Installing A Speedometer

[MitchAustralia]

Hey guys,

Wondering if it is possible to install a speedometer into a pit bike.
I have a PitPro 140 XR by the way.
All I want is something shows the speed and maybe the RPM.
Im doubting it is possible though.
Anyone got answers?

Thanks, Mitch.

what about a pushy speedo.
the ones u get and set up for the wheel diameter,prolly wouldnt be 100% accurate but might give u and indication of how far over the cops book you....if u stop lol jk.
not sure about the rpms though.

 

[MitchAustralia]

ok,
so your saying that there wouldnt be speedometers out there with the wheel diameters I have?
couldnt you adjust that if it was a computer one with like a LCD screen?

 

[r1inoz]

im saying that u could use one of the push bike ones as u set them to yr wheel diameter.
work the same on a 10 inch or 21 inch i would imagine

you could have a look at the trail tech vapor things on ebay, i have been told that they are ok. just make sure that it will fit.

 

[MitchAustralia]

I never new some bikes has speedometers. Haha
Pedro, yeh I saw them.
Im trying to imagine how it would fit though.

Does everything rely on the wheels diameter?

pretty much, some use worm gears and take the speed from the gearbox.. RPM will be taken from the coil..

supposably the charge from the motor interacts with pushy speedos and makes it say your going heaps faster than you actually are

 

[MitchAustralia]

Hmm,
anyone got suggestions of ones that would fit my bike?
I had a look at the trail tech vapor and the cateye one?
I have no clue?

i guess if you had the wires of the speedo close to the CDI or the ignition system then that could cause some interfearence. I dunno.. I rarely looked at the speedo.. was more there for afterthought and to see aprox how many total K were covered .

there would be something available, the Z50 used a worm gear on the hub and is cable operated.. if being slightly inaccurate bothered you that much, im sure you could have a similar adaptor made for some serious $.. not worth doing IMO..

yeh, those monkeys look like fun to ride on the road
what bike do you have?
did you install the speedo yourself or did it come with it?

 

[foolsp33d]

that speedo was on an atomik 125.. long gone..
yeh I put it on..

Currently have a PP110, z50 w/125, xr250 roller.

dunno if id be to keen on riding a monkey on the road.. full size bikes are in enough accidents..

got 12 inch rims? why not contact motovert and get the speedo unit off of an rx50/125? all youd have to do is mount a magnet to the hub
