FINAL DRIVE

WATCH VIDEO



Chain, belt, or drive shaft. You wouldn’t buy a bike based solely on what kind of final drive it has, but it’s worth knowing how the systems differ.
If belts are so great, why don’t we see them on more bikes? Packaging and difficulty of replacement are the biggest drawbacks. Belts can’t wrap as tightly as chains so they need to be run on big pulleys that wouldn’t necessarily fit on smaller bikes. And when it comes to replacing a drive belt, the process usually entails removing the swingarm. Belts also sap a lot more power than sprockets and chains, so they’re not nearly as efficient.
Drive shafts must be the best form of final drive, right? Riders that have them on their bikes certainly think so, and BMW has been using shaft drive since 1923. Drive shafts are low maintenance, run clean, are impervious to rain and dirt, and—barring any sort of freak failure—will last the life of the bike. Those are important benefits, but shafts are also expensive to build, they weigh a lot, and they sap a lot more power than other final-drive systems. And you can forget about easy gearing changes.
That brings us to the good old chain and sprockets, which is far and away the most common form of final drive. As with most things that are mass-produced, cost is a huge factor, and chains and sprockets are cheap to make. They’re also compact, fairly durable, easy to replace, offer easy gearing changes, and are the most efficient means of power transmission. Yes, chains require regular cleaning and lubrication, tend to make a mess of things, are quite a bit noisier, and wear out much faster than belts or shafts, but you know what, every system has its drawbacks.

MOTORCYCLE ENGINE CLICK ON BELOW LINK TO WATCH A VIDEO  HOW ENGINE WORKS? A  Honda Super Cub  engine. The most popular motorcycle in history, with over 60 million produced. A  motorcycle engine  is an engine that powers a  motorcycle . Motorcycle engines are typically  two-stroke  or  four-stroke   internal combustion engines , but other engine types, such as  Wankels  and  electric motors , have been used in small numbers. Although some  mopeds , such as the  VéloSoleX , had friction drive to the front tire, a motorcycle engine drives the rear wheel, power being sent to the driven wheel by belt, chain or shaft. Most engines have a gearbox with up to six ratios. Reverse gear is occasionally found on heavy  tourers , for example the  Honda GL1600 , and  sidecar  motorcycles, such as the  Ural . The rider changes gears on most motorcycles using a foot-pedal and manual clutch, but early models had hand-levers. More recently, some have automatic or semi-automatic gear
