Surprising Speed: Indian’s Challenger Dominates American Factory Racing

Indian’s “Challenger” motorcycle has been making waves in the racing world, achieving impressive speeds and surprising everyone with its performance. This class of motorcycle, known for its heavy and long-wheelbase design, has evolved into American factory racing, and it’s gaining popularity rapidly.

The development of the Challenger has been a step-by-step process, focusing first on the significant gains before addressing smaller issues. This approach has led to visible technological changes from race to race.

The engine in the Challenger class is not regulated for cam lift and timings, resulting in a distinct V-8 sound when started. The engine’s life depends on reliable oil delivery to its plain bearings, which was achieved by designing a cavity behind the crankshaft to submerge the pressure pump’s intake.

The Challenger’s one-piece forged crankshaft with a single crankpin carrying two connecting rods side by side, and the primary drive from the crank to the gearbox is by gear. The drive to the rear wheel is through an S&S chain conversion.

Initially, the engine’s torque curve was planned to be “rainbow-shaped,” emphasizing midrange acceleration. This was different from the traditional torque curve of older two-valve big-inchers, which had peak torque at the bottom and decreased as engine speed climbed.

Compression ratio and head temperature play crucial roles in the engine’s performance. The cylinder heads on the Indian’s engine are CNC-ported, and the fuel used is VP’s T4, which is lead-and-ethanol-free but contains the oxygenate MTBE.

The exhaust system is critical, and the Challenger’s exhaust headers are additive-manufactured stainless pieces. Each cylinder has its own oxygen sensor, allowing it to be tuned separately.

The class has attracted significant attention from major American corporations due to its unique nature and the application of racing development techniques to motorcycles designed for touring.

Indian’s riders in this class are champion Tyler O’Hara and development specialist Jeremy McWilliams.

The key to the Challenger’s impressive 180 mph speed at Daytona lies in its mighty acceleration off the chicane and the power to push the wide front fairing through the air resistance. The bikes’ large V-twin engines and long wheelbases make them comparable to MotoGP bikes in terms of acceleration.

The choice of a 60-degree V-twin angle prevents piston skirt-to-skirt clashing as the large-bore pistons approach bottom center.

S&S Chief Engineer Jeff Bailey revealed that the horsepower of the modified engine is more than the commonly stated range of 155 to 165. The engine’s capabilities and the RPM limit set by MotoAmerica indicate its potential for further development.

The modifications made to the engine, such as the increase in bore size and the addition of a CNC-ported and additive-manufactured right angle bend for improved air intake, have significantly improved its performance.

Walt Siegl: Master Motorcycle Craftsman of Ducati Customs

Walt Siegl is a skilled designer and custom motorcycle builder originally from Austria, now based in New Hampshire, USA. He is well-known for his exceptional work with high-end Ducati motorcycles, creating unique and beautifully crafted custom bikes that combine classic looks with modern performance.

One of Walt Siegl’s most famous creations is the ‘Leggero’ Ducati, which is made-to-order according to each customer’s specifications. These bikes strike a perfect balance between style and functionality and are easily recognizable due to their distinct design. Walt built four Leggeros with the same template, featuring a chromoly WSM frame, Öhlins suspension, forged OZ Racing wheels, and Brembo brakes. The heart of these machines is a special Ducati motor built by Bruce Meyer, known for his expertise in Ducati engines.

The Leggero’s appearance pays homage to the timeless Ducatis of the late 70s and early 80s. The bodywork is both muscular and graceful, showcasing the craftsmanship of these bikes. Building four motorcycles simultaneously presented challenges, but Walt overcame them, resulting in the remarkable WSM Leggero.

Another impressive series by Walt Siegl is the ‘SBK’ series, which consists of made-to-order Ducati superbikes blending modern performance with classic style. These bikes feature aircraft-grade chromoly frames, custom-built engines, carbon fiber bodywork, and high-performance components, making them exceptional in both looks and performance.

Walt took on a unique challenge when commissioned by Bobby Haas to build a custom bike for the Haas Moto Museum. He decided to use the ‘square case’ bevel Ducati engine, often criticized for its design. Nevertheless, Walt succeeded in creating a track-ready machine out of a 1980 Ducati 900 SuperSport. The bike received numerous upgrades, including a performance-boosting engine tune by Bruce Meyers and a lightweight carbon fiber body, showcasing a vintage feel with modern materials.

Walt’s talents extend beyond Ducati motorcycles. He also customized an MV Agusta Brutale 800, drawing inspiration from vintage endurance racers. The bike, named ‘Bol d’Or,’ features custom-formed Kevlar composite bodywork, an aluminum subframe, and various performance modifications. Walt’s design perfectly captures the endurance racer aesthetic, and the bike performs exceptionally well on the track.

Lastly, Walt collaborated with industrial designer Mike Mayberry to build an alluring custom motorcycle using the drivetrain from an Alta Redshift electric dirt bike. They designed a new chromoly frame, custom swingarm, 17″ wheels, and Öhlins suspension and Brembo brakes. The bodywork was prototyped with cardboard and paper before being crafted from forged carbon fiber and compression molds, resulting in a one-of-a-kind machine with a unique appearance.

Yamaha R7: A Beginner-Friendly Beast That Delivers Power and Confidence

Yamaha recently released a new motorcycle called the YZF-R7, which brings back memories of the iconic YZF-R7 OW02 from the late 90s. However, the new R7 is quite different from its predecessor in terms of functionality, purpose, and design. Yamaha has shifted its focus towards prioritizing function over form, aiming to tap into and enhance the rider’s potential and capabilities for an exhilarating riding experience.

Although the R7 shares its engine with the MT-07, Yamaha has made several modifications to the throttle, tank, exhaust, and clutch to differentiate it from its sibling. Despite being based on the MT-07, the R7 offers improved build quality and a striking design that sets it apart from competitors like the CBR 650R and Ninja 650.

It boasts a stunning front-end view with LED daytime running headlights that can read your lean angle and ensure visibility. The M-shaped intake duct, reminiscent of the M1 MotoGP bike, houses the headlight atop the windshield, creating a distinctive appearance. The R7 stands out from the side with its blacked-out engine parts, complemented by a well-designed tank.

Yamaha aimed for slim proportions by incorporating a narrow parallel twin engine with the body neatly wrapped around it. Inspired by the YZF-R1, the sharp tail streamlines the rider and bike on the highway, making the R7 the narrowest and most aerodynamic bike in the R-Series. The CP2 parallel twin engine produces an impressive 49 pound-feet of torque and 72 horsepower in the middleweight segment. The CP2 platform, which has been tested and proven since 2013, offers superior mid-range performance and reliability. The R7 features a fully adjustable KYB fork, a notable addition missing from the MT-07, further enhancing its performance.

The R7 combines power and design to inspire confidence in riders, whether on the track or accelerating on the freeway. Its streamlined body improves aerodynamics and contributes to its sporty appearance. The power delivery is designed to provide excellent performance and fun during cornering and daily commuting.

The R7’s low-down torque prevents the need for high revs, making it suitable for riders who enjoy race-like riding styles without being professional racers. Additionally, with its competitive price tag of $9,000, the R7 offers great value for money compared to used motorcycles with similar features.

Fuel economy might not be a top priority for most sports bike riders, but Yamaha has also considered this aspect. The R7 provides a plush and stable feel on the road, particularly during urban rides. The fully adjustable KYB suspension and steep rake angle on the forks bridge the gap between the R7 and the MT-07, resulting in a more stable and rewarding riding experience.

The revised rear shock and new linkage lift the rear of the bike, shifting the center of gravity forward and placing the rider in a position similar to the R6. With only 72 horsepower, the R7 offers ample control, allowing riders to confidently maneuver corners.

To enhance braking efficiency, Yamaha has upgraded the braking system in the 2023 YZF-R7. It has replaced the standard calipers of the MT-07 with a Brembo branded radially mounted 4-part unit. These ABS-equipped calipers provide a crisper feel, consistent power, and prevent wheel locking.

Yamaha also offers special packs for the R7, such as the Adrenaline and Style packs, which include features like a fully adjustable Up-Side Down fork, quick shifter, and Billet front brake lever guard. These packs cater to different needs and further enhance the R7’s performance and style.

Despite its aggressive and racy appearance, the R7 is forgiving and not overly harsh. It is designed to instill confidence in riders, particularly those with less experience. The ergonomic triangle and clip-on handlebars create a sporty yet comfortable riding position, similar to the R6. The R7 is not a beginner’s bike but rather a beginner-friendly option that can be taken to the track.

From Ferrari F40 to Bugatti Chiron: A Look at the Evolution of High-Speed Cars

Throughout automotive history, several cars have pushed the boundaries of speed. In 1987, the Ferrari F40 became the first street-legal car to reach 200 miles per hour (mph). Nearly two decades later, in 2005, Bugatti’s Veyron hypercar broke the 250 mph barrier. Finally, in late 2019, the Bugatti Chiron Super Sport made history as the first production vehicle to hit 300 mph. However, one might wonder why it took almost 15 years to achieve an increase of just 50 mph.

The concept of speed may seem linear, but the challenges become exponential as vehicles aim for higher velocities. Andy Wallace, the driver behind Bugatti’s 300 mph run, explains that aerodynamic factors such as downforce, lift, and drag increase exponentially with speed. For instance, taking a car capable of 270 mph and pushing it to 280 mph requires significant efficiency improvements.

The main obstacle to achieving extreme speeds lies in overcoming drag, or air resistance. The force required to overcome aerodynamic drag rises at the cube of velocity. This means that a car requiring 200 horsepower to counter drag at 150 mph would need a whopping 1,600 horsepower to reach 300 mph – eight times as much power. However, creating a 300 mph car involves more than just a massive engine; it requires careful consideration of various factors.

Tires play a crucial role in ensuring safety at such high speeds. To withstand the immense forces exerted on the tires, Bugatti reinforced the last steel band of the tire with lightweight carbon fiber. This innovation prevented the tire from changing shape under extreme forces, maintaining stability. The tires were tested extensively at Michelin’s aircraft test center to ensure they could handle speeds up to 318 mph without warping.

Generating the necessary power to spin the tires is another significant challenge. Turbochargers are commonly used to feed more air into the engine, allowing for increased horsepower. The upcoming Hennessey Venom F5, expected to reach 301 mph, utilizes massive twin-turbochargers and achieves high RPM (revolutions per minute) for optimal power generation. High RPM enables faster air and fuel combustion, resulting in greater power output. It’s important to strike a balance between engine size, RPM, and efficiency to achieve record-breaking speeds.

However, the ultimate obstacle to reaching 300 mph is the resistance posed by the air itself. Drag increases exponentially, and the car’s design must minimize drag as much as possible. Koenigsegg’s Jesko Absolut, estimated to reach 330 mph, features a longer, flattened tail to ensure smooth airflow off the rear. Eliminating separation in the airflow helps reduce drag. Additionally, the car’s design eliminates excess downforce that would impede speed, replacing the massive rear wing with smaller tail fins and incorporating side vents to redirect airflow.

Advancements in testing have played a crucial role in pushing the limits of speed. Simulations that used to take a week can now be completed in a matter of hours, allowing engineers to quickly test and implement new solutions. As automakers continue to chase speed records, innovation and testing will remain key factors in achieving even greater velocities.

Bugatti may have already achieved the milestone of 300 mph, but automakers are constantly pursuing new records, pushing the boundaries of what is possible in automotive speed.

Six-Cylinder Bike: The Symphony of Lisbon’s Unik Edition

If you’ve never had the chance to hear a motorcycle with six cylinders in full throttle, you’re missing out on a true mechanical symphony. That’s exactly what Lisbon’s Unik Edition has achieved with their latest project—a café racer built around a screaming six-cylinder Benelli Sei.

The Benelli Sei may not be the most well-known six-cylinder classic motorcycle (that title goes to the Honda CBX), but it was the first production bike to feature a six-cylinder engine. Benelli introduced the 750 Sei in the early 1970s and later released the redesigned 900 Sei in 1979, boasting 80 horsepower and angular bodywork. Only 2,000 units of the Benelli 900 Sei were ever produced, and they came with a hefty price tag.

Tiago Gonçalves and Luis Gonçalves, the founders of Unik Edition (no relation), embarked on this project using a 1979 Benelli 900 Sei, but very little of the original bike remains. They stripped it down to its frame and engine, replacing or rebuilding almost everything else.

“Our goal was to create an incredible machine with six exhausts that is also easy to ride,” says Tiago.

To ensure they built upon a solid foundation, the duo thoroughly refreshed and tuned the engine. Having serviced several six-cylinder Benellis and Hondas before, they were well acquainted with these powerful motors. The Sei’s three Dell’Orto carbs now breathe through new pod filters.

However, it was during the modification of the chassis that things truly became interesting. They started by removing the factory subframe and fabricating a new one. They then made strategic cuts and reinforcements to the frame. The most ambitious modification, though, involved swapping in a single-sided swingarm from an early-2000s Ducati Monster S4R.

This required redesigning the rear end with a new shock mount to accommodate a modern mono-shock setup. It also involved aligning everything, from the swingarm pivot to the sprockets, to fit a wide 190 rear tire.

The rider is greeted by a digital Motogadget speedometer, neatly molded into the headlight housing. Motogadget also supplied the switches, grips, keyless RFID ignition, and bar-end turn signals and mirrors. The handlebars are from LSL, and the throttle is a Domino part.

At the rear, a tidy license plate bracket positions the plate behind the rear wheel without extending the tail section unnecessarily. It features a Koso license plate light and a pair of small Motogadget LED turn signals. Completing the build is the pièce de résistance of any six-cylinder custom bike—the exhaust. Unik Edition crafted a complete stainless steel six-into-six system, featuring three compact mufflers stacked on each side.
