Short answer: Honda CRF450R-S performance is donor-bike performance, and this Honda CRF450R-S performance guide says so plainly. No dyno test of an actual R-S was ever published, so every horsepower number here comes from the donor bikes the R-S is based on, labelled as such every time. The 2023–2024 R-S is a 2022 CRF450R at a value price — $8,799 for 2023 and $8,899 for 2024 before destination — with the same 449cc Unicam engine, the same 46mm throttle body, and the same chassis, minus the updates the standard R received in 2023 and 2024. There is no Honda top-speed figure, no instrumented 0–60 test, and no EPA mileage rating for this bike, and this Honda CRF450R-S performance guide never prints aggregator numbers as facts. The R-S is a closed-course competition motorcycle only, discontinued after 2024, and its performance story is simple: nearly all of the standard bike’s speed for $800 less.
One framing fact belongs up front in this Honda CRF450R-S performance guide: the R-S is Honda’s value motocrosser, not a special edition and not a Works bike. The RWE/Works Edition sits at the premium end of the range — $12,399 plus destination for 2023 — while the R-S sits at the value end. Honda never explained what the “S” stands for, and this Honda CRF450R-S performance guide does not invent an expansion. Two generations also share the badge and must never be mixed: the 2022 R-S is the proven 2020 CRF450R with twin mufflers and a cable clutch, while the 2023–2024 R-S is based on the 2022 CRF450R with a single muffler and a hydraulic clutch. Every figure here carries its model year.
Honda CRF450R-S Engine Performance and Power Delivery
The engine story of Honda CRF450R-S performance is a story about a proven engine sold at a discount. Both generations run a 449cc liquid-cooled Unicam single with a 46mm throttle body and a close-ratio five-speed, and both deliver the strong low-end and midrange character that made the donor bikes popular. The R-S never got the 2023 standard R’s revision — a smaller 44mm throttle body, revised mapping, and a revised frame — so its power character stays with the 2022 platform.
Platform Dyno Data Comes From the 2020 and 2022 Donor Bikes
Platform dyno data comes from the 2020 and 2022 donor bikes, because Honda CRF450R-S performance was never measured on a dyno under the R-S badge. For the 2022 R-S, the donor is the 2020 CRF450R, and MXA’s 2020 race test recorded 59.74 horsepower at 9,600 rpm for that bike, with the 2019 version making 60.21 horsepower at 9,500 rpm on the same dyno. MXA called the 2020 bike the king of horsepower hill, while noting that its power advantage did not arrive until high rpm and that the KTM 450SX-F led below that point. For the 2023–2024 R-S, the donor family is the 2021 redesign carried into the 2022 CRF450R, and Dirt Bike Magazine’s FMF Dynojet test recorded 57.21 horsepower at 9,300 rpm and 35.64 lb-ft of torque at 6,930 rpm for the 2021 CRF450R. Test riders thought the Honda felt like the most powerful bike of the group, reacting to a zone between 7,500 and 8,500 rpm where it gained about 6 horsepower faster than any rival. MotoHead’s 2020 test recorded 53.6 bhp, but that is a different dyno and standard, so it is never averaged with the MXA or FMF numbers here.
No R-S-Specific Dyno Test Was Published: Label Sibling Data
No R-S-specific dyno test was published, and this Honda CRF450R-S performance guide treats that as a rule, not a footnote. Every horsepower figure here is sibling data — a donor bike’s number, standing in for a bike that shares its engine — and it is labelled as sibling data at every mention. That labelling matters because the two R-S generations have different donors: quoting the 59.74-horsepower MXA figure for a 2024 R-S would be wrong, since the 2024 bike’s donor is the 2022 platform, not the 2020 bike. Equally, dyno figures from the 2025–2026 CRF450R platform belong to a different generation entirely and never appear here. In short, the R-S makes roughly 57 to 60 horsepower depending on the donor dyno, with its strength in the low-end and midrange rather than at peak rpm.
| Dyno (labelled sibling data) | Donor bike | Peak power | Peak torque |
|---|---|---|---|
| MXA race test | 2020 CRF450R (2022 R-S donor) | 59.74 hp @ 9,600 rpm | Not quoted in that test summary |
| Dirt Bike / FMF Dynojet | 2021 CRF450R (2023–24 R-S donor family) | 57.21 hp @ 9,300 rpm | 35.64 lb-ft @ 6,930 rpm |
| Summary | No R-S dyno exists | 57–60 hp donor range | Honda CRF450R-S performance: low-end and midrange strength |
Honda CRF450R-S Top Speed and Acceleration
Top speed and acceleration are where Honda CRF450R-S performance coverage most often goes wrong, because the numbers buyers want do not exist for this bike. There is no Honda top-speed figure, no instrumented 0–60 test, and no quarter-mile test for the R-S, and this Honda CRF450R-S performance guide refuses to fill those gaps with aggregator inventions.
No Honda Figure and No Instrumented Test Exists: Estimates Only
No Honda figure and no instrumented test exists for R-S top speed or acceleration, and that absence is itself useful Honda CRF450R-S performance information. Motocross bikes are geared for tracks, not speed traps: a close-ratio five-speed and a 13T/49T final drive with a #520 chain mean the bike runs out of gearing on any long straight. What can be said about acceleration is qualitative but well supported by the donor tests: the low-end torque advantage means the bike pulls hardest where races are won — out of corners, up jump faces, and off the start gate. Any top-speed estimate is just that, an estimate from gearing, and this Honda CRF450R-S performance guide labels it as one, never a specification.
Aggregator Speed and MPG Figures Are Inventions to Avoid
Aggregator speed and MPG figures are inventions to avoid, and this Honda CRF450R-S performance guide names the pattern so readers can recognize it elsewhere. Spec-aggregator sites print top-speed and fuel-economy numbers for the R-S that trace to no Honda document, no magazine test, and no instrumented measurement — they are numbers generated to fill a spec table, and repetition has made them look authoritative. They are not. This bike has no credible top speed and no credible MPG figure, and a buyer who plans around an aggregator number is planning around fiction.
Honda CRF450R-S Mileage and Fuel Economy
Honda CRF450R-S performance mileage is measured in motos, not miles per gallon — the tank size translated into race reality, the only honest fuel question for a closed-course bike.
No MPG Rating Exists for a Closed-Course Competition Bike
No MPG rating exists for a closed-course competition bike, and Honda CRF450R-S performance writing should never pretend otherwise. The EPA does not rate motocross bikes, Honda publishes no fuel-economy figure for the R-S, and no magazine runs a mileage loop on a bike with no odometer and no street-legal status. Fuel use swings wildly with track, throttle, and gearing, so even an honest one-day figure would mislead. The useful fuel question is not miles per gallon but whether the tank lasts the race — answered below. Riders who need a planning number should use their own hour meter and fuel logs.
The 1.7 Gallon Tank and Real Range Between Motos
The 1.7 gallon tank and real range between motos is the practical Honda CRF450R-S performance fuel story. The 2023–2024 R-S carries a 1.7-gallon tank, and the 2022 bike carries 1.66 gallons exact per Honda’s spec sheets, a figure most coverage rounds to 1.7 gallons — this Honda CRF450R-S performance guide keeps the per-year figures separate and uses the rounded figure in prose. That capacity suits a moto format: a full tank covers a practice session and a moto, and the titanium tank on the 2024 bike keeps weight low. For the trail-riding sibling with different range priorities, see our CRF450X performance guide.
Honda CRF450R-S Real-World Riding Performance
Real-world Honda CRF450R-S performance is where donor dyno charts meet dirt, and character depends on generation: the 2022 bike feels like the proven 2020 machine it is, the 2023–2024 bike like the calmer, more refined 2022 platform. Neither feels like the 2023 or 2024 standard R, because the R-S never received those updates.
Track Riding Character of the Older-Generation Platform
Track riding character of the older-generation platform is the heart of Honda CRF450R-S performance. The 2023–2024 R-S inherits the 2022 CRF450R’s character: a strong, usable engine with a wide powerband, a chassis praised for cornering, and suspension that works for a broad range of riders. The 2022 R-S inherits the 2020 bike’s character: a more aggressive, peakier machine that demands more from its rider, with the twin-muffler exhaust and the older frame. Both generations share one trait — the engine’s low-end and midrange strength makes the bike easy to ride fast without constantly chasing peak rpm, which is exactly what a value buyer wants. The 2023 standard R’s revisions — a smaller 44mm throttle body, a stiffer frame, and steel engine hangers — never reached the R-S, which keeps the 2022 bike’s 46mm throttle body. That is not a downgrade to apologize for: the bigger body suits the R-S’s broad powerband, and this Honda CRF450R-S performance guide never presents 46mm as inferior.
Hydraulic Clutch and the 2021 Redesign It Never Received
Hydraulic clutch and the 2021 redesign it never received is a heading about the 2022 bike, and this Honda CRF450R-S performance guide keeps it that way. The 2022 R-S kept the 2020 platform’s cable clutch, because the 2021 redesign — single-muffler exhaust, hydraulic clutch, central-port head with an oval exhaust port, and a narrower frame — never reached that bike. The 2023–2024 R-S is a different story: its donor, the 2022 CRF450R, did receive the 2021 redesign, so the later R-S bikes do have a hydraulic clutch. Buyers should check the clutch on the actual bike in front of them: cable means a 2022 R-S, hydraulic means a 2023–2024 R-S.
The video below in this Honda CRF450R-S performance guide is Swapmoto Live’s first test of the 2021 CRF450R — the donor platform for the 2023–2024 R-S, honestly labelled as a donor-platform test, not an R-S test.
Honda CRF450R-S Handling, Braking and Stability
Handling is Honda’s traditional strong point, and Honda CRF450R-S performance in corners is where the donor platform earns its keep — testers of the 2022 platform praised its cornering precision and balance, and the R-S inherits both at a lower price.
49mm Showa Fork With 12.2 Inches and Pro-Link Rear
49mm Showa fork with 12.2 inches and Pro-Link rear is the suspension headline of Honda CRF450R-S performance for the final bike. The 2024 R-S runs a 49mm inverted Showa fork, rebound and compression adjustable, with 12.2 inches of travel, paired with a Pro-Link Showa single shock, spring-preload, rebound, and compression adjustable, with 12.4 inches of travel. Per-year difference: the 2022 R-S fork travel is 12.0 inches per Ultimate Motorcycling, not the 2024 bike’s 12.2 inches. The twin-spar aluminum frame carries a 58.3-inch wheelbase, 27.1 degrees of rake, and 4.5 inches of trail on the 2024 bike, with a 37.8-inch seat and 13.2 inches of clearance.
260mm Front Disc and MX33 Tires on the Final 2024 Bike
260mm front disc and MX33 tires on the final 2024 bike complete the Honda CRF450R-S performance chassis picture. Braking is a single 260mm front disc with a twin-piston caliper and a single 240mm rear disc — proven hardware shared with the donor bike. Tires are Dunlop MX33 rubber on the 2023–2024 R-S, sized 80/100-21 front and 120/80-19 rear, while the 2022 R-S wears Dunlop Geomax MX3S tires from its 2020 platform. Tire choice matters for Honda CRF450R-S performance because the MX33 is a current race tire with strong drive grip, while the older MX3S is a previous-generation compound — another honest difference between the generations.
Honda CRF450R-S Performance Compared With Other 450 Motocross Bikes
Comparison is where Honda CRF450R-S performance becomes a buying decision: the R-S does not compete with new 450s on freshness — it competes on value, at a price no current bike can match.
Honda CRF450R-S vs the Same-Year CRF450R: the Real Gap
Honda CRF450R-S vs the same-year CRF450R is the real gap, and this Honda CRF450R-S performance guide states it in dollars: $1,000 for 2022 ($8,599 vs $9,599) and $800 for 2023 and 2024 ($8,799 vs $9,599 in 2023; $8,899 vs $9,699 in 2024). What the extra money buys on the standard R is the latest generation: for 2023, revised engine mapping, the smaller 44mm throttle body, a revised frame, and steel engine hangers; for 2024, further refinements the R-S also skipped. It does not buy a different engine family or character — the R-S keeps the same 449cc Unicam single, 46mm throttle body, and fundamental chassis. Dirt Rider’s 2023 CRF450R technical coverage confirms the R-S position: offered for years with fewer updates but not less performance for the rider looking to save money, and for 2023 fully based on the 2022 model. For the full model story, see our CRF450R-S review, and for the standard bike’s own numbers, see our CRF450R review. MXA’s first look at the 2023 Honda motocross models likewise frames the R-S as the value answer for customers who prioritize price without a big performance sacrifice.
Is the Honda CRF450R-S Suitable for Beginner Riders? No
Is the Honda CRF450R-S suitable for beginner riders? No — and this Honda CRF450R-S performance guide says why plainly, because the doc heading demands a straight answer. A 450 motocrosser makes roughly 57 to 60 horsepower on donor dynos, weighs 244 to 247 pounds depending on year, has a 37.8-inch seat height, demands race-hours maintenance, and offers no beginner mode that changes any of that: the engine maps and traction control tune delivery, they do not tame a race bike into a learner bike. The R-S is also closed-course only, not street legal in any US state, and carries no warranty framing as a competition bike. Beginners belong on a smaller trail bike. Honda CRF450R-S performance is expert equipment at a value price, but still a closed-course competition motorcycle. For the service reality behind the riding, see our CRF450R-S reliability guide, and for the full buying decision, see our CRF450R-S buying guide. One pricing trap: the Kawasaki KX450F lists at $10,299 for 2027, while the $10,599 figure that circulates is the KX450FX cross-country bike — never price the motocrosser at $10,599, and never compare a discontinued value bike’s price against a current-year rival without labelling the years.
Honda CRF450R-S Performance FAQs
Direct answers to the Honda CRF450R-S performance questions buyers and racers ask most, with every figure labelled by source and model year.
How much horsepower does the Honda CRF450R-S make?
No R-S dyno was ever published, so this Honda CRF450R-S performance guide gives donor figures only: MXA’s 2020 test recorded 59.74 hp at 9,600 rpm for the 2022 R-S donor, and Dirt Bike’s FMF Dynojet test recorded 57.21 hp at 9,300 rpm for the 2023–2024 R-S donor family. Always name the donor and the dyno.
What is the Honda CRF450R-S top speed?
There is no Honda figure and no instrumented top-speed test, so this Honda CRF450R-S performance guide states no top speed — aggregator figures are inventions.
What MPG does the Honda CRF450R-S get?
No MPG rating exists for a closed-course competition bike, and this Honda CRF450R-S performance guide gives none. Range is measured in motos: the 2023–2024 bike’s 1.7-gallon tank covers a practice session and a moto.
What gearing does the CRF450R-S use?
For Honda CRF450R-S performance: a close-ratio five-speed with a 13T/49T final drive on a #520 chain, the same on both generations. The 2025–2026 standard R’s 13/51 gearing never applied to the R-S.
Does the CRF450R-S have a hydraulic clutch?
It depends on the year, says this Honda CRF450R-S performance guide: the 2022 R-S kept the 2020 platform’s cable clutch, while the 2023–2024 R-S has a hydraulic clutch from its 2022 donor platform. Check the actual bike.
Does the CRF450R-S have launch control and traction control?
Yes: for Honda CRF450R-S performance starts, HRC launch control and Honda Selectable Torque Control, switched from the handlebar. The 2022 bike’s exact map and HSTC mode counts should be checked against the 2020-platform list, not assumed from the later bike.
What is the difference between the 2022 and 2024 CRF450R-S?
For Honda CRF450R-S performance buyers: the 2022 bike is the 2020 platform with twin mufflers, a cable clutch, 247 lb, and MX3S tires, while the 2024 bike is the 2022 platform with a single muffler, a hydraulic clutch, 244 lb, and MX33 tires. Different donors, different bikes.
How much does a CRF450R-S cost?
For Honda CRF450R-S performance shoppers: $8,599 plus $400 destination for 2022, $8,799 plus $600 for 2023, and $8,899 plus $600 for 2024 — $1,000 under the 2022 standard R and $800 under the standard R in 2023 and 2024. The bike is discontinued after 2024.
Is the CRF450R-S a Works Edition?
No, says this Honda CRF450R-S performance guide: the R-S is Honda’s value motocrosser. The Works Edition is the premium line — $12,399 plus destination for 2023 — at the opposite end of the range.
What does the S in CRF450R-S stand for?
Honda never explained it, says this Honda CRF450R-S performance guide. No expansion — not Special, not Sport, not Standard — appears in any Honda source, so none is given here.
Is the Honda CRF450R-S good for beginners?
No. For Honda CRF450R-S performance buyers, this is an expert-level closed-course race bike: roughly 57 to 60 donor horsepower, a 37.8-inch seat, race-hours maintenance, no warranty framing, and no street legality. Beginners should start on a smaller trail bike.
Is the CRF450R-S street legal?
No, says this Honda CRF450R-S performance guide: the R-S is closed-course only and not street legal in any US state. Honda’s “year-round off-road-legal in all 50 states” wording refers to off-road access, not road use.
