    Has anyone installed a tach on their X-Challenge?

    I have a TrailTech Vapor on my XR400 - love it... but I don't want to replace the display on the X-Ch, I just want to add a simple digital tach so I have a better feel for the engine speed (especially when I am wearing my ear plugs).

    Any ideas?

    I would like to get a tach on it too.. just to see what RPM I'm riding at, not essential but nice to know..

    I had a bmw boxer that did not come with a tach, and I had one added.. The F650GS has a tach and the X's engine is essentially the same, so a small digital tach should be do-able..

    Interested in links and mod possibilities.. :ear

    Should be real easy.... the TrailTech computer only needed one wire wrapped around the spark-plug lead, and another attached to the frame for reference ground. There must be something out there that is simply a tach rather than a whole computer like the TrailTech.

    I always ride the wave of torque.

    The only bike I needed a tachometer on was on an Aprilia RSV250 2 stroker. That engine pulled like a rocket from 8800 till 11999rpm, and completely died at 12000, so I knew when to shift.

    I also ride the torque wave on my GS, I don't use the tach to shift, I just ride by feel, but I like to have it to see what RPM the bike runs at when doing 100 or 60 or whatever..

    I remember seeing a flat LCD add on tach.. it was quite compact, any one has any leads?

    I found this in a Google search Tiny Tach

    Looks promising....

    I will email them to see if they have mounting instructions online for their tach to see if it can be fitted to the X.

    It's non illuminated, and it's disposable, when the battery runs out, you can't replace it..

    I found another one for Harley's, very small 2 digit LED tach, but it's a small add on for HD's.

    The battery lasts 5 years - the disposable part might not be an issue... but you're correct, it isn't illuminated.

    I emailed to see if they can send me a PDF with the mounting instructions to see how it will hook up to a thumper and the display adjusts for varying lighting conditions, plus you can program your redline so it warns you before you hit the rev limiter.

    Anything from TT costs a fortune, I'm not sure what the IMO goes for, but if the one I've linked above works, it would be great, looks like a quality piece too, and not cheap, but on par with what bike tachs usually go for, and it's quite compact.

    So far, I've not heard back from them. I emailed them to ask if it would work with a single cylinder enduro bike, if it's waterproof, to send me a PDF with installation instructions and what would shipping cost to this part of the world... waiting to hear back.. :ddog

    It's cheaper for us, it's 189 Euro plus 14 euro shipping.

    I heard back from the company, here's what he had to say:

    I don't know what kind of ignition this BMW has but often singles
    have a CDI which is not compatible. In this case you would need an
    additional ignition signal pickup unit (about 20 EUR).

    If you have an injection and a regular ignition coil no problem is
    expected.

    Or do you have plug caps with integrated coils?


    Any ideas Max?? :ear

    Hey: The TT IMO would work. I have one I removed from my LC4 but haven't installed it yet on my X. It connects to the CDI wire on the coil.

    What kind of ignition does the X have: :ear

    is it a Capacitor Discharge Ignition (CDI) that has a positive ignition
    signal to the coil.
    Or is it a regular transistorized ignition or EFI with a negativ
    ignition signal.


    We need to know if anyone wants to add a tach.

    its not cdi. most cdi bikes are carbed bikes. the ecu handles all the crap on efi. we do have twin plugs and i thought somebody somwhere on here tried hooking up a trailtech but it wouldnt act right cause of the twinspark. but i cant seem to find it.that being said. theres most likely a rpm wire off the ecu you can splice if you really really really want a tach
