There are several ways to make something out of metal. The part can be stamped, cast, forged or machined. In fact, most motorcycle parts are a combination of more than one of these operations.
The chosen methods of metal working for a given part are usually based on economy of scale. If you are going to make a lot of a given part it is usually less expensive to have a set of dies made and cast it or forge it than it would be if you where machining it from a solid chunk of metal.
On the other hand, if you are operating in custom or small lot sizes then the CNC machines make a fully machined part not only possible but also cost effective. There is another reason to fully machine a part: if you need or want to possibly make changes to it design later on.
So what does all of this theory of metal production have to do with motorcycles? It explains why some would make billet heads and cylinders for their custom highly modified motorcycle engines.
When riding a motorcycle, we have to rely on one type of bearing or another. There are a few different styles of bearings employed in the smooth operation of any motorcycle. For instance, there are engine bearings - roller, ball and needle - that keep the internal components spinning in harmony. Wheel bearings allow the bike to roll down the road, and bearings on the front end allow the bike to turn.
The setup and maintenance of any bearing can extend or shorten its life, but especially so when it comes to the steering stem bearings of your motorcycle's front forks.
For the sake of this publication, we will limit our focus to the tapered roller bearing most commonly used since the introduction of the hydraulic front forks in 1949.
In 1885 Gottlieb Daimler patents what is generally considered to be the first true motorcycle.
Daimler, the automotive pioneer usually associated with building the world's first successful internal combustion engine (and, subsequently, the first automobile), staked his claim of priority in the two-wheeler world a year before developing his famous auto.
However, the idea of a motor-driven, two-wheeled vehicle did not originate with Daimler, nor was his the first such contraption to see the road. Sylvester Roper, who spent the U.S. Civil War working in a Union armory, built a primitive motorcycle as early as 1867. Roper's supporters - and he has more than a few - argue that he should be credited with building the world's first motorcycle.
Hundreds maybe close over thousand people lined up at Laan Kon Muang (the Civic Ground) outside Bangkok City Hall yesterday to get queue cards to buy discounted Royal yellow crash helmets bearing the emblem of His Majesty the King.
The first 10,000 helmets will be sold for the special price of 80 Baht per piece.
The Kawasaki Eliminator 125 embodies classic cruiser styling in a lightweight motorcycle with a low seat height and a friendly powerband. This makes it an excellent choice for new riders or anyone seeking an easy reach to the pavement.
Powered by an air-cooled, 125cc, four-stroke, SOHC, single-cylinder engine specially tuned for low and mid-range torque, the Eliminator 125 is perfect for around-town riding. The electric starter makes getting underway easy, and a convenient five-speed transmission allows the rider to use the engine's full potential.
The all new Suzuki Smash Revo, official this model is called the FK110SD-E model. I will agree that Smash Revo sounds commercially much better.
The weight and handling of the Suzuki Smash Revo is what you can expect from a 95 kilo, and a wheelbase of 1.23 meter. Nothing special about the handling of the bike, all we had the feeling that the 110cc engine was a bit more powerful then the average 110cc. Maybe the source for this extra power is the Mikuni VM-18 carburetor, the Mikuni VM-18 carburetor is often used in racing motorcycles. There are also special racing kits available for this Mikuni carburetor.
There's an increasing desire among riders to build their own dream bike, which is why we feature this story. And with scores of companies now offering motorcycle kits with a wide range of components and parts, that dream is fast becoming a reality.
While these companies offer a diverse selection of motorcycle kits, which vary from 'batteries included' to rolling chassis, it's easy to see there would be limitless options.
One's dream could easily overshadow what any market could supply.
Honda Motor Co., Ltd. held a groundbreaking ceremony to mark the start of construction of its new engine plant in Ogawa, Saitama prefecture, Japan.
