so there was a thread of some dude doing a speedo change on his 02 sporty , didnt wanna hijack the thread but I had the idea whats the smallest speedo you know of, was thinking to make a suicide shifter and mount the speedo on top inside an 8ball or something, have the shaft of the shifter made out of 3/8 tubing or smaller and run the wire down the tube out to the wires on the bike.

chop the 8 ball in half hollow it out hinge it so you can pop it open when need be that way you have a sick set up and dont have to worry about a ticket

Since i dont have th facilities to make it and or tools it would be cool to see someone make that come true PM me if your down id just like to see it

Mounted on the front brake master cyl. Ran the pick up to the rear wheel.

One of the latest chop cult specials/photo's profiled a bike with a garmin GPS (size of a watch) for a speedo. I run a dakota digital by my oil bag to keep me street legal. Wish I would have thought of the garmin.

This is going to sound extra geeky but it works with today's smart phones, rig up a mount for your favorite flavor smart phone and run a GPS ap. Personally I like the bike computer ideas best and I loath the digital modern stuff and I think the smallest ones I've seen that are analog were about 1 1/2" which still isn't that small.

1 7/8" is the smallest common analog speedometer size, but every once in a while you'll find an oddball that's smaller. I've run a Motogadget motoscope tiny, which is really nice because it's super-shallow and has an analog and digital display plus idiot lights, but it is stupid-expensive, and the $40 sensors are really fragile. Unless you're stuck on the 8-ball design, I'd just run a gauge cup as a shifter knob, throw a gauge in it, and call it cool.

Just FYI, in addition to a speedometer, some states require a non-resettable odometer, which most GPS units don't have. Sounds obscure, but I had a cop check it at a stop once, and I know people who have gotten tickets for it. Definitely worth looking into where you live if you plan on running a small speedometer or a GPS.

Any clue what the small garmin is called?

image searching watch gps brings back loads of them, to choose from not just garmin.

I like the hinged 8 ball idea and it's totally doable. I run a bicycle speedo that would fit inside. The wire runs to the front fork and there's a magnet (rare earth) on the disc. You'd just need to make sure you can pop out the computer to change the battery. You also have to make sure the speedo will register higher speeds (a lot of them don't). Good luck and post some photos.

lol! Switch it to the 'flame' setting and just go hit some sweet jumps
Think of the missile that little unit would be when it let go at about 60mph!

Just got this in the mail. Need to set up a speed sensor with a magnet on the wheel. My bike has aluminum wheels, woops.

buy a small rare earth magnet and some epoxy from home despot, clean the surface before gluing and it will stay there for a few decades.

I hope it works out ok for you; I haven't tried one but was considering it for my current build, the round one on the same page in a link isn't all that large either.

Maybe if you could force it to stay at a certain speed as max; may we see the officers dash cam? 110? My wheel says 56 clearly seen in the video.

If fighting tickets is your thing though; asking when the last time, the speed monitoring equipment in the cruiser was calibrated will dismiss the case. It's expensive and requires a company tech to come do it, they can't do it themselves...so bear that in mind.

Sources: One of my 1st cousins is a Sheriff, he told me about calibrations. One of my moms friend's is a state trooper; his son gave me this "secret" advice for interstate; you're safe at 8 over in every state. Most all state troopers universally set theirs at 10 over, he said some of them set it at 9 just to be assholes, but anything less is highly frowned upon.

I've driven 8 over ever since, nearly 20 years cross country up and down the Eastern and Western seaboards passed by cops hundreds of times never broke cruise control from 8 over and have never been pulled, I got flashed once...it was only by the headlights though not the rack lights.

after you glue the magnet on, get some of this stuff for the inside of your tire to balance it. I have it in a couple of my bikes, but I dont put a lot of miles on them. My dad has had it in hos stratoliner for like 40,000 miles and it workes PERFECT! you dont need the special valvestem with the bigger beads and these ones all static cling together stick where they are needed even when you stop. plus... no more wheel weights.
