Hi, was thinking out of putting a quick shifter on my 2009 blade, but have heard from one person that they can damage selectors and dog teeth in gear box. I would do mostly road riding with occasional track day. Any advice on the subject would be grateful.
Personally HM all day long.. bit more money but heard so many good things about them seems to be the only choice imo
Been thinking of getting a QS for some time now but like L.C HM would be my only choice probably the seamless shift version (or GP if selling my kids was legal!). In terms of damage been clutch less upshifting since I care to remember w/o any issue just would like to do it fully pinned w/o releasing the throttle!. I've read bits and bobs about different version of QS not completely unloading the transmission so causing damage but I'm no expert...
What I would be most concerned about is if they cause any damage to gearbox. I think what I really want to know does anybody use one on there road bike and if they have had any problems with there gearbox caused by using a quickshifter.
Ive rode hundred/thousands of miles with the HM no problem, someday I will pull my gearbox and take a look, the joy of cassette gearbox on 07, worst thing a shifter can do is have too long a kill time with heavy lurching as a result of too long of times in the upper rev range, this will snatch the gear box and cause possible damage, likewise with times that are too short, grinding gears when trying to engage a gear. HM has good gear detection with adjustable kill times for clean shifts, no moving parts, simple and very effective device. Many many people run them on the road and on track, I have never heard of gearbox problems related to the use of the HM shifters.
Another question from a quick shifter novice,are they any good going down the gears? I have a 2013 with a slipper clutch and its the HM GP that i'm saving for
Get asked this all the time, the GP has an output for a blipper, it's the blipper that "blips" the throttle for down shifts when the peddle is pressed, a few aftermarket blippers for the blade do exists but I have no experience of them. Some fly by wire bike support blippers with the stock ECU, the R1 I believe is one of few, not the likes of the 1199 or BMW etc. In short the HM GP supports downshifts IF you have a blipper fitted or your ECU supports it. The blade has no blipper feature standard. Tech note: a blipper is a mechanical servo or selonoid that opens the throttle automatically fly by wire bikes have a servo that opens the throttle already, when the rider turns the throttle tube on a fly by wire bike it's the ECU that opens the throttle on the engine, not the rider.
From the BMW press release posted elsewhere on these boards: Optional Gear Shift Assistant Pro for changing gear with virtually no interruption in power flow. The BMW Gear Shift Assistant Pro is another world first for production motorcycle manufacture. Compared to the Gear Shift Assistant already featured on the superbike models such as the BMW S 1000 RR, the system?s functionality has been extended for use on the new R 1200 RT and adapted to the specific requirements of a touring bike. The Gear Shift Assistant Pro enables upshifts and downshifts to be made without operation of the clutch or throttle valve in the load and rev speed ranges that are of relevance to riding, both increasing comfort for the rider and providing an added touch of dynamism. The majority of gear changes can be carried out with the help of the Gear Shift Assistant ? starting off is one of the few exceptions to this. When accelerating, the throttle valve no longer needs to be closed for gear changes, allowing the power to flow with barely any interruption. And when decelerating and shifting down a gear (throttle valve closed), automatic double-declutching is used to adjust the engine speed. Gears are engaged in the usual way with the footshift lever. Shift times are considerably faster compared to gear changes with operation of the clutch. The Gear Shift Assistant is not an automatic shift system, but rather just an aid for changing gear. When gear changes are carried out with the help of the Gear Shift Assistant, the cruise control is automatically deactivated for safety reasons. The system works by employing a sensor on the gearbox output shaft to detect the rider?s shift request and trigger the assistance mechanism. By increasing or reducing engine torque by the required amount, the load on the powertrain is effectively eliminated to allow the shift dogs of the next gear wheel pair to intermesh in the same way as when the clutch is used. No gear shift assistance is provided when changing gear while operating the clutch, or when shifting up with the throttle valve closed (overrunning) or when decelerating. Neither will any assistance be given if the shift lever is not in its proper starting position when shifting up or down. Assistance is available when downshifting with the throttle valve open, but this can provoke severe load change reactions, particularly in low gears. The same effect may be produced when changing down without operating the clutch while cruising at a constant speed. BMW Motorrad therefore recommends always using the clutch to change gear in these riding situations. Riders should also avoid using the Gear Shift Assistant at rev speeds close to the red line.
