Hey guys,
Hope you all had a good weekend of riding!!!! I took the trip to Collingwood up 27 from Toronto, and then Airport Rd. down to Mayfield and the 410 the rest of the way to Oakville...awesome awesome awesome! I enjoy putting around town during the week back and forth from work and regular commuter things...but this ride just made enjoy the bike more than I expected! There were a ton of riders on Airport Rd and it was good to enjoy the weather!

Now to the topic...I put my GPS into my tank bag (through the plastic film) in order to see how effective it is...not bad but need to take my eyes off the road for a few seconds to see what's going on and when/where to turn...but when I turned on the gps to show speed...there actual speed was about 8-12% lower than indicated. Could be the GPS so I'd need to try another one to confirm, but is this normal for bikes? Any fix for this? Or just do the math in your head each time? IE: 100kph indicated was 90-92kph GPS.
