Honda engineers set a goal for 2009 to build a CRF450R that was lighter than its predecessor while still using electronic fuel injection. The third-generation CRF450R is the outcome of their work. This brand-new model, which benefited from a strong emphasis on weight reduction and mass centralization, was distinguished by a redesigned twin-spar aluminum frame with numerous design improvements, including a relocated steering head, a reduced overall height, and revised geometry. These modifications, along with an entirely new, smaller engine, led to the creation of a motorcycle that was renowned for its nimble handling and powerful reactivity off the bottom.

When did fuel injection come to dirt bikes?
In 2002, the first fuel injection dirt bike hit the market. Today, a larger percentage of four-stroke motocross and enduro/trail bikes use this technology. However, there is still a lot of misinformation and, should we say it, outright ignorance at the foundation of skepticism regarding the dependability of EFI systems and the longevity of their componentry.
Therefore, to clear up some of the most prevalent fuel injection misunderstandings, we interviewed some of the top engine tuners and race team technicians in the nation and recorded their aggregate insights.
When did 250 dirt bikes start using fuel injection?
The CRF-F series consists of the CRF50F, CRF110F, CRF125F (Big Wheel), CRF230F, and CRF250F as of 2021.
The CRF 110F, CRF 125F, and CRF 250F all include electronic fuel injection as standard equipment for the 2019 model year. Because there is no carburetor to clean, this facilitates starting in cold weather and makes the bike easier to maintain.
simple 4-stroke motorcycles with air cooling. For new market entrants, these bikes typically come in low-power and self-assured variants.
The Honda CRF50F, CRF70F, CRF80F, CRF100F, CRF110F, CRF125F, CRF125FB, CRF150F, CRF230F, and CRF250F are all models that have been produced.
There are no longer any CRF70F, CRF80F, CRF100F, CRF150F, or CRF230F models available. The 110 replaced the 70, the 80 and the 100, the 125 took the place of the 150F, and the 230 was swapped out for the 250F.
What year was fuel injection added to the Honda crf250?
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.
- Aluminum frame with Progressive Steering Damper (HPSD)
- A brand-new shock body and upper and lower fork tubes were created specifically for the CRF250R chassis, and there is a brand-new front and rear suspension as well.
- Automatic Fuel Injection (PGM-FI).
- Improved filter access is provided by a redesigned, larger airbox with expanded capacity for better breathing and more power.
- a brand-new, smaller engine.
- Mass centralization is improved with a brand-new single-muffler exhaust system.
- entirely new bodywork
- Unicam 249cc liquid-cooled four-valve engine.
- brand-new little engine.
- Completely revised engine delivers increased power from a noticeably smaller package, which lowers the center of gravity and improves mass centralization for better handling.
Are fuel injectors used in 2009 CRF 250?
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.
Honda stopped utilizing carburetors in motorcycles at what point?
At the end of 2002, Honda finished converting all of its motorcycles (with the exception of a few specialized models) to 4-stroke engines as part of its continued efforts to help protect the environment.
Which Honda motorcycles use fuel injection?
Honda’s brand-new, fuel-injected, MX-inspired CRF110F, CRF125F, and CRF125FB motorcycles are now on sale in dealerships around the nation. The 2019 CRF110F, CRF125F, and CRF125FB all have major performance and aesthetic improvements and are available for an MLP of $3,299, $4,199, and $4,599, respectively.
All three models include technological advancements developed from Honda’s renowned CRF MX lineup, including electronically regulated fuel-injection systems from Keihin that produce power that is linear and jerk-free. This reduces fear among novice riders and offers a welcoming power delivery for all abilities. These new children’s bikes feature updated twin-spar steel frames and graphics that are also influenced by the frame construction of the CRF MX range, which offers the ideal combination of comfort and rigidity as well as a genuine MX appearance. 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 124.9cc SOHC engine and four-speed gearbox from the CRF125F and CRF125FB remain unchanged, providing powerful power and easy shifting. The CRF125FB has a 46mm variation in seat height from the CRF125F due to hardware differences in the wheel size, swingarm length, and final-drive gearing. The three vehicles all include new handlebar-mounted multiple-function switches that include a starter button, an indicator for when the ignition key is on, a status light for the fuel-injection system, and a low fuel indicator light. The half-waffle handgrips have a smaller radius for a better fit with tiny hands, and the new ratchet-style fuel tank cover lowers the danger of loosening while riding.

- Honda added new White and Black/Flame colors to the 2007 TRX450R electric-start models.
- Reflectors were modified for better visibility and a more recognizable design.
Although a fuel-injected 2018 Honda TRX450R was supposed to be coming out as early as 2009, the trim tragically never saw the light of day. The 2014 Honda TRX450R was the final model built under the SporTrax brand. Although ardent Honda fans hoped for a version that was simpler to handle, faster, and more dependable, it did contain all the aforementioned engine and aesthetic improvements.
Is a TRX450R from 2008 fuel-injected?
Suzuki’s QuadRacer 450 is one of only three 450s in its class (the other two being Kawasaki 450 and Can-Am DS450) to include electronic fuel injection and is the only 450 on the market with a broader stance suitable for motocross.
A 2009 Honda CRF 450r has fuel injection, right?
The 2009 CRF450R also features a Honda first – battery-free, programmed fuel injection that increases output power and control while drastically lowering fuel consumption. It is lighter, faster, more powerful, and has even tighter mass centralization for quick handling.
Which dirt bike has ever been the best?
With a 360cc engine, the YZ360 is among the most potent dirt bikes ever produced. It was also one of the very few “work” bikes produced at the time, meaning that it was designed with racing in mind. It was renowned for being able to withstand a lot of abuse on the track while having a light structure. Additionally, it introduced the monoshock suspension system for dirt bikes, which increased driver stability.
In addition to having a lot of power, this Yamaha bike was also quite rare, which added to its appeal. It was more expensive than other dirt bikes in the 1970s and was only made in extremely small quantities. Each of these bikes costs $1700, which translates to just over $11,000 in today’s dollars after accounting for inflation.
Exactly which 250cc dirt bikes have fuel injection?
The fuel-injected two-stroke dirt bike from Husqvarna, the TE250i, has an electric start and has the potential to revolutionize trail and enduro riding. Husqvarna released the eagerly anticipated fuel-injected two-stroke TE250i dirt bike before its sister firm, KTM, did.
Is a carburetor or fuel injection better?
- Performance and strength. Once more, because current electronic controls and fuel injection are more precise, fuel supply may be adjusted to match driver demand. In that they cannot take into account changes in air or fuel temperature or atmospheric pressure, carburetors are precise but not exact.
- fuel economy and emissions. Gasoline injection started to replace the carburetor in the 1970s because it can be more precisely controlled, resulting in more effective use of fuel, lower fuel consumption, and fewer emissions.
- intricacy and price. Carburetors are far more expensive and sophisticated than fuel injection because they are only mechanical devices. You can repair a carburetor on your porch or at a rest area with a can of carburetor cleaner, some basic hand tools, and possibly a few extra components. In contrast, if you have a fuel injection system that fails, even with years of training, experience, and expensive diagnostic equipment, you will need a tow truck to get you off the road. Due to the fact that most tiny engines, such as those found on motorcycles, lawn mowers, and snowblowers, are not subject to pollution regulations and are instead low-cost, straightforward, and dependable, carburetors are still a common feature.
Fuel injection is unquestionably a better choice, offering more power, fuel efficiency, and reduced pollutants, even though the carburetor has been around for more than a century. This is everything a modern driver might want.

What exactly does KTM mean?
The company’s preference for using initials for model names is not surprising given that its name, KTM—Kronreif & Trunkenpolz Mattighofen—stands for Kronreif & Trunkenpolz Mattighofen. It would be simple to claim that street bikes have traditional names, whereas dirt bikes have letter model names. You’ll soon realize that it’s not quite that easy. The Enduro portfolio doesn’t even include the Enduro R variant. Additionally, special editions may deviate from the naming scheme, but let’s save that discussion for another time. Even if we are unable to simplify the KTM alphabet soup, we will try our best to explain it.
A 2011 CRF 250r is fuel injected, right?
The 250 four-stroke with screaming fuel injection was simple to ride and, more crucially, simple to ride quickly. On the track, however, it left us a little perplexed. For strong charging motocross, the suspension felt a little flimsy at both ends, and the engine lacked the immediate snarl that pros love.
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.
