore the obvious. I always wore the helmet (on mah haid!) without the speedo .....  ;)

The only time I ever peak the speedo is when I see an officer - and that's just habit.  Otherwise on a Bullet, I'm not terribly concerned.  If I was sitting on something red and Italian, I might want some accurate data.

Red and Italian is a tried and true revenue generator for the local constabulary - ASK me how I know this ..... This is why it's anchored to the wall in the garage with cobwebs .... I finally KNOW better than to ride it without looking at the instruments. A "heads up" ride will usually yield the "ton" just as I'm going into fourth gear ......  ::) (and there are two more to go!) ;D

Talking of the speedo, is the smiths more accurate than stock. And is it plug and play, you know, take the stock off,plug the cable, twist the throttle kinda plug and play.

  To a certain point yes.  The stock cable on the classics (military/custom/deluxe) attaches no problem.  However you lose the neutral light/turn indicators/high beam indicator.  I have a different variant that has a green illumination ring around the outside that brightens the night display.  I also modified the bulb holder to put a larger bulb in for back lighting.   Had to do some engineering work on the hold down clamp also (drill/file work).

  And mine is within +/- 2 mph from accurate with police radar (had my neighbor the Deputy Sheriff gun me. :D ;D :D ;D.

I checked mine out with a tach and it's actually quite accurate from 40-75. Didn't go faster than that, but slower it's a bit off, and below 40, who cares.

The speed hypothesizer on my '09 AVL pretty consistently read right at 10% above actual speed (at least going by the maybe-not-any-more-trustworthy speedometers on my friends' Japanese bikes). The speed hypothesizer on my '01 is a different story - it seems pretty accurate, so long as I overlook the needle's constant swaying.

Japanese bikes have notoriously fast speedometers. They run about 10% off. So do Hinkley Triumphs.
I originally thought my speedo ran about 10% fast and rode the bike accordingly, but I kept wondering why I was outrunning most of the traffic I wouldn't have thought I would be. So I attached a tach and compared my speed to a RPM/MPH chart I have. the spedo and ttach were very close.
Have you ever lubed your speedo cable? That might get rid of the swaying needle. There are speedo cable lubes available at your local Auto Parts store. Or just white lithium grease works. Don't get carried away, a thin coat is plenty. Too much can get up into your speedo, not a good thing.

I've heard that the tire size may make a difference. Mine seems pretty close to true so I'm not concerned. If the 10% is true then all those boasting their mileage milestones are actually 10% off. 1000 miles is actually 900 miles etc. Not that it really matters I suppose.

Not necessarily true. The US law requires odometers to be accurate, Speedos not so much. If you're running stock tires it should be on. However, like you say, tire size changes will affect the accuracy
The odometer works off mechanical gearing. The speedo works off a magnetic gap. The gap can be changed to correct the reading.
However a 10% tire size change would be pretty significant, so in actuality the error with a normal tire change would be much. You would have to have an inch larger diameter tire to change the speedo by 10% from 27"

Like many posts on this subject, just keep your head up while cruising on your RE and forget about that GD speedo. It's really hard to speed on these things and you will get to know your approximate speed by knowing which gear you are in and just the sound of the engine. The wider the grin on your face is also an indicator of speed I find.

I agree with barenekd on this. I've had a V-Star 650, an FZ1, a Shadow Aero 1100, and a ZX-6R, and based on traffic during rush hour comparing it with my average passing/being passed rate in my car, I would estimate that an indicated 77mph on all of them equaled something very near 70mph actual. On the Bullet, it seems very close to 70=70. I plan to mount a GPS for traffic info someday (future farkel), so then I'll know for sure.

Not that I ever expect to actually speed on the Bullet, but I just have to know!

Agree with that.

I put a cycle speedo on by Bullet and found that my guesses had been pretty much spot on.

And now I know my cadence and how many calories I'm burning  ;D

I've been switching into fifth at around 43mph according to the speedo. Does that seem like too low of revs for fifth on these things. It seems fine to me and I don't go any slower than that in 5th. Just need some opinions out there.

Sounds good to me but, what do I know?

Actually that is about where I shift into 5th if I'm just putting along with traffic.

Accelerating to blend in with freeway traffic I usually shift into 5th at about 60 mph.

Well, I got up to an indicated 88 mph today. Now I'm suspicious of the accuracy! Considering the lane I was in and the relative speed of the traffic, I suspect I was doing closer to 80. Gonna have to mount a GPS to check it out.

I'd like to be able to check the top speed before and after I install my Slip Streamer wind screen.

Rather than a GPS, why don't you invest $5.00 on a stopwatch and go out on a highway and time yourself for a mile or two and see at that results in?
I'd use that method myself and I even have the watches, but good old Cantaffordia doesn't post mile markers because the asshole taggers love to paint them.
