    Aftermarket Speedometer? Anyone?

    Does anybody know if my 82 gs650's speedo cable will fit into an aftermarket speedo? And if I get a wrong speedo, will it read wrong? How should I go about this? Any insight will be greatly appreciated, thanks guys!

    IMO, it's far easier to remove the mechanical speedo drive and install an electronic unit.

        What needs to be done to accomplish this conversion?

          easy to replace. make sure you get a speedo with a ratio of 2240:60 so it reads correctly.

          you also need to make sure it takes your squared speedo cable end.

          this is the one i purchased, works great.


          there are others online if you search "2240:60 speedometer."

              The electronic ones have you mount a magnet on the rotor carrier or wheel and a sensor on the fork leg. They work the same as bicycle speedos, counting revolutions with a measured wheel circumference.

              Since growler posted a link showing some that will work with your drive, that is even easier. I never expected to find any mechanical drive aftermarket speedos anymore.

                GPS speedo there are no cables, no ratios nothing, just a 12v supply. Can't get much simplier then that. They supply you with a GPS antenna.

                  That kit is set-up specifically to work on old air cooled bikes like ours, and that's per one of Trailtech's own advisers. It's the kit I will be getting as soon as I get some disposable income again.

                    According to the wiring diagram, the yellow & yellow/black wires go to your winker. Let me know how that works out. Also may pick this one up.

                      Thanks for all the input! Are all GS bikes a 2240:60 ratio? I see you (Growler) have a GS850, just wondering if since your bike has a bigger engine, 60mph could be achieved at a lower rpm? I mean, if it's accurate for you, it'd have to at least be in the same ball park for my bike. I'll try to do some more digging!

                        That ratio is correct for most if not all Japanese bikes.

                          I wired exactly as the instructions stated. No issues.

                            So, no problems with your winker, then?

                            I gotta say, DCC's sales pitch is beyond compare:

                            "In a world of "man" envy saturated with fat tires and big engines which supposedly directly correlate to well, you know.. Be the bigger man and roll with one of these 2.5" mini speedos. You ain't got no shame and no reason to act like you do. You're a mans man. A big man. A real man...

                            You ride a teeth shattering hand built Cafe Racer or a hard-tailed hunkered down Bobber and that, speaks volumes. Chances are if your piloting one of these jockey rockets down the road you've got balls of steel the size of Texas. Covered with a generous portion of black powder coat and only available at Dime City along with anti-vibe construction these little suckers keep your speed and, women in line just begging to be wrung out. And, at just 2-1/8" tall you can fit it just about anywhere"
                            Current:
                            Z1300A5 Locomotive (swapped my Intruder for it), GS450 Cafe Project (might never finish it....), XT500 Commuter (I know - it's a Yamaha :eek:)

                            Past:
                            VL1500 Intruder (swapped for Z1300), ZX9R Streetfighter (lets face it - too fast....), 1984 GSX750EF, 1984 GSX1100EF (AKA GS1150)
                            And a bunch of other crap Yamahas....

                              I may have to check these out. Been looking at replacing my whole cluster area with a more updated look anyways. Is this a direct bolt on from Dimecity as in no mods needed and cable lines right up? any pics on your rides?
