Wee Speedometer Accuracy

Hi. I'm on the cusp of buying a 2011 DL650. Some of the threads here have me wondering if the speedometers on these bikes are very accurate.

Can anyone clarify, especially as to the later end of the 1st generation? My old Virago's mechanical speedo is spot-on, so I'm scratching my head that a significantly newer bike would have an inaccurate speedometer.

They read about 8% high. I replaced the speedo face with a corrected one that a forum member made years ago.

Generation doesn't matter much. Every one seems to be within 7-9% high. The odometer is more in the neighborhood of 2% high.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

I must say that I find this crazy, in a disbelieving sort of way. Not that I doubt anyone. It's more that I can't believe something this basic would be that off.

They seem to do it on purpose, and it seems to vary by market. No idea why.

Lots of talk about this on an Africa Twin forum. The US bikes are spot on. Exact speedo accuracy vs a GPS. Other markets, they read 6-10% high depending on where the bike was sold.

61 indicated = 55 on GPS on my 2013. Stock 15t to 16t will help if you want to relax engine during cruise and are willing to give up a little 1st gear grunt. You would think they would be reading tone wheel for ABS vs. counter shaft rpm wouldn't you? Not all bikes/markets have ABS I guess. Or maybe I am not a motorcycle engineer and am just speculating on best way to determine speed of a motorcycle. There are speedo correcting devices available.

I guess what makes me laugh the most is my previous observation: my old Virago speedo is spot-on according to GPS and the radar "your speed is" devices around town. Go figure.

Even more bizarre is the claim the odometer is accurate. I have not verified that personally.

I'm certain it's from a liability standpoint. Or maybe making us play nice. It doesn't seem to matter the brand or vehicle type...

Just checked my 2017 Wee with my Zumo. It is out exactly 5% across the range - 95kph actual on 100kph indicated (or 57mph on 60 indicated).
