In 2019, Honda released the CRF250RX, a brand new machine tailored to off-road riders and racers.

With designs rooted in the CRF250R and aspirations set to Yamaha’s YZ250FX and KTM’s 250 XC-F, the CRF250RX is a high-performer with great handling, awesome suspension, and good power. After a few months of putting it to the test, we came up with a few accessories that we feel the CRF250RX really needed to give it better performance, keep it protected, and fine-tune it to our riding style.

In this video and article, we’ll give you our take on the bike and go over a few of the essential parts we added to really take this bike to the next level.

Let’s get to it.

Engine

The 2019 CRF250RX’s engine requires a short introduction.

In 2018, Honda overhauled their CRF250R’s engine. It was generally well received, riders citing that it pulled really hard on top, but needed a little more bottom end. Honda took that feedback into consideration and made some refinements to their 2019 engine, i.e. the engine in the 2019 CRF250RX.

With that history in mind, we were excited to ride the stock 2019 CRF250RX to see how Honda’s new engine measured up. Our verdict? It didn’t disappoint – the bottom end was noticeably improved from 2018, it was decent in the mid, and was a screamer on the top. The bike seemed comparable to the KTM 250 XC-F, but didn’t quite reach the grunt of the YZ250FX. So, we set out to improve on the bottom end even more and add a few performance mods along the way.

First, we switched out the stock exhaust for dual FMF 4.1 RCT Anodized Titanium Silencers with Carbon End Caps. The FMFs are a top-of-the-line addition for the CRF250RX, helping the bike breathe better and just improving its all-around performance. Another bonus is that the silencers have the option for spark arrestors should any off road riders or racers need them. With off road riding and racing in mind, though, it’s worth noting that the FMFs are significantly louder than the stock exhaust – an expected tradeoff for the increase in performance, but a fact to be made aware of nonetheless. So, for anyone riding in sensitive areas, be sure to check that the FMF pipes don’t violate any sound restrictions.

With our exhaust breathing better, we moved onto our intake system and revamped it with the Twin Air Power Flow Intake System. This system completely replaces the stock cage, and even comes with an air filter with fire retardant foam. The new intake system, paired with the new silencers, made a noticeable difference, greatly improving the overall performance of the machine from top to bottom.

After the exhaust and intake were sorted out, we realized we were still running into a problem: In tedious and technical terrain, our bike was still flaming out and stalling. The solution? There were two things we did to remedy this:

  • Turn up the idle. This may seem like a no-brainer, but even the most experienced riders sometimes forget that something so simple can make a big difference.
  • Install the Hinson Momentum Clutch Basket. This is a more significant change, and therefore made a more significant impact. Coming in at 3 lbs. 4 oz., Hinson’s steel basket is almost double the weight of the stock basket. That weight gain may seem excessive to some, but it’s actually what makes the Hinson so effective. The extra weight acts similar to (if not the same as) a flywheel weight. As the motor is going, the weight provides more rotating mass on the driven gear, keeping the crank and piston moving and helping the motor chug through the slower, more technical stuff with ease.

Off-Road Accessories

Once we got our engine dialed in, we looked for some accessories to make our bike more off-road worthy.

2019 CRF250RX Bike Build

The first accessory we added was the Honda Showa Steering Stabilizer. It’s a natural fit for this Honda – the frame and triple clamp come compatible with it, and the front number plate perfectly hides it. With the reduced head shake, resistance in uneven terrain, and easy installation, the damper is a must on all of our off-road machines. This specific damper can be purchased via OE diagrams, but we also sell it as a kit containing all necessary bolts and hardware. We opted for the kit, mostly for the bolts and hardware – the damper works with an uncommon 7mm bolt, so be wary of that if you’re purchasing the stabilizer separately.

After installing the stabilizer, we added some Steg Pegz from Stegz. This bolt-on accessory may not seem like a necessity, but it truly revolutionizes the ride. Steg Pegz work with a lightweight yet strong bracket and a small rubber disc. Positioned right behind the calf of your boot, the pegs grip your boot when you stand up on your foot pegs, supporting your weight and alleviating stress on your arms. They’re a life saver in any technical and gnarly riding situations – we’ve even used them in desert races. It doesn’t take more than one ride to get used to them, and we’re likely to have them on all of our off-road bikes going forward.

Protection

Next up were some extra protection items for our new-and-improved CRF250RX. We started with the Cycra Full Armor Skid Plate. Out of all the skid plates we’ve tried, Cycra’s is one of the toughest. It’s thick, gives the best coverage, and has withstood every beating we’ve given it.

That being said, there is one qualm we have: the plate’s drain hole doesn’t line up with the bike’s drain bolt. This is a minor inconvenience, but it’s worth mentioning. For us though, the Cycra was well worth it, and we opt to just take off the skid plate when it’s time for an oil change rather than drill a hole (which is still something that could easily be done).

The second protection upgrade we made was the Tusk D-Flex Pro Handguards. These handguards are a staple for us, and we run them on just about all of our bikes. There’s just something about the durability, reliability, toughness, and coverage that keep us coming back every time – the D-Flex handguards are truly unmatched.

Another safety measure we took was adding the Baja Designs Squadron Pro Single LED Light. Since we like riding through summer nights and in the dark, this light is a great feature to have. Mounting right in the corner of the front number plate and with an LED life expectancy of 49,930 hours, the light gives us the peace of mind we need to ride long past the sunset.

Performance

To give our bike even more of an off-road edge, we freshened it up with the Tusk Recon Hybrid tire. While this tire hit our site not too long ago, it’s nothing new to us – a bona fide “tried and true” product, we’ve put thousands of miles on these tires, optimizing their design and performance. In the end, we couldn’t be happier with or prouder of the results. Any off-road or technical rider knows what a game-changer hybrid tires can be, and the Tusk offering is no exception.

The tires are super gummy, giving riders confidence in all of that rough, rocky, and rooty stuff and keeping the bike from getting kicked around. That said, the tires still hold up well in aggressive corners and hard accelerations and don’t feel squirrely or unreliable in the slightest.

With the Tusk tires hooking up so well and holding it down at high speeds, we decided to add the Tusk Radiator Fan Kit as a safeguard. Just because our tires can go all day doesn’t mean our engine can – at least not on its own. Tusk’s fan kit reads your engine’s temperature and kicks on at the degree you set, cooling the bike down to a safe running temperature. For us, we set our fan to kick on at 190°F and turn off once the engine reaches 185°F. What’s more, this all comes in a high-quality, reliable Panasonic motor, making the Tusk fan comparable to most factory kits.

2019 CRF250RX Bike Build

A fan kit really is a must for technical, tough, aggressive riders as it gives you confidence that you won’t overheat or overwork your bike. That’s why we made the Tusk kit so affordable – it’s a necessity for hard working weekend warriors like us, and one that can be purchased without breaking the bank or breaking after the first use.

The Wrap-Up

With those engine upgrades, off-road accessories, protection additions, and performance enhancements, our 2019 CRF250RX is refined and ready to rip. We liked the bike before, but now we’re in love and are already looking forward to where Honda will take this bike in future years.
