Road legal KDX 200

I have now ordered all the lights and switches 'hopefully' from Ali Express. Still need to find a Bicycle computer or Speedometer. It seems Bicycle computers often only go up to 99km/h....

These go to 199. http://www.bikebarn.co.nz/echowell-u...-computer.html

Unfortunately no back light. I have found this: https://www.aliexpress.com/item/Univ...08.0.44.yidYti

How would I get it to receive the speed from the front wheel?

That's a cable operated speedo. Not obvious at first glance how you would calibrate it to the wheel size, if you have a speedo drive on the hub.

The bike speedos are connected via a wee magnet on the wheel. My Gasgas has the same set up, taking speed from the rear wheel. Trail Tech may be the brand and it's a good bit of kit. More functions than you shake a stick at, and a backlight.

I just had a look at their website. Blingtastic! http://www.trailtech.net/

From what I can see I think there is a speedo drive on the front wheel. Question is are all the cables the same? I suspect not.

Length would be the biggest issue IMHO. An easy fix.

Put something similar on a DRZ400M recently - worked a treat and looked better than the stock unit.
Went thru an australian EBay site - cost was around the $200 mark. Just an idea...

Thanks, I ended up ordering a $10 bike speedo, as if it doesn't work I have only lost $10. Apparently speedo's don't have to read above 100, so ti should be all good.

I didn't want to risk getting the wrong cable for the speedo.

What would you do for gearing? I tested it and the bike can do roughly 110, but that is of course going flat out, would it be a good idea to go up a tooth or two on the front?

[tlronny]

I would say definately yes to at least 1 tooth prob 2...

I got a decibal meter on my phone and measured the exhaust noise whilst it drove past, it measured at about 90 dB which is just within the limit thankfully. That gives me one less thing to do.

Update:

All the bits have arrived, finally, except the large capacity battery...

I have started fitting the bits on anyhow, I'm going to need ot make a bracket for the bike speedo to get it closer to the wheel.

The Headlight unit went on nicely, but the indicators were white!, I will get some more LED indicators to attach to the forks. Bonus is I now have some low power daytime running lights.
Mirror went well attached to the brake pin, but can't put one on the other side, so will live with 1 mirror.
Taillight will need some clever use of metal pipe to attach to the back securely, rear indicators will then attach to the taillight.
Hydraulic brake switch won't fit, so will fashion something similar to what the Jawa has on the rear brake.
Managed to fit the light switch unit on the handlebar on one side, but the e start, kill switch and lights on / off unit won't fit on the other side, not bothered about this as bike doesn't have an e start anyhow, and will make a simpler switch for the headlight on / off.

I forgot to order an indicator relay! So will probably make one.
Also forgot to order a front brake switch, so will try and source one locally.

So far I'm feeling confident, but have yet to do the hard bit, all the wiring.

Based off advice from onearmedbandit, I am planning on putting the magnet in the front disk for the bicycle speedometer, would heat be a problem here? I was thinking of glueing it in with a silicon based glue so it can handle higher temperatures without losing strength.
