Works as advertised. Took more time to unplug the speed sensor than to program the thing. Used the gps method on finding the percentage error and it was spot on. I couldnt be anymore happier with my purchase and for the best price on the net...thanks motomummy. I recommend for any rider that rides on the streets.

Very nice
Just finished installing this on my R1 after doing a 520 conversion and going -1 on the front. It was pretty easy to install and really easy to adjust. I would definitely recommend.

One of the best choices I can ever make. Easy installation and compact so you won't even notice its there. After 3 years, mines I had a glitch and I contacted 12oclock and they sent me a replacement with paid postage to send the other one back. Great product and great customer service.

I just installed this product and it works great! Super easy to install. It is easier to install/set-up than I imagined. Motomummy has links on the product page to a setup video and to the site that allows your to calculate your corrections. I would recommend buying this product, especially from Motomummy any day, if you have errors with your speedometer!!!

Thanks Motomummy.

This works perfectly, gives a top speed reading and sorts the speedo out nicely. I fit mine to elastic so it snaps in and out from under the seat. Pretty cool product!
