I figured that being able to design an air-to-air missile guidance system was more critical than a motorcycle quick-shifter, which proves Gareth and the team’s ability to make reliable shifters, but he disagreed “If a guided missile system goes wrong, failure means it’s not going to kill someone. But while the former just requires the engine to be momentarily cut, a down-shifter needs throttle input – this means that any device will have to take control of your bike’s throttle – taking that control away from you, the rider. What’s the risk of fitting an aftermarket auto-blipper?Ī standard quick-shifter only works on up-shifts, whereas an auto-blipper allows you to change down gears. You can do it by hand, but it’s a lot harder than a clutchless upshift. As you’re off the throttle, the rear wheel is driving the engine, so blipping the throttle increases the engine speed, and at the moment between the rear wheel driving the engine, and the engine driving the rear wheel, the gearbox will again float. In the same way that clutchless upshifts take advantage of float in the gearbox, to change down the engine speed required for the next lower gear needs to match that of the wheel speed. It’s a simple design, but it relies on a positive shift being made by the rider, and it takes away the direct feel of a solid linkage rod, as you’re introducing a degree of sprung travel to the system. A spring adds weight to that switch, but once compressed and contact is made (or broken, depending on whether the switch is normally-open or normally-closed), the force being applied to the lever is transferred to moving the selector inside the gearbox, and the next gear ratio is selected. In the case of the most common – an upshifter – as the lever is pushed up (on a race box it’s pushed down), the switch is first compressed and contact made. The factory-fit quickshifter on most current motorcycles uses a switch in-line with the rod that connects the gear-lever to the gearbox. What does a motorcycle quickshifter do? How does it work? Bubbles could also be an issue, so each device is meticulously sealed to ensure it’ll be as reliable on a race bike flat out in the rain as it will be on a road bike touring the Alps. The two-part compound must be applied in just the right way, in order to fully seal the electronics without fouling the button used in some units. The potting is done entirely by hand in a temperature-controlled room at HM Quickshifter.

We try really hard to make our products really easy to install and use.” And most of those are the result of a crash or an installation problem,” says Gareth.Īll of HM Quickshifter’s products are designed to be ‘plug and play’ “I’m of the school of thought that if you need a user guide, you’ve failed as a design engineer.

“We’ve been making the Quickshifter Plus for more than ten years, and the failure rate is something like 0.01%. The aluminum parts are locally sourced, and the highly specialized task of laminating the strain gauge to the machined part that sits on the bike’s selector rod is also done by Gareth and the team. When they come back, they’re each tested, wired up and potted (sealed in a waterproof compound) back in the small unit in Kent.

It was really interesting predictive mathematics.” This is a guy who knows how to make complex electronic systems.Īll design, programming and development is carried out by GarethĪll of HM Quickshifter’s products (their shifters, pit boards and dash) are designed, prototyped and programmed in house, then the circuit boards are subcontracted out for component mounting. Of the previous jobs he’s allowed to talk about, he designed the guidance math and electronics for an air-to-air missile “That was really interesting as the speed of the thing meant that you only had the opportunity for one directional correction – if you tried to correct it again, the G-forces would pull it apart. The company is led by Gareth Hopkins, who’s designed electronics since he was twelve, has a masters degree in mathematics and raced bikes in the late 1990s. Behind the door of this small industrial unit is a team of five that hand-builds the strain-gauge-equipped quickshifters found on the vast majority of race bikes around the world. So how does a quickshifter work, what does it do, and can it damage your gearbox? I visited HM Quickshifter in Sittingbourne, Kent to find out.

Touring, street bikes and even cruisers are all getting these devices, but they’re far from all the same from the most basic systems to full auto-blippers, they can feel completely different. Quickshifters have become commonplace on many motorcycles, and not just race bikes.
