Honda CB300R Top Speed, 0-60 Time & Specs Review
TL;DR
- Honda CB300R top speed lands around 97-98 mph, based on GPS-tested data from its fully faired sibling, which shares the same 286cc engine.
- 0-60 mph takes roughly 6.1 to 6.4 seconds, depending on whether you’re looking at real-world testing or a formula-derived estimate.
- The engine makes a claimed 31 hp at the crank and about 27.6 hp at the rear wheel.
- 2026 MSRP is $4,499, a price cut from the 2025 model’s $5,149.
- Curb weight is 316 lb wet with a 31.6-inch seat height, making it one of the easier naked bikes to handle at a stoplight.

How Fast Is the Honda CB300R’s Top Speed?
The Honda CB300R tops out around 97-98 mph in real-world conditions. Honda doesn’t publish an official top speed figure for the US market CB300R, so the most reliable number comes from GPS-instrumented testing of the CBR300R, its fully faired sibling that shares the identical 286cc single-cylinder engine (MotoStatz, 2026).
That GPS test clocked the CBR300R at 97.85 mph, with the note that top speed on a small-displacement single is heavily affected by rider size, weight, and wind. A taller, heavier rider tucked in less aggressively will see a lower number.
Owner reports on rider forums put the naked CB300R in a similar 93-98 mph range, which lines up with the physics: less bodywork than the CBR means slightly more drag, so real-world top speed for the naked CB300R likely sits at the low end of that band rather than the high end.
This isn’t a bike built to chase a top speed number anyway. It’s a commuter and backroads bike first. Honda’s own testing shows the CB300R holds 75-80 mph on the highway without drama, which is what actually matters for daily riding.
What’s the CB300R’s 0-60 Time?
The CB300R’s 0-60 mph time runs somewhere between 6.1 and 6.4 seconds, depending on the source and testing method. There’s no independent GPS-instrumented 0-60 test specific to the naked CB300R yet, so this figure is built from the closest available data.
The CBR300R, using the identical engine, ran 0-60 in 6.36 seconds under that same GPS test, with a quarter mile of 15.14 seconds at 85 mph. Separately, a formula-derived estimate model puts the CB300R at 6.1 seconds to 60 mph, based on power-to-weight calculations rather than an actual timed run (ProfessCars, 2019). Treat that second figure as a rough estimate, not a tested result.
For a 286cc single making 27-28 hp at the wheel, mid-6-second 0-60 times are about what the numbers predict. It’s brisk enough to keep up with city traffic and merge onto the highway without straining, but riders coming from a 600cc-plus bike will notice the difference immediately.
How Much Horsepower Does the CB300R Make?
The CB300R makes a claimed 31 hp at the crank and roughly 27.6 hp at the rear wheel. Honda doesn’t officially publish rear-wheel dyno figures for the CB300R, but a Honda representative confirmed the crank number, and the closest dyno data comes from the CBR300R’s identical engine, which measured 27.6 hp at the rear wheel in prior testing (Rider Magazine, 2019).
Torque peaks at 20.3 lb-ft around 7,500 rpm on the claimed figures, which is modest but comes on early enough to feel punchy off the line in city riding. A separate dyno comparison against the KTM 390 Duke measured the same engine at 27.5 hp and about 18.7 lb-ft at the rear wheel, a second data point that lands close to the figure above.
None of these are huge numbers, and that’s the point. This is an entry-level single built for new riders and commuters, not a bike chasing spec-sheet bragging rights against 400cc twins.
How Does the CB300R Handle in the Real World?
The CB300R handles like a bike built around its light weight, not its horsepower. At 316 lb wet with a 53.2-inch wheelbase, it turns in quickly and holds a line through backroads without fighting the rider.
The 41mm Showa SFF-BP inverted fork up front isn’t adjustable, but it’s compliant enough for daily riding and doesn’t feel out of place on a bike this size. The rear Pro-Link shock offers 7-step preload adjustment, which is enough to dial in for a solo rider or add a passenger without the back end wallowing.
A 31.6-inch seat height is on the taller side for the beginner category, something shorter riders should sit on before buying. Braking comes from a single 296mm front disc with a radially-mounted 4-piston caliper and standard ABS, plenty for a bike in this weight and power class.
Is the Honda CB300R Worth the Price in 2026?
At $4,499 for 2026, the CB300R is one of the more affordable naked bikes Honda sells in the US, and that price is actually a cut from the 2025 model’s $5,149 MSRP (Rider Magazine, 2025). For that money, riders get standard ABS, a slip/assist clutch, and styling borrowed from the larger CB1000R.
The trade-off is straightforward: less power than rivals like the KTM 390 Duke or Kawasaki Ninja 400, but a lower price, lighter weight, and Honda’s reputation for reliability. New riders and commuters looking for a first bike or a low-stress daily ride are the clear target, while riders wanting more highway passing power should look at the CB500 Hornet or a 400cc-plus alternative instead.
