Harley-Davidson CVO Road Skim And Street Float Audit

In terms of volume and type, the biggest competitor of Harley-Davidson is himself in the used market. Since 2000, Harley-Davidson has sold more than 2 million touring models. These are their Street Glide, Road Glide, Ultra and similar motorcycles, not cruisers like the Softail Fat Boy or old Dynas, which were also sold in similar numbers during the same period. The now-discontinued air-cooled Sportster sold almost 1.2 million units during this period. The Harley-Davidson motorcycle deliveries published by Harley-Davidson from 2000 to 2022 amount to a total of 5,808,881 units.

Therefore, it is extremely important to keep the Grand American Touring line (Harley’s official name for the platform) attractive—more attractive than last year’s Road Glide and the rest.For this reason, Harley-Davidson introduced the CVO Road Glide and the CVO Street Glide 2023 with extensive changes to the traditional 45-degree V-Twin, improved suspension, new infotainment and a heavily revised design.

Every crease, contour and edge of the reworked fairings is new, and yet the world knows exactly which motorcycles you are looking at.

CVT CVO 121 Engine
When the new engine starts, the world also knows exactly what it is hearing. Well, you will recognize the potato-potato sound as a 45-degree V-twin, but please note the “VVT” on the side of this 121ci Milwaukee-Eight engine. After all, a Large twin finally has a variable valve timing.The VVT moves the single cam with higher lift and longer service life by 40 degrees of adjustment (relative to the crankshaft), smoothes and increases the power over the entire speed range. VVT can be more efficient by working on separate inlet and outlet cams to control the overlap (when they are reduced to low revs, idling is compensated and emissions are reduced if you increase power at high revs), but since Harley-Davidson cams are usually turned to torque and use less overlap than an average Ducati, working on a single cam where the relative position of the inlet and outlet valves is fixed is not a big problem.

The VVT works with a larger 4-liter airbox, which feeds a 58 mm throttle body (instead of 55 mm) and straighter, more fluid openings for the four-valve heads. The valve seats and the combustion chamber are redesigned, with the former providing better flow and the latter more squish and improved combustion. Changes to the combustion chamber and the revised strategic liquid cooling made it possible to significantly increase the compression from 10.2:1 to 11.4:1 compared to 117.The piston diameter is the same as the Big Twin 117ci at 4.075 inches, but a very long stroke of 4.625 inches helps this 1,977 cm3 engine to produce 139 .- checked. Torque at 3,000 rpm and 115 hp at 4,500 rpm. This compares favorably to the claimed figures of the 103-horsepower non-VVT 117 at 4,750 and 126 .- checked. at 3,500. For reference, the most recent breakout 117 we used for the dyno was 118 .- checked. and 94 hp on the rear wheel (the measured rwhp is usually about 7 to 15 percent below the values declared by each factory). The claimed peak power increases for both the power and torque tracks with the increase of the displacement by about 4% between 117 and 121, but the larger engine feels like it has more space under these curves, which means a wider power distribution. We will be driving the 121 VVT and will receive the rear wheel numbers as soon as a test motorcycle is available. Harley-Davidson also claims a potential increase in fuel consumption by 3 to 5 percent.
