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.
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.
A BMW fast shifter is what?
By adjusting the ignition spark, the quick shifter can unload the transmission. The quick shifter lessens the strain on the drive train when you raise the lever to shift up a gear by either turning off the ignition or reducing the gasoline to the engine just long enough for the next gear to engage. The fast shifter enables the rider to maintain full power while shifting gears.
Has the BMW S1000R got a quickshifter?
The 2017 model has 5 kW (7 hp; 7 PS) more power than the 2016 model, with a maximum output of 123 kW (165 horsepower; 167 PS). Additionally, it weighs 6.6 pounds (3 kg) less than the previous model. It has updated exhaust, traction control, and an upgraded ABS. The S1000RR’s lighter frame and improved electronics were adopted.
Its performance is improved by the standard installation of BMW’s “Gearshift Assist Pro” quickshifter, just as the S1000RR.
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.
What does HP in relation to BMW motorcycles mean?
higher, quicker, and further Sport is renowned for being the world of superlatives. HP is also no different. However, High Performance demands more than just going higher, faster, and further. We are after all looking for the unattainable. And the starting point is not the finish line.
It’s all about sportiness, performance, and high-quality materials with HP. Setting new benchmarks and pushing boundaries are key. Long before the HP brand was created, the R 32, the first BMW motorbike, already reflected this attitude. Ernst Henne achieved record after record with the machine from 1923, earning her the nickname “the sporting jock.” Schorsch Meier made history in 1939 when he won the senior TT on the BMW Kompressor RS 500 TYP 255.
With the victory of the R 90 S in Daytona in the 1970s, Steve McLaughlin, Reg Pridmore, and Helmut Dahne made sure that there was a lot of controversy in the Superbike race. The success story was then continued by Hubert Auriol and Gaston Rahier riding the R 80 G/S over the desert and the impassable Paris-Dakar rally route. Following this, everything around BMW Motorrad Motorsport became quiet. The workers thought it was too quiet. Out of a passion for riding and motorsport, they therefore started things on their own. This marks HP’s beginning.
What functions does a slipper clutch?

You can support. There may be ideas on the chat page. (March 2011)
For performance-oriented motorcycles, a slipper clutch (sometimes called a back-torque limiter) was designed with an integrated freewheel mechanism to lessen the impacts of engine braking when riders slow down.
A slipper clutch’s primary function is to minimize excessive engine revs and rear wheel hop (or clatter), especially while a vehicle is forcefully braking (usually performance motorcycles). It accomplishes this by partially slipping up until a quick stop causes the engine to match the vehicle’s speed.
What are auto-Blipper and Quickshifter?
An auto-blipper allows you to change downshifts while a regular quick-shifter only works on upshifts. A down-shifter, on the other hand, needs a throttle input, which means that any device will have to take control of your bike’s throttle, taking that control away from you, the rider. The former, however, only needs the engine to be briefly cut.
I believed that the ability to develop an air-to-air missile guidance system demonstrated Gareth and the team’s capacity to produce dependable shifters more than a motorcycle quick-shifter, but he disagreed; “Failure of a guided missile system implies that nobody won’t be killed by it. If something goes wrong with an auto-blipper on a quick-shifter, someone could be killed.”
Despite numerous requests, Gareth has refused to put an auto-blipper into production even though numerous prototypes have been experimented with over the years. “He says, “I’ve designed electronics for a variety of businesses, and they do go wrong. Making something that is truly fail-safe is quite difficult.”
Since OE quickshifters are incorporated into the system when a bike leaves the factory, in principle they shouldn’t fail and the bike shouldn’t operate at all; “Denso, Magneti Marelli – they know what they’re doing and have teams of very experienced engineers… ECUs just don’t go wrong.”
However, Gareth created an aftermarket auto-blipper with a default mode that disconnects it from the throttle circuit after observing several competing devices on the market. Simply said, the device is not in the circuit that regulates the throttle position unless a downshift is being made. Other systems function by continuously observing what the rider does with the throttle, then transmitting that information to the ECU and supplementing it as necessary. The final signal delivered to the ECU, “open-throttle,” may still be maintained if anything goes wrong in that chain, such as a transient signal, processing error, or brown-out.
Any after-market parts must be extremely durable and properly built because the electronic environment in motorcycles is particularly hostile. Gareth has every right to be meticulous about the quality of each solder junction on the components for the quick-shifter.
“The failure of our system to remove itself from the throttle control circuit is theoretically impossible. The processor performs self-checks when you order a shift, and if everything passes, it will then insert itself into the throttle circuit. When it does this, it starts a “dead man’s timer,” which means that even if the processor somehow froze, the timer would keep running and still disconnect the circuit, making it impossible to maintain an open throttle. And all of this occurs in about a millisecond.”
Which BMW motorcycle sells the most?
Still out front is the boxer. The boxer models continue to be the foundation of BMW Motorrad’s success, having sold close to 80,000 units overall. With the introduction of the 1800 cc displacement R 18 engine in 2020, the already dominant position of the signature BMW Motorrad drive was further enhanced.
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.
Is the Quickshifter the same as a slipper clutch?
On a fuel-injected bike, the problem is that by the time the rider has engaged the clutch, rolled off the throttle, changed gear, and rolled the throttle back, the bike will pitch and dip, disrupting the handling, suspension, and geometry. Even clutchless shifts take an experienced rider 300 milliseconds on average to complete; yes, that’s a lot.
A slipper clutch basically prevents the back wheel from locking up while shifting down for a turn, i.e. from 4 to 2, and maintains the bike much more stable and prevents hopping, etc. The slipper clutch, in my opinion, will only be useful on a track.
For overeager riders going down the box, slipper clutches come in quite helpful since you can simply lock up while going down the box and once set up to the ramp, you can never go wrong.
Yes, ANY bike can upshift without a clutch; full power upshifts simply require a rapid shifter.
These devices temporarily turn off the engine, relieving the gearbox of some of the stress so you can change gears without reducing throttle. The key is to work the throttle as quickly as humanly feasible, which reduces the time required to change gear to typically between 15 and 50 milliseconds. Additionally to saving time, it won’t disturb the suspension, making the bike more stable overall and particularly in corners. Additionally, a constant throttle uses somewhat less fuel.
