What is the most powerful 450 motocross bike?
450 MOTOCROSS BIKE FACTS: IT'S ALL ABOUT THE NUMBERS — HORSEPOWER, TORQUE, PRICE & WEIGHT
- At 6000 rpm, the Kawasaki KX450 makes the most horsepower (37.68).
- At 8000 rpm the CRF450 takes over with an impressive (54.67) ahead of the KTM's (53.92) and Husqvarna's 52.92.
The Kawasaki KX 450F is a liquid-cooled DOHC 449 cc (27.4 cu in) four-valve four-strokesinglemotocrossmotorcycle made by Kawasaki.
Since 2007, it has also come in the KLX450R versions, which has added conveniences that make it more suitable for trail riding, green laning, enduro events, and lower speed riding in general. This is due to the larger gas tank, 18 inch rear wheel, headlamp, and electric start, and a retuned engine that has less peak horsepower in favor of easier handling from more lower end torque delivered more smoothly.
First Generation 2005-2008
Unlike the Kawasaki KX250F, the KX450F was not co-developed under joint-venture with the Suzuki Motor Co. and differed greatly from Suzuki's 450cc offering. The first year of the KX450F was 2005, but the machine suffered catastrophic frame failure during the Japanese MX season. As a result, plans for a 2005 retail version were postponed and the KX450F debuted as a 2006 model in most markets.
Initial reviews of the KX450F were tepid, citing a positive response to the engine and power delivery, but finding the suspension and geometry of the bike unsatisfactory. Reviewers also took exception to the choice of a 4-speed transmission, as Kawasaki chose to break from the industry standard by not to include a fifth gear.
Despite these perceived shortcomings, the 2006 Kawasaki KX450F would win both the AMA World Supercross GP title and the BooKoo Arenacross title, as well as the Hare and Hound title.
For 2007, the KX450F received a series of minor engine and frame refinements, but the most notable upgrade was a 5-speed transmission. The transmission received a slightly taller 1st gear, while second through fourth remained the same and the fifth added.
Second Generation 2009-2011
The next major innovation would be in 2009, as Kawasaki introduced fuel injection. Reviewers raved of the performance effect of the new injectors, and in proceeding years the technology would spread across the KX lineup.
Third Generation 2012-2015
A series of major revisions came in 2012. The KX450F received an all new frame, significant engine modifications and a new electronics set that included Launch Control. Launch Control is designed to prevent wheel-spin at take off, and automatically disengages once third gear is reached. It is activated by holding a switch until an indicator light glows green, at which point the bikes computer modifies acceleration factors. Kawasaki has continued to insist since inception (for safety reasons) that this system is not traction control but a unique system onto itself.
These later models allow for extensive customization of the ECU using Kawasaki's optional software system, as well as including a Digital Fuel Injection (DFI) coupler system. DFI couplers allow for immediate trackside changes to the ECU through the simple change of a plug-and-play module. Kawasaki provides three modules with new bikes, a Green (standard mapping), White (soft track conditions mapping) and Black (hard track conditions mapping).
Fourth Generation 2016-2018
The 2016 KX450F is a new redesign from 2015, including significant changes to the engine, chassis and throttle body.
Fifth Generation 2019-Present
In 2019, Kawasaki dropped the F from the name. The 2019 KX450 is an all-new design, which includes electric start and eliminates the kick starter. The fork was switched from an air fork to a coil-based Showa fork, leveraging A-Kit technology.

How much power does the all-new 2019 Kawasaki KX450 make?
By Andrew OldarAugust 27, 2018
The 2019 Kawasaki KX450 has a starting suggested retail price of $9,299 and is available in green. Powering this Japanese motorcycle is a liquid-cooled, DOHC, four-valve, 449cc four-stroke engine. We ran the KX450 on our rear-wheel dyno to determine peak output from Kawasaki's flagship motocross bike. We documented 52.63 hp at 9,480 rpm and 32.80 pound-feet of torque at 6,730 rpm.
The 2019 model marks the beginning of Kawasaki’s newest generation of what was previously known as the KX450F. However, the Japanese manufacturer has dropped the “F” from its naming convention as it only produces four-stroke motocross bikes. In addition to the chassis and suspension, the engine on the KX450 is completely new, and features electric start and a hydraulic clutch. The valve train uses designs from Kawasaki’s World Superbike engineers with finger-follower actuation, larger-diameter titanium valves, and more aggressive cam profiles. Additional new components are the 44mm throttle body, downdraft-style intake routing, engine cases, bridged-box piston, header pipe, shift drum, and shift fork.
"The 2019 KX450 engine retains the previous generation's already-good power delivery type and improved upon it with noticeably more power in each part of the rpm range." —Andrew Oldar

Correspondingly, how much horsepower does a 2019 kx450f have?
Last year's 2018 KX450F engine was one horse better at 6000 rpm, 7000 rpm, 8000 rpm and 9000 rpm. After 9400 rpm, the 2019 KX450 finally made more power (three more horses at 11,000 rpm). Peak horsepower was 56.4 for the 2018 engine at 8800 rpm and 55.3 horses at 9500 rpm for the 2019 model.
Secondly, how much horsepower does a kx500 have? In stock trim the KX500 makes in the realm of 63 horsepower and has 40-plus foot-pounds of torque. It is a lighter bike than the new-aged 250Fs and more powerful than all of the 2017 450 four-strokes.
Keeping this in view, how much horsepower is a 450cc?
Peak horsepower doesn't always fall on an even number, but it is where the engine reaches its maximum number. The Honda CRF450 peaks at 60.21 horsepower and the remaining five engines fall off in half horsepower increments from 57.51 (Yamaha) to 57.14 (KTM), 56.40 (Husqvarna), 55.86 (Kawasaki) and 54.39 (Suzuki).
