Those of you that follow Moto GP closely often come up with question that what exactly is the technology behind riders downshifting without pulling in the clutch lever for a few years now, and road bikes have been getting bi-directional quicksilver too.
The hidden concept lies in the art of using the clutch when downshifting and you need to understand the concept of rev matching or blipping on downshifts. The engine RPM depends on particular road speed and is lower in a higher gear and vice versa.
The rear wheel receives a significant back torque and when you shift down and release the clutch lever, the engine RPM shoots up and it is generally a a jerky process if the clutch is engaged abruptly and results in even locking up the rear wheel momentarily.
The possible solution to this problem is simply blip the throttle with the clutch pulled in, and then release the clutch lever this smoothen out the process and as a result the engine RPM is brought up to approximately where it will be once the clutch is released, meaning you get jerk free ride when the rider lets go of the lever.
There is another method which is Clutchless Downshifts in which the clutch lever can be entirely eliminated from the process. During the downshifting of shift lever two process takes place it first deselects the previous gear and then selects the next one.
A successful downshift can be performed even without pulling in the clutch lever in the intermediate phase if the throttle is blipped when no gear is selected.
The process involve pressing down with your left foot to initiate the downshift and then halfway through the shift, momentarily blip the throttle which results in next gear slot in without any resistance or issue.
You cannot keep technology away from any field, so make rider aids smarter we have option of Auto Blippers which has simplified the process further.
The ECU will automatically blip the throttle at the appropriate moment with simple push down on the shift lever which ensures the next gear is selected smoothly and seamlessly.
