Speedo Error

[nzspokes]

Ditto ^ for the reason below cause I'm a Dutchie...



But yep, like Rastus mentioned, most speedos are optimistic. So when you get pulled over for 110, your speedo would have been 5 or 10 above that again...

My bikes are re-geared so stock setting is a mile off.

Bike reads high by almost 8%.

I mentioned this to people at work a while ago... quite a few colleagues said they'd correct for it (they're technical people) but get told off by their other half (believes the speedo reading at face value).

15% would explain a lot of the crawlers on the motorway.

My Ducati read 30kph slow - Italian electrics? I'm still grateful I found that out before the HP informed me. That prompted the purchase of my first GPS.

[OddDuck]

I wouldn't know about electric speedos, mine is a dinosaur mechanical cable off the front hub! Whatever works I guess.

The smartphone speedometer app has a GPS in it but without testing I couldn't rate accuracy.

My Aprillia was a bit optimistic....

The Harley was shaking to much to do anything other then guessing.

BMW is pretty close to the truth.

Honda is gay...and correct within few k's at a hundred.

All my European cages are also boringly accurate....

All this explains why I end up overtaking lots. Cars drifting along at 95, thinking they are doing 104.

When I used to write the odd speeding ticket I had a lot of people saying that they were just keeping up with everyone else. When in fact most traffic is at the limit at best.

The 1150GS I had read 109 at a true 100. Despite what EJ thinks, the Chermans weren't always so precise.

My Ducati book tells me the speedo is set 8% high by the factory. So I ride everywhere at 110

The new knowledge actually makes us go faster.

it means there are two people on the road,one guy in my vw van at 100 km's hour with my gps and the next guy using his speedo doing 89, and each other thinks the other one is bad for either going too fast or too slow

the checking of speedos to be within 10% accuracy was removed when the cops issued tickets for 4km's over (4% at 100km's hr) as imagine standing up in court and syaing the government accuracy is 10% !!!!!!!all that means is no-one is checking any speedos really now except maybe that they move off the post

[jellywrestler]

That's why I love Germans. Their speedos are only -2% whilst other Japanese cars/ bikes can vary somewhere around 8-15%

98kph actual at indicated 100kph last time I checked. They don't joke around.

my vw van is 11% either or how can they be 2% the tyre tread accounts for more than that?

Not sure about VW and vans. Never driven one. My experience is based on my ol S1000RR and driving Audis, BMWs and Mercedes down to Queenstown and back.

You are also over paying your diesel tax by 11%

Good point. Wonder how much a hubbo costs?

[jellywrestler]

fuck, never gave that a thought, and the oil changes are more regular and the mileage that it's covered greater....

Not quite as bad as my Gilera but confirms my theory.

[russd7]

the goldwing is pretty much bang on, the zzr at 120km/hr indicated had me pulled up north of lumsden doing 111km/hr, nice fella that guy just got warned to slow down as the QT highway guys were out an about as was confirmed by a text message from one of them askin if that was me have a conversation with the local .

the hyundai indicates around 6km high and the mazda/ford van is spot on and still got me a ticket for 118km/hr running on three cylinders
