Handlebar Recall On Nearly 1,100 Harley-Davidson Nightsters

Faulty welds on these Harley-Davidson motorcycles could cause the bars to break. by Dustin Wheelen from https://www.rideapart.com Harley-Davidson Nightster made a triumphant return to the Sportster lineup in 2022. We last saw the blacked-out bobber in 2012 as the Evolution-powered Nightster 1200 (XL1200N). Ten years later, the revived model benefits from the Motor Company’s new 975cc Revolution Max V-twin and an innovative under-the-seat fuel tank. Those technological advancements don’t eliminate all teething problems, unfortunately. On August 4, 2022, Harley-Davidson received a complaint from a 2022 Nightster (RH975) owner that the left portion of their handlebar broke off while riding. After performing warranty analysis and investigating the matter, the brand potentially received one additional claim related to this issue between August 5, 2022, and September 8, 2022. Harley then informed the U.S. National Highway Traffic Safety Administration (NHTSA) of the Nightster recall on October 6, 2022. According to the documents, a “weld quality issue” with the Nightster’s handlebar (Part No. 55801154) “could lead to separation between the inner and outer sections.” The consequences of such a failure need little explanation, but the recall lists that “a broken handlebar can cause a sudden loss of steering control, increasing the risk of a crash.” The Milwaukee manufacturer narrowed down the recall scope to Nightsters produced between December 6, 2021 and September 9, 2022—accounting for 1,074 units. However, Nightster models produced after September 9, 2022, don’t apply to this recall, as Harley employed “enhanced manufacturing controls” on those units. After informing the NHTSA, the firm notified its dealers of the impending recall on October 11, 2022. One week later, on October 18, 2022, the brand sent notification letters to impacted owners. Once eligible customers transport their Nightster to their local dealership, Harley will replace the faulty handlebars free of charge. While the notification period […]

Concept Motorcycle for the Moon: global debut at ADV Overland exhibition

General Posts / By

by Otilia Drăgan from https://www.autoevolution.com This Spectacular Moon Concept Motorcycle Opens the Door to a New Space Experience Since the “billionaire space race” has been accelerating, you might have imagined cosmonauts doing a lot of things, but we bet you didn’t picture them riding motorcycles on the moon. Yet, that’s what’s coming, because somebody just built an actual moon motorcycle, one of the most insane concept two-wheelers you’ll ever come across. Last year, a Russian designer imagined what a “NASA motorcycle” would look like. Just one year later, that concept turned into reality and is about to make its world debut in California. The folks who made this happen are a small team from a German company called Hookie, which specializes in custom moto design and parts. Inspired by Andrew Fabishevskiy’s fantasy motorcycle, they were determined to bring it to life. This is how Tardigrade, presented as the world’s first moon concept motorcycle, was born. You might wonder why it got the name of an apparently primitive creature, but these nearly-microscopic beings are incredibly resilient and able to adapt to any kind of environment, including outer space. Despite its otherworldly look, the Tardigrade motorcycle was also meant to be resilient and completely functional, “as close as possible to an original concept of a NASA moon rover.” This futuristic-looking electric motorcycle blends a lightweight frame with single-sided swing arms, balloon tires, and drive-by-wire steering. With a length of 8.5 feet (2.6 meters), and almost 3-foot (0.9 meters) tall, Tardigrade has a battery range of up to 68 miles (110 km). Its maximum speed of 9 mph (15 kph) is comparable to that of the Moon Buggy. Plus, it’s designed to also carry equipment. Incorporating 3D-printed parts, in house-developed wheels, plus a Cake drivetrain and sustainable lubricants from Puraglobe, this one-of-a-kind concept

What is Hub-center Steering Motorcycle & Why it is Better

General Posts / By

by Todd Halterman from https://www.autoevolution.com Hub-center steering is one of several different types of front-end suspension and steering mechanisms used in motorcycles and cargo bicycles. It is essentially a mechanism that uses steering pivot points inside the wheel hub rather than a geometry that places the wheel in a headstock like the traditional motorcycle layout. Perhaps the most venerable example of the idea came in the form of the 1930 Majestic. This Georges Roy design used a novel pressed-steel monocoque chassis, and it incorporated an automotive-type chassis with hub-center steering. Other bikes had already used the configuration in such machines as the Ner-A-Car and the Zenith Auto-Bi, but the Majestic made it lovely to behold. Another bike, the Vyrus 984 C3 2V Razzetto, was one such motorcycle that used hub-center geometry. Vyrus is a small Italian motorcycle manufacturer based in Coriano, Italy, and their bikes such as the “Tesi” – Thesis in Italian – had their designs originate from a university engineering project linked to the motorcycle legend Massimo Tamburini. The Tesi, and the Vyrus 984, were instantly identifiable by their use of their hub-center steering front suspension and steering arrangement. Those fabulously expensive bespoke motorcycles have been called “functional works of art,” and they look a bit like something you might see in a video game. In hub-centered bikes, the front wheel is attached to a swingarm with a shock and an internal pivot point. Steering is achieved using those linkages to turn the wheel on a pivot point. Hub-center steering has been employed on motorcycles for more than a century, but the design, despite what some engineers say offers a distinct advantage, never took hold. But the founder of Vyrus, Ascanio Rodorigo, once worked for Bimota as a race mechanic and engineer during the 1970s and his tenure

Salt Torpedo Action Update Chapter 16

General Posts / By

Making Move on Everything! The last few weeks have been interesting and challenging. We are actually getting close to watching the Salt Torpedo sit on its own three wheels with the help of Yelvington Shocks. This week we could finish the steering system. We could link the steering with the wheels. We could have a gas tank mounted. We are getting damn close to making a battery mount, and then hooking up the drive line for a run around the block.
