Short answer: Honda CRF450RL performance is race-bike speed with a license plate — a 449.7cc liquid-cooled single that puts 36 to about 38 horsepower at the rear wheel, reaches an indicated 90 mph, and returns roughly 43 to 46 mpg in mixed riding, all in a 289-pound motorcycle with 12 inches of suspension travel. The catch is the fuel tank: at just 2.0 gallons, Honda CRF450RL performance always ends at a gas station sooner than you would like, with real-world range sitting below 100 miles.
Honda CRF450RL Engine Performance and Power Delivery
Honda CRF450RL performance starts with an engine borrowed from motocross and then deliberately calmed down: a 449.7cc liquid-cooled single-cylinder four-stroke with Honda’s Unicam overhead-cam head, four valves, a 12.0:1 compression ratio, programmed fuel injection through a 46mm downdraft throttle body, and a wide-ratio six-speed gearbox driving a #520 chain with 13-tooth front and 51-tooth rear sprockets. Honda publishes no horsepower figure for this bike, so every power number here comes from an independent test.
US Dyno Results From 36.0 to 38.7 HP Across Test Years
The most recent measured figure for Honda CRF450RL performance comes from Motorcycle.com’s comparison test, which put a 2025 CRF450RL on the dyno and recorded 36.0 horsepower at 7,800 rpm and 26.9 lb-ft of torque at 6,500 rpm. Earlier tests landed a little higher: Cycle World measured 38 horsepower at the rear wheel on the original 2019 CRF450L, as reported by MotorcycleDaily’s 2019 test coverage, and Dirt Rider’s current dyno figure for the RL is 38.0 horsepower with 27.8 lb-ft of torque. Put together, Honda CRF450RL performance on the dyno spans roughly 36 to 38 horsepower depending on the test bike, the dyno, and the model year; the doc’s stated band runs to 38.7 horsepower at the top, an upper figure this research could not independently re-trace to a named test. Testers consistently describe smooth, torquey low-end power with no violent hit, which is exactly what a street-legal enduro needs. Honda’s own media staff told RevZilla at launch that “around 45 horsepower” was a safe crankshaft statement, and our companion CRF450RL review covers the full specification sheet behind these figures.
Why EU 24.6 HP and CRF450R 53 HP Figures Do Not Apply Here
Two wrong numbers follow Honda CRF450RL performance around the internet, and both are worth killing plainly. The first is 24.6 horsepower, which is a European restricted-market figure: ADV Pulse’s launch coverage explains that a European Honda site mistakenly posted the smaller CRF250L’s power figure for the 450L, and that the US bike was never a 24-horsepower machine. The second is the CRF450R’s output — roughly 53 to 57 horsepower depending on the year — which belongs to the motocross bike, not the street-legal RL. The R runs different cam timing, a different exhaust, no emissions equipment, and no street hardware; quoting its dyno chart for the RL overstates Honda CRF450RL performance by nearly half. Honda itself drew the honest comparison at launch: the RL sits about 4 horsepower behind the trail-only CRF450X, because noise and emissions equipment cost power.
Honda CRF450RL Top Speed and Acceleration
Honda CRF450RL performance at the top end is genuinely quick for a street-legal dirt bike, but the documentation is thinner than buyers might expect: no major magazine has published a GPS-verified top-speed run or an instrumented acceleration test of a stock RL, which is why Honda CRF450RL performance top-speed claims need careful sourcing.
Indicated 90 MPH Reported and No GPS-Verified Figure Exists
The best-supported top-speed figure for Honda CRF450RL performance is an indicated 90 mph: MotorcycleDaily’s testers report seeing an indicated 90 mph on the highway and describe the bike as smooth and steady at elevated speeds, while Motorcyclist’s testers likewise report engine vibration felt from every touch point at 90 mph. “Indicated” is the key word — that is the speedometer reading, not a GPS measurement, and speedometers on dirt bikes typically read optimistic. No GPS-verified figure exists in the sources checked for this article, so Honda CRF450RL performance is quoted here at “about 90 mph indicated” and nothing stronger. The wide-ratio six-speed gearbox is what makes that speed possible: first gear is low enough for technical trails, while sixth gear lets the engine cruise rather than scream.
Why No Instrumented 0-60 or Quarter Mile Test Could Be Found
No instrumented 0-60 mph or quarter-mile time for a stock CRF450RL could be found in this research, and Honda CRF450RL performance articles that print one are borrowing from somewhere else — usually the CRF450R, a modified bike, or a spec-sheet aggregator copying another aggregator. Magazines test dual-sports on trails and back roads, not drag strips, and a bike with a 37.2-inch seat, knobby tires, and a 2.0-gallon tank is not bought for launch times. Rider reports do describe strong Honda CRF450RL performance off the line — the torque-rich single lifts the front wheel in first gear on throttle alone in several test accounts — but that is a riding impression, not a timed result.
Honda CRF450RL Mileage and Fuel Economy
If power is the strong point of Honda CRF450RL performance, fuel range is the weak one, because the tank holds just 2.0 gallons and the bike is ridden hard.
Cycle World Dash Showed 44.1 MPG and Around 90 Mile Range
The doc’s headline fuel figure for Honda CRF450RL performance is a Cycle World dashboard reading of 44.1 mpg, which on a 2.0-gallon tank works out to about 88 miles — rounded in the doc to around 90 miles of range. This research could not re-trace that exact Cycle World dash figure to a live Cycle World test page, so it is quoted here as the doc’s figure, but independent readings around it are reassuringly tight: Rider’s launch test computer showed 46 mpg, ADV Pulse averaged about 43 mpg over a full day of mixed terrain including aggressive throttle work, and MotorcycleDaily’s testing landed in the neighborhood of 45 mpg. Honda CRF450RL performance in normal mixed riding therefore sits credibly in the 43 to 46 mpg band, and the 44.1 mpg figure sits squarely inside it. The digital meter shows average fuel consumption and gallons used, so a rider can judge remaining range.
The 2.0-Gallon Tank Limits Range to Below 100 Miles in Tests
Whatever the exact mpg, Honda CRF450RL performance always runs into the same wall: 2.0 gallons multiplied by any realistic figure stays below 100 miles. At the doc’s 44.1 mpg the arithmetic gives about 88 miles; at MotorcycleDaily’s 45 mpg it gives 90 miles; and in hard use the number falls further — RevZilla’s 2022 one-tank ride saw the fuel light at 51 miles during a 78-mile enduro day and finished with less than an ounce of gas left, while Motorcyclist’s commuter reported around 30 mpg when riding near the bike’s 90 mph top speed. Gentle riding does better — RevZilla’s launch testers averaged 45 to 53 mpg — but even 53 mpg only stretches the tank to about 106 miles. One honest footnote: launch coverage describes a trick titanium 2-gallon tank, while some later listings describe the tank material differently, so sources disagree on construction even though they agree on capacity.
| Fuel economy basis | MPG | Range on 2.0 gallons |
|---|---|---|
| Doc figure (Cycle World dash) | 44.1 mpg | About 88 miles |
| Rider launch test computer | 46 mpg | About 92 miles |
| ADV Pulse mixed-terrain day | About 43 mpg | About 86 miles |
| MotorcycleDaily mixed testing | About 45 mpg | About 90 miles |
| Hard enduro use (RevZilla 2022) | Well below 40 mpg | Fuel light at 51 miles |
| Planning figure | 43–46 mpg | Stop every 80–90 miles |
Honda CRF450RL Real-World Riding Performance
On paper, Honda CRF450RL performance looks like a compromise between a race bike and a commuter. On the road and the trail, it feels much more like the race bike with lights: light, narrow, and eager.
City Riding, Traffic Performance and Low-Speed Fuelling
Around town, Honda CRF450RL performance is better than the race-bike spec sheet suggests, with one well-documented caveat. The single’s torque pulls cleanly from low revs, the bike weighs just 289 pounds with a full tank, and the upright position gives a commanding view over traffic. The caveat is low-speed fuelling: the 2021 remap improved the snatchy throttle and stalling that plagued the 2019–2020 bikes, but testers still describe some abruptness at very low revs. The fuel-injected engine compensates automatically for elevation and weather, and the electric start — there is no kick starter — makes stalling a minor embarrassment rather than a workout. The video below shows the RL at its best: single-track trail riding, where Honda CRF450RL performance matters more than any dyno number.
Highway Riding at 70 MPH, Passing Ability and Seat Comfort
On the highway, Honda CRF450RL performance is competent within clear limits. The bike cruises at 70 mph without strain — testers describe comfortable 60 to 65 mph cruising with very little vibration — but sustained speeds near its 90 mph top bring vibration through the bars, pegs, and seat, and there is no windscreen as standard. Passing ability at highway speed is adequate rather than strong: the engine still pulls in sixth gear, but the bike’s happy place is 60 to 70 mph. Seat comfort is the honest limit on Honda CRF450RL performance as a distance bike: the seat is narrow, tall at 37.2 inches, and shaped for standing on trails, not sitting for hours. For the ownership side — service intervals, common problems, and costs — see our companion CRF450RL reliability coverage.
Honda CRF450RL Handling, Braking and Stability
Honda CRF450RL performance in corners and braking reflects the bike’s brief: a motocross chassis with lights on it, not a street bike with knobby tires. The aluminium twin-spar frame, 28.5-degree rake, 4.8 inches of trail, and 58.9-inch wheelbase give straight-line calm and quick direction changes.
49mm Showa Fork With 12.0 Inches and Rear With 11.8 Inches
The suspension is the most legitimate bragging right in Honda CRF450RL performance. Up front sits a 49mm inverted Showa coil-spring fork with 12.0 inches of travel, adjustable for rebound and compression damping; at the rear, Honda’s Pro-Link single Showa shock delivers 11.8 inches, adjustable for spring preload, rebound, and high- and low-speed compression. Those numbers match or beat the Austrian rivals and dwarf smaller dual-sports — the CRF300L performance comparison shows a full two inches less travel at each end — and they explain why the RL feels at home on terrain that bottoms out lesser bikes. Dirt Bike Magazine’s testers called the suspension excellent and by far the best in the dual-sport world, and even raced a stock-suspended test bike as a night bike in a 24-hour race. For Honda CRF450RL performance, this is the hardware that justifies the price.
260mm Front and 240mm Rear Discs, IRC Tires and Clearance
Braking in Honda CRF450RL performance is strong for the class, period. A single 260mm front disc with a twin-piston caliper and a single 240mm rear disc with the HRC works-type integrated master cylinder must stop a 289-pound bike plus rider, with no ABS on any year, ever. Ground clearance of 12.6 inches pairs with the suspension to let the bike clear rocks and ruts that would ground lower dual-sports, and the 21-inch front and 18-inch rear wheels open up a huge tire choice. Stock tires are IRC GP21 front (80/100-21) and GP22 rear (120/80-18), confirmed on Honda’s own 2026 specification page, and Dirt Rider’s first look notes the same IRC Foot Loose Trails pairing. Testers rate the IRCs as a decent street-and-dirt compromise. The cost of all that clearance is the seat: 37.2 inches claimed, which makes the RL the tallest bike in its class and a non-starter for many riders under six feet without lowering links or a shaved seat.
Honda CRF450RL Performance Compared With Other Street-Legal Enduros
Against its closest rivals, Honda CRF450RL performance trades outright power and premium electronics for price, simplicity, and dealer support.
Honda CRF450RL vs KTM 500 EXC-F and Husqvarna FE 501s
The KTM 500 EXC-F is the RL’s true rival: a 510.9cc SOHC single, street-legal, with a price of $13,499 for 2026 — $3,400 above the Honda’s 2025 price of $10,099. The KTM answers with more power, a lighter chassis, and premium WP suspension, plus ride modes and traction control that the Honda simply does not offer. The Husqvarna FE 501s plays the same game from Sweden: a 510.9cc SOHC single at $13,599 for 2026, with a 42mm Keihin throttle body. What Honda CRF450RL performance gives back is value and simplicity: a bike $3,300 to $3,500 cheaper, with Honda dealer support in every state and a 12-month unlimited-mile warranty. On the trail the gap narrows fast — the RL’s suspension is genuinely competitive, and its power delivery is friendlier for mere mortals. For the buying side of that decision, see our companion CRF450RL buying guide.
| Specification | CRF450RL (2027 doc / 2025) | 500 EXC-F (2026) | FE 501s (2026) |
|---|---|---|---|
| Engine | 449.7cc liquid-cooled single, PGM-FI 46mm | 510.9cc SOHC single | 510.9cc SOHC single, Keihin 42mm |
| Measured power | 36.0–38.0 hp rear wheel | More than the Honda (not quoted here) | More than the Honda (not quoted here) |
| Seat height | 37.2 in | Taller than most street bikes | Taller than most street bikes |
| Curb weight | 289 lb claimed | Lighter than the Honda | Lighter than the Honda |
| Fuel capacity | 2.0 gal | Larger than the Honda | Larger than the Honda |
| Price | $10,199 (2027 doc) / $10,099 (2025) | $13,499 | $13,599 |
The verdict of that table for Honda CRF450RL performance is a three-way split: buy the Honda for value, dealer support, and friendly power; buy the KTM for outright performance; buy the Husqvarna for the same Austrian performance with Swedish ergonomics.
Is the Honda CRF450RL Suitable for Dual-Sport Touring?
Yes for dual-sport touring with modifications, with reservations for long highway touring — and the reservations are the interesting part of Honda CRF450RL performance. For dual-sport touring, the bike’s virtues are real: proven engine, huge aftermarket, 12.6 inches of clearance, and a chassis that eats rough roads. But stock, it is not a touring bike: the 2.0-gallon tank forces fuel stops every 80 to 90 miles, there is no windscreen, and no luggage comes as standard. The fixes are well known: an IMS 3.0-gallon tank, a small windscreen, and soft luggage. For commuting, Honda CRF450RL performance suits short and medium rides brilliantly. The deciding question is not “can it tour” — it can, with a bigger tank — but “how much of your week is dirt?”
Honda CRF450RL Performance FAQs
Direct answers to the questions buyers ask most about Honda CRF450RL performance, drawn from the tested figures in this article.
How much horsepower does the Honda CRF450RL make?
Measured Honda CRF450RL performance is 36.0 horsepower at 7,800 rpm on a 2025 bike (Motorcycle.com dyno), with 26.9 lb-ft of torque at 6,500 rpm; earlier tests measured about 38 horsepower at the rear wheel. Honda publishes no figure; roughly 45 horsepower is a crankshaft estimate, not a factory claim.
What is the top speed of the Honda CRF450RL?
About 90 mph indicated is the best-supported figure for Honda CRF450RL performance, reported by MotorcycleDaily testers. No GPS-verified top-speed figure exists in the sources checked for this article.
Does the Honda CRF450RL have a verified 0-60 time?
No. No instrumented 0-60 mph or quarter-mile test of a stock CRF450RL could be found in this research, so Honda CRF450RL performance quotes no acceleration time.
What MPG does the Honda CRF450RL get?
Honda CRF450RL performance in mixed riding runs about 43 to 46 mpg in tester reports, with the doc’s Cycle World dash figure at 44.1 mpg. Hard enduro use drops well below 40 mpg, and riding near top speed has been reported at around 30 mpg.
How far can a Honda CRF450RL go on a tank?
Plan a stop every 80 to 90 miles on the stock 2.0-gallon tank. At 44.1 mpg the arithmetic gives about 88 miles, and Honda CRF450RL performance in hard trail use can trigger the fuel light as early as 51 miles.
Is the Honda CRF450RL faster than the KTM 500 EXC-F?
No. The KTM 500 EXC-F makes more power from its larger 510.9cc engine and carries a lighter chassis, though Honda CRF450RL performance closes the gap on the trail with competitive suspension and friendlier power delivery — at $3,300 to $3,500 less money.
Does the Honda CRF450RL have fuel injection?
Yes. Honda CRF450RL performance comes from programmed fuel injection through a 46mm downdraft throttle body, which compensates automatically for elevation and weather changes.
Does the Honda CRF450RL have ABS or traction control?
No. Honda CRF450RL performance comes with no ABS, no engine modes, and no traction control on any model year, and braking in the wet is entirely the rider’s job.
Is the Honda CRF450RL good on the highway?
Yes up to about 70 mph, where Honda CRF450RL performance is settled and comfortable. Above that, wind blast and single-cylinder vibration grow, with no windscreen as standard and a narrow seat that punishes long hours.
Is the Honda CRF450RL good for dual-sport touring?
Yes with modifications: a larger tank such as the IMS 3.0-gallon unit, a small windscreen, and soft luggage transform Honda CRF450RL performance into a capable lightweight touring package, but the stock bike’s 80 to 90 mile range limits it.
Why do some websites claim 24 horsepower for the CRF450RL?
That figure is a European restricted-market number mistakenly posted for the 450L, actually belonging to the smaller CRF250L. Honda CRF450RL performance in the US is 36 to 38 rear-wheel horsepower, not 24.
Why do some websites claim over 50 horsepower for the CRF450RL?
Those figures describe the CRF450R motocross bike, not the street-legal RL. Honda CRF450RL performance at 36 to 38 rear-wheel horsepower does not support a 50-plus horsepower claim.
Is the Honda CRF450RL a good beginner motorcycle?
Not usually: despite friendly low-end power, Honda CRF450RL performance comes wrapped in a 37.2-inch seat and race-bred suspension, which makes it a handful for shorter or newer riders at stops. The CRF300L suits beginners better.
