The TRX 450R is high performance All-terrain vehicle manufactured by Honda powersports. It was produced from 2004 to 2014.
While the CRF450R [1] and the TRX450R [2] share the same displacement number, there are very few of the same components between the two engines. Initially, many people were disappointed because the first TRX450R was very weak compared to the CRF450R. Honda claims that it designed the TRX450R engine to produce more torque so that the engine was more suited for ATV purposes. In 2004 and 2005, the only interchangeable part between the ATV and motorcycle engines was the camshaft. In 2006, Honda overhauled the TRX450R engine to make it more similar to its motorcycle variant. This included a more aggressive cam profile, a larger bore with a shortened stroke, a new, short skirt piston and titanium rather than steel valves. In addition, Honda changed the carburetor from a 42 mm Keihin butterfly type to a 40 mm Keihin FCR. This increased the power from about 33 horsepower (25 kW) in the first generation to over 41 horsepower (31 kW) in the second. The first generation engine had a 10.5:1 compression ratio while the second generation had a 12:1 compression ratio.
Because for many years the four-stroke class displacement limit was 440 cubic centimeters, many racing sanctions bumped this number up to allow the new 450 cc bikes and ATVs to compete.
Along with the introduction of the TRX 450R, Honda announced, after 17 years, it would once again support factory sponsored racing. The 450R would be the first factory sponsored bike out of any of the other atv manufacturers. Honda's first sponsored rider on the new 450r would be Tim Farr. The sponsored Honda team would compete in the ATVA MX and TT Nationals in the Pro-Production class. The 450r's first national race would be the 2003 Baja 1000.
The 450R was off to a good start even before its public launch. The 450R was first across the line in the ATV class with a total time of 22 hours, 27 minutes, and 24 seconds. With an average speed of 37 mph (60 km/h). In the 2004 National MX races, the 450R would place 3rd overall.
Desert racing, and track racing would not be the only events the 450R would race in. The 450R would also compete in the Grand National Cross Country series although Honda would not sponsor any riders.

Motocross is a form of off-road motorcycle racing held on enclosed off-road circuits. The sport evolved from motorcycle trials competitions held in the United Kingdom.
The Honda XR series is a range of four-stroke off-road motorcycles that were designed in Japan but assembled all over the world.
The E-series was a line of inline four-cylinder automobile engines designed and built by Honda for use in their cars in the 1970s and 1980s. These engines were notable for the use of CVCC technology, introduced in the ED1 engine in the 1975 Civic, which met 1970s emissions standards without using a catalytic converter.
The Honda A series inline-fourcylinder engine is used in 1980s Honda Accord and Prelude models. It was introduced in 1982, with the second-generation Honda Prelude, and available in three displacement sizes: 1.6-, 1.8- and 2.0-liters. It features cast iron block and aluminum SOHC head design with three valves per cylinder for a total of 12 valves. It was available in carbureted and fuel-injected configurations
The Honda D series inline-four cylinder engine is used in a variety of compact models, most commonly the Honda Civic, CRX, Logo, Stream, and first-generation Integra. Engine displacement ranges between 1.2 and 1.7 liters. The D Series engine is either SOHC or DOHC, and might include VTEC variable valve timing. Power ranges from 66 PS (49 kW) in the Logo to 130 PS (96 kW) in the Civic Si. D-series production commenced 1984 and ended 2005. D-series engine technology culminated with production of the D15B 3-stage VTEC (D15Z7) which was available in markets outside of the United States. Earlier versions of this engine also used a single port fuel injection system Honda called PGM-CARB, signifying the carburetor was computer controlled.
The Honda CR series is a range of off-road motorcycles made by the Honda corporation from 1973 onwards.
The Honda H engine was Honda's larger high-performance engine family from the 1990s and early 2000s. It is largely derived from the Honda F engine with which it shares many design features. Like Honda's other 4-cylinder families of the 1980s and 1990s, It has also enjoyed some success as a racing engine, forming the basis of Honda's touring car racing engines for many years, and being installed in lightweight chassis for use in drag racing. The F20B is a part of the F-series family of engines; it is basically a cast-iron sleeved down destroked version of the H22A. It was developed by Honda to be able to enter into the 2-liter class of international racing.
The Kawasaki KLR250/KL250D was a motorcycle produced from 1984 to 2005 as the successor to the 1978 to 1983 KL250C, with only minor changes during the model run. This lightweight dualsport motorcycle was used for several years by the US military for a variety of tasks, including messenger duty and reconnaissance.
The L-series is a compact inline-four engine created by Honda, introduced in 2001 with the Honda Fit. It has 1.2 L (1,198 cc), 1.3 L (1,318 cc) and 1.5 litres (1,497 cc) displacement variants, which utilize the names L12A, L13A and L15A. Depending on the region, these engines are sold throughout the world in the 5-door Honda Brio Fit/Jazz hatchback Honda Civic and the 4-door Fit Aria/City sedan. They are also sold in the Japanese-only Airwave wagon and Mobilio MPV.
The Honda CRF series is a line of four-stroke motocross, trail, and dual sport motorcycles manufactured and marketed by Honda.
The Yamaha WR450F is an off-road motorcycle made by Yamaha Motor Company. It currently has a 450 cc (27 cu in) liquid-cooled single-cylinder engine. First offered in 1998 at 400cc, it shared many components and design concepts with the YZ400F motocross model. It is basically the racing YZ450F detuned slightly for more controllable power, with a headlight and lighting coil, softer suspension, a kickstand, lower noise specifications, larger radiators and lower emissions. The WR in the name indicates a wide-ratio gear box common to most enduro or trail bikes and stands in contrast to the close-ratio gearbox essential to a motocross racer. Over the years the WR has benefited from the advances made in the YZ motocross version gaining displacement and advancements such as an aluminum frame and improved suspension. Over much of its life the weight of the WR450F has remained fairly constant ranging from 244 to 249 pounds dry weight.
The Honda TRX250R was a sport ATV manufactured by Honda between 1986 and 1989. It combined a lightweight frame and good handling, with a liquid-cooled two-stroke engine and six-speed close-ratio transmission. Although only being manufactured for four years, the "250R", as it was known, was long a primary choice for ATV racers until the resurgence of factory involvement and usage of four-stroke engines in sport ATV's beginning in 2003 and 2004.
The Yamaha YZ450F is a four-stroke racing motocross bike built by Yamaha Motor Corporation. It was the successor to the previous YZ426F which was discontinued in 2003. It is credited by Cycle World and Dirt Rider magazines as the bike that started the four-stroke dirt bike revolution. The 2006 YZ250F and YZ450F were the first production motorcycles equipped with titanium suspension springs.
The Honda CR250R was a Honda racing dirt bike. The prototype was built in 1971, but it was not until late 1972 that production of the 1973 model "out of the box racers" began sale to the general public. The CR250 was produced for nearly 37 years, 2007 being the final year of production.
The ATC250R is a high-performance, three-wheeled ATV produced by Honda from 1981 to 1986. Cited at the first high performance ATC introduced, production began with an air-cooled, 248 cc single-cylinder two-stroke engine, but would see a liquid-cooled, 246 cc engine by 1985. All model years were fully suspended and adjustable, using air-assisted front forks and a single, remote reservoir gas-charged rear shock. 1981-1982 models offered 6.7 inches of front suspension travel and 4.3 inches in the rear, 1983-1984 offered 8.7 inches in front and 8.1 inches rear, while post-1985 Models allowed 9.8 inches of travel. All model years also used a gear-driven counter-balancer to reduce engine vibration. Dual disc brakes were used on all model years, with the exception of the 1981, which used a front disc and a rear drum.
The Honda CRF150F is an off road motorcycle that was introduced in 2003 as the successor to the Honda XR series. The 150F Is a bike for beginner to intermediate riders, teens or adults. It is mainly used for family recreation and easy off road trails. It has a relatively soft suspension, wide seat and high ground clearance.
