Screamin’ Eagle 135ci Stage IV Crate Engine

by Dustin Wheelen from https://www.rideapart.com The Milwaukee-Eight V-Twin produces 143 lb-ft of torque and 130 horsepower. Tens of millions of dollars and countless man-hours go into Harley-Davidson’s King of the Baggers operation. None of those resources go to waste, either, with the Motor Company snatching the KotB crown in 2021 and nearly repeating in 2022. The fruits of the race team’s labor go beyond the circuit as well, with H-D engineers and designers fashioning race-developed parts for brand faithful. Now, Harley brings even more KotB-proven performance to the market with its Screamin’ Eagle 135ci Stage IV crate engine. The new top-dog Milwaukee-Eight V-twin features the same 68mm throttle body and CNC-machined intake manifold originally designed for Kyle and Travis Wyman’s championship-contending Road Glide Special. Screamin’ Eagle Extreme CNC-ported cylinder heads, high-performance valve spring, and an SE8-517 high-lift camshaft take full advantage of the V-twin’s larger 2,212cc volume. Forged pistons shoot through 4.31-inch steel-sleeve cylinders with 4.625 inches of stroke. The 4 5/8-inch flywheel steadies the big-bore M8, while the Screamin’ Eagle Pro Billet Cam Plate and Oil Pump maintain optimal oil pressure. With a 10.7:1 compression ratio and high-flow fuel injectors (6.8 grams/second), the 135 crate engine lays down 143 lb-ft of torque (at 3,500 rpm) and 130 horsepower (at 5500 rpm)—all at the rear wheel. That output eclipses the Bar and Shield’s largest production engine, the Milwaukee-Eight 117, by 28 percent in the torque department and 41 percent in pony power. Harley-Davidson recommends pairing the Stage IV Milwaukee-Eight with Screamin’ Eagle Ventilator Extreme Air Cleaner and Screamin’ Eagle Street Cannon mufflers to achieve those reported power figures. Retailing for $7,999.95, the Screamin’ Eagle 135ci Stage IV Performance Crate Engine comes in a Black or Chrome finish and is compatible with 2021 and later Touring models (sans Trikes).

Vance & Hines Expands New PCX Lineup

Vance & Hines Expands New PCX Lineup with Return of the Pro Pipe and Debut of Bagger Race Replica System Santa Fe Springs CA – Vance & Hines, which earlier this week announced its innovative new PCX (Power Chamber Exhaust) technology, is now adding two new 2-into-1 exhaust systems to their product line. The introduction includes the return of the ultra-popular Pro Pipe 2-into-1 exhaust system and a system inspired by the one used on the company’s King of the Baggers racers, a series that has inspired a new level of custom and performance in Harley-Davidson touring bikes. PCX technology ensures that these Vance & Hines systems meet all EPA emissions criteria. Pro Pipe is a classic design that has twenty years of evolution and improvement built into its return to market. It has all the ingredients for making power: stepped headers, an oversized collector and long megaphone muffler. The new generation Pro Pipe now features the innovative PCX™ technology, which integrates a chambered high-flow catalyst in the megaphone for a bigger boost in torque and a more robust rumble of a big V-Twin motor. The placement of the catalyst deeper into the muffler moves heat away from the rider and improves rider comfort. The Pro Pipe system fits Harley-Davidson Milwaukee-Eight Touring (2017-2022) and Softail (2018-2022) models, as well as late model Twin Cam Touring models (2010-2016). The Vance & Hines Hi-Output RR exhaust system comes directly out of the development work done for the riders in the King of the Baggers class of the MotoAmerica Road Racing Championships. Constructed of high grade, 304 stainless steel, the hand TIG welded headers of the Hi-Output RR step from 1.75″ to 1.875″ to 2.0″ and feed into the same oversized collector used on the race exhaust system. The collector is even rotated

Travis Wyman will race a factory-prepared Harley-Davidson Road Glide® Special powered by a modified Screamin’ Eagle® Milwaukee-Eight 131 Performance Crate Engine. He joins his brother, Kyle Wyman, on the two-rider team for the King of the Baggers race June 11-13 at Road America near Elkhart Lake, Wis. In addition to its factory team effort, Harley-Davidson is offering a nearly $30,000 cash contingency program for qualified Harley-Davidson® racers competing in the King of the Baggers series. “We are ready to turn up the heat in MotoAmerica at our home track of Road America by adding Travis to the Screamin’ Eagle factory team,” said Jochen Zeitz, chairman, president, and CEO Harley-Davidson. “The King of the Baggers series is bringing big excitement for fans and we’re pleased to add to the show by expanding our team to two top riders representing Harley-Davidson and Screamin’ Eagle.” The three-round MotoAmerica King of the Baggers series is for race-prepared, American V-Twin touring motorcycles equipped with a fairing and saddlebags.

Travis Wyman is the owner of Travis Wyman Racing, based in Las Vegas. He is currently also competing in MotoAmerica Stock 1000, Honos Superbike and Superbike Cup.

Harley-Davidson Milwaukee Eight Gets Bigger and Meaner

by Daniel Patrascu from https://www.autoevolution.com Harley-Davidson Milwaukee Eight Gets Bigger and Meaner with New 131 S&S Kit Do you know that saying “there’s no replacement for displacement?” It applies to all types of internal combustion engines, fitted on both cars or motorcycles, and has been the driving force behind many stunning machines over the years. In the motorcycle world, Harley’s Milwaukee Eight engine is one of the most famous powerplants. Part of the big twin family that has been around for eight decades, it was introduced in 2016 with a total of eight valves – four for each cylinder – hence the name. Generally, these engines come in three displacement options, namely 107, 114, and 117 ci. There’s an even bigger variant on the market, the Screamin’ Eagle Milwaukee Eight 131, “the biggest, most powerful street-compliant engine Harley-Davidson has ever created,” but this one is offered as a crate solution. Those looking to get more cubic inches and more power have several solutions at their disposal. The latest comes from S&S and is designed for Milwaukee Eights fitted on bikes from 2017 to the present day. Comprising upgrades like a new-design forged piston and 4.25-inch cylinders, the kit can take engines all the way to 131 ci (2.1 liters), but only when paired with the company’s stroker crank – we’re told the upgrade works with stock crankcases as well. According to S&S, the stock engine height remains after the kit is fitted, and so do the original serial numbers. There are three variants of the kit available, namely Wrinkle Black with highlighted fins, Wrinkle Black with non-highlighted fins, and Black Granite with highlighted fins. Regardless of the version, the price is $1,299.95, but that increases to $1,529.95 when opting for the stroker crank as well. Still, that should be peanuts

Harley-Davidson ELECTRA GLIDE STANDARD delivers an elemental Touring experience powered by the Milwaukee-Eight engine MILWAUKEE (Mar. 4, 2019) –Powered by the muscular Milwaukee-Eight™ 107 engine, the new Electra Glide Standard is a “Dressed down Dresser” that provides a raw, fundamental riding experience inspired by Harley-Davidson’s Grand American Touring roots. Designed for the traditional touring customer, the Electra Glide Standard is for the rider seeking to disconnect from all the noise of the day-to-day through riding.

The Electra Glide Standard features essential Harley-Davidson styling elements such as the iconic batwing fairing, chrome trim, standard saddle bags, and cast aluminum wheels. Chrome accents are added in high-impact design areas and complemented by polished rocker, cam and derby covers and select blacked out components – a blend of traditional elements and modern trends. “To express the stripped-back essence of the Electra Glide Standard we focused on finishes that were simple, timeless, and fundamental to the Harley-Davidson’s touring line. Chrome was added to key components and complimented by polished and blacked out parts, said Harley-Davidson’s Vice President of Styling & Design Brad Richards. “The rocker, cam, and derby covers are finished with chrome to emphasize the V-Twin shape of the Milwaukee-Eight 107 engine. In addition, they add a dose of nostalgia that draws a through-line all the way back to the first Electra Glide.” To provide a raw touring motorcycle experience without riding compromises, the Electra Glide Standard features all the latest ride and handling technology of Harley-Davidson’s Touring line such as standard electronic cruise control, hand-adjustable emulsion-technology rear shock absorbers, 49mm front forks with Showa dual bending valve suspension, and Brembo brakes
