Honda · Standard

The Honda CB300R is a lightweight naked bike with a 286cc liquid-cooled single, a six-speed gearbox, an inverted Showa fork and standard ABS. It uses the same engine as the Rebel 300 and CBR300R. It suits a first-time or returning rider who wants a light, easy commuter with sportbike-grade suspension parts, and it gives up power to the KTM 390 Duke.

What the CB300R is like to ride

The CB300R is built around a light chassis and a friendly engine. Rider Magazine highlights the 316 lb weight and the 31.6 in seat as a reasonably short reach to the ground, and called the thin-looking seat deceptively comfortable. The front end uses 41mm Showa SFF-BP inverted forks, which Total Motorcycle credits with bump absorption and front-end feel.

The brakes and wheels are tuned to keep unsprung weight down.

Rider Magazine's tester weighed 110 lb and found the standard rear setup a bit stiff, but heard from heavier riders that the rear feels too soft. If you weigh well over 180 lb, sit on one first or plan to adjust the preload.

Fuel range and everyday living with the CB300R

The CB300R sips fuel from a small tank. Rider Magazine averaged 73.5 mpg, and although the 2.6 gal tank gives a total range of about 190 miles, the fuel light came on at around 130 miles, so plan stops before then. The short 53.2 in wheelbase gives quick steering that falls into turns with little input, which the same review says makes navigating tight alleys a breeze.

The article calls the CB300R a great commuter that is even more fun on winding back roads.

CB300R against the 390 Duke and MT-03

Yamaha's MT-03 is the other natural rival: a 321cc twin at $4,999 that weighs 373 lb against the CB300R's 316 lb. The Honda is the lightest and cheapest of the three, and the Yamaha and the KTM offer more engine.

2026 Honda CB300R questions

Is the Honda CB300R a good beginner motorcycle?

Yes. It weighs 316 lb, the seat is 31.6 in high, ABS is standard, and the 286cc single makes its power smoothly. It shares its engine with the Rebel 300 and CBR300R.

Does the CB300R share an engine with other Hondas?

Yes. Rider Magazine notes it uses the same liquid-cooled 286cc single as the Rebel 300 and the fully faired CBR300R, so parts and tuning knowledge carry across the three models.

The KTM 390 Duke is the CB300R's performance-minded rival. The comparison is power for price. A MatthewBikeLog comparison lists the 390 Duke's 373cc single at 43 hp and 35 Nm against the CB300R's 286cc single at 30 hp and 27 Nm, with the KTM adding a fuller electronics package and adjustable suspension. The Honda is the smoother, simpler bike to live with. The KTM is the one to buy for spirited riding.

One ownership note: reaching the battery means removing the fuel-tank cover and the seat, and even then lifting the real fuel tank. So a jump-start is easier than a battery change. Total Motorcycle lists the LCD display with a gear-position indicator, radial-mounted front brakes, and an assist and slipper clutch that eases upshifts and reduces rear-wheel hop under hard braking and rapid downshifts.
