12 O'Clock Labs SpeedoDRD H2 Speedometer Calibrator

I went with this one instead of the HealTech Speedo healer as it’s less bulky and less expensive.A friend of mine had this on his CBR600RR as well and trusted it. So I figured to give it a shot.Once installed and went through MotoMummy’s website for install and setup, it worked perfectly!I opted for the calculated % error + the factory 5% error and it was +-1mph from a GPS speed indicator so I was pretty satisfied with it.I’m glad I went with this product as MotoMummy has always been good to their customers. Would definitely buy again!

I can finally know how fast I am riding again after a couple years of incorrect speedo reading due to a sprocket and chain swap. The installation was a breeze because the instructions were very well thought out and provided step by step plans. The recall feature is a nice addition that would be great for someone who does some track riding on the weekends.

Fixed an annoying problem.
