Pure thrill, every turn
Compact engine
The compact single-cylinder engine is a jewel with a free-revving, responsive nature. It works extraordinarily well in real-world road-riding conditions, providing plenty of power around town and on the highway.
Light, strong chassis
Great handling starts with a superior chassis, so we use a special light and strong frame construction. This gives the lightweight naked bike the perfect combination of nimble handling and athletic comfort.
Café style
Taking its styling cues from our CB1000R, the CB300R offers a fresh, contemporary take on the modern streetbike with its angular lines and minimalist design.
Standard ABS
Standard ABS helps you make controlled stops in less-than-ideal conditions, such as wet pavement, providing added confidence whether riding for fun or commuting.
Rise above the ordinary
Underslung exhaust
An underslung exhaust features a dual-chamber design with a right-side exit. The high-flow system contributes to the bike’s ultra-linear throttle response.
Fine-tuned intake and exhaust
The engine’s intake and exhaust are designed to reduce air resistance, contributing to more linear power delivery and increased throttle response.
Inverted front fork
The inverted fork provides a smooth ride with compliant damping, featuring a supple spring rate just right for a bike of this size.
Lightweight construction
At over 30 pounds lighter than our previous CB300F generation, the 2025 CB300R’s user-friendly curb weight means this bike handles well and is easier to balance at stoplights or parking lots.
Lightweight aluminum wheels
Unsprung weight—tires, wheels, and brakes—is critical to a bike’s responsive handling. That's why we gave it lightweight aluminum wheels. Plus, they just plain look cool, too.
Perfect balance
A perfect 50/50 weight balance front-to-rear provides unmatched sport riding, combining rear-wheel traction, front-end grip, and equally balanced braking forces.
Tapered rubber-mounted aluminum handlebar
A premium tapered handlebar with a larger diameter clamped area delivers a direct connection to the bike and excellent steering feedback.
Passenger ready
A separate passenger seat, integrated grab rail, and passenger footpegs allow you to take a friend along for the ride—another example of the bike’s versatility.
Comfortable riding position
The seat height and position give the lightweight streetfighter an engaged, athletic riding position. This upright view lets you easily see what’s happening around you, making it easy to instantly respond to the road.
All-LED lighting
An all-LED lighting package is another example of the bike’s modern approach. The round headlight with LED blubs nods to classic naked bikes with today’s tech, while the super-thin LED taillight provides a clean, low-profile look.
LCD instruments
A lightweight, full-function LCD display adds a premium feel. It’s 60 percent thinner than previous generations and provides easy-to-read displays for engine rpm, speed, gear position, and more.
