Okay, let's get back to more serious stuff: choosing the right type of chain. This is no easy decision. After all, there are countless models and makes. As mentioned in Part One of this feature, you need to know the exact amount of power transferred to the rear wheel (refer to the owner's manual, your dealer or your manufacturer).

Then, using a chart, you can pick the chain model that is best suited for your bike. Every chain manufacturer offers low-end and high-end products. Therefore, your budget and your riding habits will also influence your decision. Do you race? Do you have to tow heavy loads? Do you regularly ride under the rain or with a passenger? In any of these cases, your engine needs to work harder and, consequently, it requires a stronger chain.

Many resources are available to help you make the right choice, starting with motorcycle websites. Various wholesale dealers also provide online catalogues, like Motovan (www.motovan.com/index_en.html) and Importations Thibault (www.importationsthibault.com). You'll find specific information regarding your own personal motorcycle or ATV.


As for drive belts, there's really no mainstream aftermarket solution out there. If you have to replace yours, simply ask your dealer. Belts can last up to 160,000 kilometers and, in my opinion, they prove to be a wiser choice. They require no particular maintenance, they're effective in dry or wet conditions and they're virtually silent and adjustment-free. Replacing a belt is fairly quick and easy, too.

One thing you have to make sure is to keep the right tension, otherwise the belt and gears may overheat and fuel consumption will increase. Using a calibrated tensioner is strongly recommended. If you're not properly equipped, just find a local mechanic you can trust.

Chains, on the other hand, require constant maintenance and regular lubrication (using a pressurized can). They also demand more frequent adjustments, especially when riding under the rain as water tends to make the lubricant disappear and the chain wear out more quickly.

Dirt bikes, enduro bikes and trials bikes should use silicon-based lubricants. The same holds true if you're riding on sandy or dusty terrain. The lower viscosity of these lubricants makes the sprockets and chain last longer.

Adjusting the chain
Adjustments and tension are key to a chain's longevity. Adjusting the tension of a chain also means adjusting its alignment. To help you out, markers can be found on the part of the swingarm onto which the rear wheel axle is attached.

Chain wear is very important when making adjustments. You have to lift the bike so that the rear wheel spins freely. As for tension, the technique varies from one motorcycle to another; you can either put the bike on its center or side stand.
