It just doesn't work with reverse shift pattern (yet - until I apply some mechanical engineering design to get around its design limitation). The OEM quickshifter on my beast works seamlessly. In addition, because it is within the engine control ECU, it can detect the change in RPM that accounts for the shift being completed and resume power output the moment it detects that the shift has been completed, and/or it can detect the completion of the shift by seeing the sensor on the shift drum change state, as opposed to being a fixed preset time delay.ДЄftermarket add-on boxes.

How strongly you are pulling on the shift lever (It's a strain gauge, which is an analog input, not a simple 'if - then' switch that changes state at a fixed threshold)

Whether the clutch is slipping as a result of you pulling in the clutch lever (It knows what the RPM should be based on mathematics from the road speed and what gear you are in, and it knows what the RPM actually is) Whether you have the clutch lever pulled in or not (disable quick shifting if so) What gear you are in and what gear you are changing into As a result, it knows, and can account for (not saying they all do, but they can): I already wrote about my experience in post #46 of this thread.ДЄn OEM quickshifter is implemented within the engine control ECU. I'd rather ride with guys like that than the sterile, robotic types that look down their nose at anything not absolutely necessary and thus not pure. I'm glad there are people out there supporting the motorcycle aftermarket and wrenching on their bikes, no matter if it's just to be cool, for convenience or because they have some underlying medical issue that's none of my business. Why does it matter what rationale someone uses for modding their bike? I don't personally subscribe to some of the rationales given by others - shifting and clutch-hand fatigue, for example - for getting a QS but if that's their reason, more power to them. Was is really necessary for you do move from a 250 to a 650? Did the 250 not get you where you were going? Was it not capable of doing the speed limit? Why do you need 87HP when 24HP served you moving from point 'A' to point 'B' just fine? Are you using the street as a track? The list of things people do to their bikes is endless and, for the average street riders, not a single one is absolutely necessary. Carbon fiber bits and pieces like front and hugger fenders. We don't ride motorcycles out of necessity and virtually nothing we add to our bikes - save something like panniers if you want to tour or something - falls into the category of being absolutely 'necessary.' All motorcycles come with fully adequate front and rear brakes for riding on public roads fancy radial master cylinders and braided lines are not a 'necessity' either.

Having a 600+cc motorcycle is not a necessity for riding on public roads. Having a motorcycle is not a 'necessity'.
