My TTR has a proper speedo made by Yamaha. biggrin

I have another trail bike that didn't have a working speedo. An original fitting for it would be quite hard to find since it's a 1962 Triumph Tiger Cub.

In order that the bike would be legal on UK roads I've fitted a "digital computer" thing that's made for a pedal cycle. It is a wire-less version and works by a magnet fitted to a spoke and a reader fastened on the fork leg. The reader sends a radio signal to the speedo head fastened on the handlebars. confuse

The head records speed (mph or kph), trip distance, overall distance, highest speed attained, time from start, average speed.

Here's LINKY thingy

Here's a picture :-

If you want a proper Yamaha fitting then let's hope a NZ reader has one for you. smile

Martyn is right. A bicycle digital speedo is the cheapest option.

If you wanted an original Yamaha digital speedo then you need to check you still have the two connector blocks at the steering head plus the magnet and sender unit on the end of the sprocket output shaft.

If you have these then second-hand original Yamaha digital speedos are available - see http://www.totallyttrs.com/#Digital_Speedometer

Obviously cheaper if you can buy locally wink

A push bike speedo is only legal if it lights up when the lights are switched on.

Cubber · Super Guru

Not necessarily so, Truslack. confuse

Depends whether it's for MoT passing or to be within UK law.

A speedometer is not necessary for a UK MoT certificate. My Cub didn't have one at its first MoT, no lights either and only a bulb horn.

The UK law says that a speedo must be visible at all times - no mention of self illumination!

It's a moot point, but my Cub doesn't have any lights so the fact that I can't see the speedo lit up at night is no bother - it's never out at night or in bad visibility.
The bike is still legal to ride on the roads - and especially the local lanes.

New Zealand laws may be different, however. biggrin
