Fuel injection has been the norm for motocrossers with greater displacements, and it is gradually making its way down to the 250cc class. The 2010 CRF250R will get a new, entirely redesigned fuel-injected engine along with a new frame, according to a recent announcement from Honda. It’s interesting to see that Honda has reinstated a single exhaust system for 2010. Here are all of Honda’s specifications.
The 2010 CRF250R maintains Honda’s long-standing status as the undisputed leader in its class thanks to an entirely new, more powerful, and more compact engine with Programmed Fuel Injection (PGM-FI) and an entirely new Twin Spar Aluminum Frame with the Honda Progressive Steering Damper (HPSD). The most recent CRF250R raises the bar with remarkable power and class-leading handling combined in a package that is fit for racing.

The CRF250R from 2009 uses fuel injection.
The 250R wasn’t completely redesigned for 2009, unlike the larger bike; it didn’t have fuel injection or sleek new bodywork, however a new white rear fender marginally changes aesthetics.
The CRF 250R from 2012 uses fuel injection.
A 46mm throttle body with a 12-hole injector and a lightweight 50-psi pump are used in the Programmed Fuel Injection (PGM-FI) system to provide optimal fuel atomization and accurately focused fuel charge. System reduces fuel usage as well.
The CRF250R from 2014 uses fuel injection.
A preview of the 2014 Honda CRF250R motorcycle
Honda unveiled a completely redesigned CRF450R last year that had little in common with the 2012 model. The motocross motorcycle was marketed at the same $8,440 MSPR as the 2012 model despite receiving numerous suspension and engine modifications.
Honda did not, however, improve the CRF250R. But in 2014, this is different because the 2014 CRF250R is given the same treatment as the 2013 CRF450R. Designed especially for what Honda refers to as “The 2014 Honda CRF250R boasts a whole new engine and chassis that are both referred to as Generation Scrub. A new dual-timing fuel-injection system, a new cylinder head, a new piston, a higher compression ratio, and a new transmission were all added to the engine. According to Honda, the engine now produces more track-ready mid-range power. In terms of the chassis, the frame is made to reduce the center of gravity of the CRF250R. Additionally, a dual-muffler exhaust system is added to the bike “increase handling precision by concentrating the bike’s weight. Honda did not disclose the MSRP for the 2014 CRF250R, but if it follows the same pattern as the CRF450R, it should cost the same as the 2012 model ($7,420). The 2012 Honda CRF250R’s characteristics and specifications are listed below. New features on the 2014 Honda CRF250R:
- A patented debris-shielding design is present in the improved footpeg mount.
- The bike’s bulk is centralized by an entirely new short and compact dual-muffler exhaust system, which further sharpens handling.
- A 249cc Unicam engine that has undergone extensive revisions offers a significant amount of midrange punch with a new cylinder head, new piston, and increased compression ratio.
- new, lighter airbox and subframe
- To help reduce the bike’s center of gravity, brand-new radiators are installed lower in the chassis.
- The total package gains sturdiness and longevity thanks to a redesigned transmission.
- The brand-new aluminum frame is intended to reduce the bike’s center of gravity and increase its level of maneuverability, making it an undeniably flickable vehicle.
- In addition to helping to increase power, a new Dual-Timing PGM-FI fuel injection system also improves throttle responsiveness and control at partial throttle openings.
The CRF450R from 2008 uses fuel injection.
The Honda CRF450R faces competition with equal performance. The Yamaha YZ450F is one of the most potent and maneuverable 450s ever made. It was the first four-stroke motorcycle and continues to advance thanks to chassis and engine improvements that guarantee the five-titanium-valved YZ540F, the beating heart of the open-class pack.
For 2008, Suzuki also unveiled a brand-new version of the RM-Z450, and they contend that their fuel-injected vehicle heralds the beginning of a new age for motocross. Suzuki engineers used knowledge learned while creating fuel-injection systems for the LT-R450 QuadRacer ATV and the championship-winning GSX-R road race bikes to create the RM-Z450. The end result is the only mass-produced, fuel-injected motocross bike in existence, built to take on Honda’s CRF450R, the market leader in its category.
Kawasaki had to stay in the fight, so it created a machine with increased power delivery for better holeshot performance for 2008. The 2008 Kawasaki KX450F motocrosser is more dependable and easier to ride than ever thanks to a number of upgrades. The AMA and World Supercross GP Championship champion has been overhauled, with the new engine and better shifting being the standout features.
Honda started producing fuel-injected dirt bikes when?
The Honda had its largest redesign for 2017 since the introduction of fuel injection in 2009. With a titanium tank, a sixth generation aluminum frame was released.
How is the 2010 CRF250R?
It is a bike that rides well in the middle to the top, with plenty of power and traction to get you through.
In conclusion, the 2010 Honda CRF250R features a much enhanced engine with excellent response and isn’t afraid to cling on. Let the revs speak for themselves. Oh, and the twin exhaust is no longer present.
Honda introduced fuel injection when?
3 October 2003
Honda Programmed Fuel Injection, or “PGM-FI,” the first electronically controlled fuel injection system in the world, was created by Honda Motor Co., Ltd. for use in 4-stroke, 50cc engines.
Which Honda off-road vehicles use fuel injection?
Honda has experienced difficulties due to the ongoing CARB concerns in California and the EPA’s aggressive campaign against dirt bikes. Off-road motorcycles, ATVs, and side by sides create emissions (greenhouse gases) that are invisible when compared to commercial aircraft, cars, trucks, or even cow farts, but they are on us like pigs in their own swill. Why? Off-road vehicles may look back and tell the public, “Look what we accomplished,” since they are an easy target. Despite the fact that an aircraft taking off emits more gasses in a day than a fleet of dirt bikes does in a year or more (DBT Speculation- LOL).
The main drawback to staying current now is that it drives up the price of dirt bikes, which is already a concern for some. Honda showed no fear and now offers a whole line of off-road motorcycles that are legal in all 50 states, suitable for children up to big kids riding the brand-new CRF450X or CRF450L. Here is the most recent Honda press release highlighting their selection of exciting off-road play bikes.
CRF110F
Every child who watches Team Honda HRC factory riders Ken Roczen and Cole Seely on television or from a stadium seat feels the heart of a racer beating within them. With the brand-new, fuel-injected CRF110F, the technology and aesthetic of the CRF Performance Line have now made it to the motorcycle intended for younger riders. This model, which is 50-state off-road legal, comes with a Keihin electronic fuel-injection system for 2019. It is optimized for linear power delivery and precise throttle response. A brand-new steel twin-spar frame with CRF Performance Line DNA that has been rigorously researched and refined for the ideal blend of precision and comfort for recreational riders is paired with the more user-friendly power. A stable ride is provided by the agile chassis and seamless power delivery. The four-speed, clutch-less transmission for takeoffs and changing that rapidly becomes comfortable for every rider is carried over to the new CRF110F. Improved comfort is achieved either standing or sitting thanks to a 5mm increase in seat cushion thickness and a 12mm increase in rear suspension travel. The CRF110F, of course, has Honda’s renowned build quality and dependability, so it consistently starts when the starter button is depressed and keeps going until the tank runs out. When that time is approaching, the FI system illuminates a low-fuel warning light. The fuel-injection system’s ability to prevent the chance of the carburetor jets clogging with gasoline residue if the motorbike is left idle for a long time is a major advantage for the young rider’s “factory mechanic,” as less maintenance means more family time spent on the trail or track. Like its rider, the CRF110F combines elite performance in a compact design.
HRC LAUNCH CONTROL
We’re talking about a unique ECU program here: press the mode button, keep the throttle open, let go of the clutch, and the CRF250R will take care of the rest, giving you a significant advantage as you enter the first corner. It converts your bike into a machine for attempting holeshots!
ELECTRIC START
There is an easy electric starter on the CRF250R. It’s a big deal if you need to restart a stalled bike in the midst of battle; it’s convenient and lightweight.
The CRF250R from 2015 uses fuel injection.
Thanks to a new Engine Mode Button feature that let the rider to select between three distinct EFI/ignition maps, the fuel-injected four-stroke Single engine in the CRF250R is now easier than ever to adapt to track conditions.
Are fuel injectors used in 2013 CRF250Rs?
For enhanced low- and middle power, the CRF250R’s silencer works in tandem with the bike’s fuel-injection throttle body and injector. It is completely integrated into the engine tuning concept and is authorized for AMA racing.
When did the CRF250R receive an electric start?
The CRF250X and CRF450X are part of the CRF-X series as of 2014. Even though these bikes are electric-start and intended for off-road rather than motocross, they are still regarded as race bikes.
