All, on the BMW G650 series the speedo has an error of over 10%. 120 kmh on my GPS meant something like 135kmh on the speedo. I found this to be very irritating. To solve this I had a friend of mine lasercut an new speedo rotor for the BMW G650X with 44 instead of 48 slots. Later on I found on the Xchallenge you can set the speedo on a different wheel diameter (of the Xcountry to be precise) and make it spot on accurate. However, on the Xmoto and the Xcountry you can't, as it is already set on 17", and you have no smaller choice. Just recently I had someone with an ABS equipped Xcountry test this speedo ring, and they proved to be nigh on perfect. Speedo error withing 2%, and the ABS still works flawlessly. Here's what they look like: Left stock, right custom recalibrated ring. The rings come in galvanized steel and wont rust. the first series (well "series", there were only 10 or 11 of them) have all been sold. My question to you all, are any owners of a BMW G650X interested in one of these. Price will be between $40,- and $50,- including shipping worldwide, depending on the amount I need to have made. Interested? Please let me know and I could pull off a new series.
