I checked the profile and saw the OP is Female, I made an assumption, so I'll add.
#2 Pull up you Big Girl Panties.
#3 You won't be offended by people saying the 883 or a Sporty is a Chicks Bike, you are one.
How long have you been riding?

This is serious, from experience, novice riders tend to ride slower because the sensation of speed is new. I rarely look at my speedometer unless I'm in a speed trap area or setting the cruise. Ride with the flow and time should not differ.

 

Get this app velcro or tape it right under your Speedo, the numbers are big very easy to read while moving. DigiHud Speedometer it works great and is very accurate.

 

You must be one of the lucky few because every Harley I've ever had with the stock setup has been off 3-5%.

 

My Avo (Gram) can out ride you from her grave. Real talk.

Rock & Troll, baby!

 

Having read the better part of both threads now, my advice to you is to sell the bike and buy a pretty pink Barbie car. A convertible maybe, so you can still feel the wind in your hair but without all the whatever it is that bothers you about motorcycles going on.

Or, keep the bike. Go back and revisit your posts, show some interest in the topics that YOU started, and attempt to learn something.
