WASSAP

My Suzuki is a grey import bike, thus is not a UK standard market bike. The clocks are in KPH and I wish to take the test using this bike.

However, as the law stands, I need to have a MPH dial on there, too. So, would it be possible if I just put stickers along the outer casing of the dial to show how fast I am going in MPH to meet the test standards?

Thanks for any advice

Make your own using card, pritt stick and a printer - easy enough. It's not something they'll pay a lot of attention to - you'd probably get away with the km speedo unless the examiner knows a lot about bikes, is really observant or you're unlucky.

Mine Passed its test with KPH dials, But then again I have a converter attached to the back which is visible to the tester.

WOAH WOAH hang on....

I have that already, I thought it was just an extension!

So, I don't need to do anything else? The dials are still in KM per hour, this is what I have bought (Had to buy new speedo, previous owner is a twat...)

With this, I do not need to do anything to the dials? The needle reaching 40 will mean 40 MPH and not KM p/h?

Why not test it out?
With GPS if you have it, or if not, ride on residential roads at 30 indicated and watch traffic. You'll soon know if you're going too slow, 30km/h is 18mph.

Or go for a top speed run, if you get over 70km/h then you know it's not in mph.

Fit the converter, mine is an import and although I haven't had to take a test it passed the MOT fine.

It will be reading in MPH from then on, so yes 40KMH on your dial will be actually 40 MPH.

I kept a note when mine was fitted ie at about 35000 km because the odometer will go up in miles from then on as well, I now have 51000 showing which is 35000 km plus 16000 miles total!

Do you really need a clock with MPH scale or just know how fast you go? Here in czech rep you don't even have duty to have a speedometer. I've got UK import bike here, MPH scale clock and no one cares at all. I think it's even impossible to convert mph clock to kph since my mph clock ends with 115mph and the bike exceeds 190kph.

Of course it's possible - the speedo needle moves in relation to engine speed. Which means you just need a new printout for the dial.

I would suggest if you can't tell the difference between 40kph and 40mph you might have some issues on the test.

which test are you talking about? for an mot it doesn't matter what they display, for your mod 1 and mod 2 tests they have to display mph and the stick on overlays you can buy are not acceptable

Ride past a 30mph speed camera at 40. If it goes off, your doing MPH not KPH Thumbs Up

No it does not! It moves in relation to the gearbox output shaft or the rear wheel. Tacho moves in relation to engine.

Exactly, the mechanism takes final drive speed or speed of the front/rear wheel. Rev counter counts ignition impulses or exact speed of some moving part of the engine via cable, mostly the exact speed of camshaft.

And I don't think that it could work, If I get it right, this feature changes your KPH speed into MPH speed, so if my speedo ends with 115MPH, then it would mean that the needle would do 2nd round around the scale to get 190kph.

Quite, the gearbox output was what I was inferring, do any bikes in recent times still do the rear wheel?

I was simplifying for the benefit of a discussion with someone who may/may not know the difference between 40kmh/40mph - I think I simplified to the point of incorrectness Doh!

Hi

Not certain but from memory thomp1983 is correct and the overlays are not meant to be acceptable for doing your bike test.

As an aside, technically in the UK the speedo must show both MPH and KMH (or can be switched between them) but this is not checked in the MOT or anything like that. You can get mechanical converters to gear down the speedo cable hence the speedo reads in mph rather than kmh, and as the speed in mph is a lower number than in kmh this works fine. Technically speaking not strictly speaking legal though (as it no longer shows kmh), but not something most people care about.

All the best

I hate bikes...

I have the extension mentioned before. I've had to order a new speedo cable as the previous one seized, so I won't be able to try it out until later this week (and to ride illegally!).

What I'm trying to ask (BTW my bike cannot do more than 110 kmph) if I install the converter, will the needle point to, let's say, 40, to mean 40 MPH and not Kmp/h?

If you have the blue connector on the back, Your bike will be reading in MPH.

Just point it out to the examiner.

Right OK I have an update

My speedo cable arrived today. BUT, I have a problem. When the dial reaches 30, it does not seem I am going 30 at all, it feels like I'm going 20. Plus, when I get the speedo up to 60, it feels like I'm going 40. Now the funny thing is that my bike cannot do more than 45 because I have a cracked inlet manifold (due to be replaced), so I'm left wondering how the hell that's possible.

I did an experiment with the trip meter. I set a route for exactly 0.7 miles. I did about 0.6 miles in that route and the trip meter showed 0.6. If that was KM it would show around 1.1 km, which tells me both the clocks and the trip meter are functioning in miles per hour.

Has anybody got any suggestions why this is happening? I'm using that converter at the moment
