Delivery and Deliverance

A tale of two parties to a deal and one steadfast old iron engine Text and photos by Ujjwal Dey with illustrations from Wayfarer An Enfield Bullet 350 finds a home after being in limbo for four stressful months. The cast iron engine with right-hand-side gear shift is a well-known legend among motorcyclists, especially purists who don’t want the brand name “Bullet” associated with run-of-mill modern designs & engines. What misadventure occurred and what new adventures await? “First time in life I decided to purchase a used vehicle. An out of production cast-iron engine Enfield Bullet 350cc with right-hand-side gear shift which is the closest thing available to the 1955 Enfield Bullet 350 including chassis and engine design by the Britishers among other things such as dashboard, tank, hand-painted pinstripe, etc. These come with Green Tax for the alleged pollution they may or might be making. I got a fitness test certificate from the Road Transport office, where the ownership change is registered.” — Dey Click here to read this awesome anecdote about ‘love after love’.

Ride Review: Harley-Davidson Touring ST Models for 2022

by Dustin Wheelen from https://www.rideapart.com/ Balancing the raceway and the roadway. Automotive and motorcycle dealers popularized the term “Win on Sunday, Sell on Monday” in the 1960s. While both motorsport and vehicle sales tactics have evolved over the decades, most manufacturers still leverage on-track supremacy for showroom success—including Harley-Davidson. From the hillclimb to the drag strip, from board tracking to flat tracking, racing has been in the Motor Company’s DNA since Walter Davidson won the 1908 Endurance and Reliability Run. However, Harley’s Post-War production lineup made the brand synonymous with cross-country tourers in the latter half of the 20th century. Despite the XR750 becoming the winningest motorcycle in AMA (American Motorcycle Association) history and the company’s countless NHRA drag racing titles, the FL Touring platform remains the Bar and Shield’s top seller. When MotoAmerica introduced the King of the Baggers (KotB) Invitational in 2020, the one-off race merged Harley’s flagship tourers with its racing lineage. Unfortunately, the MoCo’s first outing fell short of the top step, but the Screamin’ Eagle Harley-Davidson team seized the 2021 KotB championship with Kyle Wyman in the saddle. H-D is wasting no time—or development dollar—following that title run, equipping the 2022 Street Glide ST and Road Glide ST with track-worthy components. To test just how much race-bred technology has trickled down to its production models, the Motor Company invited us to Wilcox, Arizona to spin some laps around the inimitable Inde Motorsports Ranch. Harley certainly handled business on Sundays this previous season, and with the new ST range, it hopes to also dominate the competition on dealership floors. Turning A Corner With the U.S.’s interstate system crossing vast expanses of land, the Street Glide and Road Glide families prioritize comfort and convenience. Packing a six-gallon fuel tank, sub-27-inch seat heights, and a 64-inch wheelbase, the

Motorcycle Vibrations Can Damage iPhone cameras as per Apple

by Kim Lyons from https://www.theverge.com by Edward Moyer from https://www.cnet.com From Apple: https://support.apple.com/en-us/HT212803 Motorcycle vibrations can degrade iPhone camera performance, Apple says High amplitude vibrations can cause problems for the cameras’ gyroscopes A new post on Apple’s Support forum https://support.apple.com/en-us/HT212803 says exposing iPhones to high-amplitude vibrations, “specifically those generated by high-power motorcycle engines” could degrade the devices’ camera system. The company recommends against mounting an iPhone on a motorcycle, as the vibrations may be transmitted via the bike’s handlebars and chassis. Here’s the technical explanation from Apple: If you accidentally move a camera when you take a picture, the resulting image can be blurry. To prevent this, some iPhone models have optical image stabilization (OIS).1 OIS lets you take sharp photos even if you accidentally move the camera. With OIS, a gyroscope senses that the camera moved. To reduce image motion, and the resulting blur, the lens moves according to the angle of the gyroscope. Additionally, some iPhone models have closed-loop autofocus (AF).2 Closed-loop AF resists the effects of gravity and vibration to preserve sharp focus in stills, videos, and panoramas. With closed-loop AF, on-board magnetic sensors measure gravity and vibration effects and determine the lens position so that the compensating motion can be set accurately. The OIS and closed-loop AF systems in iPhone are designed for durability. However, as is the case with many consumer electronics that include systems like OIS, long-term direct exposure to high-amplitude vibrations within certain frequency ranges may degrade the performance of these systems and lead to reduced image quality for photos and videos. It is recommended to avoid exposing your iPhone to extended high-amplitude vibrations. The iPhone 6s, iPhone 6s Plus, and all iPhones since the iPhone 7 have both optical image stabilization and closed-loop autofocus (as noted by MacRumors, the first outlet to
