I have run the RB on mostly my Italian bikes, i did do the RB Easy for the RC390Cup, and planned on getting a "racing" version to take advantage of all the features, map select, quickshift, pit limiter(which is awesome on the street for the PoPo, when you see one, hit the button, locks you in at a predetermined speed without brakes or nose drop),etc. I have decked out my RC with a lot of great stuff, as soon as I get the RB, I will chime in on what I found make it run right. Cooler and more power is my goal. What I can say is on my MV F3 & F4 RC bikes, It WOKE THEM UP BEYOND MY DREAMS. I love their systems, but like you all have reiterated, a MANUAL wouldnt hurt them at this point to understand their units and thinking. RB are easy install and works nearly out of the box. Playing with it, so far without a real manual, hasnt rendered me anything but time wasted. RB makes these things for all vehicles from tractors, cars, trucks, diesels. Vast applications, but nobody has pressured them to get a manual together. That would resolve a lot of time spent on finding out stuff that we should have printed upon the purchase of this great product.
