Yoshimura Honda CB1000F Cyclone Slip-On Preview

Yoshimura Japan’s retro can sheds 1.9 lb from $809

The Short Answer: The Yoshimura Honda CB1000F Cyclone Slip-On is a Yoshimura Japan Street Series motorcycle exhaust for the 2026 Honda CB1000F. It costs $809 with a stainless muffler or $859 with a titanium muffler, weighs 8.6 or 8.2 pounds versus 10.1 for stock, and adds up to 1.2 percent more horsepower. A $279 radiator Core Protector joins it.

Some motorcycles look like they were designed in a wind tunnel. Honda’s new CB1000F looks like it was designed in a mall arcade around 1982, and we mean that as a compliment. Yoshimura agrees. Its release says the bike will have you singing “I Love Rock ‘n’ Roll” and digging out your parachute pants, which is about the most Yoshimura press release opener we’ve ever read. To match the look, Yoshimura R&D of America is now selling Yoshimura Japan’s Cyclone Slip-On for the CB1000F, plus a radiator Core Protector that also fits the CB1000 Hornet.

What Is the Yoshimura CB1000F Cyclone Slip-On?

The Cyclone is a round-muffler slip-on from Yoshimura’s Street Series, engineered, developed and built by Yoshimura Japan. Yoshimura’s U.S. product pages list it in two versions:

• Cyclone Stainless Slip-On with Stainless Muffler (part #110-41L-5450): $809. Yoshimura’s release calls this the “polished stainless steel” version for the classic look, and its material code is SS/SS/SS.
• Cyclone Stainless Slip-On with Titanium Muffler (part #110-41L-5480): $859. The release calls this the “brushed titanium” Cyclone, and its material code is SS/TI/SS. In other words, it’s still a stainless slip-on, with a titanium muffler.

Both versions have a removable sound insert. Pull it out and the tone gets louder, which Yoshimura offers “if you’re looking to change the tone to something a little louder.” Yoshimura also says the system works with the center stand without modification. Nothing kills a fresh-exhaust buzz faster than a stand and a pipe that can’t share the same space.

Yoshimura’s fitment tab lists the 2025 and 2026 Honda CB1000F. Honda sells the CB1000F in the U.S. as a 2026 model, so for American riders the 2026 bike is the one that matters.

Performance: Power, Torque and Weight Claims

Yoshimura’s claims are modest, and we appreciate the honesty:

• Horsepower: Up to 1.2 percent more at 8,750 rpm.
• Torque: Up to 1.8 percent more at 4,000 rpm.
• Sound: A “deeper throatier tone,” measured at 93 dB at 4,500 rpm. Yoshimura doesn’t list the test standard or a stock figure for comparison.

For context, Honda’s U.S. site doesn’t publish a horsepower figure for the CB1000F. Honda Europe rates it at 91 kW (about 122 hp) at 9,000 rpm and 103 Nm (about 76 lb-ft) at 8,000 rpm. Yoshimura’s 1.2 percent comes at 8,750 rpm, right near that peak. Applied to a number in that range, it works out to roughly 1.5 hp. You won’t feel that in the seat of your pants, but you’ll hear the new tone every time you start the bike.

The torque gain shows up at 4,000 rpm, where most of us actually ride on the street, which suits an engine Honda tuned for low- and midrange pull.

Weight is where the Cyclone earns its keep:

• Stock muffler: 10.1 pounds
• Cyclone with stainless muffler: 8.6 pounds (1.5 pounds lighter, about 15 percent)
• Cyclone with titanium muffler: 8.2 pounds (1.9 pounds lighter, about 19 percent)

The titanium version costs $50 more and saves another 0.4 pound. That’s $125 per pound, which is still cheaper than most of the carbon fiber we’ve been tempted by over the years. Skipping dessert is free, but less fun.

Why the Cyclone Suits the CB1000F

Honda’s own pitch for the CB1000F leans on heritage. American Honda says it’s a modern take on the late-1970s CB750F and CB900F, with a “flow line” fuel tank and sidecovers, retro graphics and an upright riding position. The U.S. bike comes in Wolf Silver Metallic, the same silver-and-blue livery on the bike in Yoshimura’s photos.

A long, round, brushed or polished can suits that look far better than a stubby modern muffler. In Yoshimura’s photos of the titanium version on a Wolf Silver Metallic CB1000F, the bike looks more complete than it does stock.

Under the retro styling is serious hardware. Honda’s U.S. spec sheet lists a 1000cc liquid-cooled DOHC inline-four with 11.7:1 compression and 44mm throttle bodies, a six-speed gearbox and a #525 chain with 16/45 gearing. Honda says the engine uses the layout proven on the Hornet, tuned for more low- and midrange horsepower and torque. Honda Europe adds that the engine traces back to the 2017 CBR1000RR Fireblade. It also gets lower first and second gears than the Hornet, a fully adjustable 41mm Showa SFF-BP fork and radial-mount Nissin calipers on dual 12.2-inch (310mm) floating rotors. Curb weight is 472 pounds with a full 4.2-gallon tank.

Yoshimura Japan Radiator Core Protector

The second item in the release is Yoshimura Japan’s Radiator Core Protector (part #454-41L-0000, $279). Yoshimura lists it for the 2025 and 2026 CB1000F and CB1000 Hornet, and the description also names the CB1000F SE. Here’s how Yoshimura describes it:

• Material: 0.8mm (about 0.03-inch) thick 304 stainless steel with a fine brushed pattern for a semi-matte finish.
• Construction: Made with a highly accurate etching process. The product page says the 3-into-1 hexagonal pattern is inspired by the “Y” in Yoshimura.
• Design: The center section has a smaller open area for more protection, because that’s where debris kicked up by the front tire hits. The sides are more open for maximum airflow and cooling.

Anyone who has picked a rock out of a radiator, or paid to replace one, knows $279 is cheap insurance. Yoshimura’s photo shows the guard on the CB1000F with the brand’s logo etched into the mesh, so it’s also a bit of quiet branding.

Hornet SP owners should confirm fitment with Yoshimura, since the product page lists the “CB1000 Hornet” but doesn’t name the SP separately.

Price, Availability and Warranty

Yoshimura’s release and its U.S. product pages agree on price: $809 for the Cyclone with the stainless muffler, $859 with the titanium muffler and $279 for the Radiator Core Protector. Go all in with the titanium Cyclone and the Core Protector and you’re at $1,138, or a little over 10 percent of the CB1000F’s $10,599 base MSRP. Honda adds a $775 destination charge to the bike.

The release doesn’t give an on-sale date. When we checked, Yoshimura’s site listed both Cyclone versions as sold out with a “Contact Us for Availability” note and the phone number 1-800-634-9166. The Core Protector is a special-order Yoshimura Japan item, and Yoshimura says in-stock Japan items take 17 to 24 days to deliver. If you want one for spring, order early.

Yoshimura R&D of America covers its exhaust systems with a limited one-year warranty against defects in workmanship and/or materials for the original purchaser. The Core Protector’s product page shows the same one-year badge.

On the legal side, Yoshimura’s Cyclone product pages list an emissions compliance declaration of Qualified Manufacturer Declared “Replacement Part.” Yoshimura says its Street Series slip-ons don’t require tampering with the bike’s emissions controls and offer “street-legal options.” The product pages don’t mention a California Air Resources Board (CARB) Executive Order number, so California riders should confirm with Yoshimura before ordering.

How Does It Compare With Yoshimura’s U.S.-Made Pipes?

The Cyclone is a Yoshimura Japan product, and its product pages show a Made in Japan badge. Yoshimura’s AT2 line comes out of Chino, California. We’ve run that pipe on a few bikes. Our 2026 Honda CB1000 Hornet SP Road Test bike wore an AT2 slip-on, and we rode it out to Yoshimura’s headquarters in Chino. The same bike, same pipe, also appears in our 2026 Honda CB1000 Hornet SP Real MC Commute. Since the CB1000F uses the Hornet’s engine architecture, those reviews are the closest look at what’s under the CB1000F’s retro tank.

For a closer look at how Yoshimura’s slip-ons perform, see our Yoshimura AT2 Exhaust Review on the Kawasaki Ninja ZX-6R and our recent Yoshimura MT-09 AT2 Speed Series Full System Preview. If you want the backstory, our Yoshimura R&D Tour and Honda CRF300L Rally RS-12 Exhaust Install walks through the company’s Chino headquarters and its racing history.

The Bottom Line

The Yoshimura Honda CB1000F Cyclone Slip-On doesn’t promise big power, and it doesn’t need to. It cuts 1.5 to 1.9 pounds, adds a deeper tone with a removable insert for more volume, works with the center stand and gives Honda’s retro roadster a round can that suits its 1982 look. At $809 or $859, it’s a sensible first mod, and the $279 Core Protector is cheap radiator insurance. Parachute pants sold separately.
