Do any of you wonder about the accuracy of your GW speedo? Aside from using a stop watch between mile markers with your cruise set at 60, it seems like the Speedo Healer would be the answer. However, my snomobile buddies tell me to get a GPS. They use them all the time for checking their speed (and not getting lost). Any comments from users of either?

I have a GPS and use it all the time. The speedo on the bike was always 4 to 5 mph off at highway speeds. The last time I replaced the rear tire I put a 70 series on and the speedo reads true now. I am unfamiliar with the Speedo Healer. The GPS always reads the correct speed but lags behind a bit, takes it a couple seconds to catch up.

Do you guys have a particular brand and model of GPS that you prefer?

I am more concerned with how much it's off than correcting it. Actually with the unmentionable tire I run it is about perfect. I had a police officer shoot me with radar to check it and it's right on the money. I also checked against 50 miles of interstate mile markers and the ODO was within 2/10ths. With the original tires it was off 2 miles in the same 50.

I use a GARMIN StreetPilot 2730...absolutely love it !!!

The speedo on the wing runs about 2 mph faster than the GPS.

I use the StreetPilot 2710, works well for me. Only about 3mph off at 70mph on my bike. Since my Interstate only has one trip meter, I like the 4 additional trip meters built into the GPS. The 2xxx series are all waterproof, touchscreen, plus 4 multifunction hard buttons. Day/Night viewing, etc. I think the 2720 doesnt get used much for motorcycles as it uses a spinning hard drive like a computer, but the 2710/2730 use a Compact Flash card for memory. A 2g CF card will get you the whole United States and Canada on your bike.

I have a Street Pilot 2720 and have never had any trouble with it. I got it when I had my 89 and then transfered it over to the 08. Had it about 4 years now. They have smaller units with bigger displays now, but they get very pricey. Some guys run the less expensive units that are not waterproof and just cover them or put them away when its raining.

Even the cheapest gps will give accurate speed.. it may lag a second or two if changing speed because the algorithms average a few points..

I've found that the less expensive units seem to have slower CPU clock speeds.

My Garmin Nuvi 350 which is only a few months old, will announce a turn about 2 seconds after I have already passed the intersection at 60 mph.

My Garmin 2730? Even at 100 mph, that thing is ahead of you all the time, and within 100 feet of passing an intersection at 40 mph, it will announce a corrected route.

I wish we could get better specs on those things before we buy them. Like CPU clock speeds or rate of recalculation.

An inexpensive option is a digital bicycle speedometer. Once calibrated they are very accurate. About $10.
