Speedo Accuracy?

Does anyone find their speedo on the optomistic side? I rode my wife's V back on a long trip & felt the displayed speed was too high. At a stop for fuel , I told her to maintain a constant speed of 120 km/h on the freeway ( she was in her car, stock wheels & tires). The displayed speed on the V was about 130-132 km/h when side by side. I know this was not a precise test but 10-12 km/h out is quite a difference. Any comments guys?

My speedo is about 4.5 miles per hour slow at 70. Seems to be a common problem.

2013 Vulcan Classic LT but may be going back in the fold..

hi iceman,

you are correct. the V's speedometer is indeed optimistic.
posted this on another site which confirms your suspicion.


the speedometer error on the V is about 8 percent over. checked against a gps unit (garmin 60csx) and observed the following :

gps / speedometer / @ rpm in sixth gear

1. 80 kph / 86 kph / 4000 rpm

2. 100 kph / 108 kph / 5000 rpm

3. 110 kph / 119 kph / 5500 rpm

4. 120 kph / 130 kph / 6000 rpm

It's universal... no telling why the bike manufacturers do this. Your tach is probably off, too. Yamaha refunded a bunch of people who found their R6's didn't really rev so high, a couple years ago.

I'm calm like a bomb!

Anyone have any ideas about a different tyre profile to make the speedo read more accurately?

Don't rush the goalie!
