The inline-four engine, once a staple in mid-size motorcycles, is rapidly disappearing. Manufacturers are favoring simpler, cheaper parallel-twin designs. But for enthusiasts who crave the smoothness and high-revving character of an inline-four, options are dwindling. As of 2026, the Honda CB650R E-Clutch stands as the most affordable new inline-four motorcycle on the market.
The Decline of the Inline-Four
The inline-four’s popularity peaked in the 1980s and 90s, with models like the Honda CB750 setting the standard. These engines delivered a thrilling, turbine-like experience. However, they are inherently more complex and expensive to produce than single- or twin-cylinder alternatives. Modern regulations further discourage them, as stricter emission and noise standards make four-cylinder designs less desirable.
Despite this trend, a few manufacturers continue to cater to purists. Kawasaki’s Ninja ZX-4R and the upcoming Honda CBR500R Four remain in production. But the CB650R E-Clutch now holds the price advantage.
Why the CB650R is the Cheapest
For a while, Kawasaki’s ZX-4R was the most affordable option. But Honda’s recent price cuts and Kawasaki’s price increases have shifted the balance. The CB650R E-Clutch starts at $8,699, undercutting the CBR650R E-Clutch by $100 and beating the older Suzuki GSX-S750 by $150. The Suzuki is dated, having not been updated since 2022, making the CB650R a superior package.
Engine and Performance
The CB650R is powered by a liquid-cooled 649 cc inline-four. Its oversquare configuration (67 mm bore, 46 mm stroke) and DOHC valve operation deliver high-RPM performance. The engine produces 94 horsepower at 12,000 rpm and 47 pound-feet of torque at 9,500 rpm.
The bike features a six-speed manual transmission with a slip-assist clutch. Honda’s new E-Clutch system allows clutchless shifting, but can be disabled for traditional operation.
Chassis and Components
The CB650R weighs 456 pounds, thanks to its steel diamond frame, which uses the engine as a stressed member. Suspension includes 41 mm inverted Showa SFF-BP forks with 4.7 inches of travel and a Showa monoshock with adjustable preload.
Braking is handled by dual 310 mm front discs with radial-mount Nissin calipers and a 240 mm rear disc, all equipped with dual-channel ABS. Lightweight 17-inch cast aluminum wheels complete the package.
Technology and Styling
The CB650R includes a 5-inch TFT instrument cluster with RoadSync smartphone connectivity and three display modes. Safety features include Honda Selectable Traction Control and emergency brake lights.
Stylistically, the bike follows Honda’s neo-sports café design language, featuring a round LED headlight and a minimalist, muscular look.
The CB650R E-Clutch is a compelling option for riders who want the experience of an inline-four without breaking the bank. It combines performance, modern technology, and classic styling at a price point that makes it the last affordable choice in a shrinking market segment.
