Out of the 500 ideas this week I have had about my bike, this one keeps returning to me.

My bike is a long way from original, and in my hands will never return there, so this had me thinking about speedo and tacho units.

The GPS I carry round in my car gives an accurate speed indicator, apparently most of them do. And I have heard of electronic (as opposed to cable driven) tachos.


Now, I would be very surprised if someone hasn't married all this together as an after market dashboard setup for a motorbike. Ideally it would also have turn indicator lights and maybe the high/low beam indicator.


Anyone ever heard of, or even seen something like this?

You'd better patent this Dog or it will surely turn up on the 2011 Hinckley T100!! RR

No GPS here either,but.......

Nice thing about a Vapor is it is a true on-board computer. It will capture sufficient data to do actual dyno runs on the street to see if minor tweaks to things like timing or mixture make a difference and where.

I mentioned this in a previous thread on dyno runs. I have two friends who are much younger and race at Loudon in the LRRS. Both have Vapors on their bikes.

I stumbled upon the Vapors earlier, they are a very impressive setup.

I s'pose it was just laziness on my part that made me think of letting a GPS register my speed, as opposed to the traditional cable or an electronic setup. On top of having the other benefits of a GPS installed, it would mean I could eliminate one cable. Plus there would be a bonus of sorts if ever final drive ratios were experimented with, you would still retain a highly accurate speedo.

the vapor speedo is programmable . besides , it's sensor is reading off the front wheel/hub so change final gearing , tire size all you want . it won't effect the accuracy one bit .

the other thing is that there's a reason motorcycle specific gps units cost so much ($600 and up). they're built to withstand the beating of being cycle mounted . i've read many a post of car gps units failing after little use on a bike .

the cylinder head temp sensor looks interesting too .

cheers , Woody

Wow, I want one of those vapor units, dang it! I wonder if there is a sensor out there that could run off the mechanical tach drive so you could also use the tach feature of the vapor. Even if not, I still think I might have to have one.
crap there goes another hundred dollars!

no need for a mechanical tach drive . it's inductive off the sparkplug wire ! easy as pie .

main reason i'm going this route is my bike isn't stock anyway . originally didn't have a tach and my speedo while rebuildable needs a new drive and cable . add up all the parts for even repros and it's over $500 .

cheers , Woody

I forgot all about that it could be inductive! I guess I really am an engineer!

I wan't one mainly because I like gadgets, and my speedo doesn't work. My tach works, but once again, I like fancy stuff. I ride my bike, and while it still retains the stock look it will never be original. It's original to me, though.

Yep, It's official, I am gonna get one!
