I have a 08 ultra; does your speedometer seem to be accurate? ( high or low)
Mine seems to read about 5 miles over what Im doing.

You are most likely right. I have 2 Harleys and both run about 4 miles per hour slower than indicated. This is according to my Garmin GPS and the Ohio State Highway Patrol...[:'(].

Ride Safe,

yaeh mines bout 4mph off but i consider that pretty good. wierd thing happened today tho. looked down and my speedo was jumping around drop/rise ect..stopped tho hasnt happened since.

 

I hate finding out like that.

 

Mineshows 4 mphfaster that actual speed according to those portable "show your speed" radar signs that police put around.

 

Now yer gonna make me take my Garmin NUVI and have the old lady hold it while we ride so I can check out my 08 to see if its off any.

 

Almost every bike I've seen runs about 4 miles per hour slower than indicated. However, I used my Garmin this past weekend when I rented an '07 Ultra and found it was only 2 miles per hour fast on the speedo and about 2% (2 miles per hundred) fast on the odo.

 

Mah '07 UC shows 'bout 2 mph faster than indicated by GPS...

 

Have 07 Ultra and mine is also about 4 + mph off...

 

Don't bother its off, unless your looking for personal satisfaction (of courseI would love to be wrong). All my bikes were off. whenI inquired they said HD does not calibrate unless it is a bike used by Law enforcements, then they will calibrate. I just use my conquest as my true speed. My Ulta is reading 73 mph fast at 70 on the GPS.
