Dynojet Quickshifterĭynojet quickshifter is easy to install and requires no additional wiring. It supports both ABS and non-ABS models and comes with a 2-year warranty. The module is shockproof and weatherproof and requires an Android or iOS app for setup and verification. This quickshifter also works in a reverse shift pattern and comes with Bluetooth connectivity. It is easy to install and has options to change the setting anytime via phone or wirelessly. Healtech’s quickshifter, iQSE comes with special ring sensor and wiring harness as per the bike specifications. There are many quickshifters available in the market which can be easily installed in the motorcycle to eliminate the need of any manual throttle or use of clutch during gear shifting. In older models of carburated motorcycles, the quickshifter interrupts the engine power by the help of spark cut. In positional sensing, the gear lever’s physical state is read and informed to ECU while in pressure sensing, pressure change on the drive train is sensed to generate ECU response. Some quickshifters employ positional sensing and another pressure sensing. The ECU here simply replaces the throttling on and off during gear shifting but approximately five times faster than manual throttling. This short time slot gives force to shift the next gear. The ECU then interrupts or cuts the ignition for less than 15 milliseconds. Upon pressure change on the shifter, the sensor senses a pressure change and informs it to the ECU. In most of the simplest design of quickshifters, the gear shift rod is relaced with another gear rod or fitted in-line with gear rod having a mechanical sensor, which is further connected to the motorcycle’s ECU. All it needs is a sensor and accessibility of ECU. Now the question is, how how to inform the engine and ECU (Engine Control Unit) about gear change. The quickshifters that assist in downshifts are known as autoblippers. Here the throttle is blipped to match the engine revolution with the lower gear, aiding in smooth gear engagement. Instead, in downshifting, the engine revolutions need to increase without cutting the engine power. Now, talking about downshifting, the logic here is completely different from upshifting. Here, the throttle is rolled off to disengage the drive train and select the next gear before getting back on the track. Many experienced motorcyclists and racers often cut short quickshift time with a clutchless upshift. Once done, the clutch is released to reengage the drive train and throttle is rolled again. This gives smoother control on shifting the next gear. This results in the reduction of engine revolutions and no power flow through the transmission. The clutch is then pulled in to decouple the drive train from the engine by momentarily cutting off the ignition or fuel in the engine. To change the gear positioning, the throttle is rolled off or closed (known as autoblipper, discussed later)Ĭoming to the sequence of actions while upshifting without any quickshifter: One type of quickshifter is designed for upshifting and the other one for both upshifting and downshifting. The same categorization applies to the types of motorcycle quickshifters. There are two types of gear shiftings, one is upshifting and the other is downshifting. To let know what actually quickshifting is, let’s discuss what really happens when you quickshift manually. Whatever be the reason, quickshifters now come in more number of bikes and in those without having quickshifters pre-installed, there are many third-party quickshifters available in the market which we will discuss later in the blog. Quickshifters thus eliminates the need for a manual throttling or clutch handling while making shifts. To some, this gives hand to rest over clutch and to some, it’s like being a MOTO GP star. This is why bikes have quickshifters, to make these shifts happen pretty fast, within 50 milliseconds or less. This causes a delay in making quickshift and it becomes more delayed due to racer’s concern on other tasks like body positioning, accessing corners and proper lines. Our brain’s perceiving power has a lag time i.e, there is a slight difference in when actually an act happens and when our brain perceives it to be happening. On average, an experienced motorcyclist takes around 600 milliseconds to make a perfect quickshift. Any delay in making these perfect quickshifts can make a racer lose a competition. This is where every second count and it becomes critical to make quickshifts happen fast to reduce to time for which rear wheel is not powered. Those few seconds to make quickshifts on a race bike highly affect the performance on the track.
