Honda ATC250R Top Speed, Specs, and Review 2022

Honda ATC250R: It was the Honda ATC250R was the greatest three-wheeler that ever came from an established manufacturer. 

It was the ultimate racing machine that was developed in an untimely manner and only half-revived by the TRX250R and its four-wheeled counterpart which inherited the suspension design and its engine.

Honda ATC250R

It was the Honda ATC250R (or Big Red 250R) was introduced in 1981 and was among the first vehicle to increase the power of ATCs in the race. 

With the ProLink suspension system, the Enduro Harley Davidson front look, and a speed of 70 mph top speed The ATC250R was durable and quick.

The Honda ATC250R had so much more to offer, aside from establishing the existence of ATCs on racing tracks. 

Its build quality, durability, and performance made the wheeler popular with the community of riders and to the public generally.

Honda ATC250R

Last Big Red Standing

Honda ATC250R was eighth in the line of all-terrain motorcycles that were released by Honda following the groundbreaking US90 was introduced in the year 1970. 

The racing machine was the first to introduce the 248-/246-cc liquid-cooled engine as well as folding footpegs.

It also had the option of a six-speed and five-speed transmission. These features were not available in the other ATCs that were available at the time. 

Along together with Big Red 250 and 250ES the ATC250R was regarded as the most coveted racing machine designed for recreation and competition. 

It wasn’t until the mid-1980s that Honda expanded its product range to include utility-type equipment designed for use in agriculture and industry.


Many of the enhancements that were made to the ATC250R could be seen in the ATC250R’s 2nd generation (1983 Big Red 250R). 

One of them was an engine-driven counter-balancer that reduced engine vibration, a 30-mm round-slide carburetor with dual disc brakes to provide the power to stop, adjustable air-powered front forks, as well as one fully suspended, gas-charged rear shock. 

The wheel travel increased gradually throughout the 3 generations, from 6.7/4.3 inches back in the year 1981, to 9.8 inches when it was introduced in. The ATC250R’s third-generation (1985 The Big Red 250R) was further improved in the engine, fuel delivery, and engine displacement.

In the Big Red series, the ATC250R was the only model produced from 1981 until 1987. Its twins were the ATC 250SX as well as ATC 250SX, Honda Big Red 350 or Honda ATC350X as well as ATC200 or the Big Red 200 or ATC200 trims – received only one-third of the airtime they did with the general public. 

An earlier model of the ATC250R and was the Big Red ATC250ES, was available outside of the U.S. during the same year that the Consent Decree was implemented. There are a few of these classic vehicles located in Canada, Australia, and Europe.

  • Liquid cooling system


  • Ergonomics and improved handling
  • A slight reduction in dry weight
  • The carburetor’s round-slide size was changed from 34mm to an oval-slide version (for better throttle response)

Why Did Honda Stop Making the ATC250R?

Manufacturers were forced to stop making ATCs (or trikes) because of safety security concerns. The dangers that come when riding a trike were due to the technology and lack of censorship for teens and children who use these bikes. 

As the number of reported ATC-related injuries, accidents, and deaths grew and authorities from the U.S. Justice Department had to enforce in 1988 the Consent Decree, which eventually resulted in a worldwide production prohibition of all-terrain bicycles (ATCs).

Reviving the Mighty ATC250R

The modifications that follow, as well as racing abilities similar to Mickey Dunlap, the legend of Mickey Dunlap, are guaranteed to return the ATC250R back to its speed-demon status:

Power Gain

The installation of a brand new hot Rods crankshaft (designed specifically for the TRX250R) that has no power valve in the ATC250R chassis will not only give you an increased rod angle, it additionally, but also breaks the rear end free for turning. 

If you use an extra spacer plate, the configuration allows for a longer time to switch ports, leading to increased torque and improved throttle responsiveness. 

In the same way, professional cylinder porting/decking of cylinders along with head re-chambering as well as top-end gasket modifications assist the three-wheeler in gaining mid-range power. 

It significantly improves the vehicle’s power curve as well as access across the entire range of RPMs and increases the compression. Make sure you have a hundred percent Octane Rating to keep the fuel you use to move forward.

Motocross Adaptability

Installing a replacement for the original carriage with a billet aluminum bearing house and mounting a racing axle will help increase the width, strength, and stability needed for the motocross. 

The billet housing includes the highest-quality twin-row bearings. Similar to the Pro Racing axle allows up to 3 inches of width adjustments depending on the track conditions. 

The machine can be set to the maximum width in most MX ATV events. The machine also includes an axle hub made of billet and some parts dealers provide an unlimited warranty on the purchase.

Race-Ready Suspension

Valve emulators work best when used in conjunction with standard suspensions, mimicking the functions of a cartridge fork, and permitting the rebound and compression circuits to be tuned separately. 

It is possible to pair the device with a set of springs forks that are progressive in rate (which are stiffer at the close to the length of travel), Chromoly rear swingarm and high-flow valve pistons, and custom-designed valves. 

In particular, the new swingarm comes with new needle bearings as well as twin pinch bolts that are located on each side of the back. 

This will reduce twisting in the carrier, as well as strengthen the crack-prone areas of standard swingarms.

High-Performance Ignition

The ignition system is a boon for the ATC250R. The ATC250R has a lighter flywheel and different ignition curves that greatly increase the buildup of the engine’s RPM. 

The flywheel’s weight is reduced, which is ideal for a professional-caliber engine, but it may not be suitable for trail riding casually.

Ease of Navigation

The rubber used in the stock tires that allowed the sliding easy was made of more brittle rubber than the modern-day MX tire. 

However, the tires’ dimension (23 8-11) is somewhat unusual in comparison to modern standards and is difficult to find. 

If you’re looking to transform your ATC250R into a machine that can be used for motocross It is recommended to choose 18x 9.5-8 tires. 

They’re the right dimensions and height that are suitable for motocross events and allow the back end to come loose quickly.


To make your trike’s cockpit look modern switch your old handlebars to Renthal bar handles (view at Amazon). 

Also, Ez-fit Nerf Bars (view on Amazon) are more appealing for your motorcycle than feet that came with the stock ones and provide greater traction and a better feeling.

The new aftermarket fenders, plastics, and radiator shrouds make the trike’s appearance back to its previous glory. Beadlock wheels with a billet center offer security and enhance the car’s glamour.

Even with these improvements, the ATC250R is not without flaws that remain unsolved. 

The connection between the bars and footpegs, not fitting to taller people, a low seats, as well as difficulties when it comes to egress and ingress, to mention some. But, the completion of all of these stages is guaranteed to transform your ATC250R into its former glory. Racetrack King it once was.

If you’re not finding this build difficult enough, then the missile kit for ATC250R or a two-wheel conversion could be a more appropriate task to take on.
