If you’re considering upgrading your Harley’s engine, you should be aware of the different types of exhaust systems. In this article, we’ll look at the Comp-S, Parallel-Twin, and Desmosedici. We’ll also talk about what types of aftermarket exhaust systems are available for each type of engine. There are many benefits to each, and choosing the right one will make all the difference.
The Desmosedici Harley engine is a combination of two Ducati L-twins. The engine is also known as the Twin Pulse and has sixteen valves. It produces high power and torque. The Desmosedici engine is highly reliable and has been developed to meet the demands of a sports bike. Among other features, it is a Euro 4 homologated engine with a standard maintenance interval of 24,000 km.
The Ducati Desmosedici is a road-legal machine with powerful performance. This motorcycle is built for racing, and is also equipped with a race-inspired V4 engine and refined components. The Desmosedici RR is designed for expert riders, and is capable of track racing. Its powerful engine is paired with an aggressive riding position and adjustable suspension. The Ducati Desmosedici is available in two different color schemes.
The Desmosedici RR has an impressive 0-60 mph time. It also has excellent cornering manners. It uses the engine as a structural member, with the steering spindle mounted on a compact steel trellis. The rear swing arm bolts directly to the crankcases. The rear suspension is also highly adjustable, with both front forks and shocks adjusting to individual riding conditions.
The Desmosedici derived from the MotoGP Desmosedici engine has the same 90deg cylinder layout. Its rear bank of cylinders is rotated 42 degrees from the horizontal plane, which optimizes weight distribution. The design also makes it possible to have larger radiators. It also helps to shift the pivot point of the swinging arm forward. And the 81mm cylinder bore is the largest in the four cylinder supersport segment.
The Desmosedici RR is based on the MotoGP Desmosedici GP6 race bike. Its aggressive design and advanced technological solutions made it a standout contender in the 2006 Italian GP. Official test rider Vittoriano Guareschi was instrumental in developing the bike. A revised version of the Desmosedici GP7 was released in 2007 and was designed for the new race rules. It also featured a new Desmosedici RR based on the MotoGP GP7 project.
The Comp-S 2-1 full system from TBR features the classic stainless 2.1 cone system with welded Megaphone Gen II end cap. It also features stepped headers, which add substantial power and torque while accommodating the stock (12mm) O2 sensors. In addition, the 2-1 system features heat shields, which keep the engine cool. These parts are recommended for stock Harleys. You can find many Comp-S 2-1 full systems on the web.
The Comp-S exhaust is the ultimate exhaust system for a Harley. Its design complements Harley Davidson products and delivers unmatched horsepower and torque. This exhaust will add a thrilling rumble to your bike. The exhaust system also features a unique O2 bung and heat shields for protection. Adding a Comp-S exhaust system will add more power to your bike and make it sound like a true race bike.
The 61-cubic-inch knucklehead motorcycle engine is a transitional style between traditional and modern bikes. The knucklehead engine was designed to have a higher output and higher tech compared to the predecessor models. It was also characterized by polished rocker covers. As a result, it is easily identifiable by Harley enthusiasts. Despite its simple design, the knucklehead motorcycle engine has many characteristics that make it unique.
The Harley-Davidson Knucklehead motorcycle engine was introduced during turbulent times. In the 1930s and early 1940s, the world was undergoing the great depression, fascism was taking hold in Europe and the looming war clouds were gathering in Asia and Europe. Meanwhile, FDR was trying to keep the country from starving to death. The introduction of the knucklehead engine marked a turn toward the performance bike market. Despite a limited release date, Harley-Davidson sold three knuckleheads at an event held at the Schroeder Hotel in downtown Milwaukee.
In addition to being the mother of all modern motorcycle engines, the Knucklehead was also the first to use an overhead valve V-twin engine. The OHV style engine was known to have superior inlet and exhaust port aerodynamics compared to side-valve Flathead engines, which had larger, heavier breathing inverted-L-shaped combustion chambers. It was introduced in 1936 and was the company’s top-performing engine for several years.
Though the term ‘knucklehead’ was never officially used, the OHV engine became the popular choice of enthusiasts. Its distinctive rocker boxes and cylinder heads were what led to the name. However, in the 1950s, the term was adopted and has stuck. This OHV engine also has its own variant, the Panhead. If you’re wondering what the difference is between the two, check out the history of the Harley OHV engine to find out how it differs from the original.
The first production year of the Knucklehead Harley engine was marred by problems. Despite its 13 cooling fins, it still overheated. Although it had a poor gasket, it was still not effective at dissipating heat. Oil did not reach the top end of the engine and was unable to cool it properly. Another problem was the valve springs, which were an absolute disaster. A redesigned rocker set was sent to dealers to cover the output of the year.
If you’re interested in the future of motorcycle engine design, you’re in luck. The Big Four OEMs have come back to the parallel-twin design after years of neglect. From the late ’80s to 2008, manufacturers turned their attention to larger, faster, and more complicated motorcycles. Unfortunately, the crappy economy has affected the middle class in developed countries, as well as the motorsports industry.
Parallel-Twin bikes are very different than standard single-cylinder motorcycles, which have two separate cylinders. Inline motorcycles are smaller, but still contain two identical engines. Despite the similarities between these two engines, the most important feature is the firing order of the two cylinders. The inline engine has a crank angle of 360 degrees, while the parallel-twin has a crank angle of 270 degrees. This allows for more even firing, and more efficient fuel consumption.
Another difference between a parallel-twin and a V-twin engine is the sound it makes. The parallel-twin has a much higher peak efficiency and a smoother ride. The parallel-twin engine is also more efficient and durable. This difference is attributed to the fact that power is reduced below four hundred and one hundred rpm when compared to the single-cylinder. For example, a BMW G 310 R produces 33 horsepower at ten thousand rpm, but only six at nine thousand and five hundred rpm.
The Kawasaki 649cc parallel-twin engine is a popular choice among Harley motorcycles. This bike was introduced in the late 1990s and features a parallel-twin design. The Kawasaki engine produces 67 horsepower and 48 lb-ft of torque. This engine is also one of the largest in production. The motorcycles’ engines are highly efficient, and can reach speeds of eighty-five mph.
While the V-twin is extremely narrow, the parallel-twin is not. The parallel-twin can equal the V-twin in packaging. This is possible because of the parallel-twin design. By positioning the engine vertically next to each other, the engine goes forward toward the front wheel. There is ample space behind the actual cylinders for a parallel-twin design. Its compact design allows the motorcycle manufacturer to keep its engine in place, even with a V-twin.
