How To Interpret Motorcycle Spec Sheets

Whether you plan to customize your rig, need to make a quick repair or want to equip it with a more durable aftermarket part or accessory, you need to review the spec sheets to make sure that whatever change you make won’t affect its integrity or performance. By reading the specs beforehand, you can also ensure that you don’t throw away money on expensive OEM ATV parts or aftermarket motorcycle accessories it turns out you can’t even use. Don’t know how to read spec sheets? No problem. Keep reading to gain a basic understanding of these important blueprints.

Weight

Weight is probably one of the more important specs you’ll want to pay attention to before shopping aftermarket or Honda Ruckus OEM parts. Why? Because weight affects your bike’s power and speed. Lighter bikes are built for racing and therefore can achieve greater speeds, but they exert less engine power. Heavier bikes have more power but are more difficult to control. They’re also slow to gain speed. It’s important to know your bike’s weight class so you don’t inadvertently equip your machine with a component built for a lighter or heavier ride.

Power and Torque

Power and torque values tell you a little bit about your engine’s output. Horsepower refers to the rate at which your bike can perform, whereas torque refers to how well your bike can do things such as climb a hill or take tight turns. Before purchasing any bike parts—especially if they’re parts for the powertrain—make sure they’re designed with your engine’s needs in mind.

Compression Ratio

Compression ratio is another spec that tells you how powerful your engine is designed to be. This value informs you of how much power the pistons harness compared to the amount of fuel it uses. A higher value means your bike can exert more power for its weight, but it also means it produces more heat and stress forces.

Engine Architecture

Your engine’s architecture can tell you a lot about how it produces and distributes power. Two bikes with similar power profiles and specs can perform drastically different because of the way in which the engine was designed. Some factors you’ll want to look into is whether your bike is a two- or four-stroke engine, whether it utilizes pushrods or overhead cams, cylinder count and spacing.

Wheelbase

Wheelbase is another crucial spec, as this value tells you how well your bike can take turns and how stable it will remain at higher speeds. This number also determines your bike’s weight distribution when riding and informs you of how well your bike will handle when loaded down with the maximum weight capacity.

Carrying Capacity

Most people only consider their own weight when buying a bike, but if you’re buying a motorcycle or ATV for anything but racing, you should pay attention to this value. Do you plan to travel on your machine? If so, add weight for saddlebags and camping gear. Do you want to ride with passengers? Make sure you buy a bike built to handle two full-sized adults. The last thing you want to do is buy a bike you can’t customize for fear that you’ll weigh it down.
