Speedometer error

Today I checked my speedometer against a GPS and my suspicion was confirmed. The speedo reads 5 mph high, pretty consistently. So...that means my bike really has more miles than indicated and I guess it also means my gas mileage is a bit less than I thought. I don't suppose there's any way to calibrate these things.

Saving my pennies for an ST 1300, but I don't see that happening any time soon.

Not.

Many tests by owners have shown that although the speedometer is off (by approx 10%). The odometer is not.

I Checked mine with a GPS and by using mile markers...it's true.


And have you considered a Yamaha FJR 1300 instead?

The oversize front tire puts the speed almost dead on.

I've researched both bikes and while the Yammer is certainly a fine machine - and it has a few features the Honda doesn't - I'm still drawn to the Honda. When I'm actually ready to make a move I'll take another look at the FJR. What do you like about it better than the ST? I think you and I have had this discussion before. Thanks for your input.

No. I run the 110/90/19 front tire. The 110 tire is .7 inch bigger in outside diameter than the 100 tire. The speed and miles are dead on with the GPS.

I can go into detail here, as I too researched both bikes.....actually all the bikes in this category at the time....for almost 2 years. It came down to these two in the end. But here are a few bullet points.

First off, the Yamaha is faster. With 145hp (at the crank) it's a clear winner in any performsnce test. Need to pass that semi? It's over before you know it.
Side by side, the Honda looks and feels bigger. Sit on each and the Honda looks huge compared to the FJR. And it is in fact a heavier bike...
The FJR luggage system is much nicer. The bag liners make packing for a trip easy. And only the Yamaha comes with covers for the tail section if you want to ride without the side cases on...and not have the bike look like they are missing.
That tail section under the passenger seat also provides s lot of storage, as does a tool section under the pilots seat. I carried full set of sockets, ratchet, whole set of combination wrenches, Allen set, tire repair kit and an electric pump under the seat, not needling to take room in a side bag.

Both bikes have very good brakes, but the FJR's are just a bit better. (Both have ABS and braking tests I've read favor the Yamaha)
The suspension on the FJR is more tunable.... And I've heard it now comes with those awesome heated grips as standard equipment...along with inverted forks.
Honestly both are great bikes, the Hondas fairing does make it look a bit more like a scooter than a sport bike, but both fairings protect the rider well.

If I was to buy another Sport Touring bike, I'd get another FJR. But after owning one, I guess I'm just jaded now...

The new ES model looks to be a winner:

And

But of course, everyone has their own list of what they like or need.

Forgot about that. Cool! I'm getting better than the 42mpg I always come up with.

I think the mph was -1 of the gps when I checked it, with the big tire.

Get the over sized tires and your speedo will be true. Also the Sportster will beat most anything on the road.
