As a factory option, the BMW Gear Shift Assistant Pro is offered. It makes it possible to shift up and down while riding in the appropriate load and rpm speed ranges without using the clutch or throttle valve.
Does this imply that if you’re within certain RPM range, you can tap up or down? What happens when the range is exceeded? It sounds almost exactly like a car’s paddle shifters.

I’ve been tinkering with my 2015 R1200R. I purchased the bike with the knowledge that it lacked Shift Assist Pro. Though I now have my doubts about that!
By preloading the gear level and gently easing the throttle to engage the next gear, I often upshift. This initially seemed a little rough, but I put it down to the fact that I had to fine-tune my technique for using a boxer engine in general and this bike in particular. Downshifts have always involved a clutch-blip-shift technique (personal preference).
But a few times as I preloaded the gear lever, the bike began upshifting on its own. At first, I attributed it to either a) hitting the RPM sweet spot to naturally shift into the next gear or b) subconsciously easing the throttle to allow the shift.
This has occurred a few more times, which inspired me to conduct a few tests. Up to gear 6 (I’m not sure about 1->2 because I just can’t bring myself to do that to the gearbox), I can happily shift up without ever using the clutch or the throttle. Every time I upshift, I can hear a pleasant little gurgling coming from the exhaust. I’ve tried it moving down the gears, but it doesn’t feel nearly as good as I anticipated.
How do I tell if I’m simply butchering the gearbox or if it is Shift Assist? Although it contains the Comfort, Touring, and Dynamic packages as well as driving modes pro, D-ESA, DTC, and the On-Board Pro computer, Shift Assist Pro was not listed when I ran the VIN through the BMW checker. Perhaps a refit that was not disclosed to the seller?
According to the current Motorrad configurator, the Dynamic package includes the Shift Assist Pro. Was this still true in 2015?

When riding alone from first gear up, I prefer to use shift assist pro. I rarely use it in the lower ratios when my wife is with me. It works best while riding aggressively in lower gears. If you ride carefully, clutch gear changes in the lower speeds go more smoothly. However, it would be beneficial if you could turn it off. Even now, I have the habit of loading the shift lever before depressing the clutch, which occasionally helps me before I want to shift.
If everything else was equal, I would choose a bike with shift assist pro over one without.
For changing gears with essentially no disruption in power flow, use the optional Gear Shift Assistant Pro.
Another first in the history of manufacturing production motorcycles is the BMW Gear Shift Assistant Pro. The functionality of the Gear Shift Assistant, which is already present on superbike models like the BMW S 1000 RR, has been expanded for usage on the new R 1200 RT and tailored to the unique needs of a touring bike. In the load and rev speed ranges relevant to riding, the Gear Shift Assistant Pro enables upshifts and downshifts to be done without action of the clutch or throttle valve, boosting rider comfort and adding a dash of dynamic. The Gear Shift Assistant can assist with the majority of gear changes; starting is one of the few instances where it cannot.
The power can continue to flow with barely any interruption while accelerating because the throttle valve is no longer required to be closed during gear changes. Additionally, automatic double-declutching is employed to modify the engine speed when accelerating and downshifting (throttle valve closed). The footshift lever is used to engage gears in the typical manner. Comparing shift times to clutch-operated gear changes, shift times are significantly faster. The Gear Shift Assistant is merely a tool for changing gear; it is not an automatic shift system. For safety reasons, the cruise control is turned off automatically when gear changes are made with the aid of the Gear Shift Assistant.
The assistance mechanism is activated by a sensor on the gearbox output shaft, which picks up the rider’s request for a shift. The burden on the powertrain is efficiently alleviated by raising or decreasing engine torque by the necessary amount, allowing the shift dogs of the following gear wheel pair to mesh similarly to when the clutch is engaged. While using the clutch, while shifting up with the throttle valve closed (overrunning), while accelerating, or when decelerating, no gear shift assistance is offered. When shifting up or down, no help will be provided if the shift lever is not in the correct starting position.
Downshifting with the throttle valve open is assisted, although doing so might cause strong load change reactions, especially in low gears. When traveling at a constant speed and shifting down without using the clutch, the same result may be obtained. Therefore, in certain riding circumstances, BMW Motorrad advises always utilizing the clutch to change gear. Additionally, riders should refrain from using the Gear Shift Assistant at rev ranges near the red line.
What is gear shift assist pro for BMW motorcycles?
In practically all load ranges and engine speed ranges, the shift assistance Pro enables up- and downshifting without clutch control. So, the assistance makes sure that shifting periods are substantially shorter, the clutch hand is relieved, and thus, comfort and dynamics are improved.
The suggested retail price is *. Labor and supplementary fittings may be more expensive.
How do bicycle quick shifters function?
A sensor detects the gear shift movement, a microcontroller (CPU) interprets the data (and determines the time), and a momentary ignition cutoff results in a reduction of the load at the transmission, allowing the new gear to slip (and engage) into place. This is how nearly all quickshifters operate. However, there are other ways to detect the load and reduce it.
Has the BMW S1000RR launch control?
In order to prevent wheelies, the launch control consists of a wheel torque reduction above ground speed while the bike is stationary on the grid.
At a complete stop, while the engine is running and in 1./2 gear, the Start button must be pressed for three seconds to engage the Launch Control (see video). L-con is not visible in the instrument cluster of models made before 2015, but once the L-con is activated, the DTC check lamp turns on. After then, by twisting the throttle, the engine speed will halt at the designated RPM. The launch control can be turned off by pushing the start button three times in a row, turning the ignition off, changing the riding mode, or during a race by shifting into third gear or leaning more than 30 degrees.
To make things even simpler for the rider, the launch control on the M/S1000 starting in 2019 (K6x) engages immediately after programming our Race Mapping PRO. Deactivation takes place as previously said. For disassembly, we produced a video (see here).
The stock engine speed limit is 9.000 rpm, and the speed threshold for deactivating the engine speed limit is set at 70 km/h. There are no adjustment options available through the instrument cluster. The thresholds for our race mappings are 9.000 rpm (K46), 7.000 rpm (K47, K49), 7.500 rpm (K6x), and 60 km/h.
Which bike has an automatic Blipper and rapid shifter?
Modern car engineering has given us quickshifter and auto-Blip. They gained enormous fame when Kawasaki unveiled its 2020 ZX 10R model.
With a Quickshifter, is the clutch necessary?
Riders must roll off the throttle, draw the clutch, tap the gear lever, release the clutch, and then twist the throttle once again to shift gears while operating a motorbike. The rider doesn’t need to touch the clutch or throttle at all when using a quickshifter. Simply tap up with your foot, and the quickshifter will take care of everything. The bike is speedier and performs better since there is less human interference.
How does auto Blipper work?
We looked at how to shift up on a motorcycle without using the clutch last week. But is it feasible to shift down the gears in the same way? If you pay careful attention to MotoGP, you may have noticed that riders have been downshifting without drawing in the clutch lever for a few years now and that road motorcycles have also started gaining bi-directional quickshifters. Consequently, what precisely is the technology and how is it possible?
You must first perfect the technique of using the clutch when downshifting in order to understand how clutchless downshifts work. You must comprehend the idea of rev matching, sometimes known as blipping on downshifts. In a higher gear and vice versa, the engine RPM is lower for a given road speed. As a result, the engine revs up quickly when you shift down and let off of the clutch, sending a significant back torque to the rear wheel all at once. If the clutch is engaged suddenly, the operation can be rather jerky and the rear wheel may even momentarily lock up.
Simply blipping the throttle while the clutch is engaged and releasing the clutch lever will smooth this out. This prevents a jerk when the rider lets go of the lever by increasing the engine RPM to a point close to where it will be once the clutch is released. In conclusion, engage the clutch, downshift while blipping the throttle, and then let off of the clutch lever.
The clutch lever can be completely eliminated from this technique if done correctly. When downshifting, the shift lever typically moves downward, deselecting the gear that was just selected before selecting the next one. A successful downshift can be made even without pushing in the clutch lever if the throttle is lightly depressed during the intermediate phase when no gear is picked.
To begin the downshift, push down with your left foot. Halfway through the shift, briefly blip the throttle. The next gear should fit in with no resistance or problems if the timing is right.
It was only a matter of time before a small computer started managing all the timing for you because rider aids are becoming increasingly intelligent every day. Simply depress the shift lever on a bike with an auto-blipper, and the ECU will automatically blip the throttle at the proper time, selecting the next gear smoothly and effortlessly.
Use of quick shifters in MotoGP?
The most technologically sophisticated motorbikes on the planet, MotoGP bikes come equipped with features you won’t find in your typical road motorcycle. You might be curious as to whether MotoGP bikes have quick shifters given how quickly the riders can shift gears.
For quick and seamless gear changes, MotoGP bikes do have a quick shifter that is linked with a seamless shift gearbox. Riders can shift gears thanks to this without releasing the clutch or lifting off the throttle, and they can do it even at high speeds and lean angles of more than 50 degrees while cornering.
Given the high cost of construction, it is not surprising that the transmissions on MotoGP bikes use some of the most cutting-edge technologies. We’ll go into more depth about how MotoGP racers use their seamless shift transmission and speedy shifter below.
Is there a quick shifter on the S1000XR?
Dynamic Electronic Suspension Adjustment (D-ESA) is now standard, even on the base model, thanks to springs designed for a rider weighing 75 kg, but D-ESA Pro is only available on the S1000XR TE or as part of the base model’s PS1,250 “Dynamic Package” (which also includes cruise control, keyless entry, quick-shifter, and more).
