Legality of a home built speedo/odo

[FlyingDutchMan]

Not sure if the regs are the still the same, but a friend of mine used to do WOF stuff & he was going to fail some vehicle for not having a speedo & the guy argued that it had a tacho & he knew how fast he was going from that. So he called ‘the man’ & was told the vehicle required an instrument for determining the speed of the vehicle’. Pass.

I’d love to put a digital speedo on my YZF, but too much like hard work & I have far more pressing projects.

Thats what I had been using for quite a while until I got the digital one going. Seems by that rule that you can use a wind speed measurer to detrime your speed .

I have a wrist watch & I'm pretty sure that lamposts are a std distance apart. Let's see 10 in 18 seconds @ 40.3M, um, carry the 4, now did I include the 1st lampost into the ten, in which case it was only nine lengths.

Yeah officer I think I was doing 50. (or 212, or 7-1/2kph)

Well its legal enough for the WOF man to give the bike a WOF.

I used to have a cycle speedo on my XT, dick smith $20. on my 1st attempt I was told no cos it wasn't lit. so I went to the petrol station next door, purchaced a torch, got the ducktape out of my toolbox, taped the torch on to the bars (direction of the speedo)
And well, Bobs your aunty it passed. Oh and the guy doing the inspection nearly wet himself...

After that I did wire in the most pathetic light off the headlight which took it through a few more wof's.

The WOF form on their computer does require you enter the total distance travelled for the bike. This must be more than the last warrent. So maybe a bit of tape and a marker pen ....

My guess anything is possible ....

for info on selecting a computer...

Just read bike trader about molestrangler discovering Ram air induction, by farting on the carby... Maybe you could make a gadget that would count the farts... Or put a piece of sticky tape there to actually catch a real live one!! Hah...
Sounds like some good indigenuity out there!! Go the duct tape way of life I say!!

odo is not compulsory.

So for certain it is not necessary to have an odo on a road-legal bike?

Get a rope, tie knots at regular spacings, throw it out the back......

When I was restoring my bike my speedo was in a place being reebuilt, the one man band operator had a serious stroke, my bike was ready to put on road ... and no speedo
I had debates with my wof supplier who said no speedo no wof, I spoke in length to LTSA and they agreed the law states you must have "a device to indicate road speed" I told them that at 2500 RPM in top im doing 50km/h, at 3000 im doing 70, at 4000 im doing 100km/h ... whats the problem ???? they conferred that yes thats acceptable LOL ... so got the wof.

Speedo finally got reassembled and back in bike .... reads wrong tho so hased to come out again and this time sending it to Hastings to be calibrated.... its reading about 20km/h slow at 100km/h

I think the law is basically ... as usual ... open to interpretation lol
