I've ridden a Honda NC700, I despised auto mode as it shifted when I wasn't expecting it. You can even do it with a synchromesh domestic h-gate but it's really tricky and the synchromesh works against you.Ī dual clutch transmission has to guess where you're going next and if you do something unexpected like downshift where an upshift is expected it can be slower. You have to go pretty hard to do that, particularly on the downshifts that don't work clutchless at pottering around town rpm. Get it right and it's really smooth.Įarly 90s f1 paddleshift sequentials were essentially big motorcycle gearboxes with a pneumatic actuator, before then even on h-gate racing boxes you slip between gears with a throttle chop although a sequential shift drum make the diagonal shifts easier. This is exactly what you've got on an a pre-efi bike, modern ones can add electronics to chop the throttle but the shifter is direct mechanical input. The basic idea is you unload the transmission with a brief spark/fuelling interrupt (or on older systems chop the throttle) and at the same time load the shifter and as the load passes zero it makes a very fast shift. A synchromesh gearbox is a constant mesh gearbox that uses synchronizer rings to help engage the dogs more easily.īecause they usually don't declutch to shift, so it's a lot of extra weight. What I should’ve said is both types of manual transmissions are constant mesh not synchromesh. Kind of a difficult concept to describe in words, I would recommend YouTube videos with diagrams if curious.Įdit: Thanks for several people for the correction, I made a mistake. In both cases, the transmissions are synchromesh designs, where the input/output gears are always in mesh with each other and ratios are selected by engaging “dogs”.Īutomatic transmissions in the conventional sense use planetary gear sets with different clutches to engage different gear ratios. ![]() These are also found in motorcycle gearboxes. In a sequential transmission, the shift forks are operated by a spinning column that will force the gears to engage only in order. In an H-pattern manual, the shift lever can be used to operate whichever shift forks you want, meaning you can select any gear at any time. The difference comes from the way the shift forks are operated. Other sites that can provide excellent information: Abusing this though will result in a ban.
